Figure 1-3 An interface placing a call to a remote end

As shown in the above figure, the single local interface interface0 (if0) originates a DCC

call to the single remote interface if1. Since the call is originated to a single remote end,

the dialer string can be configured using the dialer number or dialer route command.

When the call is originated from the single interface at the local end, the dialer circular

group can be used to configure the DCC. The user can select to configure either PAP or

CHAP authentication on the interface.

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

Table 1-4 Configure a local interface to originate calls to a remote end

Enable C-DCC

Configure a dialer number for calling a remote end

Delete the dialer number for calling the remote end

By default, C-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-circular command. No dialer number for calling the remote end is

configured by default.

II. Configuring 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):
