AFAIK the US ISDN uses only 56K chanels - or am I wrong ?

Depends on personal experiance - I got my hands on ISDN
equippment first in 1981, and used ISDN Parts for my own
design first in 1985 (to rebuild an /370 Mainframe into
a voice mail system). So, from this point it is clearly
older than 10 years, if you have (had) access to the
early development samples - but Even when thinking of
mass availability, ISDN and ISDN based technologies
already fit into the 10Y rule - at least here in Germany.
