Figure 1. 619DSRI front view Figure 2 shows the back panel of the 619DSRI, which includes power connectors, connectors for data ports, and connectors for digital I/O and CTCSS signals. Figure 2. 619DSRI back view 619DSRI – Product Manual 1 Chapter 1 The 619DSRI is an eight-port radio communications hub that is designed to provide cost-effective interoperability between radios from different manufacturers and different RF systems. It incorporates a variety of signal processing and control techniques and is user configurable with the built-in web server called the Configuration Interface—the PC-based SRI Configuration Utility is no longer supported. Features The 619DSRI provides the following features: ● Ability to change the audio routing configuration dynamically ● Interconnection of disparate radio systems ● Support for CTCSS and in-band keying tones, and fast CTCSS input to output keying ● Support for CTCSS steering through the network by creating separate paths for voice and data ● Sub-dividing of ports to create independent networks ● Adjustable timings on individual ports to suit the radio network ● Remote control of the unit using DTMF and Selcall sequences ● Ability to upgrade the software via an Ethernet connection ● Interoperability between public organizations ● Dynamic configuration in emergency situations or to meet peak traffic demands ● Flexibility in forming groups of users ● V.23 DSP modem for data communications and remote configuration over radio Key Hardware Features The 619DSRI hardware is based on the success of its predecessor, the 619SRI, but is completely redesigned from the ground up to make use of the latest in digital signal processing (DSP) technology and eliminates the need for physical hardware links. The key hardware features include: 2 • Standard 19-inch rack unit (1RU) with eight independent 4-wire analog E & M ports • Operation from 12VDC to 24VDC • 2-line by 16-character dot-matrix backlit LCD panel for status and diagnostics • Independent signal encoders and decoders on all eight ports • Signal processing circuits for CTCSS, In-band keying tones, selcall, DTMF, VOX operation, and tone generation up to 1kHz • Simultaneous signal detection and generation on each port • Remote control capability using SELCALL and DTMF • Digital level control of all signal inputs and outputs • Opto-isolated busy (COS) inputs with contact, voltage, and switched options, and opto-isolated auxiliary digital inputs • Isolated PTT outputs with contact, voltage, and switched options • Transformer isolated line audio • Dual analog inputs for monitoring applications and dual relay outputs with changeover contacts for control applications • 10/100Mbit Ethernet port with auto-MDIX detection Introducing the Digital Smart Radio Interface Key Software Features The 619DSRI operation is completely configurable using the web-based interface and a web browser. Using the software configuration features, you can: • Control the mapping of Busy Input to PTT Output operations by programming a primary and a secondary configuration. • Modify the primary and secondary configurations by overlaying up to 6 optional overlay configurations. • Invoke different configurations using digital inputs, CTCSS, in-band tones, DTMF tones, or SELCALL. • Set up each port to accept incoming signals with qualification of a CTCSS tone, or in-band keying tone. • Invoke a specified configuration immediately on reception of a Busy input with the Fast Output feature. • Configure the 619DSRI to act as a CTCSS repeater by detecting up to 15 consecutive CTCSS tones and transmitting on an output port with the audio. • Set up a group of inputs with the First-In First Served feature in which the first input detected locks out the other inputs in the group preventing unintentional configuration changes. • Change the base configuration from primary to secondary or secondary to primary with the System Split feature and DTMF or SELCALL. • Set up a heartbeat schedule for a specific period of the day to generate a single tone or mixed with a CTCSS or in-band tone. • Control the operation of the PTT outputs by adjusting timing parameters such as the PTT hold, PTT leadin, and the PTT timeout. • Control the operation of the Busy inputs by adjusting busy validation timing to help equalize network propagation delays. • Easily generate CTCSS on port outputs with the Follow Input feature according to the mapping configured and an inbound CTCSS signal. • Superimpose a tail tone on port outputs with the Tail Tone feature. • Control the CTCSS switch off with the Soft Key-Off feature to help prevent tail noise when the PTT switches off. • Configure the operation of the two output relays with the Relay Control feature. • Dynamically change the transmit levels of the encoders, and the receive and transmit levels on the ports. • Control various functions using preset DTMF commands or programmable SELCALL commands. • Backup and restore configuration settings stored in a configuration file on a local hard disk. • Change the configuration either locally or remotely using the web-based interface. 619 Digital Smart Radio Interface – Product Manual 3 Chapter 2 Overview of the Digital Smart Radio Interface This chapter provides an overview of the 619DSRI (Digital Smart Radio Interface), and includes the following sections: ● “Multi-Level Menu System” ● “Multi-Function LCD” on page 8 ● “Using the Menu Button” on page 8 ● “Modes of Operation” on page 9 ● “Resetting to Factory Default Settings” on page 12 ● “Upgrading the Firmware” on page 12 ● “Audio Bridging” on page 13 ● “Functional Overview of the 619DSRI” on page 15 ● “CTCSS and In-band Signals” on page 18 Multi-Level Menu System The 619DSRI provides a sophisticated menu system with a multi-level menu structure, as depicted in Figure 3 and Figure 4 on the following pages. You use the menu mode for navigating the menu structure and for viewing and configuring the various settings. Menu mode is discussed in the section Menu Mode and Navigating the Menus on page 10. As shown in Figure 3, at power up (A), the 619DSRI displays the revision of firmware stored in the on-board EEPROM, and after about 2 seconds, the Busy and PTT levels (B) will be displayed. The 619DSRI is now in the normal mode of operation. In this mode, when any of the Busy inputs or the PTT outputs on a port changes state, it will appear on the display. Pressing the MENU button enters menu mode and displays the Digital SRI Functions menu (C). The operation of the MENU button is discussed in the section “Using the Menu Button” on page 8. 619DSRI – Product Manual 5 Figure 3. 619DSRI multi-level menu structure (page 1) Chapter 2 6 Overview of the Digital Smart Radio Interface 619DSRI – Product Manual 7 Figure 4. 619DSRI multi-level menu structure (page 2) Chapter 2 Multi-Function LCD Located on the front panel of the 619DSRI is the 2-line by 16-character back-lit dot-matrix LCD, which provides various functions such as access to a multi-level menu system for performing basic configuration of the 619DSRI, and displaying the current status of the active inputs and outputs (see Figure 1). At power-up, the 619DSRI loads its configuration from Flash memory and performs various startup and initialization functions.

Typically, this may be due to inconsistent network settings. You can use the following procedure to reset the 619DSRI to default settings should it fail to start up correctly. To reset the 619DSRI to default settings 1. Disconnect the power source to the 619DSRI. 2. Press and hold the MENU button on the front panel of the 619DSRI. 3. Reconnect power to the 619DSRI. 4. Continue to press and hold the MENU button for about 20 seconds while the 619DSRI completes its startup sequence. The 619DSRI should display the following messages as it resets its configuration to defaults:              The 619DSRI should now be reset to its default configuration settings. Upgrading the Firmware The firmware in the 619DSRI is stored in Flash memory so that it can be upgraded with a new version of the firmware when it becomes available. Omnitronics periodically provides upgrades to the firmware to resolve issues with its operation or to provide enhancements and additional functionality. Using the built-in configuration interface, you can easily upgrade the firmware in the 619DSRI when a new version becomes available. Note When upgrading the firmware, all configuration settings are maintained and not reset to defaults. Figure 12 shows the messages that appear on the LCD when upgrading the firmware using the configuration interface.             LCD alternates between both screens at 2-second intervals until the firmware upgrade is complete. Figure 12. Messages shown on the LCD when upgrading the firmware 12 Overview of the Digital Smart Radio Interface Audio Bridging Audio bridging comprises audio mixing and audio routing. Fundamentally, audio bridging is the function of combining (or mixing) a number of analog audio signal sources together to form a mixed product. Additionally, bridging must allow for balancing the levels of the different audio sources prior to mixing. In radio systems, audio bridging also involves combining control signals, such as the Busy (COS) output from each source radio to form a control PTT signal. Omnitronics audio bridges extend these basic functions even further to provide audio routing. Audio bridging, on its own, is of limited value. However, by incorporating a switching matrix, Omnitronics audio bridges extend this basic functionality by providing a programmable routing function. This allows you to set up a number of inputs-to-output configurations and easily change these configurations as required. Bridging Matrix At the core of every Omnitronics Audio Bridge is a bridging matrix. The bridging matrix comprises a switch matrix with transmit-side mixers. Figure 13 shows a block diagram of the bridging matrix concept using a simple four-port bridge. Figure 13. Block diagram of audio bridging matrix Each port input (PORT n IN) can be considered to be the received audio and the COS signal from a source such as a radio. The matrix specifies the routing configuration and controls the transmit-side mixers. The output side contains the transmit-audio and PTT signal. In the example depicted in Figure 13, we see that (PORT 4 OUT) is configured to transmit the mixed audio received from Ports 1, 2, and 3 through switches 4-1, 4-2, and 4-3. Furthermore, the PORT 1 IN received audio is routed through switch 1-1 to PORT 1 OUT and to PORT 4 Out through switch 4-1. By changing the configuration of the switches in the matrix, the mixing products and routing destinations can be altered. With the 619DSRI, the switching matrix is controlled through software; this enables the product to support dynamic configuration. 619DSRI – Product Manual 13 Chapter 2 Programmable Control Matrix One of the main functions required for interoperability is the ability to interconnect disparate radio equipment as required. The 619DSRI may be programmed with eight input-to-output configurations. Using Dynamic Hub Control Technology (DHC), the 619DSRI configurations may be altered dynamically according to input conditions, thus allowing the 619DSRI to perform functions such as CTCSS steering. Fundamentally, DHC technology provides two base configurations and six overlays. The overlays can be invoked by change events to dynamically make or break link paths in the base configuration. A change event can be a digital input, a received CTCSS tone, a received in-band keying tone (i.e. 2600Hz), or a DTMF or SELCALL command. Figure 14 shows an example of setting up the programmable control matrix with overlays using the built-in web server to configure the programmable control matrix (refer to “Chapter 4, DSRI Matrix Configuration” on page 57 for further information). Figure 14. Using the web-based interface to configure the programmable control matrix 14 Overview of the Digital Smart Radio Interface Functional Overview of the 619DSRI This section provides a functional overview of the operation of the 619DSRI. Figure 15 shows a block diagram of the functional overview of the 619DSRI. Figure 15. Block diagram of the functional overview of the 619SRI Audio Line In and Audio Line Out Receive and transmit audio for each of the eight ports has programmable level adjustment over a wide range of levels. Adjustments can be made remotely over the air or through a data link. E & M options cater for many Busy (COS) and PTT configurations. VOX/CTCSS/In-band Decoders Each port has a dedicated signal detector that supports CTCSS and in-band keying tones. It also provides a VOX function for use with HF radios or audio bearers. The CTCSS tones are programmable on a per-port basis. CTCSS/In-band Encoders Each port has a dedicated signal generator that can transmit programmable CTCSS and In-band keying tones. The transmitter section works independently of the receiver section, allowing CTCSS translation and signal protocol conversion. Each CTCSS signal can be directed either to the main line out where it is mixed with the TX audio, or to a separate output on a DB25 connector. 619DSRI – Product Manual 15 Chapter 2 DTMF Encoder/Decoder A DTMF transceiver provides the ability to control functions of the 619DSRI remotely. The decoder acts on the mixed audio input to the unit. The encoder can be switched into one or more of the output ports. SELCALL Decoder In a similar manner to the DTMF function, the signal detector of Port-8 can be configured to remotely control the 619DSRI. The decoder uses the mixed audio input to the unit. V.23 DSP Modem The V.23 DSP modem functionality was carried over from the older “SRI” product to support a legacy application. It is not recommended for use in new applications. The configuration interface now provides remote configuration functionality. Tone Generator A tone generator provides a frequency range: 460Hz and 700Hz. These are used by the system to provide audible confirmation for remote requests and for generating PTT tail tones. Real-Time Clock The real-time clock enables you to schedule heartbeat or voting tones over a specific 24-hour period. If you notice that the Real-time Clock gains or loses time, you can adjust the setting with the Menu knob on the front panel. The setting allows you to specify a value (in seconds) that can be used to adjust the time. You can set a value from -30 to +30 seconds on the DSRI and 0 to 59 seconds on the SRI. At midnight, the real-time clock will be corrected by the number of seconds that you specify. Auxiliary I/O The 619DSRI provides two analog inputs and eight opto-isolated digital inputs. The digital inputs may be optionally used to perform dynamic switching functions. However, they can also be used with the analog inputs for site monitoring purposes. Two relay outputs are also available for pre-programmed functions or for manual remote control. Configuration You can configure the 619DSRI using the configuration interface via the Ethernet connector. Diagnostic I/O Connectors on the rear panel provide access to the radio network for the technician on site. An internal Audio Loopback, Test Tone, Local PTT, DTMF, and Selcall sequence can be generated to any of the 8 ports through the user interface. 16 Overview of the Digital Smart Radio Interface Audio Path Figure 16 shows a block diagram of audio entering the 619DSRI at each of the eight 4-wire E & M line ports that is attenuated or amplified by digital potentiometers. Each input is fed into a signal processor which performs two functions: the ● Detection of CTCSS and In-band signals ● Band-pass filtering (300 Hz to 3 kHz) Other audio to mix Notch Filter LINE IN LINE OUT 1 0 Codec IN Notch Filter 1 Detector Tone/CTCSS 1. In-band decode Codec OUT HPF Audio Bus 2. O/P tone control 3. O/P in-band tone 0 Figure 16. Block diagram of the audio paths through the 619DSRI The following provides an explanation of the audio processing: 1. Audio IN (RX_AUDIO) - the audio bandwidth should be 10 to 3600 Hz. a. Signal is fed straight to the detector for CTCSS or SELCALL. b. If in-band signal detection (i.e. 2600Hz) is enabled for this port then the input must be notched before it proceeds to the audio bus. 2. Audio OUT a. Audio sources from the bus may need a high pass filter if a CTCSS is to be generated on the output. The O/P tone control setting will determine this. Filter should be > 254.1Hz. b. This allows inputs with CTCSS to be routed to outputs without the original CTCSS being stripped out. c. If the output is to include an in-band tone (i.e. 2600Hz) then that frequency must be filtered from the out-going audio. Therefore, a notch filter is required if the O/P tone control setting specifies an inband tone. d. Multiple audio sources are mixed at the final output stage. 619DSRI – Product Manual 17 Chapter 2 CTCSS and In-band Signals This section describes the CTCSS and in-band signals. Each port can decode and generate various signaling tones. This includes both sub-audible CTCSS and in-band signals. Sub-Audible CTCSS CTCSS can be detected for the purpose of: • Controlling (or steering) the audio device via one or two frequencies. On reception of a specific CTCSS frequency, the device configuration is changed. The configuration is normally restored when the input signal terminates. • Qualifying a received audio signal. This ensures that an incoming audio signal is only passed to the audio matrix if it has been superimposed with a specific CTCSS tone. • Performing a simple repeater function. This accepts an incoming audio signal only if it has been superimposed with one of the 45 pre-programmed CTCSS tones. The detected CTCSS frequency will be present on the output when the output is set to No Tone. In-band Keying Tones Each port can be configured to detect or generate any one of the following keying tones: ● 2175Hz ● 2325Hz ● 2500Hz ● 2600Hz ● 2970Hz SELCALL SELCALL is used to provide a control function for the 619DSRI. This allows radio users to change the configuration of the device remotely using a SELCALL string. Digital CTCSS The device can also accept digital CTCSS signals through the Digital I/O (DB25) connector on the rear panel. The selection of the type of signal to be processed is made through software set up using the Software Control Options. 18 Overview of the Digital Smart Radio Interface Chapter 3 Getting Started This chapter contains step-by-step instructions for connecting the 619DSRI to the network to get it up and running quickly. All settings of the 619DSRI are configured using the configuration interface built into the 619DSRI product. This chapter contains the following sections: ● “Connecting to the Network” ● “Connecting with Windows” on page 20 ● “Connecting with Mac OS X or Linux” on page 24 Connecting to the Network The 619DSRI includes a built-in web server that provides a configuration and management interface known as the configuration interface. However, before you can access the configuration interface, you need to ensure that your computer and the 619DSRI product are both using compatible IP addresses. If the IP address of your computer does not have a similar address (e.g. the IP subnets are different), it will not be able to communicate with a 619DSRI that is using the factory default address. All 619DSRI devices leave the factory configured with an IP address of 192.168.0.180. If the IP address of your computer does not have a similar address (i.e., an IP address starting with 192.168.0.x), you will need to temporarily change the IP address of your computer to a compatible address before it can connect to the 619DSRI by following the steps in the procedure below that is applicable to your operating system. The recommended method of connecting the 619DSRI and a computer via an Ethernet network is to use an Ethernet switch or router. However, for the purpose of connecting a factory default 619DSRI for the first time, you can connect the computer directly to the 619DSRI using an Ethernet network cable—you do not need to use a cross-over cable as the Ethernet port is MDIX compatible and can auto-detect the line condition. You can then access the configuration interface and configure the network settings of the 619DSRI to match your network. The Ethernet port is located on the front panel of the 619DSRI, as shown in Figure 1. When connecting Ethernet cable from the 619DSRI to the Ethernet switch or router, the Link indicator on the front panel illuminate. If this indicator does not illuminate, it may indicative of a problem with the network cable; and computer will not be able to communicate with the 619DSRI until you correct the problem. This indicator flash whenever the 619DSRI detects a activity on the network. 