AUDIO Audio rate (kbps bandwidth) of the conference and the endpoint
must be the same but not nec essarily their mode. When the audio
rate of the conference and th e endpoint are different the en dpoint’s
audio will interwork but the endpoint’s video will be invalid. MCU may
or may not send video to suc h an endpoint.
Table 8-12 summarizes expected end point audio mod e with different
configurations of transfer rate, fac ility bandwidth, c onference mode,
and whether or not all endp oints support the highest c ommon audio
mode (HC audio) when the adminis tered mode is auto. The highest
common conference mod e is dependent o n the administered
bandwidth. A ‘-’ in the tab le indicates ‘d oes not apply.’

AUDIO
(cont’d.)
Other possible AUDIO mode v alues include neutral (neutralized
I-channel) and Au-off, Frm (no audio s ignal) which never matc h
conference mode and are not supported b y MCU.
