I'm not sure if this is _the_ answer to the disconnect about ISDN,
Kilostream, etc.; but I believe Europe uses a different and
incompatible standard called Sonet, whereas the U.S. has the older
ISDN. For general background info, ISDN is generally a combination of
2 (64kbps) B channels and 1 (16K) D channel. Sonet uses a different
set of bandwidth characteristics. One of the primary drivers behind
ATM (aside from speed) is that it is able to bridge the comms barrier
between U.S. networks and Sonet.
