Configuring Circular DCC
If Circular DCC is used, each physical interface can either be directly configured
with the DCC parameters, or bound to a dialer interface to inherit the DCC
parameters through a dialer circular group. Between these two options,
configuring the DCC parameters directly on a physical interface is only applicable
for a single interface to originate calls to one or more remote ends. However,
dialer circular group is also applicable for multiple interfaces to originate calls to
one or more remote ends in addition to that.

Dialer circular group associates a dialer interface with a group of physical
interfaces. The DCC configurations of this dialer interface are automatically
inherited by all the physical interfaces in the dialer circular group. After
configuring the parameters for the dialer circular group, any physical interface in
the group can call any predefined destination if the dialer interface is associated
with multiple destinations.

Depending on the network topology and DCC dialing demands, such as one
interface or multiple interfaces can both originate and receive calls, the user can
flexibly use one configuration or the combination of several configurations in the
Circular DCC configurations introduced below.

In the Circular DCC implementation of DCC, the two dial parties can configure PAP
(Password Authentication Protocol) or CHAP (Challenge-Handshake
Authentication Protocol) authentication. However, the other party must configure
authentication if one party has done that. For security of dialing ID, the user is
recommended to configure authentication in actual networking applications. For
