Configuring DCC 717
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 command. In addition, when no dialer
interface is created, the physical interface does not belong to any dialer circular
group, and the default priority is assigned to physical interface 1, and this is added
to a dialer circular group.
Configuring multiple interfaces to receive calls from multiple remote ends
Perform the following configuration steps after the basic DCC configuration is
implemented. As shown in
Figure 231, multiple local interfaces receive calls from
multiple remote ends (the picture components of inverse color represent the
routers irrelevant with the networking):
Figure 231 Multiple interfaces receiving calls from multiple remote ends
As shown in Figure 231, the local interfaces interface1 (if0), if1, and if2 receive
DCC calls from the remote interfaces if1, if2 and if3. Since the local end is multiple
interfaces, the dialer circular group must be used to configure DCC. The user can
select to configure either PAP or CHAP authentication.
Use the local-user password command to configure the user name and
password permitted to dial in system view, and perform other configurations in
dial interface (physical or dialer interface) view.

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 command. If no dialer interface is
created then by default, the physical interfaces do not belong to any dialer circular
group.
