1.3 TECHNOLOGY
SWITCHING
System switching is accomplished by means of a custom IC “engine” \
that provides 256 
switchable digital channels. When expanded to a two cabinet system the m\
atrix is ex-
panded to 512 digital channels.  The engine is controlled by its own 16 \
bit Motorola MC
68302 microprocessor and switching control program. The 68302 microproce\
ssor is spe-
cifically designed for communication systems. Each of the 512 digital ch\
annels is auto-
matically assigned to carry...

processor (ECP) is coupled with the primary processor expanding the system to 512 PCM
channels. Secondary processors are located on station and trunk cards. The tertiary level
of processing is done in the keysets. The digital keysets use a Hitachi H8 processor for
data communication within the DCS 400si.
1.4 PROGRAMMING
The DCS 400si is a self-configuring system. This means that immediately after applying
power, the DCS 400si reads the types and locations of all installed cards and...
