PART 2. HARDWARE DESCRIPTIONS
2.1 MAIN CABINET
The main cabinet functions in-
dependently as a stand alone
192 port system or it may be
combined with the expansion
cabinet to make 384 ports.
The cabinet is comprised of a
card cage and a passive back
plane enclosed in a sturdy
metal cabinet that can be wall
mounted or set on casters.
Top, front and side panels can
be easily removed for instal-
lation and servicing. The main cabinet comes with a power distribution board and AC
power card mounted in the left side.
The main cabinet provides ten (10) universal card slots. A variety of interface cards for
stations, trunks and miscellaneous functions are installed in these 10 slots. Dedicated
slots are provided for the Common Control Processor (DCCP) and two (2) power con-
verter units (see Figure 2–1).
An optional single line ring generator with message waiting lamp supply can be installed in
the left side of the cabinet. The right side of the cabinet provides space for an optional 16
circuit power failure transfer card and functions as a cable channel for 25 pair amphenol
cables to the MDF.
2.2 EXPANSION CABINET
The expansion cabinet
mounts directly on top of the
main cabinet and locks in
place to provide a fully ex-
panded 384 port system. The
expansion cabinet is virtually
identical to the main cabinet.
It also has 10 universal slots
and 3 dedicated slots for 2
power supplies and an Expan-
sion Control Processor
(DECP). An optional ring gen-
erator with message waiting lamp supply and 16 circuit power failure transfer board can
also be mounted in the expansion cabinet.
