1.11 The Diagnostic Program
After you have installed your MISTRAL USB, you are highly
recommended to use the diagnostic program to make sure
the ISDN TA, its drivers and the ISDN line are all properly
installed and connected. To run the diagnostic program
please follow these instructions:
• Open the Programs folder on the Start menu and
click on the ISDN Utility program folder.
• Click on the Diagnostic Program item to start the
program.
• In the Own ISDN Number box, type in the
subscriber number of your own ISDN line.
• Press Loopback Test to begin the diagnostic
procedure. It will make a call from the B1 channel
that returns through the B2 channel. The D and B
channels will be tested for line integrity.
• Please Troubleshooting if you see any error or
warning message.
