BCM-DTM
The BCM-DTM is a trunk module that connects a T-1 or PRI trunk to the BCM system adding up to 24 digital telephone lines. On international BCM systems, the BCM-DTM connects to an E1 or PRI digital line. With an E1 or PRI line, up to 30 digital telephone lines can be added. A maximum of three BCM-DTM modules can be installed on the BCM system. The Digital Trunk Module is supported in the BCM main cabinet only (the DTM is not supported in the expansion chassis). (R2 MFC E-1 is not supported at this time, but is planned for release in 2005 (CALA).)
The front faceplate of the BCM-DTM has a number of LEDs that indicate power status and any ongoing tests and alarms that the module is undergoing. The faceplate also has an RJ-48C connector that connects the BCM-DTM to the service provider’s connection point and a set of loopback connectors used to run loopback tests.
