 SEF = Severely Errored Frame (SEF) defects.
 FEC = Forward error correction (FEC).
 CRC = Cyclic Redundancy Check
 NCD = NCD (no cell delineation)
 HEC = Header Error Control (HEC) violations.
 OCD = The number of Out of Cell Delineation events since the last reset. An
    OCD event is declared when seven consecutive ATM cells have Header Error
     Control (HEC) violations.
