Configuring advanced DCC functions

Configuring an ISDN leased line

An ISDN leased line can be configured with C-DCC but not RS-DCC. This function is fulfilled through
establishing semi-permanent ISDN MP connections. Such an application requires a leased line to be
established on the PBX of your telecom service provider and has been connected to the remote
device.
To configure an ISDN leased line:
Step
Enter system view.
1.
Enter physical interface
2.
view.
Specify a B channel for ISDN
3.
leased line connection.
ISDN BRI interfaces support both 64 kbps and 128 kbps leased lines. For more information, see
"Configuring ISDN."

Configuring auto-dial

Auto-dial can be used with C-DCC but not RS-DCC. With auto-dial enabled, DCC automatically dials
the remote end of connection upon each device startup without requiring a triggering packet. If the
connection cannot be established, it will retry at certain intervals. The established connection does
not disconnect due to timeout of the idle-timeout timer as it would in the traffic-triggered dial
approach. Its configuration thus voids the dialer timer idle command.
To configure auto-dial:
Step
Enter system view.
1.
Enter dialup interface
2.
(physical or dialer interface)

Configure one or multiple

destination addresses and
dial strings that can be
auto-dialed.
Set the auto-dial interval.
4.

Configuring circular dial string backup

In C-DCC, configure multiple dialer route commands for the dial strings used to call a destination
address. These dial strings are backups to each other. If DCC fails to call the remote end with a dial
string, it will select the dialer route command with the next dial string for another try.
