This attribute indicates the number of seconds during which the
PLCP far end is unavailable. The PLCP Path Layer becomes
unavailable at the declaration of PLCP RAI (Remote Alarm
Indication). Service becomes available again after this condition is
cleared. For second intervals where PLCP FEUAS are counted,
counting of PLCP Far-End Coding Violations (FECV), PLCP Far-
End Errored Seconds (FEES), and PLCP Far-End Severely Errored
Seconds (FESES) is inhibited.
