Control Unit

DESCRIPTION

Modules

The basic carrier contains slots for up to seven modules, which supply power,

direct system operation, and provide jack connections for telephone lines,

voice terminals, and other equipment, such as a tape player for the Music-

on-Hold feature. See Figure 2-19. You can also add to your system one

expansion carrier which provides more power and additional connections for

lines and equipment.

Your MERLIN II system may include up to 56 outside

lines and as many as 88 connections for voice terminals or other equipment,

depending on the combination of modules installed. However, you can have

only 82 responding stations.

The following modules are used in the MERLIN II system:

● Power Supply Module.

A Power Supply Module, which supplies power

to the other modules in the unit, always occupies the leftmost slot on the

basic carrier and the expansion carrier.

There is an Off/On switch at the

bottom of the module. When the power is on, a green light is on next to

the switch.
