Series Version 8.3 Table of Contents | 6 Chapter 1 | About the XT Series The Avaya Scopia® XT Series is a set of dedicated videoconferencing endpoints which incorporate state-of-the-art video technology for high definition (HD) conferencing. You can also locally host videoconferences with the built-in MCU on most XT Series models. The XT Series seamlessly works with a wide variety of endpoints, including H.323, SIP, Scopia® Desktop Clients, Scopia® Mobile devices, and ISDN endpoints (via Scopia® 100 Gateway). Figure 1: XT Series products This section provides an overview of the general features and capabilities available in the XT Series: • The XT Series is a dedicated videoconferencing endpoint which can also host its own videoconferences with its built-in MCU, without requiring an external MCU. • Excellent video quality, with resolutions of up to 1080p at an unprecedented 60 frames per second (fps), depending on the model. • Support for dual HD video streams, allowing PC presentations to be shared alongside video from the camera in resolutions of up to 1080p at 60fps, depending on the model. • Seamlessly share data and presentations with third-party endpoints. • DVD-quality audio with up to 48 kHz sampling rate audio encoding capability, depending on the model. The sampling rate is a measure of the accuracy of the audio when it is digitized. The XT Series endpoints are shipped with different microphones depending on the model. You can add dedicated Microphone Pods or additional analog microphones if required. • High quality video and audio even with limited bandwidth or poor network conditions, by using two compression methods: – H.264 Scalable Video Coding Technology (SVC) in point-to-point calls. SVC extends the H.264 codec standard to dramatically increase error resiliency and video quality without the need for higher bandwidth. – H.264 High Profile is a standard for compressing video by up to 25% over the H.264 Baseline Profile, enabling high definition calls to be held over lower call speeds. It requires both sides of the transmission (sending and receiving endpoints) to support this protocol. – NetSense is a proprietary Scopia® Solution technology which optimizes the video quality according to the available bandwidth to minimize packet loss. As the available bandwidth of a connection varies depending Deployment Guide for Avaya Scopia® XT Series Version 8.3 About the XT Series | 7 on data traffic, NetSense's sophisticated algorithm dynamically scans the video stream, and then reduces or improves the video resolution to maximize quality with the available bandwidth. • Ability to record and playback videoconferences using a USB drive (may require license, depending on the model). • For an even better experience, Scopia® Control enables you to remotely control the XT Series features using the intuitive touch interface of an Apple® iPad® (may require license, depending on the model). • Secure point-to-point video calls and videoconferences, via encrypted connections or using TLS certificates. You can have up to three remote encrypted participants in a videoconference. Important: Using encryption is subject to local regulation. In some countries it is restricted or limited for usage. For more information, consult your local reseller.

An MCU, or Multipoint Control Unit, connects several endpoints to a single videoconference. It manages the audio mixing and creates the video layouts, adjusting the output to suit each endpoint's capabilities. Deployment Guide for Avaya Scopia® XT Series Version 8.3 About the XT Series | 12 Figure 7: Hosting a videoconference on the XT Series You can add a license to most XT Series models to activate the built-in MCU to host videoconferences locally (see Registering and Enabling the License on page 69): • MCU4 can host videoconferences with up to four participants (one local, three remote). • MCU9 can host videoconferences with up to nine participants (one local, eight remote). Important: The Scopia® XT Executive can host up to four participants. The embedded MCU can mix standard definition and HD endpoints in the same meeting, without one impacting on the other. The built-in MCU also supports both wide-screen (16:9) and standard formats (4:3), incorporating them seamlessly into the video layout. While generating the video layout, the built-in MCU must shrink each participant's image to fit the layout. So while the composite video layout remains in HD, each participant's image within the layout can reach a maximum resolution of 448p. When using the XT Series as an MCU only, not participating locally, we recommend blocking the audio and video input from this XT Series during the meeting. For the best experience when using the Avaya Scopia® XT Series MCU Edition, we recommend activating the license known as High Bandwidth Option (12Mbps total for all participants) to avoid sending video at the default lower 6Mbps total for all participants (see Registering and Enabling the License on page 69).

Choose if you want to remotely control your XT Series (Controlling the XT Series on page 57). To use the XT Remote Control Unit, first connect a monitor (Connecting Monitors to the XT Series on page 38). Otherwise, use the web interface to control the system (see Accessing XT Series Web Interface on page 63). 6. Register your license to activate the XT Series (see Registering and Enabling the License on page 69). Without a license key to activate the product, you can only use the system in preview mode for 24 hours. 7. Get started with the basic configuration to use the XT Series, as described in Initial Configuration of the XT Series on page 69, including running the quick setup wizard, and defining network settings. 8. (Recommended) You can prevent users from altering advanced settings by changing the default administrator PIN code, and you can optionally set a user PIN code to protect basic settings too (see Setting PIN Codes for the XT Series on page 138). To change the default login settings for the XT Series web interface, see Securing Web Access to the XT Series on page 139.

If your XT Series is an endpoint, not just a server, configure your camera and microphone settings, as described in: • Configuring Cameras on page 87 • Configuring Microphones on page 90 10. If necessary for your deployment, configure your advanced network and call settings, as described in Configuring Advanced Network Settings on page 99. This includes, for example: • Setting the IP address • Configuring the system in a SIP deployment • Configuring call settings • Enabling NAT and Firewall Traversal • Registering the system with the gatekeeper • Configuring the system to use an LDAP directory For more information about deployment setups, see Planning the Topology of the Avaya Scopia® XT Series Deployment on page 19 and the Avaya Scopia® Solution Guide. 11. (Optional) If necessary for your organization, you can secure videoconference sessions via encrypted connections and TLS certificates (see Securing your XT Series on page 138). Important: Using encryption is subject to local regulation. In some countries it is restricted or limited for usage. For more information, consult your local reseller. 12. If your deployment includes Scopia® Management, you can set up remote monitoring and management of the XT Series using SNMP messages to send alerts to a central SNMP server (see Sending Status with SNMP on page 133).. 13. You can remotely backup and restore the XT Series configurations via Scopia® Management, as described in Enabling System Logs and Remote Initialization on page 155, or use the same configuration files to duplicate the same settings across multiple endpoints in an organization. 14. To update your software, see Updating the XT Series on page 135. Some upgrades require an updated license. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Initial Workflow for Deploying the Avaya Scopia® XT Series | 18 Chapter 3 | Planning the Topology of the Avaya Scopia® XT Series Deployment There are a number of ways that the Avaya Scopia® XT Series can be deployed in a network, depending on whether you use it as a room system endpoint or a conference hosting system, and the type of the endpoints connecting to the unit. As you add more XT Series endpoints, you can manage them centrally with Avaya Scopia® Management. This would enable centralized updating, backing up and control.

