Aud Does it have the required audio capability? - y, c, e, blank
y the endpoint has the required audio capability. Audio add-on
endpoint always have the Aud field set to y once the endpoint has
joined the conference.
c this endpoint is PCM only and it changed the video quality of the
conference 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
starts out with the highest common audio of G.728. When the
administered bandwidth is greater than 128 kbps, the system starts out
with the highest common bandwidth of 7 kHz.
e A PCM-only endpoint that did not have the capability of supporting
the administered audio mode of G.728 (such as a data conference), or
G. 278/G.711 endpoint that did not have the capability of supporting
the administered audio mode of 7 kHz. Such endpoints operate with
PCM audio and interwork with the current operating audio mode.
blank the field is blank until the first call is made from/to the endpoint.
Vid Does it have the required video capability and is receiving video? - y, c,
e, n, blank
y the endpoint has the required video capability and should be
receiving video if the Chl, Aud, and Dat fields are y.
c means it downgraded the conference’s video quality - either from CIF
to ACIF or by decreasing the frame rate. The conference video mode is
set by default to CIF and if a QCIF-only endpoint joins the conference,
then the entire conference is made to operate in QCIF, with the video
clarity downgraded. Also, the conference frame rate is initially set to the
highest frame rate that can then be reduced by any endpoint. If the
conference video mode is not administered with upgrade capability,
then if the video parameters for a conference have been
“downgraded,” they are not “upgraded” until all endpoints disconnect
from the conference.
e means that the endpoint has not declared any video capability in its
cap-set.
n means audio only, not receiving video, possibly due to an audio or
data problem.
blank Audio add-on endpoint always have the Vid field set to blank.
Mlp The state of the Control Link to 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 value is always blank, indicating that the
Data Mode for the conference is none, and therefore, the data does not
apply, or the endpoint has never joined the conference.
