Hardware architecture

CS 1000M and Meridian 1systems 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 35) on Figure 13 "Large System basic architecture" (page 35)):

•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 35), 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.
