In Use
Is the endpoint participating in the conference or connecting to the
conference? -
y, c, e, f, n, blank.
“y” = The endpoint is in use and fully-connected on all media in an
active conference.
“c” = The endpoint is in use and fully-connected; however, the
endpoint changes the conference audio or video capability, or the
rate of the conference due to rate adaptation. This condition
requires analysis of this endpoint’s capabilities and mode fields to
identify the reduced capability.
“e” = The endpoint active, but has capability problems. The
endpoint lacks one of the required capabilities (Vid, Bhl, MLP) to
be a full participant. For MLP capabilities, see the “T120” field.
This condition requires analysis of this endpoint’s capabilities and
mode field to identify the missing capability.
“f” = The endpoint is active, but is not connected to all media. The
endpoint declared all required capabilities (channel/video/
audio/data) but is not fully-connected to all conference media. This
endpoint may be connecting, failed to connect, or is not a valid
video source. This condition requires analysis of this endpoint’s
capabilities and mode fields to identify the problem.
“n” = The endpoint connects then disconnects in a conference, or
unsuccessfully attempts to connect to a conference.
“blank” = Blank until the first call is made from or to the endpoint.
Enh BAS
Enhanced Basic Service Flag - n, y
“y” = The endpoint supports the enhanced BAS commands/caps;
“n” = The endpoint supports the basic BAS commands/caps.
Chl
Data on the quantify and quality of channels (transfer rate)? - y, e,
n, blank
“y” = The endpoint has the required number of channels.
“e” = The endpoint does not declare support for the correct
number of channels and cannot participate fully in the conference.
“n” = The endpoint declares the correct number of channels, but
not all channels join the conference, due to network or endpoint
problems.
“blank” = Audio add-on endpoints set the Chl field to blank.
