Configuring DCC overlap receiving
By default, DCC operates in non-overlap receiving mode. A DCC called party starts establishing a
DCC connection as soon as the first digit of the called number is received, instead of waiting for the
complete called number to be gathered. With overlap receiving enabled, a DCC called party will not
start establishing a DCC connection until the complete called number is received.
Configure the overlap receiving mode only when DCC is configured on the current ISDN physical
interface.
Generally, you do not need to configure this feature. In the North American market, however, you
might need to configure this feature for interoperability purposes.

Configuring DCC timers and buffer queue length
C-DCC and RS-DCC are available with some optional parameters. Configure them appropriately to
improve on-demand dial efficiency.
DCC timers and buffer queue length
You can configure the following parameters on a dialup interface:
• Link idle-timeout timer—A link idle-timeout timer starts upon setup of a link. When the timer
expires, DCC disconnects the link.
• Holddown timer—A holddown timer starts upon disconnection of a link. The call attempt to
bring up this link can be made only after the timer expires, preventing a remote PBX from being
overloaded.
• Compete-idle timer—If all the channels are unavailable when DCC originates a new call,
contention occurs.
An idle-timeout timer starts upon setup of a link. If a call to another destination address is placed
at the same time, contention occurs. DCC starts a compete-idle timer to replace the idle-timeout