Scopia® XT Executive integrates advanced videoconferencing into a high resolution 24-inch multimedia LED monitor. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 19 Figure 8: Avaya Scopia® XT Series as Endpoints Planning the Topology of Avaya Scopia® XT Series with Scopia® XT Desktop Avaya Scopia® XT Series SMB Edition enables you to locally host videoconferences using its built-in MCU, and extends your videoconferences to participants joining from a computer (with Scopia® Desktop Client) or a mobile device (using Scopia® Mobile). For example, when you start a videoconference with the XT Series hosting the call, you can add other participants by asking them to connect via a web link to the Scopia® XT Desktop server, which would automatically install and launch Scopia® Desktop Client on their computers, or Scopia® Mobile on their mobile devices. The main features of the Avaya Scopia® XT Series SMB Edition include: • Remote users can easily connect to a meeting hosted by the built-in MCU on the XT Series, by connecting via the Scopia® XT Desktop server. The deployment has very few components. You do not need additional hardware like an external MCU, Avaya Scopia® PathFinder for firewall traversal, or Avaya Scopia® ECS Gatekeeper for routing calls. • The included Scopia® XT Desktop provides built-in NAT and firewall traversal functionality, enabling secure remote connections from Scopia® Mobile and Scopia® Desktop Clients. You can enable this functionality via the XT Series license. The Avaya Scopia® XT Series SMB Edition includes the following options: • Full SMB4 - Basic MCU level with up to four participants: one local and three remote endpoints or PC clients. • Full SMB9 - Advanced MCU level, with one local participant and up to eight remote endpoints or PC clients. There is no local endpoint if you deploy the XT Series as a server. Important: The Scopia® XT Executive can host up to four participants. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 20 Figure 9: Avaya Scopia® XT Series SMB Edition Deployment on page 21 shows a typical topology for the Avaya Scopia® XT Series SMB Edition solution. For more information, see the Solution Guide for Scopia® Solution. Figure 9: Avaya Scopia® XT Series SMB Edition Deployment As you add more XT Series endpoints, you can also manage them centrally with Scopia® Management. This would enable centralized updating, backing up and control. Planning NAT and Firewall Traversal with Avaya Scopia® XT Series The Avaya Scopia® XT Series fully supports NAT and firewall traversal, enabling you to place the unit behind a NAT router or firewall and connect with other endpoints seamlessly. This section describes the available methods to incorporate NAT and firewall traversal with XT Series: • Using a Avaya HTTP server or a STUN public server for NAT and firewall traversal When the XT Series hosts a videoconference with endpoints outside the enterprise (Figure 10: Using an HTTP/STUN Server for NAT and Firewall Traversal on page 22), it first queries an HTTP or STUN server to discover its public IP address, then sends it to any external endpoints wishing to join the conference. The external endpoints then answer the call using the IP address provided. Configure the XT Series for HTTP or STUN autodiscovery. A STUN server enables you to directly dial an endpoint behind a NAT or firewall by giving that computer’s public internet address. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 21 Figure 10: Using an HTTP/STUN Server for NAT and Firewall Traversal This approach works well in simple NAT and firewall traversal deployments, typically used by home offices and Small Medium Businesses (SMBs). • Using PathFinder server or other H.460 server for NAT/firewall traversal Endpoints in the private network can communicate with public endpoints via an H.460 NAT/firewall traversal server, like the PathFinder (see Figure 11: Using a separate NAT and Firewall Traversal Server on page 23). Endpoints in the public network can join a conference hosted in the private network via the traversal server if there is an open connection through the firewall. A dedicated PathFinder server offers external endpoints a static address when joining conferences hosted in your organization. You can dial [email protected] to access from outside the firewall, or you can dial 1234 directly if you deployed the Scopia® PathFinder client. Configure the PathFinder server as the XT Series's gatekeeper and enable H.460. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 22 Figure 11: Using a separate NAT and Firewall Traversal Server • Using the XT Series for NAT and firewall traversal In cases where your organization has no sophisticated firewall protection, the XT Series can straddle the two network zones using the both network ports provided on the XT Codec Unit (see Figure 12: Using XT Series for NAT and Firewall Traversal on page 24). Activate the second network port with the correct license, then connect one port to the public network and the other to your private network. All communication passes through the XT Series which acts as the virtual conference room for all the endpoints. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 23 Figure 12: Using XT Series for NAT and Firewall Traversal A gatekeeper allows the XT Series to dial aliases instead of IP addresses for endpoints in the private network, while for public endpoints, you must dial IP addresses. Without a gatekeeper, all endpoints must be referenced using IP addresses. Supporting ISDN Connectivity About this task The Avaya Scopia® XT Series supports ISDN connectivity, allowing calls from endpoints to be routed to the relevant videoconference via the Scopia® Gateway for ISDN. For deployments without a gatekeeper, you can dial ISDN endpoints by simply dialing the ISDN number. To do so, you must first configure the endpoint with your Scopia® Gateway for ISDN, as described below. The system then automatically and transparently takes care of setting the bit rate and call routing through the Scopia® Gateway. A single gateway can serve multiple endpoints. For example, if your organization needs to enable 5 Avaya Scopia® XT Series endpoints with ISDN connectivity (at a speed of 256bps), you can use one the Scopia® Gateway for ISDN, which supports 5 concurrent calls of 256bps each. With the gateway approach less communication lines are needed. As all gateways do not connect at the same time and not all calls are ISDN, many more endpoints can share the same ISDN connection and gateway. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 24 Before you begin Enable Peer-to-Peer mode in the Scopia® Gateway for ISDN. For more information, see the Scopia® Gateway documentation. Procedure 1. Access the XT Series web interface, as described in Accessing XT Series Web Interface on page 63. 2. Select Administrator Settings > Protocols > ISDN. 3. Configure the IDSN settings as described below: Figure 13: Enabling ISDN connectivity Table 5: Supporting ISDN Connectivity Field Description Enable Select Yes to allow this Avaya Scopia® XT Series to quickly dial ISDN endpoints via the Scopia® Gateway for ISDN. Gateway IP Address Enter the IP address of the Scopia® Gateway for ISDN used by your organization. 4. Select Save. Implementing External API Control You can control the XT Codec Unit using the Avaya Scopia® XT Series API (requires integration with AMX, Creston, or Extron control devices). Contact Avaya customer support to receive the Reference Guide for Avaya Scopia® XT Series API, which includes the list of commands over the Ethernet interface. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 25 Implementing Port Security for the Avaya Scopia® XT Series The Avaya Scopia® XT Series provides video technology for room conferencing, including support for dual stream 1080p video, high quality data sharing, high quality full band audio and a high-capacity embedded MCU (selected models). To enable an external XT Series endpoint to communicate with Scopia® Solution components within the organization's network, you need to open firewall ports between the external XT Series endpoint and the organization. This section details the ports used for the Avaya Scopia® XT Series and the relevant configuration procedures: Navigation • Opening Ports for the XT Series on page 26 • Configuring the TCP or UDP Port Range on the Avaya Scopia® XT Series on page 32 Opening Ports for the XT Series You can deploy Avaya Scopia® XT Series endpoints either inside or outside the enterprise network. When Scopia® Solution components are located inside the network, and one or more XT Series endpoints are outside the network, you must open ports in the firewall to enable the endpoint's functionality. Since the location of the XT Series is not fixed, the ports' source and destination differ depending on your XT Series topology. There are two main deployment topologies for the XT Series, each with optional additional components: • XT Series as an endpoint (standard topology) • XT Series with Scopia® XT Desktop (Avaya Scopia® XT Series SMB Edition) Typically, XT Series endpoints connect to a conference managed by Scopia® Management, and hosted on the Scopia® Elite MCU. XT Series endpoints may be both within and outside the enterprise. See Figure 14: Standard topology for Avaya Scopia® XT Series on page 26 Figure 14: Standard topology for Avaya Scopia® XT Series In contrast, in the Avaya Scopia® XT Series SMB Edition topology, Scopia® Desktop Clients join the conference via Scopia® XT Desktop server, located in the DMZ. The Scopia® XT Desktop server then connects to an XT Series endpoint with built-in MCU located inside the enterprise. External and internal Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 26 XT Series endpoints connect directly to the XT Series endpoint with built-in MCU. See Figure 15: Avaya Scopia® XT Series SMB Edition topology on page 27. Figure 15: Avaya Scopia® XT Series SMB Edition topology Avaya Scopia® PathFinder provides a complete firewall and NAT traversal solution for H.323 deployments, enabling secure connectivity between enterprise networks and remote sites. PathFinder enables registered external endpoints to traverse the firewall without requiring you to open any dedicated ports for the XT Series. See Figure 16: XT Series deployment with PathFinder on page 27 Figure 16: XT Series deployment with PathFinder In each of the topologies, the XT Series can be located either inside or outside the enterprise. You need to open different ports depending on the topology, and the location of the endpoints. The source for a port is the sender of data packets, and the destination is the receiver. There are two types of ports which require opening (see Figure 17: Inbound and outbound ports for the XT Series on page 28): • Bidirectional ports, which allow the XT Series to send and receive data packets on the same port. • Unidirectional ports, which allow the XT Series to either initiate communication or receive data packets. For a unidirectional port, you must designate it as inbound or outbound. A port is inbound if its source is sending to a destination protected by the firewall (for example, data sent from an external XT Series to Scopia® Management). A port is outbound if its destination is receiving data from a source protected by the firewall (for example, data sent from Scopia® Management to an external XT Series). Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 27 Figure 17: Inbound and outbound ports for the XT Series Depending on the location of the XT Series, a unidirectional port might be inbound to the organization or outbound from the organization. For example: • Port 161 is an outbound port from Scopia® Management or an SNMP management server to an external XT Series. • Port 162 is an inbound port from an external XT Series to Scopia® Management or an SNMP management server. Important: On stateful firewalls, ports are left open to response data for an allocated period of time after the initial request. For unidirectional ports, this response is the only data allowed through in the opposite direction. On bidirectional ports, data can be initiated and sent through in both directions. If you are opening unidirectional ports for the XT Series, see Table 6: Unidirectional ports to open for the XT Series on page 29. You need to determine if they are inbound or outbound depending on the source and destination. If you are opening bidirectional ports for the XT Series, see Table 7: Bidirectional ports to open for the XT Series on page 32.

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 32 Configuring the TCP or UDP Port Range on the Avaya Scopia® XT Series About this task You can configure the TCP or UDP port range by setting the base port, which is the lower end of the port range (if, for example, port 3230 is busy). The Avaya Scopia® XT Series uses dynamic TCP ports 3230-3250 for the following: • H.225.0: An H.323 protocol that specifies the messages and procedures used by gatekeepers to set up calls. • Q.931: A telephony protocol used for establishing and terminating the connection in H.323 calls. • H.245: A Control Protocol used for multimedia communication; enables transferring information about the device capabilities, as well as opening/closing the logical channels that carry media streams. • SIP: A signaling protocol used for creating, modifying, or terminating multimedia connections between two or more participants. The Avaya Scopia® XT Series uses dynamic UDP ports 3230-3248 for enabling real-time H.323 and SIP media, including audio, video, and H.224/data (RTP), and media control (RTCP). Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the port settings. From the XT Series web interface, select Administrator Settings > Networks > Preferences > Dynamic Ports. From the endpoint's main menu, select Configure > Advanced > Networks > Preferences > Dynamic Ports.

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Planning the Topology of the Avaya Scopia® XT Series Deployment | 34 Chapter 4 | Setting Up the XT Series Hardware These sections describe how to connect the XT Series to the network and other hardware components like monitors, cameras and microphones. Navigation • Planning the Optimal Room Setup on page 35 • Connecting Avaya Scopia® XT Series to the Network on page 38 • Connecting Monitors to the XT Series on page 38 • Connecting Cameras or DVD players on page 39 • Connecting Microphones and Speakers to the XT Series on page 48 • Connecting a Computer to the XT Series on page 54 Planning the Optimal Room Setup Follow the recommended guidelines described in this section when setting up a room with an Avaya Scopia® XT Series endpoint. Figure 19: Optimal Room Setup • Walls and furniture Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 35 Choose a plain neutral wall color. Avoid white walls as they increase the back light, causing cameras to reduce exposure and introducing a silhouetting effect. Avoid glass walls, or patterned and textured walls as they may cause visual disturbances. The room should be well and uniformly lit, with a brightness of at least 300 lux, avoiding a mixture of natural and artificial light. Light should come from the top of the conference table, the front and the rear (for depth of field). If the only light is from the ceiling, it should be gentle light and generate as little heat as possible. Use heavy curtains with a neutral color and install carpets to reduce noise interference from resonance with hard surfaces in the room. The room should be air-conditioned to avoid the XT Codec Unit activating its fan. • Camera positions Ensure the camera's view captures all the seats in the room (Figure 20: Camera scope covers all seats on page 36). Figure 20: Camera scope covers all seats All cameras should be at a height to ensure eye contact between local and remote participants. Try positioning the camera between the two monitors either directly above or below them, at a distance which captures all the seats. Caution: Do not place the camera on top of the XT Codec Unit. It can cause the system to overheat. Place chairs so that you and other participants appear in full frame of the cameras, in the middle of the monitors. For larger rooms, a single XT Series can manage more than one camera. For more information, see Connecting Cameras or DVD players on page 39. • Microphone positions Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 36 Place the Microphone Pod at the center of the table, in front of the participants. If you deploy the One-way Microphone Pod, note it has a limited three meter 180° range, so be sure to place all participants on one side of the microphone. The Three-way Microphone Pod picks up sound up to three meters away at all angles (360°). Figure 21: Placing the Microphone Pods Position the Microphone Pod as far as possible from loudspeakers and other noise sources. Do not place paper or other objects in front of the Microphone Pod. For large conference rooms, you can deploy two Microphone Pods, distributed evenly on the table. In very large rooms, consider an audio mixer to add as many microphones as needed. For more information, see Choosing a Microphone for Your XT Series on page 48. • Position of the XT Codec Unit Place the XT Codec Unit on a horizontal surface which stands firmly on its base. The surface must be dry and free of dust, oil and other residues. Position the XT Codec Unit and the camera so that their front panel infra-red (IR) sensors are visible by someone holding the XT Remote Control Unit. If the XT Codec Unit is in a cabinet, the XT Remote Control Unit sends to the main camera's sensor which relays to the XT Codec Unit. Ensure the infra-red sensors do not face sunlight or inverter fluorescent lamps. Place the XT Codec Unit anywhere within a five meters reach of the camera cables. Leave enough space around the XT Codec Unit for air circulation and for connecting cables easily. • Configuring the monitors Configure the monitors while the cameras are in self-view mode to ensure the correct levels of contract, brightness and sharpness. If the monitor has visual preset modes, choose Cinema or Movie as the best choice for videoconferencing.

