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
I. Configuring the link idle time
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 to the "permit" rule and needs to be transferred.
Perform the following configuration in dial interface (physical or dialer interface) view.
Table 1-30 Configure the link idle time
Configure the link idle time
Restore the link idle time to the default value
By default, the link idle time is 120 seconds.
Note:
Modified idle timer value does not take effect if the link has been set up. It takes effect
only when the link is set up again for the next call.
II. Configuring the link disconnection time before initiation of the next call
After a line for DCC calls enters the down status due to faults or disconnection, a
specified period of time must be elapsed (the interval before it can originate the next
call) before a new dialup connection can be established again. Thereby, the possibility
of overloading the remote PBX can be prevented.
Perform the following configuration in dial interface (physical or dialer interface) view.

initiating the next call
Restore the link disconnection time before initiating
the next call to the default value
