2-40 Reference GuideHow the default profile works for a switchedcircuitThe Default Profile works like a guard booth at the gate to yournetwork: it scrutinizes incoming calls. Like the guard booth, thedefault profile allows calls based on a set of criteria that you define.The main criterion used to check calls is whether they match one ofthe connection profiles already defined. If PAP or CHAP authenticationis being used, the default profile checks that the incoming call’s nameand password/secret match the receive name and password/secretof a connection profile. If PAP or CHAP is not being used, an incomingcall is matched to a connection profile using the remote network’s IPaddress (that is, the caller is defined as the destination of a particularconnection profile).If an incoming call is matched to an existing connection profile, thecall is accepted. All of that connection profile’s parameters, except forauthentication, are adopted for the call.You could set up the default profile to allow calls in even if they fail tomatch a connection profile. Continuing the guard booth analogy, thiswould 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, andfails to do so, it is accepted as a standard IP connection. Accepted,unmatched calls adopt the call parameter values set in the defaultprofile.To determine how which call parameter values unmatched calls willadopt, customize the default profile parameters in the Default Profilescreen.Customizing the default profileYou can customize the Netopia Router’s default profile in the DefaultProfile screen.
