Polycom 1725-36122-001, MCS300, JPI300 manual Prepare Demarc Blocks, Interface Type

Site Preparation

When wiring multiple power pairs, use the following table as a guide.

Pair	Function	Pin #s
1	Data	1,2
2	PWR 1	7,8
3	PWR 2	4,5
4	PWR 3	6,3

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.

Analog POTS

Universal (Comdial, DEFINITY, Meridian 1, Norstar, Rolm)

Four-wire digital

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.
