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.
