716 CHAPTER 51: CONFIGURING DCC
Figure 230 Multiple interfaces placing calls to multiple remote ends
As shown in Figure 230, the local interfaces interface0 (if0), if1, and if2 originate
DCC calls to the remote interfaces if1, if2 and if3. For allowing calls to originate
from multiple remote ends, the user must use the
dialer route command to
configure the dialer strings and destination addresses. For the calls to originate
from multiple interfaces, the dialer circular group must be used to configure DCC.
The user can select to configure either PAP or CHAP authentication.
Instead of using their own IP addresses, the physical interfaces in the dialer circular
group will use the IP address of the dialer interface in making the calls. The
argument number of the
dialer circular-group number command configured
in physical interface view must be the same as the number used in the
interface
dialer number
command configured in the view of the dialer interface to
properly associate the physical interface. ISDN BRI or PRI interface is regarded as
the dialer circular group for the B channels connected through either of these
interfaces. At the same time, they can be regarded as the physical interfaces by
other dialer circular groups.
Use the interface dialer command to create a dialer interface in global view,
add it to the specified dialer circular group through the
dialer circular-group
command, and perform other configuration processes in dialer interface view.