619DSRI – Product Manual the will the will 19 Chapter 3 Connecting with Windows This section contains basic information to help get your 619DSRI up and running quickly using Microsoft ® Windows 7. However, the same steps will also apply to Windows 8.1 and Windows 10. ® All settings of the 619DSRI can be set using the built-in web server, which provides a sophisticated and easyto-use configuration interface. However, before you can access the configuration interface, you need to ensure that your computer and the 619DSRI device are both using compatible IP addresses. All 619DSRI products leave the factory configured with an IP address of 192.168.0.180. If the IP address of your computer does not have a compatible address (that is, an IP address starting with 192.168.0.x), you will need to temporarily change the IP address of your computer before it can connect to the 619DSRI by following the steps below. Note To change the IP address of your computer, you must be logged in with a user account that has administrator priviledges. Step 1: Determine the IP address of your computer You can determine the address of your computer by following the procedure below. To determine the IP address of your computer 1. On the Start menu, click Control Panel. 2. Click Network and Internet. 20 Getting Started 3. On the Network and Internet window, click Network and Sharing Center. 4. Under View your active networks, click Local Area Connection to open the Local Area Connection Status dialog. 5. Click Details to display the Network Connection Details dialog. 619 Digital Smart Radio Interface – User’s Guide 21 Chapter 3 The Network Connection Details shows the various settings for the network. The settings of interest are the IPv4 IP Address, the IPv4 Subnet Mask and the IPv4 Default Gateway. 6. Record the details for IPv4 IP Address, IPv4 Subnet Mask, and IPv4 Default Gateway from the Network Connection Details, then and click Close. Step 2: Change the IP settings of your computer Before you can connect to the 619DSRI, you need to temporarily change the IP settings of your computer to match the IP settings of the 619DSRI. If the IPv4 Address of your computer (see “Step 1: Determine the IP address of your computer” on page 20) starts with the numbers 192.168.0.x and the IPv4 Subnet Mask is 255.255.255.0, your computer is using a compatible IP address and it will be able to communicate with the 619DSRI without any changes to its IP settings. In this case, you can skip to “Step 3: Connect the 619DSRI to the computer” on page 23. However, if the IPv4 Address of your computer does not start with the numbers 192.168.0.x, it will be necessary to temporarily change the IP address of your computer. Important Ensure you record the current IP settings so that you can restore your computer to its original configuration after you have finished configuring the IPR400 device. To change the IP settings on your computer 1. In the Local Area Connection Status dialog, click Properties. The Local Area Connection Properties dialog is displayed. 22 Getting Started 2. In the This connection uses the following items list, select Internet Protocol Version 4(TCP/IPv4), and then click Properties. The Internet Protocol Version 4 (TCP/IPv4) Properties dialog is displayed. 3. Under the General tab, select Use the following IP address and enter the following details: ● IP address is the static IP address you want to assign to your computer. ● Subnet mask is the subnet mask used by your router. ● Default gateway is the IP address of the default gateway. 4. Click OK. The changes will take effect immediately; it should not be necessary to restart your computer. Step 3: Connect the 619DSRI to the computer This step connects the 619DSRI to the computer via an Ethernet network. The recommended method of doing this is to use an Ethernet switch or router. However, if such a switch or router is not available, you may connect the computer directly to the 619DSRI using an Ethernet cable. Note You do not need to use a cross-over cable for direct connection. When connecting the Ethernet cable from the 619DSRI to the Ethernet switch or router, the Link indicator will illuminate. If this indicator does not illuminate, you may have a problem with the network cable; and the computer will not be able to communicate with the 619DSRI until you correct the problem. 619 Digital Smart Radio Interface – User’s Guide 23 Chapter 3 Step 4: Configure the 619DSRI network settings This step uses the configuration interface to configure the network settings of the 619DSRI. To configure the 619DSRI network settings 1. Start your web browser and type the IP address (192.168.0.180) of the 619DSRI device in the address bar. Note All 619DSRI devices leave the factory configured with an IP address of 192.168.0.180. The configuration interface should show the log-in page similar to the one shown below. 2. Configure the network settings of the 619DSRI to match the network settings of your computer network. Note For details on how to configure the network settings of the 619DSRI, refer to “Chapter 4, Configuring the TCP/IP Network Settings” on page 36. Step 5: Restore the network settings of the computer Once you have configured the network settings of the 619DSRI device, you can restore the network settings of your computer back to the original settings. Note If you did not need to change the network settings of your computer, you do not need to perform this step. Repeat “Step 2: Change the IP settings of your computer” on page 22 to restore the network settings of your computer back to its original settings that you recorded in “Step 1: Determine the IP address of your computer” on page 20. This time, however, you’ll change the IP address, Subnet mask, and the Default gateway to the original settings. Congratulations! You have now configured the 619DSRI to communicate on your network, and you should now be able to connect to the 619DSRI using the original network settings of your computer. Connecting with Mac OS X or Linux For other operating systems, the same basic steps are necessary: change your computer’s IP address to one in the same subnet as the 619DSRI, such as 192.168.0.x, then access the 619DSRI configuration interface to change its IP address, and then save the configuration and restart. 24 Getting Started Chapter 4 Using the Configuration Interface The 619DSRI is a versatile device that allows you to configure its operation by making changes to configuration settings. The 619DSRI provides a built-in web server called the configuration interface that you can use to configure it; the 619DSRI can be configured within the LAN or WAN environment via a web browser using password-protected access. This chapter includes the following sections: ● “What is the Configuration Interface?” ● “Using the Configuration Interface” on page 26 ● “Viewing the System Status” on page 34 ● “Configuring the TCP/IP Network Settings” on page 36 ● “Changing the Password” on page 39 ● “Backing up and Restoring the Configuration” on page 42 ● “DSRI General Configuration” on page 44 ● “DSRI Matrix Configuration” on page 57 ● “DSRI Input Control Configuration” on page 62 ● “DSRI Output Control Configuration” on page 69 ● “DSRI Alarms Configuration” on page 71 ● “DSRI Heartbeat Configuration” on page 74 ● “Levels Configuration” on page 76 ● “Timing Configuration” on page 79 ● “E & M Configuration” on page 85 What is the Configuration Interface? The 619DSRI includes a web server that provides a configuration and management interface called the configuration interface. This interface uses standard HTML, and should be compatible with most web browsers. The web-based configuration interface consists of a series of web pages designed to help you configure the 619DSRI. Using the configuration interface, you can access all the status information, configuration settings, and diagnostic tools in one convenient user interface. The configuration interface is compatible with the following web browsers, and it should also be compatible with later versions: ● ● ® Internet Explorer 9 – 11 ® Firefox 3 and later ● Google Chrome 14 and later ● Safari 5 and later NOTE: Chrome and Safari web browsers have not been fully tested but may work correctly. 619DSRI – Product Manual 25 Chapter 4 Using the Configuration Interface All configuration and management of the 619DSRI is done using the built-in configuration interface. This is a web-based configuration interface that you can access using your web browser. Before you can use the configuration interface, however, you must first log on to the 619DSRI. You can then access the various configuration pages by clicking on the menus located on the left side of the web interface: selecting a menu displays the corresponding page on the right side of the web interface. The 619DSRI must be connected to an Ethernet computer network using the standard RJ45 network connector on the front panel. Once it is physically connected to the network, you must be able to navigate to the log-in page using your web browser. To do this, however, you need to know the IP address of the 619DSRI so you can connect to it using your web browser. If you are configuring the 619DSRI for first time, you can use the default IP address and type http://192.168.0.180 into the address bar of your web browser. This will load the log-in page in your web browser. Tip If you do not know the IP address of the 619DSRI, you can use the built-in menu system with the MENU button and LCD on the front panel to access the Network Functions and check the network settings. If UPnP is enabled in the 619DSRI, you should be able to discover the 619DSRI on your network: its device name (e.g. DSRI, Name: DSRI-11010841, V5.09.00) will appear under the My Network Places on a computer running the Microsoft Windows operating system. Once you have located the device, double-click on it to automatically load the log-in page into your web browser. Note To discover the 619DSRI on your network, the network settings of the 619DSRI must match those of the computer used to access the 619DSRI. That is, the IP address of the 619DSRI must be on the same sub-net as the IP address of the computer. This section discusses how to use the built-in configuration interface to set up the user accounts and to configure the settings of the 619DSRI. User Accounts and Logging In Before you can use the configuration interface, you must first “log in” using one of the built-in user accounts. Depending on the user account you use, you can either access all configuration pages used to view and configure the 619DSRI, or just a subset of the pages. The configuration interface provides several types of user accounts: • Supervisor Account provides full access to the configuration settings and allows supervisors to configure all aspects of the 619DSRI. • Technician Account provides access to only the System Status page and the Radio Diagnostics page. • Limited User Account provides access to only the System Status page. To use the web-based configuration, launch your web browser and use the IP address of the 619DSRI (i.e. either the factory default IP address if configuring for the first time, or the IP address you configured in “Chapter 3, Connecting to the Network”) to access the configuration pages. For example, if using the default IP address, type http://192.168.0.180 in the address bar of the browser 26 Using the Configuration Interface Figure 17 shows the default configuration login page displayed in the browser. To access the configuration pages used to setup the 619DSRI, you need to log in to the configuration interface by entering a valid user name and a password. You cannot make any changes to the configuration settings until you log in, and the password must be entered for each new web-browser session. When you click on the Log In link, a password dialog similar to the one shown in Figure 18 appears (the dialog shown ® here is the one from Internet Explorer 8). Figure 17. Log-in page of the configuration interface When you log in to 619DSRI for the first time, or if you have not changed the password of the Supervisor account, you can log in under the Supervisor account by using the user name of omni and the default password of dsri (lowercase). If you changed the password, then you should use that password. You cannot change the user name of the Supervisor account. If you are not a supervisor, you can log in under either the Technician account or the Limited User account by using the corresponding user name and password for that account. If you are not sure what account to use, or what the user name and password are for the account, you will need to check with your supervisor as to the correct user name and password to use for the account. Once you have logged in, you will see the configuration user interface with the System Status page displayed in your web browser as discussed in the following sections. Note The password is case sensitive. Figure 18. Connecting to the configuration interface 619DSRI – Product Manual 27 Chapter 4 Supervisor Account If you log in to the configuration interface under the Supervisor account, you will see the System Status page and menus depicted in Figure 19. As a supervisor, you have unlimited access to the configuration settings of the 619DSRI so you can completely configure all aspects of the product. You are responsible for setting up the optional Technician and the Limited User accounts as required. Whilst you are logged in under the Supervisor account, it is recommended that you change the password of the Supervisor account so that non-supervisors cannot gain unrestricted access to the configuration interface. You should also set up the user name and password for both the Technician account and the Limited User account so non-supervisors can log in as required. Figure 19. Using the Configuration interface with the Supervisor account Technician Account When you log in to the configuration interface under the Technician account, only a limited set of menus and configuration pages are displayed, as shown in Figure 20. Under this account, technicians can view the status of the system, such as the System Version Information, the Current Status, the Channel Information, and the Audio Matrix configuration. Additionally, technicians can also access the Radio Diagnostics page to perform troubleshooting and diagnostics of the radio ports on the 619DSRI (refer to Chapter 5, “Diagnostics and Upgrading the Firmware” on page 87). Figure 20. System Status configuration page under the Technician account 28 Using the Configuration Interface Limited User Account When you log in to the configuration interface under the Limited User account, only the System Status page is displayed in your web browser, as shown in Figure 21. Under this account, you can only view the system status and information shown on the System Status page, such as the system version information of the firmware and hardware, the current status, the channel information, the audio matrix configuration, and the digital and analog alarms. Furthermore, you cannot make any changes to the configuration settings or perform any diagnostics and troubleshooting of the product—you must be logged in under the Supervisor or the Technician account to be able to configure the settings or to use the diagnostics tools. Figure 21. System Status configuration settings under the Limited User account Configuration User Interface Figure 22 shows the basic user interface of the configuration interface when logged in under the supervisor account—the page shown here is the Network Configuration page (see “Configuring the TCP/IP Network Settings” on page 36) that is displayed when you select the Network menu. Product name Displays the name of the product Configuration page Displays the name of the configuration page Basic Settings Displays the basic settings for the configuration page Advanced Settings Displays the advanced settings for the configuration page Menu system Shows the configuration and diagnostics menus Configuration status Shows the configuration status and provides buttons to save, undo, and reset the configuration. Figure 22. Using the configuration interface user interface 619DSRI – Product Manual 29 Chapter 4 At the bottom of this page is the Configuration Status area, which shows the status of the configuration and whether you have made any changes to the settings. This area appears on all pages that have configuration settings that you can change, and displays various status messages (see “Configuration Status” on page 30). The left-hand panel of the configuration interface provides the menu system, which shows a menu item for each of the available configuration pages—the items shown in the menu depend on the user account you used when you logged in to the system. The various configuration pages are accessed by clicking on the menu items: selecting a menu item displays the corresponding configuration page on the right-hand side of the interface. Configuration Status On all configuration pages that provide settings you can change, a configuration status area is displayed along the bottom edge of the page. This shows the status of the configuration settings for the current page, such as whether you have made any changes to the configuration, or the configuration has changed but you have not saved the changes you made. Figure 23 shows the Configuration Status area that is displayed when the configuration has not been changed. Configuration status area Shows the configuration status and provides buttons to save, undo, and reset the configuration. Undo button Discards any changes to the configuration Save button Saves the configuration Restart button Restarts the device Status message Shows status messages about the configuration Reset to Defaults button Reloads default settings Figure 23. Configuration status area The Configuration Status area shows the status of the 619DSRI configuration, and provides several buttons to allow you to save or undo any changes you make to the configuration settings. You can also reset the 619DSRI to its default factory settings, and restart the 619DSRI as required. The buttons in the Configuration Status area and the function they perform are described below: • Save allows you to save the changes you made to the settings on the configuration page displayed in the web browser. You must always save the configuration before navigating to another configuration page otherwise the changes will be discarded. • Restart performs a restart of the 619DSRI using configuration settings from flash memory—a restart is required after you save any the changes to the configuration. • Reset to Defaults reloads the configuration with default values for settings on all configuration pages (not just the page displayed in the browser), but does not save the default settings to flash memory. • Undo discards any changes that you made to the settings on the configuration page displayed in the web browser, and reloads the configuration. This affects the settings on all configuration pages; not just the settings on the current page. Tip If you are using a version of a web browser that is not supported, the Configuration Status buttons may not be visible at the bottom of the browser window. This may happen with some older browsers, in which case, you can scroll to the bottom of the page to view the buttons. The area immediately above the buttons is the Status Message area, which is where the various status messages are displayed. Table 3 provides a description of each configuration status message. 