Diagnosing Digital Trunk Issues
The following table lists key maintenance commands that you can use to diagnose issues with
digital trunks. Note that the following table does not provide a comprehensive listing of all
problems, but it does cover the most commonly encountered problems.
Table 69: Maintenance commands for diagnosing digital trunk issues
Symptom Commands Description
Any problem edt show link config all
edt show framer config all
edt show link info
edt show vdsu table
These commands output generic configuration
information about the embedded digital trunks.
From the output of these commands, you can tell
how the trunks are configured. Use these
commands to quickly identify any differences
between the perceived and actual configuration
of the trunks.
Link alarms - Part 1
(System unable to seize
trunks or trunks are
unavailable, network
synchronization issues,
and so forth)
edt show framer stats all
edt show framer regs all
Outputs the statistical registers of the framers
and the register settings. The outputs show exact
the physical issue that is affecting the framer.
You may have to dump
the “framer stats” more than once as these
registers change over time. Collect this
output in association with the output from the
“dtstats read”, “net state” and “show
faults digital links” maintenance commands.
Note: The output from these commands must be
interpreted by Mitel Software Design.
Link alarms - Part 2
(Trunks not in idle when
there are no calls up)
edt show vdsu alarms <plid>
edt show vdsu channel <plid>
Shows the current digital trunking alarms and
channel status. Use this command in
conjunction with “dtstats read” and “state”
commands.
Note: The output from these commands may
need to be interpreted by Mitel Software Design.
Outgoing or incoming calls
rejected
edt trace vdsu namnum Outputs the calling/called number and calling
name of the call. It also displays
the reason an ISDN call was disconnected (may
be different than what is displayed
on a set). Use this command to verify that the
ARS is setup correctly and that the
correct number of digits are being sent or
received.
