Power pairs are polarity sensitive; pins 7,4, and 6 must be the same polarity.
3.6. 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.
Multiple Power Pairs
Some sites may prefer to wire Base Stations to a separate demarc block in order to split
out power pairs.
