Hardware architecture
CS 1000M and Meridian 1 systems are circuit-switched digital systems
that provide voice and data transmission. The internal hardware is divided
into the following functional areas (see
on
Figure 13 "Large System basic architecture"
•
Common Control Complex (Common Equipment) circuit cards provide
the processor control, software execution, and memory functions of
the system.
•
Network Interface (Common Equipment) circuit cards perform switching
functions between the processor and Intelligent Peripheral Equipment
(IPE) cards.
Note: As shown in
Figure 13 "Large System basic architecture" (page
, the network interface function is generally considered a subset of
the Common Equipment functions.
•
IPE circuit cards provide the interface between the network and
connected devices, including Terminal Equipment and trunks.
•
Terminal Equipment includes telephones and attendant consoles (and
may include equipment such as data terminals, printers, and modems).
•
Power Equipment provides the electrical voltages required for system
operation and cooling, and sensor equipment for system protection.