30 Using the Configuration Interface Table 3. Configuration status messages Status Description Configuration Unchanged Indicates that the configuration settings on the page have not changed. Configuration has been saved. Restart required to take effect. Indicates that the configuration settings have been saved into flash memory of the 619DSRI, but are not currently used. A restart is required before the new settings will take effect. Data is invalid: IT HAS NOT BEEN SAVED Indicates that one (or more) of the settings entered was invalid and the configuration has not been saved. All configuration values on a page must be valid before any values will be saved. You must identify all incorrect configuration values and correct the errors. The Configuration Status area will show additional information about the incorrect value. Configuration reset to defaults: NOT SAVED Indicates that the ALL configuration settings have been reset to the default values; not just the settings on this page. However, you still need to save the changes to make the changes permanent. Configuration reset to saved values The configuration values on the configuration page have been restored to the values saved in the flash memory. This is the result of clicking the Undo button. Saving the Configuration When you make changes to the settings on a configuration page, or you restore the configuration from a backup file, you must save the changes to the 619DSRI; otherwise, if you navigate to another configuration page, the changes will be discarded. Warning Do not disconnect power while saving the configuration settings or restarting the device; otherwise you may damage the device or corrupt the configuration settings. To save the configuration changes, click the Save button on the current page. After you save the changes, you may need to restart the 619DSRI for the changes to take effect. This depends on what configuration page you are on and which settings you changed. Some settings take effect immediately and do not require a restart. In this case, the status message displayed changes to “Configuration has been saved”, as shown in Figure 24. Figure 24. Saving changes to the configuration settings When you save settings that require you need to restart the 619DSRI, the status message changes to “Configuration has been saved. Restart required to take effect”, as shown in Figure 25. This message indicates that although the configuration has been permanently saved, you now need to restart the 619DSRI for the new settings to be loaded (see “Restarting after Saving the Configuration” below). Figure 25. Saving changes to the configuration settings Important If you change the configuration settings on a page, you must save the changes before leaving that page otherwise the changes will be discarded. 619DSRI – Product Manual 31 Chapter 4 Restarting after Saving the Configuration Once you have saved the existing configuration, you may need to restart the 619DSRI for the changes to take effect (see Figure 25). To restart the 619DSRI, click the Restart button on the page, as shown in Figure 26. Warning Do not disconnect the power to the 619DSRI while it is restarting; otherwise you may damage the device. While the 619DSRI is restarting, the page will show “Restart in Progress”. After about 30 seconds, the 619DSRI should restart and you will be redirected to the log-in page in your web browser. You will then need to log in again if you want to continue configuring the 619DSRI (see “User Accounts and Logging In” on page 26). Figure 26. Restarting after saving the configuration settings After restarting the 619DSRI, it is recommended that you back up the configuration to a file on your computer in case you need to restore the configuration later. For further information on backing up the configuration, refer to “Backing Up and Restoring the Configuration” on page 42. If you can no longer use your web browser to communicate with the 619DSRI after restarting the device, it is most likely that the IP address of your computer is now on a different subnet than the 619DSRI. If this is the case, you’ll need to change it to the same as the 619DSRI device before you can use your web browser. For further information on how to change the IP address of your computer, refer to “Connecting to the Network” on page 19. Note You may need to refresh your web-browser after the 619DSRI has restarted. Resetting the Configuration to Default Settings Sometimes you may want to reset the configuration of the 619DSRI to its factory default settings. This is especially useful when you want to change only a handful of settings as it provides a good starting point for configuring the device. In most cases, the default configuration will do for basic installations with only some changes to a few of the settings. 32 Using the Configuration Interface The default configuration is also useful when you need to troubleshoot a particular problem or the device is not operating as you expected. In this case, you can start with the default settings and carefully make changes as required to determine the cause of any problem. Figure 27 shows the three steps involved in resetting the configuration of the 619DSRI to default settings. The first step in resetting the configuration to default settings is to click the Reset to Defaults button on the page. This resets the in-memory configuration to default settings; however, it does not make the changes permanent. To make the changes permanent after resetting to defaults, you then need to save the default configuration to the 619DSRI by clicking the Save button on the page. The final step in resetting to defaults involves restarting the device by clicking the Restart button on the page. The new settings will then be loaded when the 619DSRI restarts. Reset to Defaults Resetting the configuration to factorydefault settings Save Saving the configuration Restart Restarting the 619DSRI Restart in progress 619DSRI is restarting after resetting to defaults Figure 27. Resetting the configuration to default settings Note, however, that because the 619DSRI is now reset to the factory-default settings, you may not be able to communicate with the device using the same IP address. This is because the 619DSRI has reverted to its default IP address set at the factory. In this case, you may need to temporarily change the network settings of your computer in order to use your web browser to communicate with the device (see Chapter 3, “Connecting to the Network” on page 19 for the further information on how to do this for your operating system). Exiting the Configuration Interface Once you have completed configuring the 619DSRI, it is recommended that you exit from the configuration interface by clicking Exit. This will log you out of the session and load the log-in page; you will need to type your user name and password to access the 619DSRI configuration interface again. For further information about logging in to the web-based configuration interface, refer to “User Accounts and Logging In” on page 26. 619DSRI – Product Manual 33 Chapter 4 Viewing the System Status Use the System Status menu to display the version information for the hardware and firmware used in the 619DSRI, together with its operational status. Figure 28 shows the System Status page. All the values on this page are read-only: you cannot change any of the values on this page. Figure 28. System Status page System Version Information The System Version Information section displays the version information for the firmware that is currently ® loaded in the 619DSRI. The 619DSRI uses two microprocessors: the Freescale™ Coldfire microprocessor performs all of the network and system functions; and a Digital Signal Processor (DSP) performs the audio processing such as encoding and decoding, and tone detection. Also displayed here is the revision of the hardware of the 619DSRI device. Current Status The Current Status section displays status information about the 619DSRI and includes the following: • IP Address shows the current address of the 619DSRI. • System up time or elapsed time since the 619DSRI was last reset (displayed as days, hours, minutes and seconds). • Real Time Clock displays the date and time maintained by the real-time clock onboard the 619DSRI. The time is in 24-hour format and the date is displayed in yyyy/mm/dd format (e.g. 2010/05/31 14:49:42). • System Free Memory shows the unused system memory (KBytes) in the 619DSRI. • DSP Free Memory shows the unused memory (bytes) available for the DSP. 34 Using the Configuration Interface Channel Information The Channel Information section displays the Busy status and Push-To-Talk status of each channel (or port). If a channel is not receiving or transmitting, it is indicated with OFF; otherwise ON. It also displays the selcall last received and the selcall last transmitted; and the DTMF last received and the DTMF last transmitted. Note DTMF is displayed only for legitimate received control tones; tramsitted DTMF control codes will be displayed regardless of whether the codes are in the correct format. Audio Matrix The Audio Matrix section displays the status of the "primary" and "secondary" audio configurations and the optional configurations "a" to "f". If a configuration is active, the CFG line will display a "1" underneath the corresponding configuration. Displaying the Alarm Status The 619DSRI displays the current alarm status on the front-panel LCD and on the System Status page shown in Figure 28. To view the alarm status on the LCD, navigate to the "Display Alarms" item under the "Digital SRI Functions" menu. The Alarms section displays the status of the alarms for both the digital inputs and the analog inputs. The status of an alarm is indicated by one of the status codes shown in Table 4. Table 4. Symbols used to display the alarm status Alarm Status Code Description 0 Input not in alarm condition 1 Input in alarm condition * Input in alarm condition and has been acknowledged For example, when a digital input causes an alarm condition, the corresponding status code for that input will change from '0' to '1'. When the alarm condition is acknowledged (at the remote end), the status code will change to an asterisk ('*') character. As shown in Figure 60, none of the inputs is an alarm condition. 619DSRI – Product Manual 35 Chapter 4 Configuring the TCP/IP Network Settings Use Network page to configure basic network parameters, such as the IP address, network mask, and the gateway address of the 619DSRI. Figure 29 shows the Network Configuration page with default settings. The Network configuration consists of several sections: Basic Settings, Network Settings, and Advanced Settings. Figure 29. Network configuration page Basic Settings The Basic Settings area contains only one setting: the Device network name. This is the name of the 619DSRI device and usually consists of the serial number. This may not contain any whitespace characters. Network Settings The Network Settings area allows you to configure the network settings of the 619DSRI and includes the following: • Automatically obtain IP Address (using DHCP) option is used to allow the 619DSRI to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address, and the domain name server settings will be ignored as appropriate values will be provided by the DHCP server. When this option is selected, the other network settings will be disabled. The default setting is disabled. • Static IP Address is the IPv4 address of the 619DSRI, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The default value is 192.168.0.180 (the default configuration is not to use DHCP). 36 Using the Configuration Interface Note If you want to use the option to Automatically obtain an IP Address (using DHCP), the 619DSRI will attempt to locate a DHCP server on start up. If it cannot find a server, it will either use the static IP address or automatically assign itself an address in the range 169.254.x.x. In this case, the 619DSRI will take a little longer to start up before it times out waiting for a DHCP server. • Netmask is the subnet mask that determines what part of the IPv4 address is used to identify the subnet that the 619DSRI is on. A valid IPv4 subnet mask consists of 32 bits: a sequence of ones (1) followed by a block of zeros (0), expressed in a form consisting of four decimal octets separated by periods (dotdecimal notation). The sequence of ones (1) designates that part as the network prefix (subnet) and the block of zeros (0) designates that part as the host identifier. The default value is 255.255.255.0. • Gateway Address is the IP address of the default network gateway. This would usually be the IP address of the router or network device that provides access to the WAN or internet. A valid IPv4 gateway address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). The default value is 192.168.0.1. Note If you do not specify values for the Static IP Address, Netmask, or Gateway Address, or attempt to set any of these fields to 0.0.0.0, default values will be set instead. Advanced Settings The settings that can be configured under the Advanced Settings on this page are described below: • Enable UPNP selects the Universal Plug and Play (UPNP) feature, which is a networking technology that allows devices to work together with fewer configurations. By enabling UPNP, the 619DSRI will be displayed in the Network Neighborhood on a Microsoft Windows computer. The default setting is Enabled. • Enable network discovery using Bonjour/mDNS protocol selects the Multicast Domain Name System (mDNS) feature, which is a technology that allows devices on a LAN or WAN that supports multicast to provide a domain name instead of an IP Address. mDNS automatically converts the domain name to the corresponding IP Address without the need of a dedicated DNS. By enabling this setting, IPR devices can use names rather than IP addresses on local LANs. However, Microsoft Windows does not support mDNS. The default setting is Enabled. • Domain Name System (DNS) Server 1 is the primary Domain Name Server (DNS). The DNS is how an Internet addresses, such as www.omnitronics.com.au, is converted into a numeric (dot notation) address, like 202.164.22.20. Consult with your ISP or network administrator to determine the correct address. In some cases, the DNS address is the same as the Gateway address. A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of 0.0.0.0 indicates that no DNS is used (this is the default). • Domain Name System (DNS) Server 2 is the backup DNS that is used in the event the primary DNS is not available. A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of 0.0.0.0 indicates that no DNS is used. The default setting is 0.0.0.0 (not used). • Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the 619DSRI through a network management system. The 619DSRI provides basic network statistics through SNMP. If SNMP is not being used, this setting should not be selected. • Syslog host address is the address used for debugging and diagnosing faults with the 619DSRI, which can report debug and error information via a network protocol called SYSLOG. This setting is normally set to the default (not used). A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of 0.0.0.0 indicates that no SYSLOG messages are used. The default is 0.0.0.0 (not used). 619DSRI – Product Manual 37 Chapter 4 Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the 619DSRI to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address, and domain name server settings will be ignored as appropriate values will be provided by the DHCP server.; this is the default setting. If you want to assign a static IP address to the 619DSRI, it is recommended that you allocate an address in the range of 192.168.0.1 to 192.168.0.253 or 10.1.1.1 to 10.1.1.253 as these are especially reserved for private addresses. Note If you want to use the option to Automatically obtain an IP Address (using DHCP), the 619DSRI will attempt to locate a DHCP server on start up. If it cannot find a server, it will either use the static IP address or automatically assign itself an address in the range 169.254.x.x. In this case, the 619DSRI will take an additional 20 seconds to start. When using a DHCP server to automatically allocate an IP address to the 619DSRI, you will not be able to connect to the device since you will not know the IP address allocated by the DHCP server. In this case, you can either use Multicast Addressing or a Local mDNS name, as described below: • Multicast Addressing is a protocol for efficiently sending data to multiple 619DSRI devices at the same time over TCP/IP networks. • Local mDNS name allows you to connect to a 619DSRI device by using a local name address instead of an IP address. Local addressing takes the form of name.local, where name is the Location Name configured on the Network settings page. In Figure 29, the 619DSRI has the Location Name of DSRI52A1680.local. Saving Network Settings Once you make any changes to the Network Settings on the Network Configuration page, you must save the changes to the 619DSRI; otherwise if you navigate to another configuration page, the changes will be discarded. To save the changes, click Save under Configuration Status. When you save the changes, the message displayed under Configuration Status changes to “Configuration has been saved. Restart required to take effect” advising you to restart the 619DSRI so that the new settings can be used. Click Restart to restart the 619DSRI with the new settings. Figure 30 shows the configuration page when a restart is in progress. Figure 30. Restarting the DSRI after saving the configuration settings 38 Using the Configuration Interface Changing the Password Use the Change Password menu to display the Change Password configuration page. This page allows supervisors (i.e. system administrators) to change the password of the account used to access the configuration interface. System administrators will normally log in under the Supervisor account. Once logged in under the Supervisor account, supervisors can enable two additional types of accounts: a technician account and a limited user account. Supervisors can also change the user name and password allocated to each type of account with the exception of the Supervisor account; only the password can be changed. Figure 31 shows the additional accounts under the Technician and Limited user sections of the Advanced Settings. Each account provides different access privileges to the menus, as discussed below. Figure 31. Changing the password of the configuration interface Note Only supervisors can