The amount of time (in 100ms increments) over which the
threshold is defined. The default value is 10 (1 second).
If cdot3OamErrFrameThreshold frame errors occur within a window
of cdot3OamErrFrameWindow seconds (measured in tenths of
seconds), an Event Notification OAMPDU should be generated
with an Errored Frame Event TLV indicating the threshold has
been crossed in this window.
