Configuration Guide
As shown in the above figure, a single local interface interface0 (if0) originates DCC
calls to the remote interfaces if1 and if2. Since calls are originated to multiple remote
ends, the user must use the dialer route command to configure the dialer numbers and
destination addresses. Since the calls are originated from a single local interface, the
dialer circular group can be used to configure DCC. The user can select to configure
either PAP or CHAP authentication.
Perform the following configuration in dial interface (physical or dialer interface) view.
Table 1-6 Configure a local interface to originate calls to multiple remote ends
Enable C-DCC
Configure destination address(es) and
dialer number(s) for calling one or more
remote ends
Delete the destination address(es) and
dialer number(s) for calling one or more
remote ends
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 numbers for calling the remote ends
are configured by default.
IV. 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 the following figure, a local interface receives calls from
multiple remote ends (the picture components of inverse color represent the routers
irrelevant with the networking):

As shown in the above 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
