This may be late, but maybe it will help.

Of course. You need an upstream connection, whether you're a small ISP
using ISDN or a large ISP using a T1 or better, you still need a network
connection.

Yes. The "Dedicated" part involves the ISP though, not the TelCo.

The average ISDN user can use both B channels to connect to their ISP. An
incoming call can free up the second channel to let them receive a call
(Their connection will drop down to 64K). When the call is completed the
TA will add the 2nd channel back. You'd need a ISDN line with the right
options and an Terminal Adapter that support DBA (Dynamic Bandwidth
Allocation.)
This isn't really what you want to do anyway. You want all 128K available
at all times for your users.

ISP (Whatever they charge for 128K Dedicated ISDN)

YOU (Using whatever ISDN router you choose)

FreeBSD (Acting as a terminal server)

modem modem (etc)

POTS POTS (1 regular phone line for each modem, whatever telco charges.)
You could "get by" with NATD, but you might consider buying multiple IP's
from your ISP so you'd have an IP for the router, the FBSD box, and each
dialup. You'd have to work this out with them, including a domain name if
you want one.
