Figure 3-7. Multiple Subscriber Numbers screen
2.
Type in the MSN numbers of the incoming calls in the appropriate field.
This dialog box allows you to assign telephone numbers to specific incoming data calls. In
order to make use of this feature, you must subscribe to Multiple Subscriber Number (MSN)
service from your local PTT. If a number has been specified for any of the B channel protocol
fields (X.75, PPP, V.110, or V.120), any incoming data call matching that number will
automatically cause the TA to use the corresponding protocol. If a number has been entered in
the ISDN Data Multi-Auto field, the Model XM128S modem automatically detects the
appropriate B channel protocol.
The Multiple Subscriber Numbers screen allows you to set the default analog port when the
MSN is not matched. If an incoming call does not match one of the defined numbers, the call
will be automatically routed to the default port.
