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.
