In this scenario, interfaces if0, if1, and if2 at the locate end place DCC calls to
interfaces if1, if2 and if3 at the remote end. If only one remote end is involved, use
the dialer number dial-number command to configure a dial string. If multiple
remote ends are involved, use the dialer route command to configure the dial
strings and destination addresses. As multiple interfaces are involved at the local
end, configure DCC parameters for them by configuring dialer circular groups. In
addition, you may configure PAP or CHAP authentication.
When placing calls, the physical interfaces in a dialer circular group use the IP
address of the associated dialer interface instead of its own. An ISDN BRI or PRI
interface itself can be regarded as a dialer circular group for its B channels. At the
same time, it can be assigned to other dialer circular groups.
After completing the basic DCC configurations, follow these steps to configure
multiple interfaces to place calls to one or multiple remote ends:
To do...
Enter system view
Create and enter dialer
interface view
Enable C-DCC
Configure the dial string and
destination address for calling
a remote end (repeat this step
if multiple remote ends are
involved)
Exit to system view
Enter physical interface view
Assign the physical interface
to the dialer circular group
corresponding to the dialer
interface

Required
Disabled by default.
Required
If only one remote end is
involved, you may use the
dialer number dial-number
command instead.

Required
The number argument in this
command must take the same
value assigned to the number
argument in the interface
dialer number command.
