Configuration and Diagnostics of the IBM International ISDN PC Card
10 Configuration and
Diagnostics of the IBM
International ISDN PC Card
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.
No diagnostics tool is available for Windows 2000 Profes-
sional and Windows XP.
When you travel to another country outside Europe, it may be
necessary to change the adapter's 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.
In the USA, Canada, Australia, or New Zealand, the IBM In-
ternational 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 with the capability to
convert the U interface to a S/T interface.
