Media Bay Modules (Mbms) - Nortel BCM200 Installation And Maintenance Manual

The MBM backplane provides the MBM component interface to the power supply and main card.
The MBM backplane mounts at the rear of the MBM bays and is a non-replaceable component.

Media bay modules (MBMs)

The BCM system is modular. You can increase the capacity of the system by adding more media
bay modules (MBMs). Each BCM allocates a maximum of six DS30 buses to the MBMs. The
number of MBMs that can be added to your system is determined by the number of media bays
that are open, combined with the number of DS30 buses each component uses.
