dialer numbers and destination addresses. Since the calls are originated from 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.

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 

 command. No dialer numbers for calling 

the remote ends are configured by default.

Perform the following configuration steps after the basic DCC configuration is 
implemented. As shown in the following figure, a local interface receives calls 
from multiple remote ends (the picture components of inverse color represent the 
routers irrelevant with the networking):

Figure 263   An interface receiving calls from multiple remote ends

As shown in Figure 263, 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 

 command to setup the user name and password 

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