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

Figure 261   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.

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. 

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):

Figure 262   An interface placing calls to multiple remote ends

As shown in the above figure, a single local interface interface0 (if0) originates 
DCC calls to the remote interfaces if1 and if2. Since calls are originated to multiple 
remote ends, the user must use the

 command to configure the
