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 can 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.
Default Answer Profile for Dial-in Connections
The Netopia R2020 Dual Analog Router can answer calls as well as initiate them. To answer calls, the Netopia
R2020 uses a Default Answer Profile. The Default Answer Profile controls how incoming calls are set up,
authenticated, filtered, and more.
How the Default Answer Profile works
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.
If an incoming call is not required to match a connection profile, and fails to do so, it is accepted as a standard
IP connection. Accepted, unmatched calls adopt the call parameter values set in the Default Answer Profile.
To determine the call parameter values that unmatched calls will adopt, customize the Default Answer Profile
parameters in the Default Answer Profile screen.
Customizing the default profile
You can customize the Netopia Router’s default profile in the Default Answer Profile screen.
