This notification indicates that the G.Bond port's upstream
data rate has reached/dropped below or exceeded the low
upstream rate threshold, specified by
gBondPortConfThreshLowUpRate.
          
This notification MAY be sent for the -O subtype ports
while the port is 'up', on the crossing event in both
directions: from normal (rate is above the threshold) to low
(rate equals the threshold or is below it) and from low to
normal.  This notification is not applicable to the -R
subtypes.
          
It is RECOMMENDED that a small debouncing period of 2.5 sec,
between the detection of the condition and notification,
be implemented to prevent simultaneous LinkUp/LinkDown and
gBondLowUpRateCrossing notifications from being sent.
          
The adaptive nature of the G.Bond technology allows the port
to adapt itself to the changes in the copper environment;
e.g., an impulse noise, alien crosstalk, or a
micro-interruption may temporarily drop one or more BCEs in
the aggregation group, causing a rate degradation of the
aggregated G.Bond link.  The dropped BCEs would then try to
re-initialize, possibly at a lower rate than before, adjusting
the rate to provide the required target SNR margin.
          
Generation of this notification is controlled by the
gBondPortConfLowRateCrossingEnable object.
          
This object maps to the TR-159 notification
nGroupLowUpRateCrossing.

This notification indicates that the G.Bond port's downstream
data rate has reached/dropped below or exceeded the low
