The BCM50 interfaces are designed so that you do not need additional hardware. See Figure 1 for a graphical representation of the BCM50 interfaces.

Your BCM50 comes with these interfaces:

•Twelve digital station ports that support the complete line of Business Series Telephones. These ports are accessible through the front pane RJ-21 connector and are enabled through keycodes.

•Four Analog Loop Supervised Trunks. These ports are accessible through the front panel RJ-21 connector and are enabled through keycodes.

•Four Analog Station interfaces with message waiting and CLID support. These ports are accessible through the front panel RJ-21 connector are enabled through keycodes.

•Page and auxiliary relay output on the front panel RJ-21 connector.

•Three-port 10/100 Ethernet switch with auto sensing and auto polarity. Two of these ports also support connecting optional expansion units.

•One 10/100 Ethernet port reserved for direct access management of the system.

•Music on hold input supported either through front panel jack or RJ-21 connector.

•USB port to enhance BCM50 management.

You can extend the capacity of your system by using the optional “BCM50 expansion unit and media bay modules” on page 18.
