By default, Circular DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other interfaces (serial, asynchronous, AUX, etc.) and the user should manually configure the dialer enable-circularcommand. No dialer numbers for calling the remote ends are configured by default.

Configuring an interface to receive calls from multiple remote ends

Perform the following configuration steps after the basic DCC configuration is implemented. As shown in Figure 229, a local interface receives calls from multiple remote ends.

As shown in this figure, the single local interface interface0 (if0) receives DCC calls from the remote interfaces if1 and if4. Since the local end is a single interface, the dialer circular group can be used to configure DCC. The user can select to configure either PAP or CHAP authentication.

Use the local-user password command to set up the user name and password to allow for dial in the system view, and then perform other configuration steps in the dial interface (physical or dialer interface) view.

Operation	Command
Enable Circular DCC	dialer enable-circular

By default, circular DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other interfaces (serial, asynchronous, AUX, etc.) and the user should manually configure the dialer enable-circularcommand. No authentication parameters or dial-in user information are configured by default.

Configuring multiple interfaces to originate calls to multiple remote ends

Perform the following configuration steps after the basic DCC configuration is implemented. As shown in the following figure, multiple local interfaces originate calls to multiple remote ends (the picture components of inverse color represent the routers irrelevant with the networking):
