Power pairs are polarity sensitive; pins 7, 4, and 6 must be the same

polarity.

Prepare Demarc Blocks

Interface Modules are designed to operate with a specific interface to

the telephone system: two-wire digital or analog, or four-wire digital

(future release). The number of demarcation blocks required for the

system depends on the number and type of Interface Modules to be

installed.

The CPU316 and CPM316 Interface Modules are intended only for
connection to the isolated-side of an on-premise PBX. These
interfaces are intended to connect to digital PBX ports that provide
signals of 5Vp-p (max) AC component and some PBXs providing a
48Vdc offset.

Base Station wiring is the same for all Interface Modules.
Based on the number and type of interfaces in the system, determine

the number of 25-pair cables required to connect line ports and Base

Stations to the demarcation blocks. The diagrams which follow

provide an overview of the connections.
