DCC Configuration 163
Configuring an interface to receive calls from multiple remote ends
As shown in the following figure, an interface at the local end receives calls from
multiple remote ends (the components in inverse color represent the routers
irrelevant to the networking):
Figure 18 Network diagram for an interface to receive calls from multiple remote ends
In this scenario, a single local interface interface0 (if0) receives DCC calls from
multiple remote interfaces including if1 and if4. As only one interface is involved
at the local end, you may configure DCC parameters for the interface by
configuring a dialer circular group. In addition, you may configure PAP or CHAP
authentication.
After completing the basic DCC configurations, follow these steps to configure an
interface to receive calls from multiple remote ends:
Configuring multiple interfaces to place calls to one or multiple remote
ends
As shown in the following figure, multiple interfaces at the local end place calls to
one or multiple remote ends (the components in inverse color represent the
routers irrelevant to the networking):
