Power supply mounting bracket
The BCM50 single power supply mounting bracket enables you to install one power supply unit
on the wall next to your BCM50 system. The power supply mounting bracket helps you keep the
power cables neatly organized.
Wiring field card
The wiring field card (WFC) simplifies the connections of lines and extensions to the main unit.
The WFC installs into the cable-management tray of the wall-mount bracket and connects to the
RJ-21 telephony connector through a 50-pin header.
The WFC contains 12 eight-pin modular jacks for digital stations, 4 eight-pin modular jacks for
analog trunks, and 4 eight-pin modular jacks for analog stations. The eight-pin modular jacks
accept RJ-45 or RJ-11 modular plugs.
A terminal block is available to connect auxiliary equipment. A 50-pin header connects to the
BCM50. See the figure
Wiring field card on page 50.
