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 c onference.
“c” = This PCM-only endpoint changes c onference video quality b y
changing the op erating audio from G.728 to G.711. If the ad ministered
audio mode is auto and the a dministered bandwid th 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 bandwid th is
greater than 128 kbps, the s ystem begins with the highest c ommon
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 end point.
Vid Does it have requi red video capability a nd is it receiv ing video? - y, c,
e, n, blank
“y” = The endp oint has the required vid eo capability and rec eives
video if the Chl, Aud, and Dat fields are y.
“c” = The endpoint downgrad es the conference’s video q uality from
CIF to ACIF, or by decreasing the frame rate. The con ference video
mode defaults to CIF, and if a QCIF-only endp oint joins the
conference, the entire confe rence operates in QCIF, with downgr aded
video clarity. The conferenc e frame rate is initially set to the highest
frame rate that can be reduc ed by any endp oint. If the conference
video mode is not admini stered with upgrade c apability, the video
parameters for a conference d owngrade. They do not upg raded until
all endpoints disc onnect from the conference.
“e” = The endpoint does not declare video capability in its cap-set.
“n” = Audio only, not receivin g video, due to an audio or data problem .
“blank” = Audio add-on endp oints set the Vid field to blank.
Mlp The relationship between the Control Link and the ESM (T.120 stack
terminator), the endpoint MLP data c apability, and the state of the
data connection in the T.120 stac k. This field defaults to blank,
indicating that the Data Mod e for the conference is none.
Gx “y” This endpoint ha s Still Frame Graphics capability .
“e” = This endpoint did not have Still Frame Graphics capability. The
conference retains still frame g raphics capab ility when a
non-compliant endp oint joins the conference.
“blank” = This endpoint never joins the conferenc e.
