Packets that do not match any permit statements or that match a deny statement. When receiving
such a packet, DCC either sends it out without resetting the idle-timeout timer if a link is present, or
drops it without originating calls for link setup if no link is present.
For DCC to send packets normally, you must configure a dial ACL and associate it with the concerned
dialup interface (dialer interface) by using the
dialer-group
command.
If no dial ACL is configured for the dialer access group associated with a dialup interface, DCC drops
received packets on the interface as uninteresting ones.

Dialer interface number, in the range of 0 to 16.
Description
Use
interface dialer
to create a dialer interface. In C-DCC, this equals creating a dialer circular group.
Use
undo interface dialer
to remove a dialer interface.
By default, no dialer interface is created.
The dialer interface has a fixed baudrate of 64000 bps.
In C-DCC, you may assign multiple physical interfaces to a dialer interface to inherit the attributes of this
dialer interface by assigning them to the dialer circular group for the dialer interface with the
dialer
circular-group
command. This is efficient where calling multiple destinations simultaneously is desired,
because instead of configuring individual physical interfaces, you only must configure multiple dialer
routes on the dialer interface.
In RS-DCC, any dialer interface can use the services provided by multiple physical interfaces, and
individual physical interfaces can provide services for multiple dialer interfaces at the same time.
Therefore, authentication must be configured on these physical interfaces, so as to use the username of
a dial-in party to locate the corresponding dialer interface for the call. In this mode, physical interfaces
and dialer interfaces are dynamically bound. Furthermore, a dialer interface can only call a destination
address as specified in the
dialer number
command.
