• Integrates high speed data and an E1 link into E1 or fractional E1 services
• Two or four data channels
• Data interfaces: V.35, RS-530/V.36 or X.21
• Selectable data rates: n x 64 kbps
• Setup and control via front panel or supervisory port
• Complies with ITU G.703, G.704 and G.732
• Dial-out on alarm events
• Diagnostic capabilities include local loopback, data port and BER test
• Setup and control is via the front panel or supervisory port

Product Summary

The FCD-24 integrating multiplexer supports E1 and Fractional E1 services. The FCD-24 integrating E1 multiplexer has two or four synchronous data channels and one E1 sub-link which can be connected over the public E1 network, while paying only for the bandwidth required. The E1 sub-link enables PABX connection to the E1 interface. Alternatively the unit can be used as a multi-channel short range modem.

Benefits

• Offers converged data and voice services over a single E1 or Fractional E1 circuit • Can serve as a rate or interface converter

Further Product Information

The FCD-24 is an integrating multiplexer for full and fractional E1 services. Two or four synchronous data channels and one E1 sub-link can be connected over the public E1 network. The E1 sub-link enables connection of user-defined timeslots from a PBX link to the main E1 interface. The FCD-24 interface connections are modular, supporting two or four channels with or without an E1 sublink. Data rates are selectable for any multiple of 64 kbps. Selectable timeslot allocation places data into timeslots either consecutively or user-defined, without restriction. Channel interface is V.35, RS-530 or X.21. An interface for V.36/RS-422 is also available using an adapter cable.

Integrating multiplexer for full and fractional E1 services

The FCD-24 is compatible with virtually all carrier-provided E1 services, meeting all requirements of ITU recommendations G.703, G.704 and G.732. It supports both two and 16 frames per multiframe. Zero suppression over the line is HDB3. An optional integral LTU (line termination unit) supports a range of up to 2 km (1.2 miles). Flexible clock source selection on the main link and data channels allows support for most applications. Setup, control and monitoring of status and diagnostic information can be activated via the front panel or via a terminal or PC, or remotely via dial-up modems. Maintenance capabilities include local and remote loopbacks, as well as a built-in BER tester. For dial-out operation, the FCD-24 automatically dials a pre-programmed number whenever an alarm event occurs.
