Architecture
The Base Cabinet and optional Expansion Cabinets are the building blocks of the system. Each
system has a Base Cabinet, and can have from one to four Expansion Cabinets. All lines, stations,
and options are tied together through the cabinets.
Processor PCBs
The system operates with one of four processors (B1CU, B2CAU/B2CBU, B3CAU/B3CBU, or
B5CAU/B5CBU). These processors can only be installed in dedicated slots in the Base Cabinet
(slots B101 and B102).
♦
B1CU – a single processor PCB that supports only the DK424i Base Cabinet with up to eight
universal slots.
♦
B2CAU/B2CBU – two PCBs that support up to two cabinets, with up to 14 universal slots.
Expansion Cabinet slots S207~S210 are
not
available with the B2CAU/B2CBU processors.
♦
B3CAU/B3CBU – two PCBs that support up to three cabinets, with up to 28 universal slots.
♦
B5CAU/B5CBU – two PCBs that supports up to five cabinets, with up to 48 universal slots.
Each processor provides a MOH/BGM source interface, and connectors to mount optional DTMF
receiver PCBs required for some CO line types and peripherals, as described below. Each
processor provides an interface for connecting an optional feature key (RKYS) as described below.
B3CAU/B3CBU and B5CAU/B5CBU require a remote maintenance PCB, usually installed in slot
S101; the remote maintenance PCB is optional for the B1CU and B2CAU/B2CBU.
