Connecting the lines and extensions
The telephone lines and extensions connect to the BCM50 system through an RJ-21 telephony
connector on the front of the main unit and to the connectors on the MBM installed in the
expansion units.
You can also use the optional wiring field card (WFC) to simplify the connection of the lines and
extensions to the RJ-21 telephony connector in a wall-mount or desktop-mount installation. For
rack-mount installations you can use the optional rack-mount patch panel.