change the password of the Supervisor account. You cannot change the User Name using the web-based Configuration Interface; the User Name remains omni. Supervisor Account To change the password used to access the configuration interface as a supervisor, type the new password you want to use in the Enter supervisor password box, and then retype it in the Confirm password box. Make sure to save the new password by clicking on the Save button; otherwise your changes will be discarded. Important If you make any changes to the account details, you must click on the Save button to save the changes; otherwise the changes you made will be discarded. Once the changes are saved, you must then click on the Restart button to restart the device for the changes to take effect, as indicated by the status message displayed under the Configuration Status area. 619DSRI – Product Manual 39 Chapter 4 Technician Account The technician account provides limited access to the System Status, and Diagnostics menus. Under the Advanced Settings for Technician, the settings are described as follows: • Enable technician user allows users to log in to the configuration interface as a technician by using the Technician account. The default setting is Disabled. • Technician user name is the user name allocated to the Technician account, and is the user name that must be entered in the login dialog when a user wants to log in under the account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default user name is tech. • Technician password is the password allocated to the Technician account, and must be entered into the log into login dialog when a user wants to log in under the Technician account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default is password. To enable the Technician account, simply select Enable technician user; otherwise the account will be disabled. If you want to change the account credentials instead of using the default user name and password, type a user name in the Technician user name box and a password in the Technician password box. Figure 32 shows how to enable and set up the Technician account with the default account credentials. Make sure you save any changes you made by clicking Save; otherwise your changes will not be saved. Figure 32. Enabling the technician account settings Important If you make any changes to the account details, you must click on the Save button to save the changes; otherwise the changes you made will be discarded. Once the changes are saved, you must then click on the Restart button to restart the device for the changes to take effect, as indicated by the status message displayed under the Configuration Status area. 40 Using the Configuration Interface Limited User Account The limited user account provides access to only the System Status and Statistics menus. Under the Advanced Settings for Limited user, the settings are described as follows: • Enable limited user allows users to log in to the configuration interface as a limited user by using the Limited user account. The default setting is Disabled. • Limited user name is the user name allocated to the Limited User account, and is the user name that must be entered in the login dialog when a user wants to log in under the account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default user name is user. • Limited user password is the password allocated to the Limited User account, and must be entered into the login dialog when a user wants to log in under the Limited User account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default is password. To enable the Limited User account, simply select Enable limited user; otherwise the account will be disabled. If you want to change the account credentials instead of using the default user name and password, type a user name in the Limited user name box and a password in the Limited user password box. Figure 33 shows how to enable and set up the Technician account with the default account credentials. Make sure you save any changes you make by clicking Save; otherwise your changes will not be saved. Figure 33. Enabling the limited-user account settings Important If you make any changes to the account details, you must click on the Save button to save the changes; otherwise the changes you made will be discarded. Once the changes are saved, you must then click on the Restart button to restart the device for the changes to take effect, as indicated by the status message displayed under the Configuration Status area. 619DSRI – Product Manual 41 Chapter 4 Backing Up and Restoring the Configuration Use the Save / Restore menu to display the Configuration Save / Restore configuration page as shown in Figure 34. The options on this page allow you to back up and restore [GEM1]the 619DSRI configuration as a file on the hard disk of your computer. It is recommended that the configuration be backed up to a file for safekeeping, in case it needs to be restored later. When the 619DSRI configuration is restored from a configuration file, it needs to be saved to the 619DSRI to make the changes permanent. Figure 34. Saving and restoring the configuration Backing up the Configuration to a File Once you have completed making changes to the configuration of the 619DSRI, it is recommended that you back up the configuration file to your computer for safe-keeping. The backup process involves saving the existing configuration to a file on the hard drive of the computer you are using to access the configuration interface. You will be prompted to select a location on your computer to store the file. The default file name is DSRI_cfg.bin, but you may rename the file if you wish. To back up the configuration 1. Click Backup to display the File Download dialog. 2. Click Save to save the configuration. You will be prompted for a folder and file name in the Save As dialog. 42 Using the Configuration Interface 3. (Optional) If you want to use a different file name than the default (DSRI_cfg.bin), type the file name in the File name box. 4. Click Save to download and save the existing configuration to the specified file. When the download is complete, the Download Complete dialog is displayed. 5. Click Close. Restoring the Configuration from a File You can restore the configuration in the 619DSRI to a previously saved configuration by restoring the configuration from a file on your computer. Restoring the configuration involves loading the configuration from a file on your computer, and saving it to the 619DSRI. Once you have restored the configuration from the file, you then need to restart the 619DSRI for the changes to take effect. Note Restoring the configuration does not save it to the 619DSRI; you must click Save after you have restored the configuration. To restore the configuration 1. Click Browse to locate the file on your computer, or type the full path and file name of the .cfg file in the Select Restore Configuration file box. 2. Click Restore to load and restore the configuration from the file. The Configuration Status changes to Configuration restore complete! (Configuration has not been saved). 3. Click Save to save the configuration to the 619DSRI. This saves the restored configuration to the 619DSRI, but the new configuration will not take effect until you restart the 619DSRI. The Configuration Status changes to "Configuration has been saved. Restart required to take effect". 619DSRI – Product Manual 43 Chapter 4 4. Click Restart to restart the device. Refer to “Restarting after Saving the Configuration” on page 32 for further information. DSRI General Configuration Figure 35 on the following page shows the General page of the SRI Configuration. This page provides several configuration options, such as selcall control, pre-configured software options for overlaying or replacing configurations, and remote control of the ports. You may not be able to display the configuration on one page as shown here; however, you can use the scrollbar to scroll up and down the page as necessary. Site Name The Site Name field allows you to enter a descriptive name for the 619DSRI. You can enter a maximum number of 20 characters including spaces. Selcall Control You can use any port for remote control of the 619DSRI audio matrix using SELCALL or DTMF by entering either the correct SELCALL pre-code (3, 4, 5, or 6 digits) or DTMF command sequence. For a detailed explanation of remote control using Selcall and DTMF, refer to “Remote Control Using Selcall” on page 51, and “Remote Control Using DTMF” in page 54. The procedure below describes how to enable and configure remote control using SELCALL. Each step refers to a specific area on the Selcall Control panel shown in Figure 36. To enable selcall control 1. Select the selcall period from the Selcall Period dropdown list to match the external radio device. 2. Select the selcall scheme from the Selcall Scheme dropdown list to match the external radio device. 3. Under Selcall Control, select Selcall Control Enable. 4. Select the selcall pre-code option from the Number precode digits to match the external radio device. 5. Click Set to accept the pre-code option and to refresh the page. 6. Type a 3, 4, 5, or 6-digit pre-code in the Precode box to match the external radio device. 7. Click Set to accept the pre-code and to refresh the page. 8. Type a control code for each of the Enquiry, Primary, Option A to Option F, and Secondary settings. Note For a 3-digit precode, the number of following control codes defaults to two digits (i.e. the minimum number of selcall tones allowed is five). 9. Click Save to set the parameters in the 619DSRI. 44 Using the Configuration Interface Figure 35. General configuration page showing settings on upper of page 619DSRI – Product Manual 45 Chapter 4 Figure 36. Enabling remote control of the 619DSRI using SELCALL Once you have enabled selcall control, the 619DSRI can be configured to detect a specific number of tones in a selcall command sequence. Each selcall sequence may consist of 5, 6 or 7 tones (n) depending on the number of tones (n-1) that you configure in the precode. Thus, for a 7-tone sequence, the first six tones are assigned to the precode. The precode can be used to uniquely identify and address multiple devices. The last tone in the sequence is the control code, which specifies the function to perform. Note The actual ports connected to the decoder are determined by the Remote Control settings. Software Control Options The 619DSRI device provides pre-configured software options that allow you to apply configuration options when assigning complex audio-routing paths to suit your specific implementation. Under Software Options on the General page shown in Figure 37, you can select one or more pre-configured software options that can be applied to your audio-matrix configuration. Overlaying and Replacing Configurations In normal operation, or overlay mode, the optional configurations (Option A to Option F) are overlaid on the default base configuration (i.e. the primary or the secondary configuration). When overlaying an optional configuration, the mapping changes depending on the mapping of the optional configuration: the resultant mapping is a combination of the optional configuration and the default configuration. The ability of the 619DSRI to overlay optional configurations allows you to configure complex routing paths. However, by selecting Matrix Control Option 2, the matrix operates in replace mode in which each optional configuration will completely overwrite and replace the default configuration. 46 Using the Configuration Interface Figure 37. Selecting software control options on the General page Figure 38 shows the selection of Software Options 1 and 2, and the effect that each option has on the configuration of the matrix when selected either individually or together. Figure 38. Matrix configuration when selecting software option 1 and 2 619DSRI – Product Manual 47 Chapter 4 The function of each digital opto-input (with Software Option 1 selected) is listed in Table 5 on page 48. A description of each software option is listed in Table 6 on page 48. Table 5. Function of inputs when using Software Option 1 Input Function None The Primary configuration is the default configuration. 1 Option A 2 Option B 3 Option C 4 Option D 5 Option E 6 Option F Table 6. Software options Software Option Description Option 1 When this option is selected, any digital opto input that is not used for Digital CTCSS (set on the Input page) can be used to invoke one of the optional configurations (Option A to Option F); i.e. Digital CTCSS 1 = Option A, Digital CTCSS 2 = Option B, and so on. Whilst the input is active, the relevant configuration replaces the current configuration. When the input deactivates, the default configuration (Primary or Secondary) is restored. By default, this feature causes the first active input to be accepted and its corresponding optional configuration to be applied , replacing the current configuration. Other active inputs are ignored as Input 1 has the highest priority. For example, if Digital CTCSS 1 is activated after Digital CTCSS 2, Option A will override Option B ; and if Digital CTCSS 6 is activated after Digital CTCSS 5, Option E will remain on. This option can be used in conjunction with Option 2 to implement multiple overlays that only modify the current configuration (refer to the matrix diagram below). Option 2 This option can be used independently or in conjunction with Option 1 (refer to the matrix diagram below). When used independently, DTMF and SELCALL commands will cause the relevant optional configuration to replace the current configuration, thus destroying the current configuration. Otherwise, whilst in normal operation, the configuration will be to be overlaid with one or more of the optional configurations. Option 3 The CTCSS tone will control the PTT outputs and steer the audio according to the Matrix Configuration, without reference to the Busy signal activating. This behaves similarly to the in-band keying function but with CTCSS. Note: This software option is applicable to only analog CTCSS and cannot be used if the Fast Output option is selected (see “Fast Output” on page 64 ). Option 4 In-band Tones Input Validation . Applies a 1 second input validation on In-band tones. This is useful in situations when a tone is used to signify an emergency situation and therefore false triggering must be minimised. Option 5 Alternate simplified heartbeat function. All ports share a common heartbeat timer that is updated whenever any PTT is activated. Option 6 When this option is selected, only the port that receives the acknowledging code will have its reporting code cleared; and if more than one port is enabled, the other enabled ports will still have the corresponding reporting code sent out until it is either acknowledged or the alarm condition is cleared. When this option is not selected, when receiving the acknowledging code, the 619DSRI will clear the associated reporting code so that it will not be sent out on all enabled ports (set by the Alarm Selcall Port Enable). 48 Using the Configuration Interface Note The 619DSRI normally operates in overlay mode in which optional configurations (Option A to Option F) are overlaid on the current configuration. The overlay of configurations allows complex routing paths to be configured. However, using Software Option 1, the unit will operate in replace mode in which each optional configuration will overwriteand replace the existing configuration. Busy Tail Delay The Busy Tail Delay period is the length of time that the device should wait before a reply is sent, after receiving a data packet. The value can be changed in increments of 10ms from 30 to 1500ms. This setting is useful when receiving Selcall/DTMF and sending Selcall/DTMF echo or tone replies. PTT Lead-in The PTT Lead-in delay period is the length of time that the device should wait after activating a PTT, before transmitting a data packet. The value can be changed in increments of 10ms from 30 to 1500ms. This setting is useful when receiving Selcall/DTMF and sending Selcall/DTMF echo or tone replies. Tone Reply The option available for tone reply (acknowledgement) is a single tone of 700Hz for 200ms. The 619DSRI will always reply to a DTMF command or Selcall. The tone reply is an audible tone (1 or 2 beeps). Note If the output for the port is not set to No Tone, the reply tone will be mixed with either the CTCSS or In-band tone. DTMF/Selcall Echo The option available for DTMF/SECLALL Echo (acknowledgement) is an echo of the SELCALL or DTMF sequence that was originally received by the unit. The 619DSRI will always reply to a SELCALL or DTMF command. The reply of the SELCALL is the sequence received by the port enabled for Selcall. The reply of the DTMF is the sequence of DTMF tones received by the port enabled for DTMF. Remote Control You can dynamically change the Busy to PTT Control Matrix (configured on the DSRI Configuration Matrix page) to a pre-configured matrix over the air by remote control using SELCALL (Selective Calling) or DTMF on selected ports. You can also change the configuration settings remotely by enabling remote control on one or more ports (configured on the DSRI Configuration General page). On the DSRI Configuration General page shown in Figure 39, the Remote Control section determines the radio ports that can accept inbound remote commands (DTMF or SELCALL). 619DSRI – Product Manual 49 Chapter 4 Figure 39. Remote control and modem settings on the DSRI Configuration General page The port(s) that will accept and decode remote commands (SELCALL or DTMF) or allow the legacy V.23 modem operation can be selected as shown in Figure 39. Selecting a port to receive remote commands will ensure that a command received on that port will not be affected by other traffic received on that port. The legacy V.23 DSP modem functionality allowed up to three modem ports to be enabled, after which the other ports were automatically disabled, as shown in Figure 40. Figure 40. Enabling V.23 DSP Modem ports Note To decode SELCALL or DTMF commands on a port, the port must be enabled for remote control. 50 Using the Configuration Interface Remote Control Using Selcall The Busy to PTT Control Matrix can be dynamically changed via a remote SELCALL sequence, such as a SELCALL transmission from a mobile radio. To allow remote control using SELCALL, you need to enable SELCALL control by selecting the Selcall Control Enable option under Selcall Control, as shown in Figure 41, and you need to select the ports under Remote Control on which you want to allow remote control operation. Figure 41. Enabling remote control using SELCALL Selcall Commands for 4 to 6-Digit Precodes Once you have enabled selcall control and selected the ports to use, the 619DSRI can be configured to detect a specific number of tones in a selcall command sequence. Each selcall command may consist of 5, 6 or 7 tones (n) depending on the number of tones (n-1) you configure in the precode. Thus, for a 4-digit precode, the valid commands will range from 0000M to 9999M, where M is the function from 0 to 8. Table 7 shows the available functions that you can use to invoke preset configurations. The last tone in the sequence specifies the function (M), i.e. 1234(M) for our particular pre-code configuration. A function tone of 0 causes the 619DSRI to reply with an audible tone. The other functions will force the 619DSRI to directly invoke one of the preset optional configurations by overlaying it (if Option 2 is not enabled as previously described). Hence, a selcall sequence of XXXX1 would invoke the Primary configuration, XXXX2 would invoke Option A, and XXXX8 would invoke the Secondary configuration, where XXXX is the precode. For example, using a precode of 1234, to invoke the secondary configuration, you would send 12348 (the unit will reply with two audible beeps); and to invoke the primary configuration on the same device, you would send 12341 (the unit will reply with a single audible beep). Note If Software Control Option 2 is enabled, the unit replies with two beeps regardless of whether querying or Invoking a configuration. 