As shown in this figure, the single local interface interface0 (if0) originates a DCC call to the single remote interface if1. Since the call originates at a single remote end the dialer string can be configured using the dialer number or dialer route command. When the call originates from the single interface at the local end, the dialer circular group can be used to configure the DCC. The user can choose to configure either PAP or CHAP authentication on the interface.

Perform the following configuration in dial interface (physical or dialer interface) view.

Table 745 Configure a Local Interface to Originate Calls to a Remote End

Operation	Command
Enable Circular DCC	dialer enable-circular
Configure a dialer number for calling a	dialer number [ dial-number]
remote end
Delete the dialer number for calling the	undo dialer number
remote end

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 number for calling the remote end is configured by default.

Configure an interface to receive calls from a remote end

Perform the following configuration steps after the basic DCC configuration is implemented. As shown in the following figure, a local interface receives a call from a single remote end (the picture components of inverse color represent the routers irrelevant with the networking):
