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.


MB 990: Mother board. This card is the motherboard in a

euro-rack. The power supply (or

supplies), the system and the interface cards are inserted into

the rack. The mother board can accommodate two power supplies

and 16 system and interface cards. Several racks can be linked to each other using a simple single flat cable. A power

line sensor module monitors both power supplies and measures the ambient temperature

CDM 990: Co-directional Digital Module. This card supports digital co-directional G.703 64Kbit (leased)

lines. Its main application is to connect to the compact voice switch, although any G.703 protocol could be implemented.

Three transceiver connections with E&M signalling are available. The card can be provided with an optional ATS-QSIG protocol that

enables three voice channels and a digital connection to be included over a 64Kbit connection (note that G.728 voice compression is not suitable for line modems).

CVS 990: Compact Voice Switch 990

The CVS990 switch is a compact version of the TCS990. The CVS990 is composed of one up to four DMI990 and corresponding interface cards. The cards are

mounted in a 1HE high casing. The casing includes a 230VAC/100W power supply and a power supply connection for local transceivers.

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.
