As shown in Figure 230, the local interfaces interface0 (if0), if1, and if2 originate DCC calls to the remote interfaces if1, if2 and if3. For allowing calls to originate from multiple remote ends, the user must use the dialer route command to configure the dialer strings and destination addresses. For the calls to originate from multiple interfaces, the dialer circular group must be used to configure DCC. The user can select to configure either PAP or CHAP authentication.

Instead of using their own IP addresses, the physical interfaces in the dialer circular group will use the IP address of the dialer interface in making the calls. The argument number of the dialer circular-groupnumber command configured in physical interface view must be the same as the number used in the interface dialer number command configured in the view of the dialer interface to properly associate the physical interface. ISDN BRI or PRI interface is regarded as the dialer circular group for the B channels connected through either of these interfaces. At the same time, they can be regarded as the physical interfaces by other dialer circular groups.

Use the interface dialer command to create a dialer interface in global view, add it to the specified dialer circular group through the dialer circular-groupcommand, and perform other configuration processes in dialer interface view.