Connecting Avaya Scopia® XT Series to the Network About this task Your Avaya Scopia® XT Series comes with two network ports (dual-NIC), where each is a GLAN or gigabit LAN port, operating at speeds of 10 or 100 or 1000 megabits per second (Mbps). Connect the network cable to the GLAN1 If required, you can enable GLAN2 Enabling the License on page 69). port. with a license to use both network ports (see Registering and For example, a small business can use the XT Series as a firewall traversal system (see Planning NAT and Firewall Traversal with Avaya Scopia® XT Series on page 21), where the XT Series hosts a call on its built-in MCU, and endpoints from both the public and private networks can access the same videoconference. Connect one network port to the public network and the other to the private network. Another example of dual-NIC usage is when a large organization routes video on a higher performance network, while routing the API control of the XT Series on another network.

Configure the cameras' settings (see Configuring Cameras on page 87.) If required, connect a DVD or HDMI media player to a port on the Scopia® XT Camera Switch. Connecting an Additional PTZ Camera Directly About this task You can connect an additional PTZ (pan, tilt and zoom) camera to the XT Series for large room setups when one camera does not cover enough area. You can connect it directly to the DVI port on the XT Codec Unit, as detailed in this section, or if you have an XT5000, you can connect it via the Scopia® XT Camera Switch (purchased separately) which keeps the DVI port free to add a computer or DVD player (see Connecting Multiple HDMI Devices or Cameras (XT5000 Series only) on page 41). The additional PTZ camera kit contains the camera itself, remote control, power supply, HDMI to DVI adapter, five-meter DVI-HDMI cable, and a ceiling mount kit. It also includes a 10-meter VISCA cross cable, enabling you to control both cameras with the same XT Remote Control Unit on the XT5000 Series only, by connecting a VISCA cross cable between the cameras. This disables the extra remote control. VISCA is a standard protocol to control PTZ cameras. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 45 Figure 33: Connecting an additional camera directly to the DVI port on the XT Series Important: Connecting cameras with a VISCA cable requires that both are exactly the same model. Before you begin For larger room setups, if you need a longer HDMI cable than the supplied five-meter DVI-HDMI cable, be sure to add HDMI repeaters. For 1080p at 60fps, add a repeater every five meters. For 1080p at 30fps or 720p at 60fps, add a repeater every 10 meters. Compatible HDMI repeaters are listed in ThirdParty Accessories for Avaya Scopia® XT Series. To control both cameras of the same model using one XT Remote Control Unit (on the XT5000 Series only), use the supplied 10-meter VISCA cross cable, or for large room setups, buy a longer third-party cable, or create your own. The RS232 cable should be up to 15-20 meters long, where both ends have an 8-pin mini-DIN male connector. To create your own cable, connect the pins as shown in Figure 32: Creating your own long VISCA cross cable on page 46. Figure 32: Creating your own long VISCA cross cable Procedure 1. Remove the camera stabilizing cartons, to avoid damage to the system. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 46 Caution: Do not place the camera on top of the XT Codec Unit. It can cause the system to overheat. 2. Verify the SYSTEM SELECT switch on the back panel of the new camera is set to 7. 3. Connect the DVI port on the camera to the DVI connector on the XT Codec Unit (Figure 33: Connecting an additional camera directly to the DVI port on the XT Series on page 46). If you connect a camera to the DVI input, the system manages it as PC content. 4. Connect the power supply cable to the DC IN connector on the camera. 5. Plug the power supply cable into a power outlet. 6. (Optional for XT5000 Series only) To control the extra camera using the same XT Remote Control Unit, connect one end of the crossed VISCA control cable to the additional camera's IN (RS-232C) connector. Then connect the other end to the main camera's OUT (RS-232C) connector (Figure 33: Connecting an additional camera directly to the DVI port on the XT Series on page 46). 7. Apply power to the camera. Connecting a DVD or Blu-ray Player or Other Analog Video Equipment About this task You can add a DVD or Blu-ray player to the Avaya Scopia® XT Series to share its content during a videoconference by connecting it to the camera or DVI ports on the XT Codec Unit (see Figure 34: Connecting a DVD player or digital-analog converter on page 47). Figure 34: Connecting a DVD player or digital-analog converter You can also add an analog camera or other analog video equipment by connecting it to an analogdigital converter which, in turn, is connected to the same camera or DVI ports on the XT Codec Unit (see Figure 34: Connecting a DVD player or digital-analog converter on page 47). For information on the converters tested with the XT Series, see Third-Party Accessories for Avaya Scopia® XT Series. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 47 The XT Series supports digital content protection. If the XT Codec Unit detects that non-compliant devices are attached to one of the HD CAM inputs, the video is locked. • You can only view digitally protected content on a device that supports High-bandwidth Digital Content Protection (HDCP). • You cannot view digitally protected content on a device that copies HDCP content. • You cannot send digitally protected content to non-HDCP devices. Connecting Microphones and Speakers to the XT Series These sections describe how to connect audio equipment, such as the XT Digital Microphone Array Pod, to the XT Codec Unit: Navigation • Choosing a Microphone for Your XT Series on page 48 • Connecting a Microphone to the XT Series on page 51 • Connecting Headphones or an Amplifier with Loudspeakers on page 52 Choosing a Microphone for Your XT Series This section provides an overview of the different types of microphones which are shipped with the various models in the Avaya Scopia® XT Series. You can add more microphones to your XT Series depending on the room setup. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 48 Figure 35: Choosing the microphone for your XT Series To determine the best microphone positioning, see Planning the Optimal Room Setup on page 35. When deciding on the microphone best suited for the meeting room, consider the following factors: • A larger room requires more microphones. Position the microphones to ensure all participants are within range. • A digital microphone brings higher quality sound, and are usually connected via optical cables which can be deployed over longer distances than analog (copper) wires. • For more complex audio setups, you can connect the XT Series to an audio mixer. • The XT Codec Unit uses the same audio in port for third-party digital microphone, analog microphones, line input, and computer audio, so you must choose between them. You can free this port when you use the digital three-way XT Digital Microphone Array Pod, which uses its own microphone port, or by using an audio mixer. There are several connections available to input audio to the XT Series: • The dedicated microphone port is for the digital Three-way Microphone Pod. The XT5000 Series can support two of these microphones daisy-chained. • The USB port is used for USB headsets, or for a USB camera with a built-in microphone (lower USB only). • The audio input port is for: – The analog One-way Microphone Pod or any other analog microphone with a 3.5mm jack. – A third-party digital microphone with a mini-TOSlink connector. – Audio mixers like those from Clear One. An audio mixer connects multiple microphones (or other audio inputs) to generate a single audio stream. – A computer audio-out connection or line audio connection. Table 8: Types of microphones on page 50 describes the most common types of microphones used with an Avaya Scopia® XT Series.

To determine the best microphone positioning, see Planning the Optimal Room Setup on page 35. More complex setups, like setting up an auditorium or mixing different types of microphones, may require an audio mixer (for example Clear One mixers). An audio mixer connects multiple microphones (or other audio inputs) to generate a single audio stream. Using an audio mixer requires you disable echo-cancellation on the XT Series (see Configuring Microphones on page 90) and then enable it either on the audio mixer, or (ideally) on each microphone. The audio mixer must have either an analog audio I/O (mini jack 3.5”) connector or a digital optical (mini-TOSlink) connector. The Scopia® XT Executive uses the microphone embedded in the camera by default. If you connect an additional microphone, the embedded microphone is disabled. Procedure 1. Connect a microphone to the XT Codec Unit as follows: • The dedicated microphone port is for the digital Three-way Microphone Pod. The XT5000 Series can support two of these microphones daisy-chained. • The USB port is used for USB headsets, or for a USB camera with a built-in microphone (lower USB only). • The audio input port is for: – The analog One-way Microphone Pod or any other analog microphone with a 3.5mm jack. – A third-party digital microphone with a mini-TOSlink connector. – Audio mixers like those from Clear One. An audio mixer connects multiple microphones (or other audio inputs) to generate a single audio stream. – A computer audio-out connection or line audio connection.

Audio mixer Disable the XT Series built-in echo cancellation (see Configuring Microphones on page 90). You then cancel the echo either in the audio mixer's settings, or (ideally) on each microphone. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 52 Connecting Headphones or an Amplifier with Loudspeakers About this task By default, you hear the sound of your Avaya Scopia® XT Series from the monitors' speakers. The monitors are connected to the XT Codec Unit using HDMI, which sends both audio and video. To boost sound beyond the monitors' own speakers, you can add an amplifier and loudspeakers by connecting them to the analog or digital audio output port of the XT Codec Unit. Alternatively, if you want to route the audio to headphones, for example when using the Scopia® XT Executive, you can connect headphones to the monitor's audio port or the lower USB port so it cuts off the monitor's speakers and routes sound to the headphones only. Before you begin If connecting an amplifier, verify you have a shielded stereo audio cable with a 3.5mm stereo audio plug. Procedure 1. To boost sound, connect an amplifier with speakers directly to the audio output port the XT Series. on Figure 38: Connecting external amplifier/speakers to the XT Series 2. To connect headphones to replace the monitor's speakers, connect headphones to the audio output of the monitor. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Setting Up the XT Series Hardware | 53 Figure 39: Connecting headphones to the XT Series Alternatively, attach a USB headset to the USB port on the XT Codec Unit (see Choosing a Microphone for Your XT Series on page 48). Connecting a Computer to the XT Series About this task Connect a computer to share a presentation or other content during a call. You connect the video separately from the audio. The computer video is routed to the DVI port on the XT Codec Unit, while the audio is routed to the audio-in port. When you share a computer's sound during a call, remote participants hear the computer's audio output as well as the audio from the Microphone Pod. However, analog microphones like the one-way Microphone Pod use the same audio-in port as a connected computer, so to use both at the same time, connect them via an audio mixer (see Connecting a Microphone to the XT Series on page 51). On the Scopia® XT Executive, your computer content is automatically displayed on the monitor, but only ever shared when you manually choose to do so. When you receive an incoming call, it automatically displays the XT Series menus to easily allow you accept or reject the call, and your local camera displays your video on the monitor. Procedure 1. If your computer has a DVI port, connect it to the DVI port on the XT Codec Unit. Alternatively, use the supplied DVI-VGA adapter to connect a VGA cable from the adapter to the computer's VGA port.

Registering the XT Series to a SIP Server About this task This section explains how to register your XT Series to the SIP Registrar and how to configure the SIP Proxy connection. The XT Series can function in a SIP environment, where aliases are managed by SIP servers, not gatekeepers. You can dial an endpoint by entering its alias like 1234 or joe_smith, rather than remembering its IP address, where the SIP server routes the call correctly. To do this, the SIP server must register all endpoints to maintain the mapping list of aliases and endpoints to successfully route calls. If your SIP server is Cisco UCM or a BroadSoft proxy server, you cannot send videoconference layouts alongside a computer presentation (dual video). You either send shared content or the video. For the BroadSoft proxy server, controlling remote cameras is also not supported (H.224 is disabled). Deployment Guide for Avaya Scopia® XT Series Version 8.3 Controlling the XT Series | 64 Before you begin Verify that you have the following information about your SIP environment: • The DNS names or IP addresses of the SIP Proxy and SIP Registrar. • The transport protocol and port used in your SIP environment. • (Optional) The model of the SIP Proxy. • For the SIP infrastructure that requires a SIP user authentication, credentials for authenticating XT Series to the SIP Proxy and SIP Registrar.

