Field descriptions
XRATE
(cont’d.)
XRATE may be 64 when the endpoint dials in, or in the event
that problems occur. It implies that only one B channel is in use.
AUDIO
Conference and endpoint Audio rates (kbps bandwidth) must
be the same. Their modes are not necessarily the same. When
the audio rate of the conference and the endpoint differ, the
endpoint’s audio interworks, but the endpoint’s video is invalid.
MCU may or may not send video to such an endpoint.
Table 8-13 on page 8-348 summarizes expected endpoint
audio modes with different transfer rate configurations, facility
bandwidths, and conference modes. It includes endpoints that
support the highest common audio mode (HC audio) when the
administered mode is
auto. The highest common conference
mode depends on the administered bandwidth. A ‘-’ in the table
indicates ‘does not apply.’
