RAD FCD-2 E1 or
Fractional E1 Access Unit

FEATURES The FCD-2 is a Rate and Interface Converter for Fractional E1 services, accepting data at rates from 56 kbps to 1.984 Mbps. User data is placed into an E1 (CEPT) frame, using only the required number of timeslots. Synchronous data channel connection is provided over the public E1 (CEPT) network without the need for a multiplexer. Where a Fractional E1 service is available, the FCD-2 reduces payment to only the bandwidth used. The FCD-2 is compatible with virtually all carrier provided E1 services, meeting all requirements of CCITT recommendations for G.703, G.704 and G.732. It supports both 2 or 16 frames per multiframe, with or without CRC-4. Zero suppression over the line is HDB3. Selectable timesloting allows data to be placed into
timeslots, either consecutively or as defined by the user. The data rate can
be programmed for any multiple of The unit can be ordered with or without an LTU (Line Terminating Unit), allowing for operation either with the integral LTU or with an external unit. Three user interfaces are available: V.35, X.21 and V.36/RS-530, with selectable clock sourcing (see Ordering). The integral LTU ensures an operating range of up to one mile, allowing the FCD-2 to be used also as a short range modem. Multiple clock source selection ensures maximum flexibility on both the E1 and the user interfaces. The E1 line may be clocked from the recovered receive clock, or from an internal oscillator. The user interface may be set to DTE or DCE with external transmit clock, or DCE where both receive and transmit clocks are inputs. Setup, control and monitoring of status and diagnostic information can be activated via 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 BER test for rapid identification of faults.
