Wiring MBMs to internal connections

After you wire the trunk MBMs, you can install the wiring to the station MBMs. These are the MBMs that connect to the internal telephone sets.

All station MBM wiring uses 25-pair cable with a female amphenol connector at the MBM end.

Note: DSM 32 MBMs require two 25-pair cables.
