Aud Does it have the required audio capability? - y, c, e, blank
y the endpoint has the requi red audio cap ability. Audio add -on
endpoint always have the Aud field set to y once the end point has
joined the conference.
c this endpoint is PCM only and it c hanged the video q uality of the
conference by c hanging the operating audio from G.728 to G.711. If
the administered audio mod e is auto and the administer ed bandwid th
is 112 kbps (56 k/channel) or 128 kbps (64 k/channe l), the system
starts out with the highest common aud io of G.728. When the
administered band width is greater than 128 kb ps, the system starts
out with the highest common b andwidth of 7 kHz.
e A PCM-only endpoint that did no t have the capability of sup porting
the administered audio mod e of G.728 (such as a data conference),
or G. 278/G.711 endpoint that d id not have the capab ility of
supporting the ad ministered audio mod e of 7 kHz. Such endpoints
operate with PCM audio and interwork with the c urrent operating
audio mode.
blank the field is blank until the first c all is made from/to the
endpoint.
Vid Does i t have the required video capabi lity and is receiving v ideo? - y,
c, e, n, blank
y the endpoint has the requi red video cap ability and should b e
receiving video if the Chl, Aud, and Dat fields are y.
c means it downgraded the conference’s vid eo quality - either from
CIF to ACIF or by decreasing the frame rate. The c onference video
mode is set by default to C IF and if a QCIF-only endpoint joins the
conference, then the entire co nference is made to oper ate in QCIF,
with the video clarity d owngraded. Also, the c onference frame rate is
initially set to the highest frame rate that can then b e reduced b y any
endpoint. If the conferenc e video mode is not ad ministered with
upgrade c apability, then if the video p arameters for a conference
have been “downg raded,” they a re not “upgrad ed” until all end points
disconnect from the c onference.
e means that the endpoint has not d eclared any video c apability in its
cap-set.
n means audio only, not receiving video, possibly d ue to an audio or
data problem.
blank Audio add-on end point 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 cap ability, and the state of the dat a connection in
the T.120 stack. This field value is always blank, indic ating that the
Data Mode for the conference is none, a nd therefore, the data does
not apply, or the endp oint has never joined the confer ence.
