This attribute is the RxMER value corresponding to the specified docsIf31CmtsCmUsOfdmaChannelRxMerThreshold percentile value. The CCAP sorts the subcarriers in ascending order of RxMER, resulting in a post-sorting subcarrier index ranging from 1 to the number of active subcarriers. If the percentile value corresponds to a non- integer post-sorting subcarrier index, the post-sorting index is truncated (floor function is applied); that is, the post-sorting index is selected which is the greatest integer less than or equal to the corresponding percentile value. For example, if there are 3677 active subcarriers and the 2nd percentile is specified, the CCAP computes floor(3677*0.02) = 73. That is, the RxMER value of the 73rd subcarrier in the sorted list is associated with the 2nd percentile. This is displayed in hundredth of a dB, but is only accurate to a quarter dB.
