Local end
(Multiple interface)
Figure 1-8 Multiple interfaces receiving calls from multiple remote ends
As shown in the above figure, 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 local-user in system view and password in local user view to configure the
username and password of a user that is allowed to dial in, and perform other
configuration tasks in dial interface (physical or dialer interface) view.
Table 1-9 Configure multiple local interfaces to receive calls from multiple remote ends
Enable C-DCC
Create a dialer interface and enter the
dialer interface view
Delete the existing configuration of the
dialer interface
Add a physical interface to the specified
dialer circular group
Delete the physical interface from the
specified dialer circular group
By default, C-DCC is enabled on ISDN BRI and PRI interfaces, but disabled on other
interfaces (Serial, Asynchronous, AUX, etc.) and the user should manually configure
the dialer enable-circular command. If no dialer interface is created then by default,
the physical interfaces do not belong to any dialer circular group.

1.2.3 Configuring RS-DCC

Each RS-attribute set consists of a dialer interface, the attributes of the interface, and a
dialer bundle. Specifically,
Only one dialing number can be defined for a dialer interface. Since this dialing
number has its own dial attributes set, all the calls originated by dialing this
number can use the same DCC attribute parameters (such as dialing rate).
