752 Installing and Upgrading the Avaya G700 Media Gateway and Avaya S8300 Media Server
MM717 24 port DCP
Media Module
Comcode (for Services Ordering Only): 700302433
The MM717 DCP Medial Module supports 24 DCP stations. The MM717 uses a
25-pair amphenol connector on the media module’s faceplate. The 24 DCP ports
are intended for in-building use only. Phone lines connected to those ports are
not to be routed out-of-building. Failure to comply with this restriction could
cause harm to personnel or equipment.
NOTE: No more than 3 MM717 Media Modules can be installed in a single
G700.
MM720 BRI Media
Module
Comcode (for Services Ordering Only): 700315591
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: The MM720 BRI Media Module cannot be administered to
support both BRI trunks and BRI endpoints at the same time.
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.
