UNIT MODULE
The Central Processing Module includes the following
components:
The Central Processing Unit Module (CPM) performs
all switching control functions for single and dual bay
configurations, provides on-screen setup programming
menus (refer to the
System Administrator Manual ), and
dictates the functions of other modules in the MP168
system.
The Central Processing Unit module supports standard
switching system input devices including keyboards,
printers, external computers, alarms, and auxiliaries.
The CPM module is always installed next to the Power
Supply Module (see Figure 1-5A).
NOTE: Only one Central Processing Unit Module
is required for dual bay configurations.
An ARCNET repeater resident in the
Power Supply Module provides direct
control functions to the second bay.
