Drop Reason
(cont’d)
■
Pre-AnsDrop
The call disconnected before answer by an endpoint.
The cause of the disconnect may be the network, an endpoint, or a
terminal adapter. This drop reason is different from ‘No-answer,’ which
indicates that a 60-second timeout occurred while alerting. In this case,
the call drops before the 60-second timer has expired. Some busy
endpoints connected through terminal adapters display this behavior.
■
Resource
MCU could not provide resources (VC or MMI) when the call
arrived or lost the resources during the call. This could be due to them
being Out of Service, busied out by craft, or being used by system
maintenance. This drop reason could also occur if the DS1/MMI cable is
disconnected. If there was a resource problem when the call arrived, it
would get reorder (fast busy) and not get disconnected by the MCU.
■
Password
Either the user entered the wrong password or the audio
add-on user did not enter it within the specified time period. Note that the
audio add-on user gets one attempt to enter a correct password and
inter-digit timing for each digit (that is, about 10 seconds between digits).
■
System
An MCU restart (level 2) disconnected every call.
■
UIN-Inv
The user entered an invalid User Identification Number.
■
Unknown—
The system could not determine the cause of the disconnect.
■
Wrong-num
This dial-out drop reason occurs when the MCU detects the
wrong destination number was dialed. This drop reason is detected by
MCU CPTR resources SDN cause value. See “Dial-out” for details.
■
UCC
controller intentionally disconnected the endpoint.
Drop Code
A detail code complementing the Drop Reason (see above). Additional
bonding related information may be obtained from supplementary BONDing
Drop Codes described above.
AC Num
Administered Connection Number - from 1 to 128. AC number can be used to
further diagnose a problem 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). Because only
one audio encoder port is allocated per endpoint, it appears together with the
ESM data port in the endpoint’s channel 1 port slot position of the
Port
Aud/ESM
column.
For “UCC” endpoint type, the channel 1 port slot position displays the allocated
Call Classifier resource.
Ports ESM
The Expansion Service Module MMI data port. This field is always blank.
Ports BONDng
The MMI port used for BONDing for the channel.
Fr Err
Frame error counter. A circular hex counter (0-FF) to indicate the occurrence
of framing errors.
