Selecting MBMs for your BCM system

MBMs are plug-in devices that connect your extensions and the public switched telephone

There are three types of MBMs:
• Trunk media bay module (see
• Station media bay module (see
• Specialized media bay module (see
For further information on the role and function of each type of MBM, refer to
