A count of E3 frames containing a Far-End Block Error (FEBE). A FEBE is reported over the FEBE bit each time the far-end terminal detects a BIP-8 error in a received E3 frame. For second intervals where Far End Unavailable Seconds (FEUAS) or Far End Severely Errored Seconds (FESES) are counted, counting of FECVs is inhibited. This attribute is a non-negative integer which monotonically increases until it reaches a maximum value, at which point it wraps around and starts increasing again from zero.
