Media Modules
The MM720 BRI Media Module contains eight ports that interface to the central
office at the ISDN T reference point. 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 BRI stations, or combining both
B channels together to form a 128 Kbps channel.

The MM760 VoIP Media Module is a clone of the motherboard VoIP engine. It
provides an additional 64 VoIP channels with G.711 compression. Each chassis
base system can support up to 64 G.711 single channel calls. If the desire is to
have an essentially non-blocking system, an additional MM760 VoIP Media
Module needs to be added if more than two MM710 T1/E1 Media Modules are
used in a single chassis. This will provide for an additional 64 channels.
This VoIP conversion resource in the G700 Media Gateway is an improved
version of the Prowler board resource and from a configuration perspective, the
two are the same. The capacity is 64 G.711 TDM/IP simultaneous calls, or 32
compression codec (G.729 or G.723) TDM/IP simultaneous calls. These call
types can be mixed on the same resource, so we say that the simultaneous call
capacity of the resource is 64 "G.711 Equivalent Calls".
