First, you must understand that the ISDN is still in the definition process --
there are still holes in the definition and there are conflicts between some of
the definitions generated by 2 or 3 main groups who are defining it.

Secondly, because the lower layers are still being defined, there is very
little printed matter available in the form of summaries, especially as it
applies to the user interface.

Every effort is being made during the definition process to not define the
user interface.  This is being left to the manufacturers (that's how they
distinguish their equipment from that of another manufacturers').  The
definition of the ISDN is being accomplished in a form which hopefully
maximimizes the extent to which existing applications can be implemented in
or interfaced to the ISDN with their user interface intact.  

Last, but not least, manufacturers understand that in order sell ISDN
equipment, such equipment will have to be compatible with the current Public
Switched Network and with functions provided by and within it;  therefore,
initially (and probably for a very long time) ISDN equipment will be
compatible with existing facilities and functions (if you plan to be able to
sell it).
