76: DCC C

ONFIGURATION

By default, Circular DCC is enabled on ISDN 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 1 if the physical interface is added to the 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 the following figure, multiple local interfaces receive
calls from multiple remote ends (the picture components of inverse color represent
the routers irrelevant with the networking):

Figure 265 Multiple interfaces receiving calls from multiple remote ends

As shown in Figure 265, 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.

Create a dialer interface and enter
the dialer interface view.
