730CHAPTER 51: CONFIGURING DCC

Configuring the timeout of call setting up

When placing DCC calls to some remote ends, the intervals between originating the calls and establishing the connections are not the same. To effectively control the time that should wait for the connection after a call is originated, the user can configure the wait-carrier timer to specify a duration, after which DCC will terminate the call if the connection cannot be established.

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

Table 771 Configure the Timeout of Call Setting Up

Operation	Command
Configure the timeout of call setting up	dialer timer wait-carrier seconds
Restore the timeout of call setting up to	undo dialer wait-carrier
the default value

By default, the timeout of call setting up is 60 seconds.

Configuring the buffer queue length of the dialer

Before a dialer buffer queue is established, a packet received from the dial interface will be discarded if the connection is not established yet. However, if a buffer queue is established on the dial interface, the packet will be held until a connection is established rather than discarded.

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

Table 772 Configure the Buffer Queue Length of the Dial Interface

Operation	Command
Configure the buffer queue length of the	dialer queue-length packets

Remove the buffer queue length of the	undo dialer queue-length

By default, no buffer queues are configured on dial interfaces.
