gInpLeftrThreshold - The upstream rate Threshold below which the Low Error Free Rate (LEFTR) defect is declared. The threshold used to declare leftr defects is expressed in fraction of the net data rate (NDR). The value 0 is a special value to indicate that the receiver shall use a special value for declaring leftr defect. The minimum valid threshold to declare leftr is ETR/2. The receiver shall ignore threshold values that are less than the minimum and shall use ETR/2 for declaring leftr defect instead. The valid values are all multiples of 0.01 from 0.01 to 0.99. This field uses 1 to equal 0.01 and 99 to equal 0.99.
