Media Modules
MM720 BRI Media
Module
The MM720 BRI Media Module contains eight ports that can be administered
either as BRI trunk connections or BRI endpoint (telephone and data module)
connections. Information is communicated in two ways:
Over two 64 Kbps channels called B1 and B2 that can be circuit-switched
simultaneously
Over a 16 Kbps channel called the D channel that is used for signaling. The D
channel occupies one time slot for all eight D channels.
The circuit switched connections have a u-law or A-law option for voice
operation. The circuit switched connections operate as 64 Kbps clear channels
when in the data mode.
The MM720 BRI Media Module does not support combining both B channels
together to form a 128 Kbps channel.
Note:
Note:
For BRI trunking, the MM720 BRI Media Module supports up to eight BRI
interfaces, or up to 16 trunk ports, to the central office at the ISDN S/T
reference point.
For BRI endpoints, each of the 8 ports on the MM720 BRI Media Module can
support one integrated voice/data endpoint or up to 2 BRI stations and/or data
modules. Supported endpoints must conform to AT&T BRI, World Class BRI, or
National ISDN NI1/NI2 BRI standards. The MM720 BRI Media Module provides
-40 volt phantom power to the BRI endpoints.
MM722 2-port BRI Media
Module
The MM722 BRI Media Module supports two BRI ports.