The system supports working with dynamic addresses (DHCP) or fixed addresses, either in IPv4 only, or it can work in both IPv4 and IPv6, where even media streams in the same videoconference can be a mixture of IPv4 and IPv6. However, you can only use IPv4 for when sending commands via HTTP, SNMP, or AT commands. In some XT Series models, activating the second network port GLAN2 (dual-NIC) requires an additional license (see Registering and Enabling the License on page 69). Both small businesses and large enterprises may require both network ports (see Connecting Avaya Scopia® XT Series to the Network on page 38). If you deployed TLS with a security certificate for this device, a change in the IP address requires creating a new certificate (see Securing Connections to the XT Series Using TLS on page 142).

Configuring Advanced Network Connectivity About this task This section describes how to determine which of the two network ports is the first choice to communicate on a call, and to configure advanced properties of the network connections in each network port, including the network speed and packet size (MTU). To avoid connectivity issues, match these settings to the equivalent settings in the network. In addition, if your large network is split into virtual sub-networks to limit the range of broadcasts, known as VLANs, and your network components support 802.1q compliant VLAN tagging, you can assign a VLAN ID to tag the XT Series as belonging to a specific VLAN. You can also configure network security authentication to be 802.1x compliant, where it sends a username and password to your 802.1x authenticator, which verifies the login with the authentication server. (dual-NIC) requires an In some XT Series models, activating the second network port GLAN2 additional license (see Registering and Enabling the License on page 69).

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 102 Table 26: Configuring network connectivity Field Name MTU Setting The MTU, or Maximum Transmission Unit, is the maximum size of data packets sent around your network. This value must remain consistent for all network components, including servers like the MCU and Scopia® Desktop server, endpoints like XT Series and other network devices like LDAP servers and network routers. If you or a remote endpoint transmit at a larger MTU size, packets are dropped or fragmented. To avoid packet loss or fragmentation, ensure all network components use the same MTU size. The default MTU size is 1360. For IPv4, set the MTU between 576-1500. For IPv6, set it between 1280-1500. Speed/Duplex mode Set the speed and transition mode as follows: • Automatic: The XT Series selects the speed and duplex mode. We recommend this default mode. • Auto - up to 100/Full, Auto - up to 100/Half, Auto - up to 10/Full, Auto - up to 10/Half: Semi-automatic modes with a specified maximum. • Manual: Configure the speed and duplex mode manually for your network and the remote endpoints' settings.

User Name, Password Enter the 802.1x username and password. Configuring NAT and Firewall Traversal About this task Avaya Scopia® XT Series fully supports NAT and firewall traversal, enabling you to place it behind a NAT router or firewall and connect with other endpoints seamlessly. If an XT Series located inside your network hosts a call on its built-in MCU, other endpoints must contact the host unit by dialing its IP address. However, when sitting behind a NAT or firewall, a device can have an internal IP address which cannot be reached from outside the network. This poses a problem for endpoints located outside the network to find the correct IP address to dial. There are several ways to resolve this: • (Recommended) Contact a STUN public server to return your IP address as it looks from outside the network, and then send this public IP address to all endpoints you invite to the meeting. This is known as STUN auto-discovery. This also works for HTTP public servers. • Use a dedicated firewall traversal solution like the Avaya Scopia® PathFinder server and set it as your gatekeeper (see Configuring Advanced Gatekeeper Settings on page 107). • You can manually set a static public IP address of the unit, and configure your firewall and NAT to ensure this is reflected externally outside the network. For more information on each of these topologies, see Planning NAT and Firewall Traversal with Avaya Scopia® XT Series on page 21. When traversing firewalls, remember to set the firewall ports as detailed in Configuring the TCP or UDP Port Range on the Avaya Scopia® XT Series on page 32. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the firewall and NAT traversal settings. From the XT Series web interface, select Administrator Settings > Networks > Preferences > NAT. From the endpoint's main menu, select Configure > Advanced > Networks > Preferences > NAT.

Table 29: Configuring NAT-related settings Field Name Description NAT Traversal Select to allow the system to be located behind a firewall/NAT. Set to No if the system has a public IP address. NAT Discovery Enter the method used for the XT Series to discover its public IP address: • HTTP discovery uses an Avaya HTTP server to return the public IP address. The endpoint must be directly connected to the internet. • Manual lets you set the public IP address manually in the Public IP Address field. • (Recommended) STUN autodiscovery uses a public STUN server to return the unit's public IP address. If you choose this, enter the Server and Port of the STUN server. Refresh Time (sec) Enter the number of seconds to open a pinhole through the firewall. Also used by H.460 as TTL (Time To Live) of registration requests. Keepalive Ensures the connection is kept open by sending periodic pings to the remote units. 3. From the web interface only, select Save. Defining QoS Priority of Types of Network Traffic About this task Quality of Service (QoS) determines the priorities of different types of network traffic (audio, video and control/signaling), so in poor network conditions, prioritized traffic is still fully transmitted. For example, Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 105 you can set a higher priority to audio packets, so that when there is an issue with packet loss, audio quality is maintained over video. Important: It is essential that QoS settings are defined with identical values on this device and all network components, including Scopia® Solution components and your generic network components like switches and routers. Only create custom QoS settings if the rest of your network has the same settings. You can set the relative priorities of each type of data type, either by setting a custom priority value, known as differentiated service or DiffServe, or by assigning a ranking and type of service (TOS) to each type of data. Choose the QoS method used by the other network components in your organization, to match their values exactly. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the QoS settings. From the XT Series web interface, select Administrator Settings > Networks > Preferences > QoS. From the endpoint's main menu, select Configure > Advanced > Networks > Preferences > QoS. Figure 80: Configuring QoS settings 2. Set the fields as described in Table 30: Configuring QoS settings on page 107. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 106 Table 30: Configuring QoS settings Field Name Use QoS Description Select whether to enable or disable QoS. If you set Use QoS to Yes, you provide different priority to different data stream, or guarantee a certain level of performance to a data stream. In particular, you may choose between Precedence/TOS and Differentiated Service. Quality of service Choose to set the priorities by entering a custom numeric value, or enter a relative priority ranking. These are the two methods used by network components like routers or switches to implement their QoS settings: • Select DiffServe, short for Differentiated Service, if your network components set a custom priority value for each type of data. • Choose Precedence/TOS if your network components define QoS as a precedence ranking and a designated type of service (TOS) for each type of data. Audio, Video, Data, Signal Set the value for each type of data, according to your choice in the Quality of Service field. DiffServe Enter the custom priority value, also known as differentiated service or DiffServe, if QoS is implemented like this in your other network components. The values must be identical throughout your network, and for all remote endpoints connecting in videoconferences. TOS and Precedence Enter the type of service, alongside the precedence (priority ranking) of each type of data, identical to the settings of all other network components, and any remote endpoints connecting in a videoconference. 3. From the web interface only, select Save. Configuring Advanced Gatekeeper Settings About this task As part of H.323 network setup, the Avaya Scopia® XT Series must be registered to a gatekeeper, like Avaya Scopia® ECS Gatekeeper. A gatekeeper routes audio and video H.323 calls by resolving dial strings (H.323 alias or URI) into the IP address of an endpoint, and handles the initial connection of calls. For example, you can dial 1234 or joesmith and the gatekeeper routes the call correctly. To do this, the gatekeeper must register all endpoints to maintain the mapping list of aliases and endpoints to successfully route calls. It also registers gateways like an ISDN gateway or Scopia® Video Gateway, so it can route calls to a non-H.323 device. Registration with a gatekeeper may happen every time the endpoint is switched on, or after a set period. You can also secure your connection with the gatekeeper by enabling authentication. You can enter a special username and password in both the endpoint and the gatekeeper as a shared secret, which is used to authenticate the identities of the gatekeeper and endpoint.

Setting Call Bandwidth in XT Series About this task You can set the maximum bandwidth used by the Avaya Scopia® XT Series when participating in a meeting, measured as the maximum bitrate. Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to ensure the video is constantly updated, thereby maintaining smooth motion. If you lower the bitrate, you lower the quality of the video. In some cases, you can select a lower bitrate without noticing a significant drop in video quality; for example during a presentation or when a lecturer is speaking and there is very little motion. In video recordings, the bitrate determines the file size for each minute of recording. Bitrate is often measured in kilobits per second (kbps). The relationship between bandwidth and resolution dramatically changes when your call uses H.264 High Profile. H.264 High Profile is a standard for compressing video by up to 25% over the H.264 Baseline Profile, enabling high definition calls to be held over lower call speeds. It requires both sides of the transmission (sending and receiving endpoints) to support this protocol. If you change the video quality setting to Sharpness, it can slightly change the bandwidth required to maintain the same resolution. To change this setting, see Resolving Lip Sync Problem on page 169.

Setting a Time Limit for Videoconferences About this task Set a time limit for videoconferences to alert users that the time allocated for the meeting is about to end, and to end videoconferences that were left open. Once you set a time limit, an alert appears during the meeting when the time limit is reached. The user can then decide to disconnect from the videoconference, postpone the reminder and extend the meeting for another hour, or remove the time limit from this meeting. The meeting automatically closes if there is no response to the alert after 30 seconds. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1.

Configuring Advanced Sound (Audio Output) Settings About this task In most cases, the Avaya Scopia® XT Series sound output is transparent and works with the default settings. However, for complex room setups, the XT Series allows you to carefully merge different audio signals into audio tracks, and then route each track to any audio output, like a monitor's speakers. Merging all inputs and outputs into one sound stream, or track, creates echos and audio feedback loops. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 114 Figure 86: Echo or feedback loops to be avoided Therefore the XT Series handles audio in two separate tracks. Each track can combine multiple inputs into one sound stream, and routes it to one of the audio outputs available (Figure 87: Example of merging audio into two tracks on page 116). In the illustrated example, the room's microphones are not routed to the monitor's speakers, to avoid echo. Instead, the sound of other participants and the computer audio is routed to the monitor's speakers, while a video recorder would normally need to record both sides of the conversation, both room microphones and the sound of other participants. You may also want to record computer audio shared in the meeting. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 115 Figure 87: Example of merging audio into two tracks Figure 87: Example of merging audio into two tracks on page 116 also illustrates how the same audio source (like computer audio or remote sound) can be routed to both tracks. However an output device (like the monitor speakers) can only receive the merged sound of one of the tracks. This restriction simplifies the possible routing scenarios, making this advanced setup easier to manage. For more information on connecting the microphones and speakers, see Connecting Microphones and Speakers to the XT Series on page 48. This section details how to route any audio input or output to Track 1 or Track 2. Each output can only broadcast one track. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the audio output track settings. From the XT Series web interface, select Administrator settings > I/O connections > Audio - Outputs > Tracks. From the endpoint's main menu, select Configure > Advanced > I/O connections > Audio - Outputs > Tracks.

