System Control Interface Hardware & Syscon Software

The System Control Interface (SCI) operates in conjunction with the TSC Channel cards to form a complete trunking site, but remember it is not essential.

The primary function of the SCI is to connect the channel cards to other parts of the network. This could be a system terminal PC for a single-site system, or the Regional Control Processor if a multi-sited wide area network. The SCI additionally provides billing, control, status reports, customer validation and local phone interconnects.

Part of the SCI is a SIMM module. The SIMM module is available in options ranging from a standard 2M SRAM to a 16M SRAM capable of storing up to 100,000 billing records and 100,000 subscriber records. The module is situated on the rear panel and is easily removed by undoing 4 captive screws. The System Control terminal, SYSCON, operates in conjunction with the infrastructure to provide user management and system control functions from one software package. Syscon is designed to run 24 hours a day, using Windows NT as a platform.
The database is stored in Microsoft Access format so data is readily available for external processing and the generation of statistics.

Syscon offers a full set of diagnostic tools, covering every aspect of network operation. In the unlikely event that any errors occur within the network they will be reported back to the terminal - from where the operator can investigate further and take the appropriate action. SYSCON supports a dial-up Modem connection as well as a direct connection to remote infrastructure locations.


Fylde PCM Switch

The PCM switch is built using a modular system, based on slot in cards and a 19" rack mount chassis. A maximum of 48 switch cards, mounted in three 6U card frames, may be connected together to provide 192 non-blocking ports. Now available: Connection to E1 / T1 digital lines. Analogue and digital cards utilise the same form factor and maybe installed in the same switch frame. Each analogue card offers 4 private circuit connections or 2 PABX / PSTN and 2 private circuit connections. Each port is presented on a standard RJ45 socket.

Each digital card offers upto 30 ports, connected directly to an E1 line. Connections to a T1 circuits provide the standard 24 ports. Fractional 64kbps circuits and telephone signalling are not supported.
