Aud
“y” = the endpoint has the required audio capability. Audio
add-on endpoints always set the Aud field to y when the
endpoint joins the conference.
“c” = the endpoint is PCM only and it changes the conference
video quality by changing the operating audio from G.728 to
G.711. If administered audio modes are auto and the
administered bandwidth is 112 kbps (56 k/channel) or 128 kbps
(64 k/channel), the system initiates with the highest common
audio, G.728. When the administered bandwidth is greater than
128 kbps, the system initiates with the highest common
bandwidth, 7 kHz.
“e”= A PCM-only endpoint that could not support the
administered audio mode, G.728 (such as a data conference),
or G. 278/G.711 endpoint that could not support the
administered audio mode, 7 kHz. Such endpoints operate with
PCM audio and interwork with current operating audio modes.
blank = blank until the first call from or to the endpoint.
Vid
“y” = the endpoint has the required video capability and should
be receiving video if the Chl, Aud, and Dat fields are
y
.
“c” = downgraded conference video quality from changing CIF to
ACIF or by decreasing the frame rate. The conference video
mode defaults to CIF If QCIF-only endpoints join the
conference, the entire conference operates in QCIF, with
downgraded video clarity. The conference frame rate is initially
set to the highest frame rate that can be reduced by any
endpoint. If the conference video mode is not administered with
upgrade capability, the video parameters for a conference are
“downgraded.” They are not “upgraded” until all endpoints
disconnect from the conference.
“e” = the endpoint doe not declare video capability in its cap-set.
“n” = audio only, not receiving video, due to audio or data
problems.
“blank” = Audio add-on endpoint defaults the Vid field to
blank
.
Mlp
Control Link to the ESM (T.120 stack terminator) status, the
endpoint MLP data capability, and the state of the data
connection in the T.120 stack. This field defaults to
blank
,
indicating that the Data Mode for the conference is
none
.
Gx
“y” = This endpoint has Still Frame Graphics capability.
e = This endpoint does not have Still Frame Graphics capability.
The conference retains still frame graphics capability when
non-compliant endpoints join the conference.
blank = This endpoint never joined the conference.
