Field descriptions (status conference, page 2)
Sum Grp
The VD audio Level 1 (L1) and Level 2 (L2) summer group parts for each
assigned group (1-4). Summer parts are assigned only for conferences
with over 6 participants. When a conference operates at an audio mode
of 7 kHz (administered audio mode is 7 kHz, or auto with the bandwidth
greater than 128 kbps), the system allocates “primary” and “secondary”
L1 and L2 summer parts. Primary and secondary parts are allocated as
adjacent port slots on the same board. Status conferences display
primary summer ports. Secondary summer ports are one slot higher than
displayed primary summer ports.
Join Time
Time (in 24-hour notation) when the channel joins the conference.
Drop Time
Time (in 24-hour notation) when the channel disconnects. If the first
channel has a drop time, the endpoint is inactive. If a drop time exists
without a join time, the call disconnects without joining the conference.
Drop Reason
Channel’s disconnect because:
“2-pri” = Administration errors cause mismatches in primary-secondary
designation for cascade linking. This mismatch indicates that both MCUs
are administered as primaries (see “Cascading” for a description of
primary-secondary compatibility).
“2-sec” = Administration errors cause mismatches in primary-secondary
designation for a cascade link. This mismatch indicates that both MCUs
are administered as secondaries (see “Cascading” for a description of
primary-secondary compatibility).
“Agent” = The reservation agent causes the call to disconnect.
“Bandwidth” = A mismatch occurs between a call and the conference it
attempts to join.
“BondHshake” = Information channel parameters are unsupported or
invalid, parameter negotiations terminate out of sequence, timers expire
because secondary channels do not establish, or BONDing framing is
undetected for one of the other channels.
“Busy” = MCU detects that the conferee’s terminal equipment is busy.
This drop reason is detected by ISDN cause values (for example h0).
See “Dial-out” for a description of CPTR usage.
“Chair” = Chair Command Disconnect (CCD) or Chair Command Kill
(CCK) signals disconnects the endpoint.
“Conf End” = The conference ends when it reaches the stop time for a
reserved conference or an active conference converts to file.
