Wiring the MBMs

This section describes how to wire the cables that connect to the station and trunk MBMs.

•The station MBMs have one or two 50-pin amphenol connectors that require 25-pair cables to connect the MBMs to the equipment in the telephone room where your demarcation point is located. Use a qualified technical professional to ensure the cable wiring and your interior telephone wiring are correct.

•The trunk MBMs connect to central office trunks using RJ-type jacks. However, the GATM4 and GATM8 have a 50-pin amphenol connector that requires a 25-pair cable to connect to the Central Office (CO) trunk. These cables can be supplied by qualified technical personnel to ensure the correct pin-out.
