This read-write TruthValue specifies, network-wide, whether the Deroute Delay feature is enabled; the feature is enabled if the value is True. An administrator uses this network-wide switch, alongside parOnOffDrtDelay, to control whether trunks and connections are held up briefly on failure rather than derouted instantly, allowing transient faults to clear without disruption. For example, enabling deroute delay network-wide means a brief trunk blip anywhere in the network won't immediately trigger a wave of connection rerouting.
