Drop Reason
(cont’d)
“Pre-AnsDrop” = The call disconnects 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 that are
connected through terminal adapters display this behavior.
“Resource” = MCU cannot provide resources (VC or MMI) when calls
arrive or lose their resources during the call. Calls can lose resources
when they are Out of Service, busied out by craft, or in use by system
maintenance. If the DS1/MMI cable is disconnected, this drop reason
can also occur. If a resource problem exists when the call arrives, it
gets reorder (fast busy) and is not disconnected by the MCU.
“Password” = The user enters a wrong password or the audio add-on
user does not enter it within the specified time period. The audio
add-on user gets 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” = Users enter invalid User Identification Numbers.
“Unknown” = The system cannot determine the disconnect cause.
“Wrong-num” = The MCU CPTR resources SDN cause values detect an
incorrectly-dialed destination number. See “Dial-out” for details.
“UCC” = The controller intentionally disconnects the endpoint.
Drop Code A detail code complementing the Drop Reason. Additional
bonding-related information is available from the supplementary
BONDing Drop Codes described above.
AC Num Administered Connection Numbers. (1–128) AC numbers can further
diagnose problems by combining status conference information with
the status administered connection command, and data stored in the
error and alarm logs.
Ports Trunk The data endpoint that the channel is using.
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,
the channel 1 port slot position displays allocated Call Classifier
resources.
Ports ESM Expansion Service Module MMI data port. This field is always blank.
Ports BONDng The MMI port used for channel BONDing.
Fr Err Frame error counter. A circular hex counter (0-FF) to indicates framing
error occurrences.