Configuring Advanced Echo Cancellation on External Microphones About this task The Avaya Scopia® XT Series has its own built-in echo cancellation for external microphones (or other audio input) without an audio mixer. You can hear an echo when a remote endpoint's external speaker (not headphones) picks up your voice in addition to their own audio, and re-broadcasts your own audio back to you and others in the meeting. Typically, you use the echo cancellation's default settings. However, you may need to modify some of these settings if your room setup is causing distortions in your audio input, such as: • Other participants hear a lot of background noise from your room • Other participants hear breaks in your audio • Other participants notice a delay in your audio relative to your video • Unclear audio resulting from distortions in noise. These issues can be caused by many factors, such as the shape of your room, the position of speakers and microphones, or the surface texture of furniture. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Enable the XT Series's built-in echo cancellation on the relevant microphone or other audio input (see Configuring Microphones on page 90). Important: You cannot use the built-in echo cancellation on an audio mixer. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 120 Procedure 1. Access the XT Series's echo cancellation settings. From the XT Series web interface, select Administrator settings > I/O connections > Echo Canceller. From the endpoint's main menu, select Configure > Advanced > I/O connections > Echo Canceller. Figure 91: Configuring echo cancellation 2. Set the fields as required. Table 38: Configuring echo cancellation settings Field Name AGC Description Enables/disables AGC. Automatic Gain Control (AGC) smooths audio signals through normalization, by lowering sounds which are too strong and strengthening sounds which are too weak. Typically, you enable AGC for optimal audio. However, you may want to disable it if your microphone is strengthening the sound of background noise, mistaking it for your voice. Noise reduction Enables/disables reduction of background noise in a conference room (like coughing, paper rustling, or the hum of an air conditioning system). Typically, you enable Noise reduction for optimal audio. However, you may want to disable it some voices are filtered out as background noise, which causes breaks in the audio. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 121 Field Name Audio delay automatic estimation Description An HDMI monitor might cause a delay in the audio, causing an echo. Set this field to Yes to improve its echo cancellation performance automatically. We recommend this setting when you connect a new monitor to the XT Series. If you set this field to No, you can generate the audio delay manually and train the echo cancellation to use the resulting audio for better performance. For details, see Cancelling the Echo on HDMI Monitors on page 162. Audio delay Select Yes to use the estimated audio delay. Typically, you enable Audio delay for optimal audio. However, you may want to disable it if your room has a strong echo that creates a reverberating effect, which may produce false results when estimating the audio delay. 3.

Configuring XT Series to use LDAP Directory About this task This procedure describes how to manage the contacts of your endpoint using different types of LDAP servers. All are accessed using the H.350 protocol, which enhances the LDAP standard to include video endpoint information. You can define up to 100 LDAP servers in the XT Series. Select one from the Server field in the Contacts page to view its contacts (Figure 92: Viewing and editing contacts in Local LDAP server on page 122). Figure 92: Viewing and editing contacts in Local LDAP server You can define the following types of LDAP servers: • The local built-in LDAP server Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 122 There is only one local LDAP server which cannot be removed, and has a password. You can edit, create or delete local contact details there (Figure 92: Viewing and editing contacts in Local LDAP server on page 122). • A remote XT Series's built-in LDAP server The contacts are read-only when browsing a remote XT Series's LDAP server. You can access more than one of these LDAP servers, where each requires only the IP address of the remote endpoint and its LDAP password. • Scopia® Management's built-in LDAP server The contacts of this server are read-only from the endpoint. You can define more than one such server, specifying each IP address, port, and its LDAP username and password. The resulting contact list is filtered to show only users registered to an endpoint. Important: If the Scopia® Management LDAP server has a Root DN defined, you must specify the RootDN field when accessing that LDAP server. • A third-party LDAP server, such as Microsoft Active Directory The contacts of a third party LDAP are read-only from the endpoint. The LDAP tree must have the following specific structure and naming conventions: – The Root DN must be defined. For example, dc=company, dc=com. – All users (inetOrgPerson entities) must be located under an organizational unit (ou) in the LDAP tree. For example, ou=people. – All endpoints (commObject entities) must be listed under an organizational unit called h323Identity if they are to work with H.323, and SIPIdentity if they are to work as SIP endpoints. Since the XT Series works both as an H.323 and a SIP endpoint, all XT Series commObjects should be listed under both organizational units. – Each endpoint is represented by a commObject with its commUniqueId. Each commObject contains the details of accessing this endpoint, and the user associated with it. Define the following fields: Table 39: commObject fields Field Value Comments objectClass commObject Use this exact value objectClass h323Identity Use this exact value commOwner uid=,ou=people,dc=compan The user ID associated y,dc=com with this endpoint h323IdentityEndpointType Terminal h323IdentitytransportID h323IdentitytransportDigits Use this exact value for H.323 endpoints only At least one of these fields must be defined for an H.323 endpoint. h323IdentitytransportNumber h323Identityh323-ID SIPIdentitySIPURI Deployment Guide for Avaya Scopia® XT Series Version 8.3 SIP endpoints only. Advanced Configuration of the XT Series | 123 – Each user (inetOrgPerson entity) must have its commURI field pointing to the user's endpoint (commObject ID). For example: ldap://123.456.789.012/ou=h323identity,dc=company,dc=com??sub?(commUniqueId=6) XT5000 where commUniqueId refers to the commObject ID. A centralized solution like Scopia® Management enables synchronizing the same list of contacts across all the endpoints in your organization, and has other benefits like remote centralized upgrading and backing up of all endpoints in your video network. You can configure the XT Series to use Scopia® Management as the LDAP directory also from the Avaya Scopia® Management administrator portal (for details, see the Administrator Guide for Avaya Scopia® Management). Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. If you are using Avaya Scopia® Management as the LDAP directory, you must associate LDAP contacts to video endpoints; otherwise these contacts are not displayed on the XT Series. Each LDAP contact on the XT Series can only be mapped to a maximum of ten video endpoints. Procedure 1. Access the LDAP settings.

You can only view and call these contacts from this endpoint. • Remote H.350 (generic) refers to a third-party LDAP server, such as Microsoft Active Directory. You can only view and call these contacts from this endpoint. Address Enter the LDAP server address. If you are using Scopia® Management as your LDAP directory, enter Scopia® Management's IP address. Port Enter the port used to connect to the LDAP server. The default port is 389. User Enter the username and password required to access the LDAP server. The format of the username is in the form of a Distinguished Name (DN). Some standard components of DN are: domain controller (dc), organizational unit (ou), common name (cn), country (c), state or province (st), locality (l), organization (o). Password The login to third party LDAP servers is via a Simple Bind LDAP v3 operation. When using the endpoint's local built-in LDAP server, you can modify the password here. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 125 Field Name Base Description Enter the root node of the LDAP tree under which all the contacts (inetOrgPerson entities) are defined. For example ou=people. This value is predefined when the LDAP server is an XT Series or Scopia® Management, and cannot be modified. Root DN For third party LDAP servers, enter the mandatory H.350 Root DN. For a Scopia® Management LDAP directory, if you defined the Root DN in Scopia® Management, enter it here.

Configuring Advanced DTMF Settings About this task This section details the advanced configuration of DTMF, a method used to send messages to other endpoints or network devices like gateways or MCUs. DTMF, or touch-tone, is the method of dialing on touch-tone phones, where each number is translated and transmitted as an audio tone. The DTMF format for a call is decided during call setup. There are several types of DTMF: • Inband DTMF is the most basic form of DTMF, which transmits audio sounds within the audio stream, heard by participants. • Out-of-band DTMF transmits messages outside the audio band, and are only converted to audio at the receiving end. H.323 has several methods of incorporating out-of-band DTMF: – User Input Indication (UII) is part of the H.245 standard, used in H.323 calls only. – RFC2833 is the standard method used in SIP calls. However, you have the option to use this method in H.323 calls as well, provided both endpoints support the standard within H.323. You can communicate with the Scopia® Elite MCU using any kind of DTMF to display menus and change layouts. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the IP settings. From the XT Series web interface, select Administrator Settings > Calls > Preferences > IP.

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 127 Setting Recording Preferences About this task You can record and playback meetings from a locally connected USB storage device, or record to the Scopia® Desktop Content Center server. This procedure describes how to configure your USB recording preferences, such as the video resolution and bitrate. This is useful, for example, to increase the time available for recording on your USB storage device. This may require a license, depending on your model. For more information, see Registering and Enabling the License on page 69. You can playback recordings from the local USB storage device either on the XT Series or using any standard media player. The system saves the file as an MP4, and records the video in H.264 format with audio in AAC-LC format. You cannot record locally to USB when encryption is enabled (see Enabling Encryption for Videoconferences on page 150). If you host the meeting on your built-in MCU, you can record either three remote endpoints if your license is MCU4, or six remote endpoints if your license is MCU9. Procedure 1. Access the recording settings. From the XT Series web interface, select Basic Settings > Recording > General. From the endpoint's main menu, select Configure > Recording.

Define the following recording settings: Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 128 Table 42: Configuring recording settings Field Description Enabled (Only in Configure > Advanced > Utilities > Recording) Select Yes to enable recording and playback from a local USB storage device. Resolution Select the video resolution of the recording. The frame rate is limited to 25fps. For best quality, use the default 1080p resolution, but use a lower value if your media player does not support higher resolutions. When you change the resolution, the system automatically selects the optimal bitrate for this resolution. Bit rate Select the bitrate to determine the file size of the recording. To use less space on your USB storage device, select a lower bitrate. For the best results, use the default value for your chosen resolution. Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to ensure the video is constantly updated, thereby maintaining smooth motion. If you lower the bitrate, you lower the quality of the video. In some cases, you can select a lower bitrate without noticing a significant drop in video quality; for example during a presentation or when a lecturer is speaking and there is very little motion. In video recordings, the bitrate determines the file size for each minute of recording. Bitrate is often measured in kilobits per second (kbps). To estimate the space you need for the recording, see Table 43: Typical file sizes based on the bitrate on page 129. You can see how much recording time is available on your USB storage device when you access the Recording menu (for details, see User Guide for Avaya Scopia® XT Series ). Audio Alert Select Yes to enable an audio message alert at the beginning of the videoconference, indicating to all participants that the meeting is being recorded.