619DSRI – Product Manual 51 Chapter 4 Table 7. Commands with 4 to 6-digit precodes used to invoke preset configurations Description Function (M) Response Tone(s) Set Primary as the default 1 1 beep Invoke Option A 2 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12342 Invoke Option B 3 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12343 Invoke Option C 4 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12344 Invoke Option D 5 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12345 Invoke Option E 6 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12346 Invoke Option F 7 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12347 Set Secondary as the default 8 2 beeps Selcall Example Selcall Commands for 3-Digit Precode The 3-digit pre-code is a special case of 5-tone sequence. Each SELCALL command must consist of 5 tones with a 3-digit precode. The last two tones consist of a function tone (M) followed by a qualifier tone (K). Thus, for a 3-digit precode, the valid commands to invoke a configuration will range from 000MK to 999MK, where M is the function of 0, and K is the function qualifier from 0 to 8. Table 8 shows the commands that you can use to invoke preset configurations. The last two digits are preconfigured to specify the command. A function qualifier tone of 0 causes the 619DSRI to reply with an audible tone. The other commands will force the 619DSRI to directly invoke one of the preset configurations as default. Table 8. Commands with 3-digit precode used to invoke preset configurations Description Function (M) Qualifier (K) Response Tone(s) Set Primary as the default 0 1 1 beep Invoke Option A 0 2 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12302 Invoke Option B 0 3 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12303 Invoke Option C 0 4 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12304 Invoke Option D 0 5 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12305 Invoke Option E 0 6 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12306 Invoke Option F 0 7 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 12307 Set Secondary as the default 0 8 2 beeps 52 Using the Configuration Interface Selcall Example Note If Software Control Option 2 is enabled, the unit replies with two beeps regardless of whether querying or Invoking a configuration Hence, a selcall sequence of XXX01 would invoke the Primary configuration, XXX02 would invoke Option A, and XXX08 would invoke the Secondary configuration, where XXX is the precode. For example, using a precode of 123, to invoke the secondary configuration, you would send 12308 (the unit will respond with two audible beeps); and to restore the primary configuration on the same device, you would send 12301 (the unit will respond with a single audible beep). Checking the State of a Relay (3-Digit Precode) To check the state of a relay, precede the function qualifier (K) with function (M) of 4. That is, to check the state of relay 1, send XXX41; and to check the state of relay 2, send XXX42. If the specified relay is active, the 619DSRI will respond with a single-beep acknowledgment; if not active, the 619DSRI will respond with a twobeep acknowledgement. Table 9 lists the commands to check the state of a relay. Table 9. Selcall commands to check the state of relays Description Function (M) Qualifier (K) Response Tone(s) Selcall Example Check the state of relay 1 4 1 1 beep = ON; 2 beeps = OFF 12341 Check the state of relay 2 4 2 1 beep = ON; 2 beeps = OFF 12342 Note To use this function, the relays must be set to Remote on the Output Control page under Remote Control section; otherwise, you will hear two beeps. Individual Relay Control (3-Digit Precode) Both relays can be turned on or off individually by sending the appropriate 5-tone selcall command. To activate a relay, precede the function qualifier (K) with the function (M) of 5. That is, to activate relay 1, you would send XXX51; and for relay 2, you would send XXX52, where XXX is the precode. To reset an active relay, you would send the same command (i.e. a toggle action). Table 10 lists the available commands to control the relays. Note To use this function, the relays must be set to Remote on the Output Control page under Remote Control section; otherwise, you will hear two beeps. Furthermore, relay control is only available when using a 3-digit precode with a 5-tone sequence. Table 10. Selcall commands to control relays Description Function (M) Qualifier (K) Response Tone(s) Selcall Example Activate (or deactivate) relay 1 5 1 1 beep = ON; 2 beeps = OFF 12351 Activate (or deactivate) relay 2 5 2 1 beep = ON; 2 beeps = OFF 12352 Note If Software Control Option 2 is enabled, the unit replies with two beeps regardless of whether querying or changing the state of a relay. 619DSRI – Product Manual 53 Chapter 4 Remote Control Using DTMF The 619DSRI device can be controlled via remote control with DTMF, such as a mobile transmission sending a DTMF sequence using a DTMF keypad. Two main functions are supported: ● Changing the audio configuration ● Controlling individual relays To allow remote control using DTMF, you need to select the ports you want to use for remote control operation. Similar to selecting ports for remote control using SELCALL, you select the ports under the Remote Control section; any ports that you select will enable remote control using DTMF. Note The actual ports connected to the DTMF decoder are determined by the ports that you select under the Remote Control settings. The format for any DTMF command is: #NNN*MK where NNN is the Device Identity (i.e. 001, 002, or 003 etc.); M is the Function; and K is the Function Qualifier. Changing the Configuration The default configuration can be changed to Primary or Secondary regardless of whether configuration Software Option 2 is active (refer to “Software Control Options” on page 46 for further information about software options). The commands shown in Table 11 will overwrite the current configuration. Table 11. DTMF commands to change the configuration Description Function (M) Qualifier (K) Response Tone (DTMF Echo = last 3 digits) Set Primary as the default 1 1 1 beep Set Secondary as the default 1 2 2 beeps For example, to invoke the secondary configuration on a device with a device ID of 1, you would send #001*12; and to restore the primary configuration on the same device, you would send #001*11. Table 11 shows the response from the 619DSRI when the DTMF/Selcall Echo is not enabled: the 619DSRI will respond with either a single- or double-beep. In the case when the DTMF/Selcall Echo is enabled, the 619DSRI will respond by echoing the last three DTMF tones sent (i.e. *11). Optional configurations can be invoked according to the functions and function qualifiers listed in Table 12. Table 12. Invoking optional configurations Description Function (M) Qualifier (K) Response Tone (DTMF Echo = last 3 digits) Invoke Option A 3 1 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Invoke Option B 3 2 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Invoke Option C 3 3 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Invoke Option D 3 4 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Invoke Option E 3 5 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Invoke Option F 3 6 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 54 Using the Configuration Interface Note If Software Control Option 2 is enabled, the unit replies with two beeps regardless of whether querying or Invoking a configuration. The examples in Listing 1 show how to send commands to invoke the optional configurations, Option A to Option F. When an optional configuration is activated, it will remain active until it is reset manually (“001” assumes a device ID of 1). Option A: #001*31 Option B: #001*32 Option C: #001*33 Option D: #001*34 Option E: #001*35 Option F: #001*36 Listing 1. DTMF commands to invoke optional configurations Toggle Action (Overlay Mode Only) In standard overlay mode, the optional configurations can be toggled on and off. If one of the optional configurations Option A to Option F is already active, sending a function qualifier (K) preceded by the function code (M) of 3 (e.g. #001*31) will clear that option; otherwise, it will set that option. That is, if option A is the active configuration, sending #001*31 will clear that configuration. Querying a Configuration To query the base configuration, precede the function qualifier (K) with the function code (M) of 0 (i.e. send #001*00). If the base configuration is active, the 619DSRI will respond with a single-beep acknowledgment. If the base configuration is not active or if the Secondary configuration is active, the 619DSRI will respond with a two-beep acknowledgement. To query an optional configuration, precede the function qualifier (K) with the function code (M) of 2. That is, send #001*21 to query the Option A configuration; and send #001*22 to query the Option B configuration, and so on. Table 13 lists the commands and responses for querying a configuration. Table 13. Querying a configuration using DTMF Description Function (M) Quailifier (K) Response Tone (DTMF Echo = last 3 digits) Query the base setting 0 0 1 beep = Primary Active; 2 beeps = Secondary Active (Overlay mode) 1 beep = Primary Active; 2 beeps = Secondary Active (Replace mode) Query Option A 2 1 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Query Option B 2 2 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Query Option C 2 3 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Query Option D 2 4 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Query Option E 2 5 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) Query Option F 2 6 1 beep = ON; 2 beeps = OFF (Overlay mode) 2 beeps = ON/OFF (Replace mode) 619DSRI – Product Manual 55 Chapter 4 Note If Software Control Option 2 is enabled, the unit replies with two beeps regardless of whether querying or Invoking a configuration. Individual Relay Control (Toggle Action) Both relays can be individually turned on and off by remote control DTMF commands. Note To use this function, the relays must be set to Remote on the Output Control page under Remote Control section; otherwise, you will hear two beeps. Table 14 lists the commands and responses to toggle the state of the relays. To activate a relay, precede the function qualifier (K) with the function code (M) of 5. Table 14. Individual relay control Description Function (M) Qualifier (K) Response Tone (DTMF Echo = last 3 digits) Activate Relay 1 5 1 1 beep = ON Deactivate Relay 1 5 1 2 beeps = OFF Activate Relay 2 5 2 1 beep = ON Deactivate Relay 2 5 2 2 beeps = OFF Hence, to activate relay 1, you would send #001*51, and to activate relay 2, you would send #001*52. To reset an active relay, you would send the same command (i.e. a toggle action). Note If Software Option Control 2 is enabled, the unit replies with two beeps regardless of whether querying or changing the state of a relay. Checking the State of a Relay You can check the state of a relay by sending the appropriate remote control DTMF command. Note To use this function, the relays must be set to Remote on the Output Control page under Remote Control section; otherwise, you will hear two beeps. Table 15 lists the commands to check the state of the relays. To check the state of a relay, precede the function qualifier (K) with the function code (M) of 4. For example, to check the state of relay 1, you would send #001*41; and to check the state of relay 2, you would send #001*42. If the relay is active, the 619DSRI will respond with a single-beep acknowledgment. If the relay is no not active, the 619DSRI will respond with a twobeep acknowledgment. Table 15. Checking the state of a relay Description Function (M) Qualifier (K) Response Tone (DTMF Echo = last 3 digits) Check the state of Relay 1 4 1 1 beep = ON; 2 beeps = OFF Check the state of Relay 2 4 2 1 beep = ON; 2 beeps = OFF 56 Using the Configuration Interface DSRI Matrix Configuration The DSRI Matrix page shown in Figure 42 allows you to configure eight pre-defined input-to-output configurations. The 619DSRI uses the configurations to map Busy inputs to PTT outputs. Each configuration specifies how incoming COS (Carrier Operated Squelch) activated audio is routed to outgoing PTT activated audio. Each audio source can be mapped to either one or more destinations, or need not be mapped at all. Figure 42. SRI matrix configuration page Base Configurations and the Default Configuration The 619DSRI provides two base configurations known as the primary configuration and the secondary configuration. When power is applied to the 619DSRI, the primary configuration is always selected as the default configuration. The default configuration is also the configuration that is used whenever the port input functions are disabled or set to None (see “Port Functions” on page 63). The default configuration can be changed to the secondary configuration through a remote DTMF or selcall command; this allows the audio paths to be changed dynamically according to the Secondary configuration using the System Split feature (see “System Split Timeout” on page 82). Since the configuration can be dynamically changed, by several methods, the default configuration plays an important role in the operation of the 619DSRI. Optional Configurations Each of the base configurations can be modified at any time by configuring one or more optional configurations. Each of these optional configurations can assign new input-to-output mappings or remove existing input-tooutput mappings. Each optional configuration can also be removed by clearing it. Thus, the original default base configuration (whether primary or secondary) can always be restored. 619DSRI – Product Manual 57 Chapter 4 Configuring the Busy to PTT Control Matrix The Busy to PTT Control Matrix consists of an 8 by 8 matrix (see Figure 42) of Busy Inputs (Port 1 to Port 8) that map directly to Push-To-Talk Outputs (Port 1 to Port 8). A row in the matrix corresponds to one of the Busy Input ports; and a column in the matrix corresponds to one of the Push-To-Talk Output ports. Using the Busy to PTT Control Matrix, you configure the way audio is routed in the system by changing the mapping of inputs to outputs for one or more of the pre-defined configurations. The DSRI Matrix page provides six optional configurations that you can use to change the default mapping of inputs to outputs. The available optional configurations are: Option A, Option B, Option C, Option D, Option E, and Option F. Each configuration is independent of the others, but depending on how your system is configured, the optional configurations can interact with the Primary and Secondary configurations to build complex routing maps. The optional configurations can either overlay or replace the default configuration and change the mapping of the inputs to outputs. For further information about overlaying and replacing configurations, refer to “Overlaying and Replacing Configurations” on page46. Selecting a Configuration You can display the matrix for a particular configuration by selecting it from the list of pre-defined configurations. You select a configuration from the Assign Configuration dropdown list, and then click on the Select Configuration button. When you select a configuration, the mapping of inputs to outputs appears in the matrix. The matrix uses several different icons to indicate the type of mapping assigned to a port. The icons have different meanings depending on whether you are configuring a base configuration (i.e. Primary or Secondary) or one of the optional configurations. Table 16 describes the different types of matrix icons that appear in the Busy to PTT Control Matrix. Table 16. Types of icons displayed in the Busy to PTT Control Matrix Matrix icon Description In both the Primary and Secondary configurations, this icon indicates that the audio path from the input is not mapped to the output. In the optional configurations Option A to Option F, this icon indicates that the mapping of the audio path from the input to the output is not changed by the optional configuration. In both the Primary and Secondary configurations and the optional configurations Option A to Option F, this icon Indicates that the audio path from the input is mapped to the output. In the optional configurations Option A to Option F, this icon Indicates that the audio path from the input to the output in both the Primary and Secondary configurations will be “blocked” by one of the optional configurations. Blocking can be applied only by an optional configuration, and takes effect only when the optional configuration is activated. Changing the Configuration Using the matrix, you can change the port mapping of the selected configuration by selecting or deselecting ports in the Busy to PTT Control Matrix (i.e. by clicking on the boxes in the matrix). Ports corresponding to the Busy Inputs can be mapped to any of the ports associated with the Push-To-Talk Outputs. Each time you click on a box, the appearance of the box changes to one of the icons shown in Table 16. The icons that appear in the matrix depend of whether you are changing the default configuration (i.e. the Primary or the Secondary configuration) or one of the optional configurations (i.e. Option A to Option F). Click Port mapped Port not mapped 58 Using the Configuration Interface When you make changes to either the Primary or the Secondary configuration, you map an input to an output by selecting the corresponding box (icon changes to the “mapped” icon ), or unmap the input from the output by deselecting the box (icon changes to the “unmapped” icon ). Click Click Click Port not mapped Port mapped Port unchanged Similarly, when you make changes to one of the optional configurations, you map an input to an output, by selecting the corresponding box (icon changes to the “mapped” icon ), or you can unmap an input from an output by deselecting the box (this time, however, the icon changes to the “unmapped” icon ). This icon indicates that the mapping of the input audio to the output in the underlying default configuration (if the default mapping exists) will be effectively “blocked” or unmapped by the optional configuration, but only when the optional configuration is invoked. If you do not want the optional configuration to unmap any existing default mapping for a particular input to output, you can “unblock” that mapping by clicking on the box again (this time, however, the icon changes to the “unchanged” icon indicating that the optional configuration will not affect the default configuration when it is invoked). You can also clear all the mappings for the selected configuration by clicking on the Clear All button. This makes it easy to build a configuration from scratch using a blank matrix as a starting point. Note The Clear All button clears the mappings for only the selected configuration: it does not affect the other configurations. Clearing the configuration does not automatically save the configuration so you must click on the Save button if