docsIf31CmtsCmUsOfdmaChannelThresholdRxMerValue

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.
