Okay, my recent reading of Telecom has raised many questions.  Could some
persons who know provide the following info:

Is this new "ID the caller" beta-test service handled by / the same as /
utterly unrelated to / etc ISDN?

Exactly, and by this I mean electrically down to the bit level, how does
the beta-test service [I forget its name offhand] work?  How is the number
of the caller passed to the recipient's equipment, and what is required on
the called end to display it?  [I'm thinking "build my own" here...]

It seems to me that for this service to work the caller must be in an office
where the service is being tested too.  Present ["normal"] offices wouldn't
have the capability to pass a packet containing the caller's number to the
destination end, right?  Is this packet the same kind of thing an office
passes to a TSPS on 0+ calls?  Grubby internal details, please??

And finally, where is the documentation for ISDN protocols located?
