30 Overview for the Avaya G250 and Avaya G350 Media Gateways
The circuit-switched connections have an A- or Mu-law option for voice operation. The
circuit-switched connections operate as 64-kbps clear channels when in the data mode.
For BRI endpoints, the MM720 BRI media module supports up to 16 BRI stations and data
modules that conform to AT&T BRI, World Class BRI, and National ISDN NI1/NI2 BRI standards.
The MM720 BRI media module provides -40 volt phantom power to the BRI endpoints.

MM722 BRI media module
The MM722 BRI media module provides two 4 wire S/T ISDN BRI 2B+D access ports with
RJ-45 jacks. Each port interfaces to the central office at the ISDN T reference point. Information
is communicated in the same manner as for the MM720. See MM720 BRI media module
on
page 29.
