714CHAPTER 51: CONFIGURING DCC

As shown in this 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. You can choose to configure either PAP or CHAP authentication.

Perform the following configuration in dial interface (physical or dialer interface) view.

Table 746 Configure a local interface to receive calls from a remote interface

Operation	Command
Enable Circular DCC	dialer enable-circular

By default, Circular DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other interfaces (serial, asynchronous, AUX, etc.) and you should manually configure the dialer enable-circularcommand.

Configuring originating calls from an interface to multiple remote ends

Perform the following configuration steps after the basic DCC configuration is implemented. As shown in Figure 228, a local interface originates calls to multiple remote ends (the picture components of inverse color represent the routers irrelevant with the specific networking):

Figure 228 An interface placing calls to multiple remote ends

	if1		Remote end A
			Single/Multiple interface(s)
if0			Router
	if2		Remote end B
Local end
			Single/Multiple interface(s)
(Single interface)
			Router
Router		if3
			Remote end C
			Single/Multiple interface(s)
			Router

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 dialer route command to configure the dialer numbers and destination addresses. Since the calls originate 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.
