This is not quite right anymore. The so called EuroISDN is now DSS-1, which is
also used by many countries outside europe. I think Japan is one of them. Also
is the hardware of the most cards sold in europe, very generic and there should
be no problem to use them everywhere (where ISDN exists), it is a matter of the
driver software. One example is a SGI Indy which has a built in ISDN interface,
based on the same chip used in europe. The SGI Indy has support for >5
different ISDN protocols. The same you get for better PC ISDN cards.
