This read-write INTEGER sets the value of the deroute delay timer, in seconds, for the trunk. An administrator uses this timer to avoid immediately derouting connections the moment a trunk shows trouble, giving brief transient faults a chance to clear before triggering a disruptive reroute. For example, setting parTrkCnfgDerouteDelay to 30 seconds means a trunk that flickers into alarm for only a few seconds won't cause all its connections to be torn down and rerouted.
