This chapter describes the system’s basic hardware. It includes descriptions of the control unit, MLX telephones, analog multiline telephones, single-line telephones, system operator consoles, adjuncts and adapters for the system and telephones, and power-related accessories.

Control Unit

3

The control unit connects the telephone company’s outside trunks to the system’s telephones and adjuncts. It is the heart of the system, managing the traffic within the system (inside calls) and making telephone company facilities and outside services available to your company. It includes the following components:

■Carriers (up to three)

■Processor module (one per system)

■Power supply module (one per carrier)

■Line/trunk and extension modules (up to 17 total in three carriers)

■Cover that protects the unit

Carriers

3

The carriers in the system are the containers that hold the modules on which the circuit boards and connections for lines/trunks and extensions (called jacks or ports) are located. There can be up to three carriers: one basic carrier and two expansion carriers.

The carriers hold the modules in slots. For the purposes of system programming and installation, 2-digit numbers indicate the slots, starting with 00 for the processor module.
