Telephone 
Number(s) 

IDSN Data 

Enter the telephone number(s) assigned to your ISDN line by your telephone company. 
Some switch types only have one telephone number. Note that the router only accepts 
digits; please do not include ‘–’ or spaces in this field. This field should be no longer 
than 25 digits. 

Edit Advanced 
Setup 

Advanced Setup features are configured when you select Yes to enter Menu 2.1-ISDN 
Advanced Setup (see ahead). Refer to the Advanced Phone Services Chapter for 
detailed information. 

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to save 
your configuration, or press [ESC] at any time to cancel. 

Select Yes in the Edit Advanced Setup field of Menu 2 – ISDN Setup to display Menu 2.1 as shown later. 

The only switch available with your Prestige is DSS-1. 

The Calling Line Indication, or caller ID, determines whether the other party can see your number when 
you call. If set to Enable, the router sends the caller ID and the party you call can see your number; if it is 
set to Disable, the caller ID is blocked. 

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 router 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 router only. If you place a call from a device on 
either A/B adapter, you must dial the prefix by hand.
