7.3. ISDTRACE Utility

The ISDTRACE utility analyzes the binary trace files from the ISDN Diagnostics Program. When the utility is started with the ISDTRACE command, the utility translates the binary data into a text file. The converted text file identifies the commands issued, network responses, and binary values, as well as a description of those values.

To start the ISDTRACE utility (isdtrace), enter:

isdtrace infilename.log [<outfilename>] -p  

where:

• infilename.log is the saved binary file generated by the gc_StartTrace( ) function
• <outfilename> is the ASCII text readable trace of the D channel
• -p selects Primary Rate (PRI)

The ISDTRACE (isdtrace) utility creates a temporary file called isdtemp.log. The isdtemp.log file contains the hex information of the binary input file. The following shows an example of a file fragment with the translated data:
