Maintenance Commands and Trouble-Clearing Aids

Drop Reason
Channels disconnect because:
“2-pri” = Administration errors cause mismatches in primary-
secondary designations for cascade links. 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 designations for cascade links. This mismatch shows
that both MCUs are administered as secondaries (see
“Cascading” for a description of primary-secondary
compatibility).
“Agent” = Reservation agents cause calls to disconnect (for
example, agents change connected dial-out destination
numbers).
“Bandwidth” = Mismatches occur when bandwidths of calls and
the conferences they attempt to join are inconsistent.
“BondHshake” = Unsupported Information channel parameters
or invalid, parameter negotiations that terminate out of
sequence, timers that expire because secondary channels do
not establish, or BONDing framing that goes undetected for
another channels.
“Busy” = The MCU detects that the conferee’s terminal
equipment is busy. An ISDN cause value detects this drop
reason (for example h0). See “Dial-out” for a description of
CPTR usage.
“Chair” = Chair Command Disconnect (CCD) or Chair
Command Kill (CCK) signals disconnect the endpoint.
“Conf End” = The conference ends when the stop time is
reached for a reserved conference or an active conference
converts to file.