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Advanced Configuration of the XT Series | 131 Remotely Controlling the XT Series with AT Commands About this task For complex room setups, you can remotely control your Avaya Scopia® XT Series from controllers like AMX, Creston or Extron devices which use a proprietary API known as AT commands. It has this name because while it is proprietary, it has a similar syntax to the standard modem AT commands, using ASCII characters to communicate messages. The XT Series can receive AT commands from its network connection to the controller's IP address over port 55003, or from its USB connection to the controller's serial port connected via a standard RS232 cable. You can use AT commands to control all functionality of the XT Series available in the endpoint or web interface. Before using this functionality, you must enable AT command management in the XT Series. You can restrict whether AT commands are allowed only over the RS232 cable or over the network connection, and you can also restrict the range of IP addresses allowed to control the unit. For more information on the supported AT commands, contact your local customer service representative. Before you begin Ensure you have the IP addresses and the subnet mask of the devices which remotely control the XT Series. If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. Procedure 1. Access the AT settings. From the XT Series web interface, select Administrator Settings > Utilities > Remote Access > AT Commands. From the endpoint's main menu, select Configure > Advanced > Utilities > Remote Access > AT Commands. Figure 100: Configuring AT commands 2. Set the fields as required.

Securing Connections to the XT Series Using TLS You can configure your video network devices, both Scopia® Solution and third-party, to support Transport Layer Security (TLS) for the SIP protocol. Important: Using encryption is subject to local regulation. In some countries it is restricted or limited for usage. For more information, consult your local reseller. TLS enables network devices to communicate securely using certificates, to provide authentication of the devices and encryption of the communication between them. To create a TLS certificate, you need to generate a certificate signing request (CSR) and send it to the certification authority (CA) for signing. A CA has its own certificate, known as the CA root certificate. When the CA signed certificate is ready, you upload it into the XT Series for which it was created, together with the CA root certificate. Once this is done, the component can authenticate itself and is ready for TLS connection. Each time a video network device starts the TLS communication session, it sends its own signed certificate together with the CA root certificate and requests the same certificates from the other devices to which it wants to connect. After both devices verify each other's identity, a secure TLS connection can be established. Exchanging certificates between devices is part of the TLS protocol; it happens in the background and is transparent to a user. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Securing your XT Series | 142 Figure 108: Establishing TLS connection The following set of procedures secure the connection between XT Series and other devices.

(Optional) If required by your organization's security policies, continue with Enabling Encryption for Videoconferences on page 150. Enabling Encryption for Videoconferences About this task The system can secure videoconference sessions via encrypted connections, in both point-to-point calls and videoconferences, as follows: • For SIP connections, you can encrypt the actual media of SIP connections via SRTP. Secure Real-time Transport Protocol (SRTP) adds security to the standard RTP protocol, which is used to send media (video and audio) between devices in SIP calls. It offers security with encryption, authentication and message integrity. The encryption uses a symmetric key generated at the start of the call, and being symmetric, the same key locks and unlocks the data. So to secure transmission of the symmetric key, it is sent safely during call setup using TLS. • For H.323 connections, encryption is enabled via H.235. H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream during meetings. Configure settings for securing calls as described in the procedure below. You can have up to three remote encrypted participants in a videoconference. Important: Using encryption is subject to local regulation. In some countries it is restricted or limited for usage. For more information, consult your local reseller. Before you begin If configuring from the endpoint, you must first enable advanced configuration, as described in Enabling Advanced Maintenance on the XT Series on page 95. To encrypt SIP calls using SRTP, you must also secure communication between your video network devices using TLS certificates and enable encryption (see Securing Connections to the XT Series Using Deployment Guide for Avaya Scopia® XT Series Version 8.3 Securing your XT Series | 150 TLS on page 142). If TLS is not enabled, only SIP calls to other XT Series endpoints are encrypted, using a proprietary encryption protocol. Procedure 1. Access the security settings. From the XT Series web interface, select Administrator Settings > Calls > Encryption. From the endpoint's main menu, select Configure > Advanced > Calls > Encryption. Figure 118: Encrypting calls from the web interface 2. Select Yes in the Enable encryption field. 3. Set the fields as described in Table 50: Configuring settings for securing calls on page 151.

