Figure 1-4 An interface receiving a call from a remote end
As shown in the above figure, the single local interface interface0 (if0) receives a DCC
call from a single remote interface if1. Since the call is received by 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 1-5 Configure a local interface to receive calls from a remote interface
Enable C-DCC
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.
III. Configuring originating calls from an interface to multiple remote ends
Perform the following configuration steps after the basic DCC configuration is
implemented. As shown in the following figure, a local interface originates calls to
multiple remote ends (the picture components of inverse color represent the routers
irrelevant with the specific networking):
