Media Bay Modules

Media Bay Modules are installed in the BCM450's main unit to provide trunk
and extension capability. They can also be installed in the BCM450's
expansion unit to increase the Trunk and Extension capacities of the BCM.
Each Media Bay Module has a series of dipswitches located on the rear of the
unit. The dipswitches should be set as detailed in the BCM450 Media Bay
Modules Guide.
Note: For full details of Media Bay Module assignment, installation, and
configuration, please refer to the BCM450 Media Bay Modules Guide.

Supported Media Bay Modules

The following Media Bay Modules are supported on the BCM450:

expansion modules to the BCM)
o R2MFC

Media Bay Module Descriptions

The following sections describe the hardware attributes and functionality of
the Media Bay Modules.
Digital Trunk Modules
When configured on a North American BCM system, the DTM connects a T1
or PRI circuit to the BCM system; T1 circuits provide 24 digital channels to the
PSTN, while PRI circuits provide 23 digital channels to the PSTN.
When configured on an International BCM system, the DTM connects an ETSI
ISDN (E1) or PRI (E1) circuit to the BCM system, providing a maximum of 30
digital channels to the PSTN
