Prestige 100 and 100IH ISDN Router and Router/Hub
2-16 Hardware Installation and Setup
2.8.2 European (DSS1) & German (1TR6) ISDN Setup Menus
Switch Type
The only switch types supported in Europe are DSS-1 and 1TR6 (Germany only).
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. This option is available as Endgeraete Auswahl Ziffer (EAZ) for the1TR6
switch type.
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.
