This is the overridden value of link delay (ms) that, if staged
successfully with the remote, is reported to the routing system for
metric calculations. A zero indicates that an override value has not
been provided and that only the measured value will be reported to
the routing system.
If this value is changed on a Trunk or DpnGateway that is enabled,
the LOCK and UNLOCK commands must be issued to the
component to restage the override with the remote.
