TeleCommunication Switch 990 The TCS990 is a digital switch, specially developed to meet the specific needs defined for traffic operators working at control centres. The switch is used in the following application areas: public safety, ATC (Air Traffic Control), the maritime sector, ARBI, PBX and Public Addressing systems. The switch is a flexible and extremely scalable system. The smallest switch comprises of just one system card and one interface card. This configuration has a capacity of 8 voice channels. The maximum capacity is achieved using four 3HE euro-racks, each holding 16 system cards totalling the system capacity to 512 voice channels. Using configurable multi-slots, broadband audio for high-quality voice and PA systems can easily be assembled. The system is implemented using as little jumpers as possible and is configured and managed using a software control & monitor program. The system can be remotely maintained and updated with new firmware. In addition, built-in loop-back modes allow for good diagnostics. Due to the redundant system bus design and a multi-server structure, an extremely reliable telecommunication switch is guaranteed. The operator control panels are connected in a star instead of a ring configuration to ensure the maximum possible availability.
System cards The TCS990 is build with the following system parts.
DMI 990: Digital Matrix Interface. This is the general system card. All interface cards are linked to this card type. The system card has the following specifications: 300Mhz Digital Signal processor with 8 Mbyte SDRAM and 8 Mbyte Flash ROM. 300Kgate Field Programmable Gate Array and a redundant Low Voltage Differential Signalling system bus. Two serial telecom busses, four uarts/sdlc controllers, 16 system and 16 user I/O’s a 16 bits expansion bus and 10 LED signals.

LLI 990: Local Line Interface. The card can be used to create analogue and digital connections in the voice switch. This card supports four 2/4 wire analogue (M1030/1040) lines. The card can also hold four expansion modules. These expansion modules can be used to support a wide variety of (digital) line types. Together with the DMI990 the card supports an automatic analogue line system to the CLI990 or CVS990 with the following properties: adaptive echo cancelling, automatic line attenuation correction, automatic line equalization, remote signalling, automatic line monitoring, best signal selection and remote serial communication. It is also possible to connect transmitters/receivers locally. In this case the digital signals (PTT, SQL) are used and optionally other signalling functions like transceiver malfunction and retransmission can be connected.
LBI 990: Local Battery Interface The local battery interface is used for direct connection to a subscriber on a non amplified direct line. The card supports up to four lines and can work with ring in ring out or with Q8 signalling. The card has multiple ring generators to avoid a single point of failure.
CLI 990: Compact Line Interface The CLI990 is an euro card sized module. The CLI990 can accommodate one digital extension module. Together with the LLI990, the connection forms an automatic analogue line system. The CLI990 is positioned on the remote side of the line alongside the transmitter/receivers. The CLI990 has a connection for one transceiver. The transceiver connection has four photo-coupler input and output ports. These are used for squelch, transmitter malfunctions, emergency power, PTT, relays, channel selection and line malfunction. The digital line connection can consist of a BRM, PRM, ETM, SDM or a CDM990 expansion module. A RS422 asynchronous serial port is available for digital signalling. For best signal selection applications an analogue input port with programmable gain is available to measure the RSSI signals. The module can be mounted in a 19” rack. All external wiring is connected through RJ45 plugs which are located at the rear.

Software updates and reconfiguration The system is supplied with an automatic software distribution mechanism. If the server card is equipped with another software version as the client cards, the software of the server card will automatically be distributed. This update process will be continued until all components are updated. The update process will take 30 seconds to several minutes depending of the amount of system cards. The software updates over digital lines will take from 3 seconds to 6 minutes depending on the line type. The automatic distribution of software is only supported on digital lines. The system update process can be initiated in two ways. Firstly by placing a server card with the new software, or by uploading the new software from the CMSpro system.
