This attribute indicates the total number of Far-End Errored
Seconds (FEES). A FEES is declared for second intervals
containing with one or more Far-End Coding Violations (FECV) or
one or more Far-End Receive Failure (FERF) defects. A FERF
defect occurs when the FERF bit in the received frame is set to one.
For second intervals where Far End Unavailable Seconds (FEUAS)
are counted, counting of FEESs is inhibited.
