This object contains the maximum one-way availability flr in the forward
direction, from among the set of availability flr values calculated by
the MEP in this Measurement Interval. There is one availability flr
value for each 'delta_t' time period within the Measurement Interval, as
specified in MEF 10.2.1.
The flr value is a ratio that is expressed as a
percent with a value of 0 (ratio 0.00) through 100000 (ratio 1.00).
Units are in milli-percent, where 1 indicates 0.001 percent.
