2.06 The internal arrangement of the telephones

is based

on

the use of a molded plastic chassis to which the components of the set are attached and an electrical interconnect field into which the components are plugged (Fig.

5).

The

interconnect field also contains positions for plugging

in optional features and switches A through H for

adapting the set to options. Outside connections

the mounting cord plugs into a wiring harness which distributes leads to the line key

and the control logic board. In the other desk-type sets, the mounting cord plugs directly into the line key. The system connector cable is intended to

be

plugged directly into the wall sets without the use of mounting cords, which are not supplied with wall sets.

2.07 Mounted

on

the base of each primary set is

a logic board containing control and power

circuitry for two

lines and one intercom
