Page 5 - Endpoint Call Status Information
This page summarizes such call-related status as per-channel join counts,
join/drop time, drop reason, drop code, and auxiliary bonding drop code. In
addition, it contains a drop code and software fields from the previous call. The
data on the page is always retained. The Endpoint Call Status Information section
groups together all call-related fields. The only new field in this section is Join
Count; all other fields are described in Screen 8-3
and Screen 8-4.
XR Transfer rate capabilities are statement about the speeds at which
the endpoint can operate over the current connection and operate a
Px64 Multiplex.
For a 384 kbps (H0) call, the endpoint sends its capabilities to
indicate 384 kbps support, which displays as 384. On a 336 kbps
call, the endpoint must signal 384 kbps support. If an endpoint does
not indicate support for 384 kbps on a 384/336 kbps conference, the
MCU provides Audio Only Communications Mode (ACOM). For a 2B
conference, the MCU sets the rate to 2x64, expecting the endpoints
to do likewise (64x2 is displayed; if this is not displayed, there is no
64x2 capability). Endpoints may occasionally take 2x64 (or the
current channel rate: 384, 768, 1472, 1536) out of their capability.
This is Mode 0 forcing and is part of normal procedures. The MCU
will provide AOCM if the endpoint does not signal support matching
the configuration of the conference.
AUD The audio fields are statements of the audio protocols that the
endpoint supports. 711m and 711a are PCM (G.711) and support Mu
and A-law, respectively, and at least one is required of endpoints.
The g728 field indicates whether G.728 is supported (LB_CELP). This
value depends upon the type of the endpoint and how that endpoint
is currently configured. The g722_48 field indicates endpoint support
for G.722 (7 kHz) at both 48 kbps and 56 kbps. Therefore, g722_48
indicates that the endpoint supports G.722 audio at both rates. The
g722_64 field indicates endpoint support for G.722 at 64 kbps in an
unframed (not supported by the MCU) mode.
LSD The LSD fields indicate the capabilities for Low Speed Data
conferencing.
HSD The HSD fields indicate the capabilities for High speed Data
conferencing.
MLP The MLP fields indicate the capabilities for Multi Layer Protocol Data
capabilities.
HMLP The HMLP fields indicate the conference’s capability for High Speed
MLP data conferencing.