you want to save the configuration. Overlaying an Optional Configuration You can overlay one or more of the optional configurations (Option A to Option F) over the default configuration (Primary or Secondary) to dynamically change the routing matrix. In an overlaid matrix, the mapping is a combination of the base configuration and the optional configuration overlaid on top of the base configuration. The optional configuration determines the mapping that is applied. Figure 43 shows an example of the mapping for the Primary configuration in which the following mapping is assigned: ● Input port 1 maps to output ports 1 and 2 ● Input port 2 maps to output ports 3 and 4 ● Input port 3 maps to output ports 5 and 6 ● Input port 4 maps to output ports 7 and 8 The mapping above is the default mapping of input ports to output ports as defined in the Primary configuration. Figure 43. Mapping of the default Primary configuration 619DSRI – Product Manual 59 Chapter 4 However, you can change this default mapping by overlaying an optional configuration. Figure 44 shows the effective mapping that will result when the optional configuration Option A is overlaid on top of the Primary configuration. In this configuration, Option A completely removes the default mapping for ports 1 to 4 and assigns new mapping for ports 1 and 7. Busy Input Port 1 mapped to Push-To-Talk Output Port 7 in overlaid configuration Option A configuration overlaid on Primary configuration Busy Input Ports 1 to 4 unmapped from Push-To-Talk Output Ports 1 to 8 in overlaid configuration Busy Input Port 7 mapped to Push-ToTalk Output Port 8 in overlaid configuration Figure 44. Effective mapping when Option A is overlaid on the Primary configuration Multiple optional configurations can be overlaid over the top of the default configuration (Primary or Secondary, whichever is in effect). When this occurs, the resulting active matrix is the combination of the default configuration and all of the optional configurations that have been invoked. When a change of configuration occurs, the resulting active matrix is determined by firstly logically OR-ing all the active configurations that specify mapping from an input to an output. Once that is done, any unmapped inputs are applied. Therefore, the unmapped inputs take precedence. Saving the Configuration When you have finished making changes to the mapping, you must save the configuration by clicking on the Save button; otherwise, the configuration will not be saved. You can also save the changes you made to the configuration by selecting another configuration from the list and clicking on the Select Configuration button: this automatically saves the current configuration before displaying the selected configuration. Caution When you click on the Select Configuration button, the mapping of inputs to outputs for the current configuration is automatically saved before the mapping for the newly selected configuration appears in the matrix. You should ensure the mapping is correct before selecting another configuration. Dynamically Changing the Matrix Once you have set up the optional configurations, the audio control matrix can be dynamically changed through any one of the following change events: ● Activation of a digital input ● Detection of a CTCSS or In-band tone ● Activation of the COS input ● Reception of a remote DTMF or SELCALL operator command Directly Invoked Options Whilst the optional configurations are designed to modify the default configuration through an overlaying process, each one can also be directly invoked, hence destroying the previous configuration. This allows the 60 Using the Configuration Interface 619DSRI to be configured with an additional six configurations. This can be done based on Matrix Control Option 1 or Matrix Control Option 2, in which Selcall/DTMF can be used or Digital CTCSS inputs can be used. Exceeding the DSP Load Threshold In the unlikely event that you exceed the audio-processing specifications of the device (i.e. 80% of the audioprocessing capacity), the audio will sound distorted and a warning message will appear on all of the DSRI Configuration pages, as shown in Figure 45. Figure 45. Warning message appears when audio processing requirements are unrealistic Under normal operation and configuration, you should never exceed the audio-processing capability of the 619DSRI device. This situation is usually a result of excessive configuration well beyond the typical application of the 619DSRI. For example, you will eventually cause the audio to sound distorted and the warning message to appear if you configure an “abnormal” configuration comprising the following steps: • Enable all ports for remote control using selcall • Configure the Primary configuration to map all eight inputs to all eight outputs • Configure all input ports for in-band detection (frequency selection not important) • Configure all output ports to generate an in-band tone at a different frequency than the tone specified for the input of the port If the audio sounds distorted or you see this warning message, it is recommended that you switch off all unused DSRI Configuration settings, which are located on the various DSRI Configuration pages. Once the audio processing returns within the normal levels (i.e. below 70% of the audio-processing capacity), the audio should sound clear again, and the warning message will disappear from all of the DSRI Configuration pages. Note If the audio still sounds distorted once the message disappears, it is recommended that you restart the 619DSRI device. 619DSRI – Product Manual 61 Chapter 4 DSRI Input Control Configuration The Input Control page shown in Figure 46 allows you to configure the operation of each of the eight input ports on the 619DSRI. You can select from several options to determine what happens when a port receives an input qualifier signal and how this affects the audio switching. Figure 46. SRI Input Control configuration page The Input Control configuration provides two fundamental functions: ● Determining whether an input needs to be qualified ● Specifying which matrix configuration will be dynamically switched These fundamental functions are discussed in the following sections. Input Qualification Each port can be configured to accept incoming audio signals with or without qualification; when a signal is accepted, it is then passed on to the receiver mixing circuit and routed according to the audio switching matrix. Normally, when the Busy (COS) input is active on a port, the audio signal received on that port is accepted without qualification, and is then switched according to the Busy to PTT Control Matrix. This is the default functionality that occurs when No Functions or Busy Switching is configured for the port, as shown in Figure 46. 62 Using the Configuration Interface However, by selecting one of the Rx Signaling options for the port function, an audio signal will be accepted only if the signal is qualified according to the port function option selected, such as qualification with a CTCSS tone, an in-band keying tone, or a digital CTCSS input. The Busy Switching option does not qualify the input signal; the signal is considered to be qualified. Note The presence of Busy is only required when the input is set to detect an Audio CTCSS Frequency (and CTCSS controls PTT outputs is not enabled); the Digital CTCSS and In-band tone signal is considered to be qualified without the presence of Busy. Dynamic Switching Each input signal that is qualified using one of the Rx Signaling options can be configured to cause a temporary change in the default audio switching configuration; this provides you with the ability to change the routing of the audio through a radio network. You can dynamically change the default audio configuration by selecting either the Input Busy Switching option, or one of the Rx Signaling options such as Digital CTCSS, In-band Keying Tone, or Audio CTCSS Signaling. On reception of a qualified signal, the 619DSRI will overlay the optional configuration (Option A to Option F) that is selected for that port receiving the signal. To qualify an input signal without performing any switching function, select No Change from the dropdown list for the option and the Primary matrix will be in effect. Port Functions Each port can be independently configured to use one of the port function options by selecting an option under the Input Control Mode for the port. The available port-function options are: “No Function”, “Busy Switching”, and “Receive Signaling”. Figure 47 shows an example in which port 1 is configured to use the Receive Signaling option with in band tone detection. Figure 47. Example of port function options 619DSRI – Product Manual 63 Chapter 4 No Function If you select the No Function option for a port, an audio signal received on that port is accepted and acted upon with a Busy qualification. You cannot perform any dynamic audio switching using this option; the action taken depends on the Primary switching configuration. Busy Switching With the Busy Switching option selected for a port, on detection of the busy (COS) input, the configuration specified in the associated drop-down list will be used to switch the audio. If you select No Change, the audio switching will not be changed and Primary matrix will be active. However, if you select one of the options Option A to Option F, the audio will be switched accordingly and overlaid with the Primary configuration. This allows an incoming signal to be automatically routed through to the outputs. This feature is useful when combined with the FIFS option. Receive Signaling The Rx Signaling group of options provides input qualification and dynamic switching when using sub-audible CTCSS or in-band keying tones. When you select one of the Rx Signaling options, once an input signal is accepted, a different audio configuration may be used to route the audio. If you select No Change, the audio switching will not be changed and the Primary matrix will be active. However, if you select one of the options Option A to Option F, the audio will be switched according to the configuration set up for that option and overlaid with the Primary matrix, and the port PTT Outputs specified in that configuration will activate. The options available under RX Signaling include the following: • Digital CTCSS option ensures that an incoming signal is acted upon only when the relevant digital input is active on the port. Each port is associated with one of the eight digital (opto) inputs. Digital input #1 is the CTCSS input for Port 1, and Digital Input #2 is the CTCSS input for Port 2 etc. • In-band Tone option ensures that a signal is received and acted upon only when the specified in-band tone is detected on the port. Note Only one in-band frequency can be used at any one time. • Audio CTCSS option uses the internal CTCSS decoder to detect any frequency within the standard CTCSS range. From the frequency drop-down lists for f1 and f2, select either one-tone or two-tone frequencies. On reception of a tone (or tones) the configuration(s) specified in the drop-down list(s) of that port, will be invoked. If one tone only is to be detected, set the configuration and tone frequency in the f1 lists and set the frequency of the second tone to NONE in the f2 list. Fast Output The Fast Output option operates hand-in-hand for detection of sub-audible CTCSS. When the Fast Output option is selected, the port in question will immediately invoke the specified configuration, thus activating the PTT outputs. If however, the CTCSS tone is not detected within one second, the output(s) will revert to the off state. You can specify only one frequency at a time in this mode. With the Fast Output option unselected, the input will be taken only when the specified tone(s) are detected. First In First Served (FIFS) The FIFS option allows you to create a group of ports that are priority based. This is useful in situations when multiple inputs may cause conflicting changes to the matrix. With FIFS, all ports that are configured in this mode are treated with respect to each other. Thus, when a FIFS input is detected, it can only cause a change to the configuration if it is the first input in that group. Once an input is accepted, it becomes the controlling FIFS input, and therefore it controls the audio matrix. Any other FIFS inputs that are received after will be locked out from changing the configuration. However, these 64 Using the Configuration Interface other inputs can still be used by the system as part of the audio mixing process. After the controlling FIFS input deactivates, the configuration is not necessarily immediately restored to its default setting. Instead, the 619DSRI will wait until all FIFS inputs are no longer active before restoring the configuration to the default setting. Example of Input Control with Optional Configurations and FIFS In this example, both the primary configuration and the secondary configuration are cleared so that no ports are mapped in either configuration. Instead, port mapping is achieved by setting up several optional configurations to control how the inputs are mapped to the outputs (see Figure 48, Figure 49, and Figure 50). The optional configurations used are Option A, Option B, and Option C, and are configured as follows: ● Option A: Input port 1 is linked to output port 4; input ports 2 and 3 are linked to output port 5 ● Option B: Input port 2 is linked to output port 4; input ports 1 and 3 are linked to output port 5 ● Option C: Input port 3 is linked to output port 4; input ports 1 and 2 are linked to output port 5 Figure 48. Example configuration for Option A Figure 49. Example configuration for Option B 619DSRI – Product Manual 65 Chapter 4 Figure 50. Example configuration for Option C Each port has a port function configured on the Input Control page, and each has the Enable First In First Served (FIFS) option selected. This option causes each configured input to be acted on in the order in which it is detected. Selecting the FIFS option with each of the above the configurations means that the following audio routing will occur when each of the inputs is detected: • If Port1 is detected first, that input goes to output port 4 and inputs 2 and 3 go to output port 5. • If Port2 is detected first, that input goes to output port 4 and inputs 1 and 3 go to output port 5. • If Port3 is detected first, that input goes to output port 4 and inputs 1 and 2 go to output port 5. Figure 51, Figure 52, and Figure 53 show the Input Control page for each port with the above port functions applied. Figure 51.

This mechanism is provided by the software options on the General page. For further information about the available software options, refer to “Software Control Options“ on page 46. 619DSRI – Product Manual 67 Chapter 4 VOX Control The 619DSRI device can be configured to generate an internal busy when detecting a voice input on a port. This can be done on each port and works through a combination of hardware and software. Detection is based on the signal level of an analog input exceeding the value of the VOX Threshold setting. This is configurable in steps of 0.315Vp-p up to a maximum level of 2.5Vp-p. This value must be adjusted with reference to the nominal receive signal level. To prevent false triggering, a software attack time of approximately 5ms is incorporated into the VOX operation; this provides a validation function on the input signal. After VOX is detected and validated, the 619DSRI will hold the internal busy state active whilst voice activity continues to be detected or until the period set by the VOX Hang Period elapses. The hang time is configurable in 100ms steps within the range 0.2 to 5.0 seconds. Each port can be configured to use VOX control by selecting the appropriate Enable VOX Control option. Figure 54 shows the SRI VOX Control page. Figure 54. Enabling VOX operation on selected ports 68 Using the Configuration Interface DSRI Output Configuration The Output Control page allows you to configure the outputs, as shown in Figure 55. Figure 55. Output Control configuration page No Tone When the No Tone option is selected as shown in Figure 56, the 619DSRI will pass through a CTCSS or in-band tone and mix it with an out-going audio signal only. Fixed CTCSS Outputs When a PTT Output is activated, a specific CTCSS tone can be generated on the output port. The CTCSS button allows the user to specify one of 47 frequencies to be output whenever the PTT for that port is active. Figure 56. Output control modes for Port 1 In-band Tones When a PTT Output is activated, a specific In-band tone (2600Hz, 2970Hz etc) can be generated on the output port. The In-band button allows the user to specify one of 5 frequencies to be output whenever the PTT for that port is active. 619DSRI – Product Manual 69 Chapter 4 Follow Input This mode allows the output circuit to mix a sub-audible CTCSS or an in-band tone with the outgoing audio signal. The actual signal that is generated depends on the input condition that caused the output PTT to activate. For example, if an in-band qualified input causes the PTT to activate, the same in-band signal will be generated at the output. If a CTCSS qualified input causes the PTT to activate then the same CTCSS frequency will be generated at the output. Note When using Fast Output option, the CTCSS tone configured for the input will be generated at the output. Tail Tone When the Tail Tone option is selected, an audible tone of one-second duration is generated at the associated output port immediately before the PTT is switched off. Thus, when a command to deactivate the PTT (for the port with this option selected) is received at the 619DSRI, the 619DSRI will hold the output active for a further second and inject the tone into the outgoing audio: the generated tone is 700Hz. External CTCSS By default, when the output of a port is enabled for sub-audible CTCSS, the CTCSS will be generated on the selected Radio port. By enabling the External CTCSS option (with a CTCSS frequency selected for the Output port), the selected frequency will be removed on the radio port and separated to the CTCSS (DB25) connector. Relay Control The operation of each relay can be configured by selecting an option from the Relay 1 and Relay 2 dropdown lists, as shown in Figure 57. Figure 57. Relay output control The options available in the dropdown list include: ● None specifies that both relays are inactive. ● Remote allows the relay to be manually controlled through a DTMF command or a SELCALL. ● Heartbeat Active causes the relay to be activated each time the Heartbeat function is active. ● Any PTT causes the relay to be activated whenever any PTT is active. 