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 Strata CT Base Cabinet with up
to eight universal slots.
◆
B2CAU/B2CBU – two PCBs that support up to two cabinets, with up to 18 universal
slots.
◆
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 Exchange 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.
lists the clock speed and available chips and memory for each processor.
