System architecture

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

Figure 13 "Large System basic

architecture" (page 37)

on

Figure 13 "Large System basic architecture"

(page 37)

):

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

37)

, 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.
