6-6 ISDN Overview
Answering a Call Using MSN
When answering an incoming call, the call is first identified if the caller number matches the
Multiple Subscriber Number (MSN) settings.
The MSN supplementary service enables multiple ISDN numbers to be assigned to a single
ISDN BRI line. It allows the caller to select, through the public network, one or more distinct
terminals from a variety of terminal choices. The Model XM128 modem supports many different
communication protocols and two analog adapters.
Table 6-3 shows the commands used to assign
each of the ports to an ISDN number.
The command AT&ZI? can be used to display the MSN numbers. The factory default for these
numbers is UNASSIGNED.
