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.

The DTM module supports the following protocols:

 PRI

 DASS2

 DPNSS