Deployment Guide for Avaya Scopia® XT Series Version 8.3 Troubleshooting the Avaya Scopia® XT Series | 177 Glossary of Terms for Scopia® Solution 1080p See Full HD on page 182. 2CIF 2CIF describes a video resolution of 704 x 288 pixels (PAL) or 704 x 240 (NTSC). It is double the width of CIF, and is often found in CCTV products. 2SIF 2SIF describes a video resolution of 704 x 240 pixels (NTSC) or 704 x 288 (PAL). This is often adopted in IP security cameras. 4CIF 4CIF describes a video resolution of 704 x 576 pixels (PAL) or 704 x 480 (NTSC). It is four times the resolution of CIF and is most widespread as the standard analog TV resolution. 4SIF 4SIF describes a video resolution of 704 x 480 pixels (NTSC) or 704 x 576 (PAL). This is often adopted in IP security cameras. 720p See HD on page 185. AAC AAC is an audio codec which compresses sound but with better results than MP3. Alias An alias in H.323 represents the unique name of an endpoint. Instead of dialing an IP address to reach an endpoint, you can dial an alias, and the gatekeeper resolves it to an IP address. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 178 AGC (Automatic Gain Control) Automatic Gain Control (AGC) smooths audio signals through normalization, by lowering sounds which are too strong and strengthening sounds which are too weak. This is relevant with microphones situated at some distance from the speaker, like room systems. The result is a more consistent audio signal within the required range of volume. Auto-Attendant Auto-Attendant, also known as video IVR, offers quick access to meetings hosted on MCUs, via a set of visual menus. Participants can select menu options using standard DTMF tones (numeric keypad). AutoAttendant works with both H.323 and SIP endpoints. Balanced Microphone A balanced microphone uses a cable that is built to reduce noise and interference even when the cable is long. This reduces audio disruptions resulting from surrounding electromagnetic interference. BFCP (Binary Floor Control Protocol) BFCP is a protocol which coordinates shared videoconference features in SIP calls, often used by one participant at a time. For example, when sharing content to others in the meeting, one participant is designated as the presenter, and is granted the floor for presenting. All endpoints must be aware that the floor was granted to that participant and react appropriately. Bitrate Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to ensure the video is constantly updated, thereby maintaining smooth motion. If you lower the bitrate, you lower the quality of the video. In some cases, you can select a lower bitrate without noticing a significant drop in video quality; for example during a presentation or when a lecturer is speaking and there is very little motion. In video recordings, the bitrate determines the file size for each minute of recording. Bitrate is often measured in kilobits per second (kbps). Call Control See Signaling on page 193. Cascaded Videoconference A cascaded videoconference is a meeting distributed over more than one physical Scopia® Elite MCU, where a master MCU connects to one or more slave MCUs to create a single videoconference. It increases the meeting capacity by combining the resources of several MCUs. This can be especially useful for distributed deployments across several locations, reducing bandwidth usage. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 179 CIF CIF, or Common Intermediate Format, describes a video resolution of 352 × 288 pixels (PAL) or 352 x 240 (NTSC). This is sometimes referred to as Standard Definition (SD). Content Slider The Scopia® Content Slider stores the data already presented in the videoconference and makes it available for participants to view during the meeting. Continuous Presence Continuous presence enables viewing multiple participants of a videoconference at the same time, including the active speaker. This graphics-intensive work requires scaling and mixing the images together into one of the predefined video layouts. The range of video layouts depends on the type of media processing supported, typically located in the MCU. Control Control, or media control, sets up and manages the media of a call (its audio, video and data). Control messages include checking compatibility between endpoints, negotiating video and audio codecs, and other parameters like resolution, bitrate and frame rate. Control is communicated via H.245 in H.323 endpoints, or by SDP in SIP endpoints. Control occurs within the framework of an established call, after signaling. CP See Continuous Presence on page 180. Dedicated Endpoint A dedicated endpoint is a hardware endpoint for videoconferencing assigned to a single user. It is often referred to as a personal or executive endpoint, and serves as the main means of video communications for this user. For example, Scopia® XT Executive. It is listed in the organization's LDAP directory as associated exclusively with this user. Dial Plan A dial plan defines a way to route a call and to determine its characteristics. In traditional telephone networks, prefixes often denote geographic locations. In videoconferencing deployments, prefixes are also used to define the type and quality of a call. For example, dial 8 before a number for a lower bandwidth call, or 6 for an audio-only call, or 5 to route the call to a different branch. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 180 Dial Prefix A dial prefix is a number added at the beginning of a dial string to route it to the correct destination, or to determine the type of call. Dial prefixes are defined in the organization's dial plan. For example, dial 9 for an outside line, or dial 6 for an audio only call. Distributed Deployment A distributed deployment describes a deployment where the solution components are geographically distributed in more than one network location. DNS Server A DNS server is responsible for resolving domain names in your network by translating them into IP addresses. DTMF DTMF, or touch-tone, is the method of dialing on touch-tone phones, where each number is translated and transmitted as an audio tone. Dual Video Dual video is the transmitting of two video streams during a videoconference, one with the live video while the other is a shared data stream, like a presentation. Dynamic Video Layout The dynamic video layout is a meeting layout that switches dynamically to include the maximum number of participants it can display on the screen (up to 9 on the XT Series, or up to 28 on Scopia® Elite MCU). The largest image always shows the active speaker. E.164 E.164 is an address format for dialing an endpoint with a standard telephone numeric keypad, which only has numbers 0 - 9 and the symbols: * and #. Endpoint An endpoint is a tool through which people can participate in a videoconference. Its display enables you to see and hear others in the meeting, while its microphone and camera enable you to be seen and heard by others. Endpoints include dedicated endpoints, like Scopia® XT Executive, software endpoints Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 181 like Scopia® Desktop Client, mobile device endpoints like Scopia® Mobile, room systems like XT Series, and telepresence systems like Scopia® XT Telepresence. Endpoint Alias See Alias on page 178. FEC Forward Error Correction (FEC) is a proactive method of sending redundant information in the video stream to preempt quality degradation. FEC identifies the key frames in the video stream that should be protected by FEC. There are several variants of the FEC algorithm. The Reed-Solomon algorithm (FECRS) sends redundant packets per block of information, enabling the sender (like the Scopia® Elite MCU) to manage up to ten percent packet loss in the video stream with minimal impact on the smoothness and quality of the video. FECC Far End Camera Control (FECC) is a feature of endpoint cameras, where the camera can be controlled remotely by another endpoint in the call. Forward Error Correction See FEC on page 182. FPS See Frames Per Second on page 182. Frame Rate See Frames Per Second on page 182. Frames Per Second Frames Per Second (fps), also known as the frame rate, is a key measure in video quality, describing the number of image updates per second. The average human eye can register up to 50 frames per second. The higher the frame rate, the smoother the video. Full HD Full HD, or Full High Definition, also known as 1080p, describes a video resolution of 1920 x 1080 pixels. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 182 Full screen Video Layout The full screen view shows one video image. Typically, it displays the remote presentation, or, if there is no presentation, it displays the other meeting participant(s). Gatekeeper A gatekeeper routes audio and video H.323 calls by resolving dial strings (H.323 alias or URI) into the IP address of an endpoint, and handles the initial connection of calls. Gatekeepers also implement the dial plan of an organization by routing H.323 calls depending on their dial prefixes. Scopia® Management includes a built-in Avaya Scopia® Gatekeeper, while ECS is a standalone gatekeeper. Gateway A gateway is a component in a video solution which routes information between two subnets or acts as a translator between different protocols. For example, a gateway can route data between the headquarters and a partner site, or between two protocols like the TIP Gateway, or the Scopia® 100 Gateway. GLAN GLAN, or gigabit LAN, is the name of the network port on the XT Series. It is used on the XT Series to identify a 10/100/1000MBit ethernet port. H.225 H.225 is part of the set of H.323 protocols. It defines the messages and procedures used by gatekeepers to set up calls. H.235 H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream during meetings. H.239 H.239 is a widespread protocol used with H.323 endpoints, to define the additional media channel for data sharing (like presentations) alongside the videoconference, and ensures only one presenter at a time. H.243 H.243 is the protocol used with H.323 endpoints enabling them to remotely manage a videoconference. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 183 H.245 H.245 is the protocol used to negotiate call parameters between endpoints, and can control a remote endpoint from your local endpoint. It is part of the H.323 set of protocols. H.261 H.261 is an older protocol used to compress CIF and QCIF video resolutions. This protocol is not supported by the XT Series. H.263 H.263 is an older a protocol used to compress video. It is an enhancement to the H.261 protocol. H.264 H.264 is a widespread protocol used with SIP and H.323 endpoints, which defines video compression. Compression algorithms include 4x4 transforms and a basic motion comparison algorithm called Pslices. There are several profiles within H.264. The default profile is the H.264 Baseline Profile, but H.264 High Profile uses more sophisticated compression techniques. H.264 Baseline Profile See H.264 on page 184. H.264 High Profile H.264 High Profile is a standard for compressing video by up to 25% over the H.264 Baseline Profile, enabling high definition calls to be held over lower call speeds. It requires both sides of the transmission (sending and receiving endpoints) to support this protocol. H.264 High Profile uses compression algorithms like: • CABAC compression (Context-Based Adaptive Binary Arithmetic Coding) • 8x8 transforms which more effectively compress images containing areas of high correlation These compression algorithms demand higher computation requirements, which are offered with the dedicated hardware available in Scopia® Solution components. Using H.264 High Profile in videoconferencing requires that both the sender and receiver's endpoints support it. This is different from SVC which is an adaptive technology working to improve quality even when only one side supports the standard. H.320 H.320 is a protocol for defining videoconferencing over ISDN networks. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 184 H.323 H.323 is a widespread set of protocols governing the communication between endpoints in videoconferences and point-to-point calls. It defines the call signaling, control, media flow, and bandwidth regulation. H.323 Alias See Alias on page 178. H.350 H.350 is the protocol used to enhance LDAP user databases to add video endpoint information for users and groups. H.460 H.460 enhances the standard H.323 protocol to manage firewall/NAT traversal, employing ITU-T standards. Endpoints which are already H.460 compliant can communicate directly with the PathFinder server, where the endpoint acts as an H.460 client to the PathFinder server which acts as an H.460 server. HD A HD ready device describes its high definition resolution capabilities of 720p, a video resolution of 1280 x 720 pixels. High Availability High availability is a state where you ensure better service and less downtime by deploying additional servers. There are several strategies for achieving high availability, including deployment of redundant servers managed by load balancing systems. High Definition See HD on page 185. High Profile See H.264 High Profile on page 184. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 185 HTTPS HTTPS is the secured version of the standard web browser protocol HTTP. It secures communication between a web browser and a web server through authentication of the web site and encrypting communication between them. For example, you can use HTTPS to secure web browser access to the web interface of many Scopia® Solution products. Image Resolution See Resolution on page 191. kbps Kilobits per second (kbps) is the standard unit to measure bitrate, measuring the throughput of data communication between two devices. Since this counts the number of individual bits (ones or zeros), you must divide by eight to calculate the number of kilobytes per second (KBps). KBps Kilobytes per second (KBps) measures the bitrate in kilobytes per second, not kilobits, by dividing the number of kilobits by eight. Bitrate is normally quoted as kilobits per second (kbps) and then converted to kilobytes per second (KBps). Bitrate measures the throughput of data communication between two devices. LDAP LDAP is a widespread standard database format which stores network users. The format is hierarchical, where nodes are often represented as branch location > department > sub-department, or executives > managers > staff members. The database standard is employed by most user directories including Microsoft Active Directory, IBM Sametime and others. H.350 is an extension to the LDAP standard for the videoconferencing industry. Lecture Mode Scopia® Desktop's lecture mode allows the participant defined as the lecturer to see all the participants, while they see only the lecturer. All participants are muted except the lecturer, unless a participant asks permission to speak and is unmuted by the lecturer. This mode is tailored for distance learning, but you can also use it for other purposes like when an executive addresses employees during company-wide gatherings. Load balancer A load balancer groups together a set (or cluster) of servers to give them a single IP address, known as a virtual IP address. It distributes client service requests amongst a group of servers. It distributes loads Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 186 according to different criteria such as bandwidth, CPU usage, or cyclic (round robin). Load balancers are also known as application delivery controllers (ADC). Location A location is a physical space (building) or a network (subnet) where video devices can share a single set of addresses. A distributed deployment places these components in different locations, often connected via a VPN. Management Management refers to the administration messages sent between components of the Scopia® Solution as they manage and synchronize data between them. Management also includes front-end browser interfaces configuring server settings on the server. Management messages are usually transmitted via protocols like HTTP, SNMP, FTP or XML. For example, Scopia® Management uses management messages to monitor the activities of an MCU, or when it authorizes the MCU to allow a call to proceed. MBps Megabytes per second (MBps) is a unit of measure for the bitrate. The bitrate is normally quoted as kilobits per second (kbps) and then converted by dividing it by eight to reach the number of kilobytes per second (KBps) and then by a further 1000 to calculate the MBps. MCU An MCU, or Multipoint Control Unit, connects several endpoints to a single videoconference. It manages the audio mixing and creates the video layouts, adjusting the output to suit each endpoint's capabilities. MCU service See Meeting Type on page 188. Media Media refers to the live audio, video and shared data streams sent during a call. Presentation and Far end camera control (FECC) are examples of information carried on the data stream. Media is transmitted via the RTP and RTCP protocols in both SIP and H.323 calls. The parallel data stream of both live video and presentation, is known as dual video. Media Control See Control on page 180. