Euro ISDN is not Euro ISDN anymore. After the Japanese adopted it, the
E-DSS 1 protocol was renamed DSS 1 ; and currently DSS 1 becomes more and
more popular in the US. I think many US residents can get DSS 1 from their
phone company.

There are several of these ISDN adaptors available, at least in Germany;
for example the Elink devices from EEH Datalink in Radevormwald; and a
device from Elsa in Aachen. They have a serial interface and a Hayes-like
command set. I'm pretty sure they work with BSD, though I haven't tried
them out yet. They got good reviews in the computer magazine c't.
