10.Configuration and diagnostics of the IBM International ISDN PC Card

Note: No diagnostics tool is available for Windows 2000 and Windows XP.

This chapter briefly describes how to change the D-channel protocol (also called the switch type), how to change MSNs, and how to diagnose problems with the adapter.

When you travel to another country outside Europe, it might be necessary to change the adapter D-channel protocol, also known as the switch type. The IBM International ISDN PC Card supports the following D-channel protocols:

Euro-ISDN (DSS1)

NI-1

5ESS

Euro-ISDN is used all over Europe, Australia and New Zealand. NI-1 and 5ESS are North American switch types.

Note: In the United States of America, Canada, Australia, or New Zealand, the IBM International ISDN PC Card cannot be connected directly to the ISDN line. To use this adapter in these countries, an NT1 adapter is required to convert the U interface provided in these countries to the S/T interface used in Europe.

Make sure that you purchase an NT1 adapter with the capability to convert the U interface to a S/T interface.