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 187 Meeting Type Meeting types (also known as MCU services) are meeting templates which determine the core characteristics of a meeting. For example, they determine if the meeting is audio only or audio and video, they determine the default video layout, the type of encryption, PIN protection and many other features. You can invoke a meeting type by dialing its prefix in front of the meeting ID. Meeting types are created and stored in the MCU, with additional properties in Scopia® Management. Moderator A moderator has special rights in a videoconference, including blocking the sound and video of other participants, inviting new participants, disconnecting others, determining video layouts, and closing meetings. In Scopia® Desktop Client, an owner of a virtual room is the moderator when the room is protected by a PIN. Without this protection, any participant can assume moderator rights. MTU The MTU, or Maximum Transmission Unit, is the maximum size of data packets sent around your network. This value must remain consistent for all network components, including servers like the MCU and Scopia® Desktop server, endpoints like XT Series and other network devices like LDAP servers and network routers. Multicast Streaming Multicast streaming sends a videoconference to multiple viewers across a range of addresses, reducing network traffic significantly. Scopia® Desktop server multicasts to a single IP address, and streaming clients must tune in to this IP address to view the meeting. Multicasts require that routers, switches and other equipment know how to forward multicast traffic. Multi-Point A multi-point conference has more than two participants. Multi-tenant Service provider, or multi-tenant, deployments enable one installation to manage multiple organizations. All the organizations can reside as tenants within a single service provider deployment. For example, Scopia® Management can manage a separate set of users for each organization, separate local administrators, separate bandwidth policies etc. all within a single multi-tenant installation. NAT A NAT, or Network Address Translation device, translates external IP addresses to internal addresses housed in a private network. This enables a collection of devices like endpoints in a private network, each with their own internal IP address, can be represented publicly by a single, unique IP address. The Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 188 NAT translates between public and private addresses, enabling users toplace calls between public network users and private network users. NetSense NetSense is a proprietary Scopia® Solution technology which optimizes the video quality according to the available bandwidth to minimize packet loss. As the available bandwidth of a connection varies depending on data traffic, NetSense's sophisticated algorithm dynamically scans the video stream, and then reduces or improves the video resolution to maximize quality with the available bandwidth. Packet Loss Packet loss occurs when some of the data transmitted from one endpoint is not received by the other endpoint. This can be caused by narrow bandwidth connections or unreliable signal reception on wireless networks. PaP Video Layout The PaP (Picture and Picture) view shows up to three images of the same size. Phantom Power Microphones which use phantom power draw their electrical power from the same cable as the audio signal. For example, if your microphone is powered by a single cable, it serves both to power the microphone and transmit the audio data. Microphones which have two cables, one for sound and a separate power cable, do not use phantom power. PiP Video Layout The PiP (Picture In Picture) view shows a video image in the main screen, with an additional smaller image overlapping in the corner. Typically, a remote presentation is displayed in the main part of the screen, and the remote video is in the small image. If the remote endpoint does not show any content, the display shows the remote video in the main part of the screen, and the local presentation in the small image. Point-to-Point Point-to-point is a feature where only two endpoints communicate with each other without using MCU resources. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 189 PoP Video Layout The PoP (Picture out Picture) view shows up to three images of different size, presented side by side, where the image on the left is larger than the two smaller images on the right. Prefix See Dial Prefix on page 181. PTZ Camera A PTZ camera can pan to swivel horizontally, tilt to move vertically, and optically zoom to devote all the camera's pixels to one area of the image. For example, the XT Standard Camera is a PTZ camera with its own power supply and remote control, and uses powerful lenses to achieve superb visual quality. In contrast, fixed cameras like webcams only offer digital PTZ, where the zoom crops the camera image, displaying only a portion of the original, resulting in fewer pixels of the zoomed image, which effectively lowers the resolution. Fixed cameras also offer digital pan and tilt only after zooming, where you can pan up to the width or length of the original camera image. Q.931 Q.931 is a telephony protocol used to start and end the connection in H.323 calls. QCIF QCIF, or Quarter CIF, defines a video resolution of 176 × 144 pixels (PAL) or 176 x 120 (NTSC). It is often used in older mobile handsets (3G-324M) limited by screen resolution and processing power. Quality of Service (QoS) Quality of Service (QoS) determines the priorities of different types of network traffic (audio, video and control/signaling), so in poor network conditions, prioritized traffic is still fully transmitted. Recordings A recording of a videoconference can be played back at any time. Recordings include audio, video and shared data (if presented). In Scopia® Desktop, any participant with moderator rights can record a meeting. Users can access Scopia® Desktop recordings from the Scopia® Desktop web portal or using a web link to the recording on the portal. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 190 Redundancy Redundancy is a way to deploy a network component, in which you deploy extra units as 'spares', to be used as backups in case one of the components fails. Registrar A SIP Registrar manages the SIP domain by requiring that all SIP devices register their IP addresses with it. For example, once a SIP endpoint registers its IP address with the Registrar, it can place or receive calls with other registered endpoints. Resolution Resolution, or image/video resolution, is the number of pixels which make up an image frame in the video, measured as the number of horizontal pixels x the number of vertical pixels. Increasing resolution improves video quality but typically requires higher bandwidth and more computing power. Techniques like SVC, H.264 High Profile and FEC reduce bandwidth usage by compressing the data to a smaller footprint and compensating for packet loss. Restricted Mode Restricted mode is used for ISDN endpoints only, when the PBX and line uses a restricted form of communication, reserving the top 8k of each packet for control data only. If enabled, the bandwidth values on these lines are in multiples of 56kbps, instead of multiples of 64kbps. Room System A room system is a hardware videoconferencing endpoint installed in a physical conference room. Essential features include its camera's ability to PTZ (pan, tilt, zoom) to allow maximum flexibility of camera angles enabling participants to see all those in the meeting room or just one part of the room. RTP RTP or Real-time Transport Protocol is a network protocol which supports video and voice transmission over IP. It underpins most videoconferencing protocols today, including H.323, SIP and the streaming control protocol known as RTSP. The secured version of RTP is SRTP. RTCP Real-time Control Transport Protocol, used alongside RTP for sending statistical information about the media sent over RTP. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 191 RTSP RTSP or Real-Time Streaming Protocol controls the delivery of streamed live or playback video over IP, with functions like pause, fast forward and reverse. While the media itself is sent via RTP, these control functions are managed by RTSP Sampling Rate The sampling rate is a measure of the accuracy of the audio when it is digitized. To convert analog audio to digital, it must collect or sample the audio at specific intervals. As the rate of sampling increases, it raises audio quality. SBC A Session Border Controller (SBC) is a relay device between two different networks. It can be used in firewall/NAT traversal, protocol translations and load balancing. Scalability Scalability describes the ability to increase the capacity of a network device by adding another identical device (one or more) to your existing deployment. In contrast, a non-scalable solution would require replacing existing components to increase capacity. Scopia® Content Slider See Content Slider on page 180. SD Standard Definition (SD), is a term used to refer to video resolutions which are lower than HD. There is no consensus defining one video resolution for SD. Service Also known as MCU service. See Meeting Type on page 188. SIF SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288 (PAL). This is often used in security cameras. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 192 Signaling Signaling, also known as call control, sets up, manages and ends a connection or call. These messages include the authorization to make the call, checking bandwidth, resolving endpoint addresses, and routing the call through different servers. Signaling is transmitted via the H.225.0/Q.931 and H.225.0/RAS protocols in H.323 calls, or by the SIP headers in SIP calls. Signaling occurs before the control aspect of call setup. SIP Session Initiation Protocol (SIP) is a signaling protocol for starting, managing and ending voice and video sessions over TCP, TLS or UDP. Videoconferencing endpoints typically are compatible with SIP or H.323, and in some cases (like Avaya Scopia® XT Series), an endpoint can be compatible with both protocols. As a protocol, it uses fewer resources than H.323. SIP Server A SIP server is a network device communicating via the SIP protocol. SIP URI See URI on page 196. SIP Registrar See Registrar on page 191. Single Sign On Single Sign On (SSO) automatically uses your network login and password to access different enterprise systems. Using SSO, you do not need to separately login to each system or service in your organization. Slider See Content Slider on page 180. SNMP Simple Network Management Protocol (SNMP) is a protocol used to monitor network devices by sending messages and alerts to their registered SNMP server. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 193 Software endpoint A software endpoint turns a computer or portable device into a videoconferencing endpoint via a software application only. It uses the system's camera and microphone to send image and sound to the other participants, and displays their images on the screen. For example, Scopia® Desktop Client or Scopia® Mobile. SRTP Secure Real-time Transport Protocol (SRTP) adds security to the standard RTP protocol, which is used to send media (video and audio) between devices in SIP calls. It offers security with encryption, authentication and message integrity. The encryption uses a symmetric key generated at the start of the call, and being symmetric, the same key locks and unlocks the data. So to secure transmission of the symmetric key, it is sent safely during call setup using TLS. SSO See Single Sign On on page 193. Standard Definition See SD on page 192. Streaming Streaming is a method to send live or recorded videoconferences in one direction to viewers. Recipients can only view the content; they cannot participate with a microphone or camera to communicate back to the meeting. There are two types of streaming supported in Scopia® Solution: unicast which sends a separate stream to each viewer, and multicast which sends one stream to a range of viewers. STUN A STUN server enables you to directly dial an endpoint behind a NAT or firewall by giving that computer’s public internet address. SVC SVC extends the H.264 codec standard to dramatically increase error resiliency and video quality without the need for higher bandwidth. It is especially effective over networks with high packet loss (like wireless networks) which deliver low quality video. It splits the video stream into layers, comprising a small base layer and then additional layers on top which enhance resolution, frame rate and quality. Each additional layer is only transmitted when bandwidth permits. This allows for a steady video transmission when available bandwidth varies, providing better quality when the bandwidth is high, and adequate quality when available bandwidth is poor. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 194 SVGA SVGA defines a video resolution of 800 x 600 pixels. SQCIF SQCIF defines a video resolution of 128 x 96 pixels. Switched video Switching is the process of redirecting video as-is without transcoding, so you see only one endpoint's image at a time, usually the active speaker, without any video layouts or continuous presence (CP). Using video switching increases the port capacity of the Scopia® Elite MCU only by four times. Important: Use switched video only when all endpoints participating in the videoconference support the same resolution. If a network experiences high packet loss, switched video might not be displayed properly for all endpoints in the videoconference. SXGA SXGA defines a video resolution of 1280 x 1024 pixels. Telepresence A telepresence system combines two or more endpoints together to create a wider image, simulating the experience of participants being present in the same room. Telepresence systems always designate one of the endpoints as the primary monitor/camera/codec unit, while the remainder are defined as auxiliary or secondary endpoints. This ensures that you can issue commands via a remote control to a single codec base which leads and controls the others to work together as a single telepresence endpoint. Telepresence - Dual row telepresence room Dual row telepresence rooms are large telepresence rooms with two rows of tables that can host up to 18 participants. TLS TLS enables network devices to communicate securely using certificates, to provide authentication of the devices and encryption of the communication between them. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 195 Transcoding Transcoding is the process of converting video into different sizes, resolutions or formats. This enables multiple video streams to be combined into one view, enabling continuous presence, as in a typical videoconferencing window. UC (Unified Communications) UC, or unified communications deployments offer solutions covering a wide range of communication channels. These include audio (voice), video, text (IM or chat), data sharing (presentations), whiteboard sharing (interactive annotations on shared data). Unbalanced Microphone An unbalanced microphone uses a cable that is not especially built to reduce interference when the cable is long. As a result, these unbalanced line devices must have shorter cables to avoid audio disruptions. Unicast Streaming Unicast streaming sends a separate stream of a videoconference to each viewer. This is the default method of streaming in Scopia® Desktop server. To save bandwidth, consider multicast streaming. URI URI is an address format used to locate a device on a network, where the address consists of the endpoint's name or number, followed by the domain name of the server to which the endpoint is registered. For example, @. When dialing URI between organizations, the server might often be the Avaya Scopia® PathFinder server of the organization. URI Dialing Accessing a device via its URI on page 196. User profile A user profile is a set of capabilities or parameter values which can be assigned to a user. This includes available meeting types (services), access to Scopia® Desktop and Scopia® Mobile functionality, and allowed bandwidth for calls. VFU See Video Fast Update (VFU) on page 197. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 196 VGA VGA defines a video resolution of 640 x 480 pixels. Videoconference A videoconference is a meeting of more than two participants with audio and video using endpoints. Professional videoconferencing systems can handle many participants in single meetings, and multiple simultaneous meetings, with a wide interoperability score to enable a wide variety of endpoints to join the same videoconference. Typically you can also share PC content, like presentations, to other participants. Video Fast Update (VFU) Video Fast Update (VFU) is a request for a refreshed video frame, sent when the received video is corrupted by packet loss. In response to a VFU request, the broadcasting endpoint sends a new intraframe to serve as the baseline for the ongoing video stream. Video Layout A video layout is the arrangement of participant images as they appear on the monitor in a videoconference. If the meeting includes a presentation, a layout can also refer to the arrangement of the presentation image together with the meeting participants. Video Resolution See Resolution on page 191. Video Switching See Switched video on page 195. Virtual Room A virtual room in Scopia® Desktop and Scopia® Mobile offers a virtual meeting place for instant or scheduled videoconferences. An administrator can assign a virtual room to each member of the organization. Users can send invitations to each other via a web link which brings you directly into their virtual room. Virtual meeting rooms are also dialed like phone extension numbers, where a user’s virtual room number is often based on that person’s phone extension number. You can personalize your virtual room with PIN numbers, custom welcome slides and so on. External participants can download Scopia® Desktop or Scopia® Mobile free to access a registered user's virtual room and participate in a videoconference. Deployment Guide for Avaya Scopia® XT Series Version 8.3 Glossary of Terms for Scopia® Solution | 197 VISCA Cable A crossed VISCA cable connects two PTZ cameras to enable you to use the same remote control on both. Waiting Room A waiting room is a holding place for participants waiting for the host or moderator to join the meeting. While waiting, participants see a static image with the name of the owner's virtual room, with an optional audio message periodically saying the meeting will start when the host arrives. Webcast A webcast is a streamed live broadcast of a videoconference over the internet. Enable Scopia® Desktop webcasts by enabling the streaming feature. To invite users to the webcast, send an email or instant message containing the webcast link or a link to the Scopia® Desktop portal and the meeting ID. WUXGA WUXGA defines a video resolution of 1920 x 1200 pixels. XGA XGA defines a Video resolution of 1024 x 768 pixels. Zone Gatekeepers like Avaya Scopia® ECS Gatekeeper split endpoints into zones, where a group of endpoints in a zone are registered to a gatekeeper. Often a zone is assigned a dial prefix, and usually corresponds to a physical location like an organization's department or branch.
