P100IH ISDN Router

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 (DSS1) 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.

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.

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 Call Routing is either A/B Adapter 1 or 2, then the Prestige uses Global Analog Call to decide how to handle global calls. If you set Global Analog Call to Accept, then global calls are routed to the port according to the Analog Call Routing setting; if you set Global Analog Call to Ignore, then the Prestige ignores all global calls. If Analog Call Routing is Ignore to begin with, then all analog calls, including global calls, are ignored.

PABX Outside Line Prefix

A PABX (Private Automatic Branch eXchange) generally requires you to dial a number (a single digit in most cases) when you need an outside line. If your Prestige is connected to a PABX, enter this number in PABX Outside Line Prefix, otherwise, leave it blank.

Please note that the PABX prefix is for calls initiated by the Prestige only. If you place a call from a device on either A/B adapter, you must dial the prefix by hand.

Outgoing Calling Party Number

If this field is not blank, the Prestige will use its value as the calling party number for "ISDN Data", "A/B Adapter 1" and "A/B Adapter 2" outgoing calls. Otherwise, the individual entries for "ISDNData", "A/B Adapter 1" and "A/B Adapter 2" will be used as the calling party number. You only need to fill in this field if your switch or PABX requires a specific calling party number for outgoing calls, otherwise, leave it blank. If you need to override the individual calling party number, enter Command Interpreter mode and issue the command:
