Ordering, Installing, and Configuring the ISDN Line
3Com has determined the optimal ISDN line configurations
for the 3Com Impact digital modem and has provided that
configuration data to many telephone companies. To simplify
the ordering process for an ISDN digital line, use the following
simplified ISDN ordering code:
3ComA * J6
If your digital modem has an internal analog fax modem
(Models 3C872 and 3C877), then two directory numbers
(telephone numbers) will be required to allow a voice call and
a fax modem call to occur at the same time. When you tell the
telephone company the ISDN ordering code (3ComA * J6) let
the representative know that you will need two directory
numbers.
