ISDN Utility and Diagnostic Program
The ISDN Utility includes helpful programs for the USB ISDN
TA, such as a diagnostic program, an uninstallation program,
and an on-line manual.
After Windows installs the driver of your ISDN TA, the ISDN
Utility may be installed automatically. If the ISDN Utility is not
installed, you may install it from the installation CD.
You are highly recommended to run the diagnostic program to
make sure the USB ISDN TA, its drivers and the ISDN line are
all properly installed and connected. Please follow these
instructions:
1. Open the “P
rograms” folder on the “Start” menu and click
on the “ISDN Utility” program folder.
2. Click on the “
Diagnostic Program
” item to start the program.
3. In the “Own ISDN Number” box, type in the subscriber
number of your ISDN line.
