FCD-1L low-cost, single port CSU/DSU for T1 or Fractional T1 services

The FCD-1L is a low-cost, single port CSU / DSU for T1 or Fractional T1 services. The DTE port is selectable for any data rate multiple  of 56 or 64 kbps up to 1536 kbps. User data is placed into a T1 frame, using only the selected number of timeslots. Timeslot  assignment is according to the data port speed and is consecutive starting from any timeslot. 

RAD FCD-1L low-cost, single port CSU/DSU for T1 or Fractional T1 services

The FCD-1L T1 interface is compatible  with carrier provided T1 services, including ASDS from AT&T, meeting all requirements of TR-62421. It supports both D4 and ESF  framed formats. Zero suppression over the line is selectable for either Transparent, B7ZS or B8ZS. The integral CSU ensures a range  of up to 1 mile. The main T1 link may be clocked from the T1 network recovered clock, from the DTE or from an internal oscillator. The  DTE port interface is internally selectable for V.35, RS-530/422. The physical connector is 25 pin D-type female. Special adapter  cables can be ordered separately for X.21 and RS-449/422 (see Ordering section of the data sheet). Setup and control of the FCD-1L is by internal jumpers. Front panel switches control all diagnostics options. Maintenance capabilities  include user activated local loopbacks at the main T1 link and DTE port. The FCD-1L responds to network activated loops (RLB, LLB).  The DTE port can respond to an in-band ANSI FT1 loop code that can be generated from the remote FCD-1L DTE port. A pseudo  random data pattern (BERT) can be transmitted for diagnosing the T1 link. The FCD-1L displays two alarm types on front panel: major  alarm and minor alarm. The alarms are displayed by front panel LEDs which can be reset by front panel switch. The FCD-1L has a  Severely Errored Second indicator (SES). This indicator is ON when the Bit Error Rate (BER) on the T1 line is above 1 x 10-3. When  operating in the ESF format, T1 network statistics are stored in memory in compliance with the ANSI version. This information may be  retrieved by the service supplier. The FCD-1L is available as a stand-alone unit or as a card for the 19" rack that can accommodate up to 14 cards (ASM-MN-214). A rack mount adapter kit (RM-9) enables installation of one or two stand alone units in a 19" rack.
