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
