Aud
Does it have the required audio capability? -
y
,
c
,
e
,
blank
“y” = The endpoint has the required audio capability. Audio add-on
endpoints set the Aud field y when the endpoint joins the
conference.
“c” = This PCM-only endpoint changes conference video quality by
changing the operating audio from G.728 to G.711. If the
administered audio mode is auto and the administered bandwidth
is 112 kbps (56 k/channel) or 128 kbps (64 k/channel), the system
begins with the highest common audio, G.728. When the
administered bandwidth is greater than 128 kbps, the system
begins 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
operating audio modes.
“blank” = Blank until the first call is made from or to the endpoint.
Vid
Does it have required video capability and is it receiving video? -
y
,
c
,
e
,
n
,
blank
“y” = The endpoint has the required video capability and receives
video if the Chl, Aud, and Dat fields are
y .
“c” = The endpoint downgrades the conference’s video quality
from CIF to ACIF, or by decreasing the frame rate. The conference
video mode defaults to CIF, and if a QCIF-only endpoint joins 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 downgrade.
They do not upgraded until all endpoints disconnect from the
conference.
“e” = The endpoint does not declare video capability in its cap-set.
“n” = Audio only, not receiving video, due to an audio or data
problem.
“blank” = Audio add-on endpoints set the Vid field to
blank
.
Mlp
The relationship between the Control Link and the ESM (T.120
stack terminator), 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 did not have Still Frame Graphics capability.
The conference retains still frame graphics capability when a
non-compliant endpoint joins the conference.
“blank” = This endpoint never joins the conference.
