Jackie, there are people on this list who are far better equipped than I
to respond to this question (are you listening, Rob and Mark); however, to
the best of my understanding, it sounds like your ISDN connectivity would
be used to dial in to what we call an IMUX (a type of multiplexer) that
would route your signals to the compressed video videoconferencing
equipment being used.  For example, you may have either VTel equipment and
would use your ISDN dialup to connect to another user somewhere.....this
has a cost (fairly high, I might add, in some places) associated with it.

What I have proposed is simple, ordinary Internet data videoconferencing.
It's much jerkier than the compressed video signals run through systems
like VTel.

There's so much more to this issue, but I hope my few scattered words will
help some.  If you have a direct connection to the Internet for your
computer, then you're in the game.  If you are restricted to dialup,
through a modem, then your chances of obtaining satisfactory connection is
far less.
