Spot on.
A single ISDN B channel in the US is 56K. This fact *and another* make Euro
and US ISDN equipment incompatible.
ISDN in Europe is terminted in the ISDN connection in your equipment (S/T)
whereas in the US, it is termiated outside the premises (NT1).
All due to the different legislation and time periods from when ISDN was
being rolled out around the world...
However, a Euro ISDN can call and connect to a US ISDN and vice versa
without any problems.
Plus, a lot of US telcos are now rolling out 64K ISDN B channels, as they
get more bandwidth for the same charge, in the same way, some UK telcos will
provide you with US rated data lines as well....
