2.4.1 The Diagnostic Program
After you have installed your ISDN card, you are highly
recommended to use the diagnostic program to make sure the
ISDN card, its drivers and the ISDN line are all properly
installed and connected. To run the diagnostic program, please
follow these instructions:
1. Open the “Programs” folder on the “Start” menu and
click on the “ISDN Utility” item.
2. Click on the “Diagnostic Program” item, you will see the
following screen.
3. The IRQ and I/O Port hardware configuration is listed.
4. In the “Own ISDN Number” box, type in the subscriber
number of your own ISDN line.
5. 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.
