II. Configuring auto-dial
This function can only be used with C-DCC. With a C-DCC, after the router is started,
the DCC will automatically attempt to dial the remote end of the connection without
requiring a triggering packet. If a normal connection cannot be established with the
remote end, DCC will automatically retry at a certain interval. Compared with the
auto-dial DCC triggered by packets, such connections do not automatically disconnect
due to timeout. In other words, the dialer timer idle command does not take effect on
auto-dial.
Perform the following configuration in dial interface (physical or dialer interface) view.

By default, auto-dial is not configured. If auto-dial function is enabled, the interval for
auto-dial defaults to 300 seconds.
III. Configuring dialer number circular standby
This function can only be used with C-DCC. When setting the same destination
addresses using C-DCC, multiple dialer route commands can be configured, these
commands corresponding to different dialer numbers. These dialer route commands
form a kind of circular standby, i.e., which means that if the calling dial number can not
connect to peer end, then the number configured in next dialer route command will be
selected automatically for re-calling.
Perform the following configuration in dial interface (physical or dialer interface) view.

1.2.9 Configuring Attributes of DCC Dial Interface

C-DCC and RS-DCC also have some optional parameters. Flexibly configuring these
parameters can improve DCC efficiency, and hence satisfies various requirements.
