BCM Expansion Unit

The Business Communications Manager expansion unit contains six additional bays for media bay modules. The Business Communications Manager expansion unit is available for use only with the BCM400.

The supplied DS256 cable is 5 m (16 ft.) long. Use of any other cable is not supported. The cable connects into a DS256 port on the MSC of the base function tray, and into a DS256 port on the center panel of the expansion unit.

Note: The number of modules that actually can be installed is determined by the number of DS30 channels required by the modules and the number of channels available.
