No problem. The main CPU is assisted by HDLC controllers, and a fast and
wide data bus. And from a real world perspective, I have not heard of any
performance issues related to handling in an all isdn environment.

This sounds pretty hoakey. (did I spell that right?) Generally you can
request service for either alternating circuit-switched voice and data, or
circuit-switched data. Alternating circuit-switched voice and data permits
ISDN and modem calls. Circuit-switched data permits only ISDN calls.
Usually alternating circuit-switched voice and data commands a premium from
the telco. In either case, both services come with a telephone number. ;-)