70 Using the Configuration Interface DSRI Alarms Configuration The Alarms configuration page is shown in Figure 58. The values shown here are the default configuration values. You use this page to configure the behaviour of the alarms that can be generated when a digital or analog input changes state. You can also specify conditions under which the alarms will be generated such as monitoring an input and applying a validation period to it prior to generating an alarm condition. Figure 58. Alarms configuration page Configuring Alarm Conditions An alarm can be generated from either Digital Inputs or Analog Inputs. For an input to generate an alarm condition, you need to "enable" the input by selecting it. When an input is enabled, the 619DSRI monitors that input and validates it according to the specified alarm condition described below: • Digital Input The 619DSRI monitors for either a high- or low-active signal depending on the setting you select under Active. The signal must be present for the validation period that you set in the Validation Period field in order for the alarm to be triggered. Once triggered, when the signal returns back to the inactive state, the 619DSRI waits for a fixed two-second validation period before clearing the alarm. • Analog Input The 619DSRI monitors for either a higher or lower level than the value you set in the Threshold Value field for that input. This value must be present for the validation period you set in the Validation Period 619DSRI – Product Manual 71 Chapter 4 field for the alarm to be triggered. Once triggered, when the input level approaches the opposite detection direction and either falls below (in the case of an active-high alarm) or rises above (in the case of an active-low alarm) and is two percent of the threshold value, the alarm is cleared. For example, if the alarm condition is set for an active-high level with a threshold value of 100mV, then an alarm will be triggered when the level reaches or exceeds 100mV for the specified validation period. When the level starts to fall and then drops below 98mV (i.e. 2% of the threshold value), the alarm will be cleared. Similarly, for an active-low alarm condition the same applies except in the opposite direction. To configure the 619DSRI to send out a reporting code associated with an alarm, you specify the port(s) on which to send the reporting code by selecting the port(s) in the "Alarm Selcall Port Enable" section. Any ports that you select will be enabled for sending reporting codes. Hence, when an alarm condition for an enabled port is triggered, the corresponding reporting code is sent out on the ports that you enabled. If multiple ports are enabled, then each reporting code is sent out each enabled port. Reporting Codes In a communications system consisting of a 619DSRI, you may wish to monitor for certain input conditions (i.e. alarms) and report such conditions to a listening device. You can configure the 619DSRI to report any alarms that satisfy the specified conditions by sending reporting codes on its radio ports. The reporting codes are sent using selcall sequence. The format of the reporting code is shown in Figure 59 where PP is the Precode, DDD is the Device Identity, and SS is the Suffix Code. PRECODE P P DEVICE ID D D SUFFIX CODE D S S Figure 59. Format of selcall reporting code The Precode and the Suffix Code are both configured on the Alarms configuration page, and each may contain a maximum of two digits. The Device Identity is set on the General page, and is a fixed length of 3 digits. For example, a reporting of "9100161" is comprised of precode "91", device identity "001", and suffix code "61". While the alarm condition persists, the listening device is required to acknowledge the reported code by replying back to the 619DSRI with an acknowledging selcall. Reporting codes are repeated if no acknowledge code is received from a listening device. Once a reported alarm is acknowledged, the 619DSRI stops sending the reporting code. If the condition that caused the reporting code to be sent is no longer present, the 619DSRI also stops sending the reporting code. Reporting and Acknowledging Alarms The reporting codes are queued for each port that is enabled. As such, reporting codes are sent out in the order that the alarms are triggered. The 619DSRI sends the reporting codes out one at a time and pauses for five seconds between each code. Once all reporting codes have been sent, the 619DSRI pauses again for a further "Alarm Repeat Interval" and then repeats all unacknowledged codes if the associated alarm condition is still present. Whilst the 619DSRI is waiting for the "Alarm Repeat Interval" to elapse, if a new alarm is triggered, the reporting code for that alarm is sent out immediately, and is also added to the enabled ports alarm-code queue. Whilst an alarm condition is still present, the 619DSRI will continue to send out reporting codes until acknowledged. When an acknowledging code is received, the 619DSRI will clear the associated reporting code depending on the status of the control option "Disable Global Alarm Acknowledging" on the General page. By default, the "Disable Global Alarm Acknowledging" is not selected. This means that upon receiving the acknowledging code, the 619DSRI will clear the associated reporting code from being sent out on all enabled ports. However, if the "Disable Global Alarm Acknowledging" is selected, only the port that received the acknowledging code will have its reporting code cleared; and if more than one port is enabled, the other enabled ports will still have the corresponding reporting code sent out until it is either acknowledged or the alarm condition is cleared. 72 Using the Configuration Interface Displaying the Alarm Status The 619DSRI displays the current alarm status on the front-panel LCD and on the System Status page shown in Figure 60. To view the alarm status on the LCD, navigate to the "Display Alarms" item under the "Digital SRI Functions" menu. Figure 60. Displaying the status of the alarms The Alarms section displays the status of the alarms for both the digital inputs and the analog inputs. The status of an alarm is indicated by one of the status codes shown in Table 18. Table 18. Symbols used to display the alarm status Alarm Status Code Description 0 Input not in alarm condition 1 Input in alarm condition * Input in alarm condition and has been acknowledged For example, when a digital input causes an alarm condition, the corresponding status code for that input will change from '0' to '1'. When the alarm condition is acknowledged (at the remote end), the status code will change to an asterisk ('*') character. As shown in Figure 60, none of the inputs is an alarm condition. 619DSRI – Product Manual 73 Chapter 4 DSRI Heartbeat Configuration The Heartbeat page shown in Figure 61 is used to set up functions controlled by the on-board real-time clock. The 619DSRI can perform an automatic periodic output function that can be used for heartbeat or voting purposes. Heartbeat will occur only after the busy inputs to the device have been idle for a period of five seconds. Figure 61. Heartbeat page with an active heartbeat schedule Heartbeat Schedule To use the heartbeat function, you must enable the heartbeat schedule by selecting Active Heartbeat Scheduling under Heartbeat Schedule, as shown in Figure 61. Once the heartbeat schedule is enabled, you can set how the function is invoked by selecting one of the following options: • Always Enabled option sets the heartbeat function to commence operating immediately using the values you specified for the Interval, Duration, and Tone Frequency; and it will remain enabled until you either disable the heartbeat-schedule or select the Active Period option. • Active Period option sets the heartbeat function to operate only for a certain period of the day as specified by the Start Time and the Stop Time, which you can adjust by selecting the hour and the minute for both times (in 24-hour format) using the up and down buttons. Additionally, the Interval, Duration and Tone Frequency will also take effect during the specified Active Period. 74 Using the Configuration Interface Heartbeat Interval The heartbeat interval determines the repeat interval for generating a heartbeat. The value can be changed in increments of 1 second, from a minimum value of 10 seconds to a maximum of 60 minutes. Heartbeat Duration The heartbeat duration specifies the minimum duration between heartbeats. The value can be changed in increments of 1ms up to a maximum period of 2500ms. Tone Frequency The tone frequency specifies the frequency of the heartbeat tone signal. The frequency ranges from 0 to 1000Hz, as shown in Figure 62. Figure 62. Selecting the tone frequency for the heartbeat Tone Output Option on Heartbeat During a Heartbeat period, the ports that will be activated when the heartbeat occurs are those that you have enabled by selecting the Enable option for the port. Figure 63 shows the Tone Output Option on Heartbeat section and the available options, which include: • None for a tone to be generated on that port as specified by the Tone Frequency • CTCSS with a choice of frequencies mixed with the tone specified by the Tone Frequency • In-band with a choice of frequencies mixed with the tone specified by the Tone Frequency Figure 63. Enabling ports for tone output on heartbeat 619DSRI – Product Manual 75 Chapter 4 CTCSS Frequencies Figure 64 shows how to select a CTCSS frequency for the tone output. Select the port followed by the CTCSS option and click on CTCSS to show a list of CTCSS frequencies. Figure 64. Selecting a CTCSS frequency for the tone output In-band Tone Figure 65 shows how to select an in-band tone frequency for the tone output. Select the port followed by the Inband option and click on 2970Hz to show a list of five In-band frequencies. Figure 65. Selecting an in-band tone frequency for the tone output Levels Configuration The Levels menu displays the Levels Configuration pages that are used to set the various signal gains of each port. The configuration page for each port is accessed by clicking on the appropriate port tab; each port page allows you to set the Receive Input, Transmit Output, CTCSS level, and the Tone level for the port as shown in Figure 66. The levels for DTMF and Tone are set on the Other page shown in Figure 67. All signal levels are displayed in decibels (dB). 76 Using the Configuration Interface Figure 66. Levels configuration page showing levels for port 1 Figure 67. Levels configuration page showing other levels Port Levels Each port page allows you to configure the port levels of the 619DSRI, which include the following: • Receive Input is the gain applied to the receive line input of each port and mostly applies gains to incoming Audio and CTCSS frequencies. • Transmit Output is the gain of the transmit line output of each port. • CTCSS is the gain applied to a generated outgoing CTCSS signal of each port. This gain is relative to the transmit output gain. A typical value is -8dB. Additional gains can be applied to the CTCSS by setting the TX Output. 619DSRI – Product Manual 77 Chapter 4 Note The TX Output Level affects the External CTCSS when it is enabled on the output of a port. • DTMF under the Other section is the gain applied to a DTMF/Selcall echo response for each port enabled for remote detection with Selcall/DTMF Echo is enabled. Additional gains can be applied by setting the TX Output Level. • Tone for each port is the gain applied to the generated Tone Reply for DTMF, Selcall, or in-band generated frequencies for each port. Additional gains can be applied by setting the TX Output Level. Other Levels The levels on the Other page include the following: ● DTMF is the gain of the DTMF transmit level. ● V.23 Modem is the gain of the transmit level of the V.23 DSP modem (this is for legacy systems only). ● Tone is the gain of the high and low tone signals. Changing and Saving the Levels When you select a configuration page, the settings for that page are displayed in your web browser. You can change any of the settings by selecting a value from the corresponding dropdown list. Once you change a setting, you must click on the Save button so that the changes are saved back to the 619DSRI; otherwise your changes will be ignored. 78 Using the Configuration Interface Timing Configuration Using the Timing page shown in Figure 68, you can configure the settings that affect the timing of the Busy and PTT signals for each of the eight ports, such as the Busy Validation, the PTT Lead-in, and the PTT Hold time. You can also configure the settings for the Tone Detection delay, and the soft-key off delay for the CTCSS. Figure 68. Settings on the Timing page with corresponding timing diagram The timing diagrams depicted in Figure 69, Figure 70, and Figure 71 show examples of how the value of each setting affects the timing of the corresponding signal, and apply to the settings for port 1. In this example, the busy input is validated at  for 20ms after it is asserted. Once the busy is validated and remains asserted, the PTT output is asserted. The PTT Lead-In delay of 50ms at  is applied to the Selcall/DTMF output signal. The audio input is buffered by the PTT Audio Delay Time at  before it appears at the output. When the busy input is no longer asserted, the PTT Hold time at  ensures that the PTT output remains asserted for an additional 200ms before it is switched off. The Soft Key-Off setting at  ensures that the CTCSS (or Inband Tone) output signal will terminate 50ms before the PTT output signal switches off. 619DSRI – Product Manual 79 Chapter 4 Figure 69. Timing diagram for audio and Selcall/DTMF Figure 70. Timing Diagram for normal CTCSS 80 Using the Configuration Interface Figure 71. Timing diagram for fast-detect CTCSS Busy Validation The Busy validation function specifies the delay period that the Busy (COS) input must be valid before the input is accepted. This option is normally used with normal Busy qualified inputs only and provides a mechanism to compensate for network timing delays. The value can be changed in increments of 10ms and ranges from 0ms to 500ms. PTT Lead-in The PTT Lead-In function specifies the keyup delay of the PTT output so that the PTT is activated before the Selcall/DTMF output. The value can be changed in increments of 10ms and ranges from 0ms to 500ms. 619DSRI – Product Manual 81 Chapter 4 PTT Hold The PTT Hold function specifies the delay period before a PTT output is switched off (relative to the Busy input). The value can be changed in increments of 10ms from 0 to a maximum period of 1500ms. PTT Timeout The PTT Timeout function limits the maximum time that the system will transmit out on the selected ports. This functionality is enabled by default as a safeguard to limit PTT transmissions to the specified timeout value. You can override this function by deselecting the PTT Timeout Enable option; however, it is recommended that you leave this function enabled for normal operation, unless you have a specific need to disable it. The value can be changed in increments of one second and ranges from 30 to 1800 seconds; and the default value is 300 seconds. Note Disabling the PTT Timeout function is not recommended as it removes the safeguard that prevents an external PTT from locking the system in a PTT state. Tone Detect During the detection period of a CTCSS signal, the value selected specifies the period of time that the microcontroller will wait for a CTCSS signal to be present (after the Busy becomes active). This value is also used to provide a level of tolerance for the loss of a tone (once the signal is detected). The value can be changed in increments of 10ms and ranges from 150ms to 1000ms. Soft Key-Off The Soft Key-Off function specifies the period at which the CTCSS signal will terminate (relative to the PTT output). This period would always be shorter than the period set for PTT Hold. The value can be changed in increments of 10ms and ranges from 10ms to 5000ms. Fast Tone Lockout Fast Tone lockout provides a level of protection against weak signals. Any port that generates a PTT Output, but then fails to detect a CTCSS signal and switches off after the detection period, will be locked out for a specified period of time. This period is set by changing the “Fast Tone Lockout” figure to a value greater than zero seconds. However, note that only the Busy(s) associated with the port(s) that failed to detect a CTCSS signal are affected. Outputs from the port(s) are not affected. Values can be changed in units of one second and ranges from 0 to 30 seconds. System Split Timeout The System Split function allows you to temporarily change the default configuration from the primary configuration to the secondary configuration when initiated via a DTMF command or a SELCALL command. The System Split Timeout setting determines the period that the system-split function will remain in effect after the secondary configuration is invoked via a DTMF command or SELCALL command. Thus, If the secondary configuration is invoked via a DTMF or SELCALL command, the value specified for the System Split Timeout will determine the period of time that the secondary configuration will remain set as the default configuration. At the end of this period, the 619DSRI will automatically restore the primary configuration as the default. The value can be changed in increments of one minute and ranges from 0 to 120 minutes. 82 Using the Configuration Interface Note If you set the System Split Timeout to zero, the DSRI will not automatically restore the primary configuration as the default. In the example shown in Figure 72, transceivers are connected to port 1 and port 2, and a repeater station is connected to port 3 of the 619DSRI. Figure 72. Example configuration using the System Split function Figure 73 shows the primary configuration for this example, which allows audio to be routed as follows: • Port 1 TX/RX, Port 2 TX/RX and the TTR (Talk Through Repeater) at Port 3 are all within the network of communication. If the secondary configuration shown in Figure 74 is invoked via a DTMF command, the audio will be routed as follows: • The repeater at Port 3 will be excluded from the network and communication will be possible between Port 1 TX/RX and Port 2 TX/RX only. The system is now split for the period of time set by the value specified by the System Split Timeout, which in this case is 15 minutes. Figure 73. Example of System Split Timeout with default primary configuration 619DSRI – Product Manual 83 Chapter 4 Figure 74. Example of System Split Timeout invoking the secondary configuration CTCSS Hold Time The CTCSS tone talk off hold time period located under Other Timing is a configurable timer that will hold an Active CTCSS state on if there is momentary interruption. This is typically caused by destructive interference between spoken audio and the CTCSS signal. This parameter may be set in steps of 10ms. For example, if a CTCSS tone talk off hold time period of 200ms is required, you should enter the value of 20. Radio Port Audio Delay The settings under Radio Port Audio Delay allow you to apply a configurable delay to the audio as it passes through the DSRI device. This allows for radio paths with a long setup time, preventing the first syllable of spoken audio from being cut off. This can be configured for any of the first four audio ports. It is configurable from 0 to 3000 milliseconds in steps of 500 milliseconds. • Audio Delay Enable enables the audio-delay feature that buffers the audio input before it appears at the audio output. • Audio Delay Time specifies the delay to impose on the transmission of audio from 0 to 3000 milliseconds in steps of 500 milliseconds. 84 Using the Configuration Interface E & M Configuration The E & M page shown in Figure 75 provides configuration settings for the E & M (Ear and Mouth) operation for each of the eight data ports. You can set the following parameters for each port: • PTT Output Control sets the type of output control for the PTT output. The available values are: Contact, Voltage, Switched Ground, and Switched Power. The default value is Contact. • BUSY Input Control sets the type of input control for the BUSY input. The available values are the same for the PTT Output Control. The default value is Voltage. Figure 75. E & M configuration page showing settings for port 1 Table 19 lists all the possible E and M configuration options. Choose one E (Busy) option and one M (PTT) option. Table 19.

