information on how to use the optional AppleTalk feature set.

For external modem applications, the Data Rate pop-up offers a variety of clock rates from 9600 to 
230 Kbps. The default is 57.6 kbps.

You may also specify the Modem Init String for your modem and the Directory Number of the telephone 
line connected to the third por t.

Note: If you change the modem init string, you must restar t the system. From the Main Menu, go to 
Utilities & Diagnostics and select Restar t System. The router will reboot, and your changes will be in effect.

The Netopia R2121 Dual Analog Router

can answer calls as well as initiate them. To answer calls, the Netopia 

R2121 uses a Default Answer Profile. The Default Answer Profile controls how incoming calls are set up, 
authenticated, filtered, and more.

The Default Answer Profile works like a guard booth at the gate to your network: it scrutinizes incoming calls. 
Like the guard booth, the Default Answer Profile allows calls based on a set of criteria that you define.

The main criterion used to check calls is whether they match one of the Connection Profiles already defined. If 
PAP or CHAP authentication is being used, the default profile checks that the incoming call’s name and pass-
word/secret match the receive name and password/secret of a Connection Profile. If PAP or CHAP is not being 
used, an incoming call is matched to a Connection Profile using the remote network’s IP address (that is, the 
caller is defined as the destination of a par ticular connection profile).

If an incoming call is matched to an existing Connection Profile, the call is accepted. All of that Connection 
Profile’s parameters, except for authentication, are adopted for the call.

You could set up the Default Answer Profile to allow calls in even if they fail to match a Connection Profile. 
Continuing the guard booth analogy, this would be like removing the guards or having them wave all calls in, 
regardless of their source.
