dialer enable-circular
Syntax dialer enable-circular
undo dialer enable-circular
View Dial interface (physical or dialer) view
Parameter None
Description Use the
dialer enable-circular command to enable circular dial control center
(C-DCC).
Use the
undo dialer enable-circular command to disable C-DCC.
By default, C-DCC is enabled on ISDN BRI and PRI interfaces but disabled on other
interfaces.
You need to enable C-DCC before you can use it.
To use resource-shared DCC (RS-DCC) on a dialer interface, you need to configure
the dialer user command and the dialer bundle command on the dialer
interface and assign physical interfaces to the dialer bundle with the dialer
bundle-member command.
After you disable C-DCC, the system clears all configurations on dial interfaces. To
make them recover, you need to shut down and then bring up them by
performing the shutdown command and then the undo shutdown command.
