2.8European ISDN Setup Menus

Menu 2 is for you to enter the information about your ISDN line. Please note that the Prestige only accepts digits in phone number fields; please do no include ‘-‘ or spaces in these fields.

2.8.1 Switch Type

The only switch type supported in Europe is DSS-1.

2.8.2 MSN and Subaddress

Depending on your location, you may have Multiple Subscriber Number (MSN) where the telephone company gives you more than one number for your ISDN line. You can assign each number to a different port, e.g., the first number to data calls, the second to A/B adapter 1 and so on. Or the telephone company may give you only one number, but allow you to assign your own subaddresses to different ports, e.g., subaddress 1 to data calls and 2 to A/B adapter 1.

2.8.3 Incoming Call Routing

The Incoming Phone Number Matching setting governs how incoming calls are routed. If you select Multiple Subscriber Number (MSN) or Called Party Subaddress, a call (either ISDN data or analog) is routed to the port that matches the dialed number; if no match is found, the call is dropped.

If you select Don’t Care, then all data calls are routed to the Prestige itself. Analog calls, however, are routed to either A/B adapter 1 or 2, or simply ignored, depending on the Analog Call Routing field.

2.8.4 Global Calls

A global call is an incoming analog call where the switch did not send the dialed number. This happens most often when the call originates from an analog telephone line.

If you specify explicit matching, i.e., Incoming Phone Number Matching is either MSN or Called Party Subaddress, then global calls are always ignored. If it is Don’t Care and Analog
