BCM200/BCM400 base units
In conjunction with the BCM version 3.0 system release, Nortel released two new base unit
models to provide added flexibility for system planning. These systems come preloaded with the
latest version of software. You cannot run versions previous to BCM 3.0 software on these units.
However, you can reuse modules from previous versions of the system, if you are replacing old
system hardware with the new BCM200 or BCM400 hardware (shown below). For a detailed
description of this hardware, and how it is installed and maintained, refer to the Business
Communications Manager BCM200/BCM400 Installation and Maintenance Guide.
