Maximum link idle time
After the maximum link idle time is set, DCC disconnects calls on dialup interfaces
automatically if the link idle timer expires. Link idle time is the period in which no packet
is permitted by the dialer access control list (ACL) on the link.
Link disconnection time before a new call is initiated
If a CCC line is disconnected due to a fault or hang-up, the link is re-established only after
a certain period of time. This prevents PBX overload.
Link idle cut during interface competition
When a DCC is initiated, competition occurs if all channels are occupied. The idle timer
takes effect for a newly established link. If a call to another destination needs to be
established, a competition occurs. The system replaces the idle timer with the compete-idle
timer to control the ongoing call. When the idle time of the ongoing call reaches the
compete-idle timer, the call is disconnected.
Call setup timeout
Call setup time may vary with the remote end type. Configure the wait-carrier timer to
control the call setup time. If a call is not established within the wait-carrier time, DCC
terminates the call.
Buffer queue length on a dialup interface
If a dialup interface receives a packet but the call connection is not established, the dialup
interface discards the packet. However, if a buffer queue is configured on the dialup
interface, the dialup interface stores the packet in the buffer, and sends the packet after the
call connection is established.
