Drop Reason
(cont’d)
“Pre-AnsDrop” = The call disconnects before an endpoint answers. The
network, an endpoint, or a terminal adapter may cause the disconnect.
This drop reason differs from ‘No-answer,’ which indicates that a
60-second timeout occurs during alerting. In this case, the call drops
before the 60-second timer expires. Some busy endpoints connected
through terminal adapters display this behavior.
“Resource” = MCU cannot provide resources (VC or MMI) when the call
arrives or loses the resources during the call. This can occur when they
are Out of Service, busied out by craft, or in use by system
maintenance. This drop reason can also occur if the DS1/MMI cable
disconnects. If a resource problem exists when the call arrives, it gets a
reorder (fast busy) and the MCU does not disconnected it.
“Password” =The user entered a wrong password or the audio add-on
user did not enter it within the specified time period. The audio add-on
user has one attempt to enter a correct password and has about 10
seconds between digits (inter-digit timing).
“System” = MCU restarts (level 2) disconnect all calls.
“UIN-Inv” The user enters an invalid User Identification Number.
“Unknown” = The system cannot determine the disconnect cause.
“Wrong Num” The MCPTR resources SDN cause value detects an
incorrectly-dialed destination number. See “Dial-out” for details.
“UCC” = The controller intentionally disconnects the endpoint.
AC Num Administered Connection Number. (1–128) AC numbers further
diagnose problems by combining status conference information with the
status administered connection command, and data stored in error
and alarm logs.
Ports Trunk The data endpoint used by the channel.
Ports Video The MMI port for the channel.
Ports Aud If the endpoint type is not “UCC,” the VC audio encoder port (which is
always paired to a decoder port) for the channel (only the first channel).
appears together with the ESM data port in the endpoint’s channel 1
port slot position of the Port Aud/ESM column. For “UCC” endpoints,
channel 1 port slot positions display allocated Call Classifier resources.
Ports ESM Expansion Service Module MMI data port. This field defaults to blank.
Sum Grp Endpoint’s assigned summer group number. The summer group port
assignments are on screen 1.
