This page provides some basic ISDN settings such as enabling the ISDN port or not, MSN 
numbers and blocked MSN numbers, etc. 
 
ISDN Port 
Click Enable to open the ISDN port and Disable to close 
it. 
Country Code 
For proper operation on your local ISDN network, you 
should choose the correct country code. 
Own Number 
Enter your ISDN number. Every outgoing call will carry 
the number to the receiver. 
MSN Numbers for the Router 
MSN Numbers mean that the router is able to accept 
only number-matched incoming calls. In addition, MSN 
services should be supported by local ISDN network 
provider. The router provides three fields for MSN 
numbers. Note that MSN services must be acquired from 
your local telecommunication operators. By default, 
MSN function is disabled. If you leave the fields blank, 
all incoming calls will be accepted without number 
matching. 
Blocked MSN Numbers for the 
router
 
Enter the specified MSN number into the fields to 
prevent the router from dialing the specific MSN 
number.
