QSIG Trace
In addition to using the commands described previously, you can view the trace activity to help resolve
problems. The card level trace buffer contains very detailed event records and typically will not go back
further than an hour. To troubleshoot a problem, follow these steps:
1. Log on to the DTIC card (@conn X, where X = DTIC card slot number). At the qsig> prompt, enter
CL TRACE Enter
2. Reproduce the problem scenario.
3. Freeze the trace. Enter
TRA FRE Enter
4. List the trace to capture events related to the problem scenario:
LI TRA Enter
When you have the information you need, issue the CL TRACE command again to unfreeze the trace and
to clear the trace buffer.
.
To view a trace just after an event has occurred (before information has been overwritten) just use
the LI TRA command. Choose N when you are asked if you want to clear the trace queue.

01133645
Time Stamp
Time Stamp
-
The day, hour, minute, and second of the trace. For example, 01133645 is read as the first day of the
month (01), 13th hour, 36th minute, 45th second.
Device
-
The channel on the DTIC or the device (Data Channel = Dc, Card = Ca, Trunk = Tr) being traced.
Event Type
-
The activity that is happening. Typical events are
CCS Layer 3 RX, shows protocol packets received from the PBX
-
CCS Layer 3 TX, shows protocol packets sent to the PBX
-
CCS Layer 4 RX, shows commands received from the message server
-
CCS Layer 4 TX, shows event sent to the message server
-
Event Description and Data
-
For Layer 3 events, the trace shows the QSIG message type and relevant data extracted from the
information elements.
QSIG Trace Examples
The following two examples of trace activities provide a call scenario, the associated output from the CPT
trace, and the output from the card level trace reached by connecting to the DTIC (@CO X, where X =
DTIC card channel number).
