Dcc Configuration - 3Com MSR 50 Series Configuration Manual

After completing C-DCC configurations, follow these steps to configure ISDN
leased line:
To do... Use the command...
Enter system view system-view
Enter physical interface interface interface-type
view interface-number
Specify a B channel for dialer isdn-leased number
ISDN leased line
connection
ISDN BRI interfaces support both 64 kbps and 128 kbps leased lines. For more
information, refer to "Configuring ISDN BRI" on page
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 connection thus established 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.
Follow these steps to configure auto-dial:
To do...
Enter system view
Enter dial interface (physical
or dialer) view
Configure one or multiple
destination addresses and dial
strings that can be
auto-dialed
Set the auto-dial interval
Configuring circular dial string backup
In C-DCC, you may 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.
Follow these steps to configure dial string circular backup:
To do...
Enter system view
Enter dial interface (physical
or dialer) view
