ONFIGURATION

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.

This function can only be used with Circular DCC. When setting the same 
destination addresses using Circular DCC, multiple 

 commands can 

be configured, these commands corresponding to different dialer numbers. These 

 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 

 command will be selected automatically for re-calling. 

Perform the following configuration in dial interface (physical or dialer interface) 
view.

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

DCC dial interface attributes configuration overs the process to:

■

Configure the link idle time

■

Configure the link disconnection time before initiating the next call

■

Configure the link idle time when interface completion

■

Configure the timeout of call setting up

■

Configure the buffer queue length of the dial interface

In the case that a dial interface originates a call, if the line is idle for an amount of 
time, DCC will disconnect the line. The idle time means that in the duration of it 
no packet in the ACL conforms the “permit” rule and needs to be transferred.
