3.13. ISDN Trace

ISDNtrace provides the ability to track Layer 3 (Q.931) messages on the ISDN D-channel. ISDNtrace prints the messages on the screen in real time. This trace information also can be captured into a file.

Operating Systems: Windows, Linux

Command Line: isdntrace [parameter_list]

The ISDNtrace utility uses the following command line parameters:

Parameter	Description
-b<n>	The number of the board on which you want to run the utility (required). Use the Listboards utility to obtain the board number.
-d<n>	The D-channel number (trunk number) on the above board (required)
-f<file>	The filename into which the trace can be captured (required to save the trace in a file)

Example: This example runs ISDNtrace on board 0, D-channel (trunk) number 1 and captures the trace in a file named logfile.txt:

isdntrace -b0 -d1 -file logfile.txt