Omnitronics may release new versions of the firmware from time to time to add additional features or to resolve issues. This page is not intended for end-users as it available only to system administrators and is accessible only under the Supervisor account. You can view the version of firmware loaded into the 619DSRI on the System Status page (see “Viewing the System Status” on page 34). After you have upgraded the firmware, the configuration settings in the device may return to the factory default settings. It is recommended that you back up the configuration settings with the Save / Restore menu (see “Saving the Configuration” on page 31,) before upgrading the firmware. Figure 77 shows the Firmware Upgrade page. Figure 77. Upgrading the firmware in the DSRI To upgrade the firmware in the 619DSRI, click the Browse button to locate the file on your computer: the firmware file is identified with a .bin.gz extension. Once you have selected a file, the full path and filename will appear in the Select file box. Important Do not use decompression software to decompress the .bin.gz file; the dvice uses the compressed binary image to save space in flash memory. If you decompress the file, the device will reject the file as invalid. Once you have selected a firmware file, the full path and filename will appear in the Select file text box. To commence the firmware upgrade process, click the Upgrade button. Warning Do not remove power to the device during the upgrade process, as it may cause damage to the device or corrupt the firmware. While the firmware upgrade is in progress, the upgrade page will display a progress indicator to keep you informed of the upgrade progress. Figure 78 shows the status while the firmware transfer is in progress. 619DSRI – Product Manual 91 Chapter 5 Figure 78. Transferring the firmware to the device Once the firmware is transferred to the device, it is then programmed into flash memory, as shown in Figure 79. Figure 79. Firmware upgrade in progress Once the programming is complete, the firmware will then verified to ensure it was programmed without any errors, as shown in Figure 80. Figure 80. Verifying the firmware 92 Diagnostics and Upgrading the Firmware Once the firmware upgrade process is complete, the page will display a message indicating that the firmware has been successfully loaded into flash memory, and a Restart button will appear allowing you to restart the device, as shown in Figure 81. The new firmware will not run until the device is restarted. Note If the device fails to upgrade the firmware, do not remove the power: try repeating the firmware upgrade process again. Figure 81. Firmware verified and loaded into flash memory Click the Restart button to restart the device. The 619DSRI will immediately restart and the upgraded firmware will be loaded. Whilst the 619DSRI is restarting, you will see the Restart in Progress page, as shown in Figure 82. Figure 82. Restarting the device after upgrading the firmware Once the device has restarted, you may need to log in again at the Log-In page if you want to check the configuration settings or configure the device. 619DSRI – Product Manual 93 Appendix A Application Scenarios This chapter provides several examples of connecting radios to 619DSRI devices in a network, and includes the following sections: ● “Voice Data Segregation” ● “Optimization of Link Traffic Flow” on page 96 ● “Fast Link Keying” on page 97 ● “Conversion of Keying/Squelch Mechanisms” on page 98 Voice and Data Segregation The requirement of this example is to provide voice and data segregation on a shared radio network. To achieve this requirement, voice and data transmissions are assigned different CTCSS tones. The 619DSRI will distinguish between the two different CTCSS tones and create two separate paths: one for data and one for voice. Figure 83 shows the typical connection required for this scenario, which includes the following features: ● Programmable CTCSS detection of dual frequencies ● CTCSS steering through dynamic switching ● CTCSS generation dependent on the input source Figure 83. Application example of voice and data segregation 619DSRI – Product Manual 95 Appendix A In this scenario, Port-3 is set up to act on either of two CTCSS frequencies, T1 (100.0Hz) or T2 (118.8Hz). Port5, the voice link, is configured to receive and transmit T1 and Port-1, the data link, is configured to use T2. Voice traffic from Port-5 and Data traffic from Port-1 are both routed to Port-3 where either of T1 or T2 is generated into the repeater, depending on the initiating input. When a signal on Port-3 is detected with T1, an optional configuration is invoked which steers the signal to the voice port only and generates sub-audible T1. Conversely, when a signal on Port-3 is detected with T2, a different optional configuration is invoked which steers the signal to the data port only and generates sub-audible T2 into the link. Optimization of Link Traffic Flow The requirement of this example is to optimize voice and data traffic across a series of radio links and increase the channel availability of connected repeaters. This is example is similar to the previous example in which voice and data are allocated different CTCSS frequencies. The 619DSRI will distinguish between the two different frequencies on the common link backbone and provide CTCSS steering and dynamic switching at the link ports. This reduces traffic at repeater sites thereby improving system performance Figure 84 shows the typical connection required for this scenario, which includes the following features: ● Programmable CTCSS detection of dual frequencies. ● CTCSS steering through dynamic switching. ● CTCSS generation dependent on the input source. ● Selective configurations. Figure 84. Application example of optimization of link traffic flow In this scenario, voice signals use T1 (100.0Hz) and data traffic uses T2 (118.8Hz). Ports 1 and 8 are connected to the link and are set up to handle both CTCSS frequencies. Port-6 connects to a VHF voice network and is set up for T1 only. Port-3 connects to a UHF data network and is set up for T2 only. Audio on either of the link ports is always routed to the other by default. However, the same audio is only routed to either of the voice or data ports (or repeaters) depending on the received CTCSS tone. This is achieved through CTCSS steering of T1 and T2 at the link ports and by invoking one of four pre-set optional configurations. 96 Application Scenarios On the link side, each link port will invoke one of two optional configurations to allow the incoming signal to be dropped onto the appropriate repeater port. Each optional configuration will remain active, and create a temporary link, only whilst the input tone is available. On the network side, each repeater port is configured to insert audio into both link ports. When this occurs, the link ports will also generate a sub-audible tone (T1 or T2), depending on which repeater has keyed the link. Fast Link Keying The requirement of this example is to eliminate long delays in CTCSS controlled multi-hop links. The 619DSRI incorporates a fast CTCSS mode for input signals. When configured correctly, fast CTCSS causes a PTT to be asserted in anticipation of a subsequent CTCSS tone. And to reduce the effects of possible false triggering, a temporary lockout feature can also be applied. Figure 85 shows the typical connection required for this scenario, which includes the following features: ● Fast CTCSS output on COS. ● Programmable tone detect period. ● Programmable false trigger lockout. Figure 85. Application example of fast link keying In this scenario, the link backbone is to be keyed as fast as possible, using a given CTCSS tone (100.0Hz). The link ports are configured as Ports 1 and 5. Port-3 is used to connect a repeater network. All three ports are set up for Fast CTCSS on frequency 100.0Hz. Each port is also configured to generate 100.0Hz. When the COS input of Port-1 activates, PTTs are immediately activated on Ports 5 and 3, and a 100.0Hz CTCSS tone is generated on each of those ports. If the required CTCSS tone is not detected within a given period then the outputs are deactivated, regardless of the COS input state. If the tone is detected, the outputs will remain active until either the COS is removed or the tone is lost. Similar operation takes place on each of the other ports. 619DSRI – Product Manual 97 Appendix A Conversion of Keying/Squelch Mechanisms The requirement of this example is to interface private or leased lines to multiple groups of mobile users. Each mobile group is serviced by different repeaters and with different CTCSS frequencies and the lines use In-band keying. The 619DSRI can be programmed to accept audio that is qualified with a specific In-band keying tone, such as 2600Hz, or a CTCSS frequency. The audio can be routed to desired ports and, on transmission, a specified keying tone or a CTCSS tone can be sent with the out-going audio. Figure 86 shows the typical connection required for this scenario, which includes the following features: ● Independent sub-audible and In-band tone transceivers ● CTCSS Translation ● Programmable detection and generation of sub-audible Figure 86. Application example of conversion of keying/squelch mechanisms In this scenario, a large courier company has three groups of mobile users communicating through three repeater networks. Each network uses a different CTCSS frequency to prevent unwanted interruptions. A dispatch operator at the base can talk and monitor each group of users. This is done through a private 2-wire line that uses a 2600Hz keying tone. The 619DSRI will automatically perform tone to CTCSS conversion to enable the dispatcher to talk to the mobile fleet. Conversely, the device also performs CTCSS to 2600Hz tone conversion, so that when mobiles talk, the dispatcher can listen to their conversations. When more than one network is active, the 619DSRI will mix the received signals for the operator, regardless of the incoming CTCSS tones. 98 Application Scenarios Appendix B Technical Reference This appendix provides product specifications and the pin assignment for connectors used by the product, and includes the following sections: ● “Specifications” ● “4-Wire Port Characteristics” on page 103 ● “E & M Configuration Options” on page 105 Specifications The specifications of the 619DSRI product are listed in several tables on the following pages: Table 20 lists the general specifications, Table 21 lists the specifications for the radio ports, and Table 22 lists the specifications for the external interfaces.

Adaptive DPCM (ADPCM) A variant of DPCM that varies the size of the quantization step, to allow further reduction of the required bandwidth for a given signal-to-noise ratio (SNR or S/N). Advanced Encryption Standard (AES) Also known as Rijndael and is a block cipher adopted as an encryption standard by the U.S. government. It has been analyzed extensively and is now used worldwide Busy Indicates incoming audio from line inputs (transceivers, base stations, and phone lines). Sometimes referred to as COR (Carrier Operated Relay) or Busy. Class ‘A’, ‘B’ and ‘C’ Addresses IP or Internet addresses can be grouped into 3 classes: Class ‘A’, ‘B’ and ‘C’. The different classes allow for more or less computers on a network. The value of the first number in the IP address determines which class the address belongs to and how many computers are allowed on that network Class ‘A’ Addresses in the range: 1.0.0.0 - 126.255.255.255. Addresses in this range are used as global addresses on the Internet, and are usually allocated by a global registry. Class ‘B’ Addresses in the range: 128.0.0.0 - 191.255.255.255 Addresses in this range allow for up to 65532 hosts on a network and are typically used for large organizations Class ‘C’ Addresses in the range: 192.0.0.0 - 223.0.0.0. Addresses in this range allow for up to 254 hosts on a network and are typically used for LANs. In addition certain address ranges are reserved for private use and are normally those that an organisation will use for its internal networks. These private use network addresses are: 10.0.0.0 - 10.255.255.255, 72.16.0.0 - 172.31.255.255, 192.168.0.0 192.168.255.255 Note: Each of the Class ‘A’, ‘B’ and ‘C’ address ranges shown above provides a private use set of addresses. Typically, small LANs will use addresses in the 192.168.0.1 - 192.168.0.255 range. Codec A device or program capable of performing encoding and decoding on a digital data stream or signal. The word codec may be a combination of any of the following: Compressor-Decompressor, Coder-Decoder, or Compression/Decompression. Codecs (in the modern, software sense) encode a stream or signal for transmission, storage or encryption and decode it so that it is in a format suitable for viewing or for radio. The codecs used in the 619DSRI are audio codecs and provide data compression to decrease the amount of bandwidth required to transmit the audio data. COR/COS Refers to Carrier Operated Relay/Carrier Operated Squelch and is used in the same way that Busy is used. 619 Digital Smart Radio Interface – Product Manual 109 CTCSS Continuous Tone Coded Squelch System. Data Encryption Standard (DES) A block cipher with a key length of 56 bits. It is the least secure of the algorithms supported because it uses a short key. Differential (or Delta) Pulse-Code Modulation (DPCM) encodes the PCM values as differences between the current and the previous value. For audio this type of encoding reduces the number of bits required per sample by about 25% compared to PCM. Domain Name System (DNS) Stores and associates various sorts of information with so-called domain names; most importantly, it serves as the 'phone book' for the Internet: it translates humanreadable computer hostnames, e.g. omnitronics.com.au, into the IP addresses that networking equipment needs for delivering information. It also stores other information such as the list of mail exchange servers that accept e-mail for a given domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use. Dynamic Host Configuration Protocol (DHCP) A set of rules used by communications devices such as a computer router or network adapter to allow the device to request and obtain an IP address from a server which has a list of addresses available for assignment. DHCP is a protocol used by networked computers (clients) to obtain IP addresses and other parameters such as the default gateway, subnet mask and IP addresses of DNS servers from a DHCP server. It facilitates access to a network because these settings would otherwise have to be made manually for the client to participate in the network. The DHCP server ensures that all IP addresses are unique, e.g., no IP address is assigned to a second client while the first client's assignment is valid (its lease has not expired). Thus IP address pool management is done by the server and not by a human network administrator. DTMF Dual Tone Multi-Frequency Encryption The process of obscuring information to make it unreadable without special knowledge. FIFS First In First Served FSK Frequency Shift Keying Gateway A default gateway is used by a host when an IP packet's destination address belongs to some place outside the local subnet (thus requiring more than one hop of Ethernet communication). The default gateway address is usually an interface belonging to the LAN's border router or firewall. GSM The first digital speech coding standard used in GSM (Global System for Mobile Communications) digital mobile phone system. The bit rate of the codec is 13kbit/s. G.711 This is an ITU-T standard for audio companding. It is primarily used in telephony. G.711 is a standard that represents 8 bit compressed pulse code modulation (PCM) samples for signals of voice frequencies, sampled at the rate of 8000 samples/second. A G.711 encoder will create a 64kbit/s bit-stream. There are two main algorithms defined in the standard, mu-law algorithm (used in North America & Japan) and a-law algorithm (used in Europe and the rest of the world). Both are logarithmic, but the later a-law was specifically designed to be simpler for a computer to process. The standard also defines a sequence of repeating code values which defines the power level of 0dB. G.726 G.726 is ITU-T speech codec operating at bit rates of 16-40kbit/s. The most commonly used mode is 32kbit/s, since this is half of the rate of G.711, thus increasing the usable network capacity by 100%. G.726 is based on ADPCM 110 Glossary technology. HTML Short for HyperText Markup Language, is the predominant markup language for the creation of web pages It provides a means to describe the structure of text-based information in a document. HTML is written in the form of labels (known as tags), surrounded by angle brackets < and >. Internet Protocol (IP) This is a data-oriented protocol used by source and destination hosts for communicating data across a packet-switched network such as the internet. Jitter Buffer Used to counter jitter introduced by packet networks so that a continuous play-out of audio (or video) transmitted over the network can be assured. The maximum jitter that can be countered by a de-jitter buffer is equal to the buffering delay introduced before starting the play-out of the media-stream. Mean Opinion Score (MOS) Provides a numerical measure of the quality of human speech at the destination end of the circuit. The scheme uses subjective tests (opinionated scores) that are mathematically averaged to obtain a quantitative indicator of the system performance. Multicast A protocol for efficiently sending to multiple receivers at the same time over TCP/IP networks, by employing a multicast address. Traditional techniques for sending IP packets include Unicasting and Broadcasting. Unicast transmissions are point-to-point only. If you want to send a packet to ten different destination devices then you must transmit ten copies of the same packet. This floods the network with unnecessary traffic. Broadcast transmissions overcome this problem by sending just one copy of a packet (i.e. point to multipoint). However, broadcast transmissions cannot easily traverse a WAN and they end up being processed by all devices on a network, regardless of whether the device needs the ‘packetized’ data or not. Multicasting overcomes these problems. Using multicasting, the IPR110Plus sends one copy of a packet to a group of receivers that want to receive it. Network Address Translation (NAT) Involves re-writing the source and/or destination addresses of IP packets as they pass through a router or firewall. Most systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address. In a typical configuration, a local network uses one of the designated ‘private’ IP address sub-nets (such as 192.168.x.x or 10.x.x.x), and a router on that network has a private address (such as 192.168.0.1) in that address space. The router is also connected to the Internet with a single ‘public’ address (known as ‘overloaded’ NAT) or multiple ‘public’ addresses assigned by an ISP. Netmask A network mask, also known as a subnet mask, netmask or address mask, is a bit mask used to show how much of an IP address identifies the sub network the host is on and how much identifies the host. Pulse-Coded Modulation (PCM) A digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals and then quantized. Real Time Protocol (RTP) Defines a standardised packet format for delivering audio and video over the Internet. It can be used in both multicast and unicast applications. It is built on top of User Datagram Protocol. Simple Network Management Protocol (SNMP) is the network management protocol used almost exclusively in TCP/IP networks. SNMP provides a means to monitor and control network devices, and to manage configurations, collection of statistics, performance and security. 619DSRI – Product Manual 111 Side-tone Sound that is picked up by the telephone's mouthpiece and introduced (at low level) into the earpiece of the same handset, acting as feedback. Side-tone provides users with confidence that the handset is actually working. Transmission Control Protocol (TCP) TCP is one of the core protocols of the Internet protocol suite. Using TCP, programs on networked computers can create connections to one another, over which they can send data. The protocol guarantees that data sent by one end-point will be received in the same order by the other, and without any pieces missing. Time To Live (TTL) This determines the number of network routers that will pass on the data packets from this unit. This value limits how far the message will be sent. Typically as a router passes on a data packet, it will decrease the TTL information in the data packet, once the TTL reaches zero, the message will no longer get forwarded. Unicast The sending of information packets to a single destination. User Datagram Protocol (UDP) UDP is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages known as Datagram to one another. UDP does not provide the reliability and ordering guarantees that TCP does; Datagram may arrive out of order or go missing without notice. However, as a result, UDP is faster and more efficient for many light weight or timesensitive purposes. Voice Operated Switch (VOX) VOX is a switch that operates when sound over a certain threshold is detected. It is usually used to turn on a transmitter when someone speaks and turn it off when they stop speaking. It is used instead of a push-to-talk button. 112 Glossary Index A alarm reporting codes about, 72 device identity, 72 format of, 72 precode, 72 sending, 72 suffix code, 72 alarm status codes description of, 35, 73 displaying, 35, 73 alarms acknowledging, 72 conditions, 71 configuring, 71 reporting, 72 reporting codes.
