Caller ID Trunk Media Bay Module 4 (BCM-CTM 4)
The BCM-CTM 4 port connects up to four analog CLID PSTN lines to the BCM system. The
auxiliary port permits the connection of a 33.6+ Kbps modem, fax machine or single line analog
telephone to line 1. When the auxiliary device is using line 1, the BCM system does not allow
other telephones to use line 1. When a single line analog telephone is connected to the auxiliary
port, it can be used as an emergency telephone. The front faceplate of the BCM-CTM has four
RJ-11 connectors that connect the CTM to the service provider’s connection point.
The BCM-CTM faceplate also has two LEDs:
• Power (indicates operating status)
• Status (indicates hardware status).
