The FCD-1L is a
single port access unit for full or fractional T1 services. Data port rates are
selectable for any multiple of 56 kbps or 64 kbps up to 1,536 kbps. User data is
placed into a T1 frame, using only the required number of timeslots. Timeslot
assignment is performed according to the data port speed and is consecutive,
starting from any timeslot.
The RAD DSU meets all the requirements of TR-62411 and TR-62421. It supports
both D4 and ESF framing formats. Zero suppression over the line is selectable
for B7ZS or B8ZS.
The main RAD FCD-1L T1 link may be clocked from the recovered receive clock (LBT)
or from an internal oscillator.
The FCD-1L can have RS-530 data channel interface. Adapter cables are available
for V.35, V.36/RS-422 or X.21.
RAD FCD-1L setup and control is by internal jumpers. Front panel switches
control all diagnostic options.
The RAD FCD-1L Diagnostics include user-activated local loop-backs on the main
T1 link and DCE data port. A pseudo-random data pattern (BERT) can be used to
check the transmission path and the local and remote units. The FCD-1L can
display major and minor alarms, and indicate bit error rate on the T1 line in
excess of 1 x 10-3.
The RAD FCD-1L is available as a standalone unit or as a card in a 19" rack. An
adapter kit enables installation of one or two standalone units in a 19" rack.
