FCD-24 Integrating E1 Multiplexer

RAD FCD-24 Integrating E1 Multiplexer

FEATURES
  • The FCD-24 is an Integrating Multiplexer for E1 and Fractional E1 services. Two or four synchronous data channels and one E1 sub-link 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.
  • Four FCD-24 models are available:
    (see Ordering)
    FCD-24 with four synchronous data channels;
    FCD-24/E1 with four synchronous data channels and one E1 sub-link;
    FCD-24-2 with two synchronous data channels;
    FCD-24-2/E1 with two synchronous data channels and one E1 sub-link.
  • Data rates are selectable for any multiple of 64 kbps. Selectable timeslotting places data into timeslots (DSOs) either consecutively (bundled), or by user-definition (without restrictions). Selected timeslots on the E1 sub-link are bypassed to the same timeslots on the E1 main link.
  • Data channel interfaces available are V.35, X.21, RS-530 or V.36/RS-449. (V.36/RS-449 is converted from RS-530 via cables supplied with V.36 interface option - see Ordering.)
  • The FCD-24 is compatible with virtually all carrier-provided E1 services, meeting all requirements of ITU-T G.703, G.704 and G.732. It supports 2 or 16 frames per multiframe, with or without CRC-4. Zero suppression over the line is HDB3. An optional integral LTU (Line Termination Unit) supports ranges up to 1.6 km (1 mile), enabling the FCD-24 to be used as a multi-channel short range modem for private applications.
  • Multiple clock source selection allows the E1 main link to be clocked from the recovered clock (LBT), from the data channel source, from E1 sub-link, or from an internal oscillator.
  • Data channels may be set to DCE (FCD-24 provides RX and TX clocks to user equipment), DTE1 (FCD-24 provides RX clock to user, while TX clock is received from user) or DTE2 (both clocks received from user) clocking modes.
  • The E1 sub-link transmit clock is locked to the E1 main link clock. The receive clock can be used as an external clock source for the E1 main link transmit clock.
  • Setup, control and monitoring of status and diagnostic information can be activated from the front panel or via a terminal or PC connected to the supervisory port.
  • Remote line diagnostics, alarm information, unit configuration and other control/monitoring information can be accessed remotely via dial-up modems.
  • Maintenance capabilities include local and remote loopbacks at various points, as well as built-in BERT for rapid identification of faults.
  • For dial-out operation, the FCD-24 activates the modem to automatically dial a pre-programmed number whenever an alarm event occurs.
