Справочник Пользователя для Netopia R3100

You can customize the Netopia Router’s default profile in the Default Answer Profile screen under the WAN 
Configuration menu.

1.

Select Default Answer Profile in the WAN Configuration screen. Press Return. The Default Profile screen 
appears.

2.

To enable CNA-authentication, select Calling Number Authentication in the Default Answer Profile screen 
and choose one of the following settings:

Ignored: Calling Number Authentication (CNA) is not in effect.

Preferred: This is the default setting. Authentication is attempted if the calling number is available. If 
authentication fails, or the calling number is not available, the call proceeds as usual and the caller may 
still connect successfully. Use this setting if you expect to receive both regular and CNA-authenticated 
calls.

Required: Authentication is attempted if the calling number is available. If authentication fails, or the 
calling number is not available, the Netopia R3100 disconnects the caller. Use this setting if you require all 
calls to be CNA-authenticated.

Calling Number Authentication (CNA), is an application of CallerID. It is a method of verifying that an 
incoming call is originating from an expected site. Using CNA, you can increase the security of your network 
by requiring that callers not only possess the correct PPP authentication information, but also are calling 
from a par ticular physical location.
