This attribute indicates the total number of Far-End Path Severely
Errored Seconds (FEPSESs) that have been counted. A FEPSES is
declared for second intervals containing more than x FEPCVs or
one or more P-RDI defects. The value of x is 2400 for a 155 Mbits/
sec interface. Counting of FEPSESs is inhibited when FEPUAS is
counted over the monitored second.
