Delete the destination address(es) and
dialer number(s) for calling one or more
remote ends
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-circular
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.

(Single interface)

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
to allow for dial in the system view, and then perform other configuration steps in
the dial interface (physical or dialer interface) view.

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):
