Chapter 6:
Testing and troubleshooting

Normally, your Trust Communicator ISDN 128 Internal should
work immediately after installation. If you encounter
problems, test the hardware first and then the ISDN line. If
both tests are run successfully, the problem is probably due to
wrong settings for the modem or network. If one or both tests
gives an error, you will have to solve this first before a
successful connection can be made.

6.1 Testing the hardware

This test is intended to check that your board's components
are operational. Test as follows:

1.  Point to the ‘Trust ISDN Monitor’ icon on the Windows 95

task bar, while clicking the right mouse button.

2. Select ‘Properties’.

3.  Click ‘Test Hardware’. A status window shows the

condition of various chips on your board.

4.  The hardware is working fine if the screen from figure 10 is

displayed.
