Intervals are 15 minute periods, if the CSU has not been reset or power cycled
in the previous 24 hours there should be 96 intervals (24 hours @ 4 15 minute
intervals each).Key to abbreviations:
ES = Errored Second, any second during which one or more bit errors have been detected
UAS = Unavailable Second, any second during which an Unavailable Signal State occurs. This occurs after ten consecutive SES and clears only after ten consecutive nonSES.
BES = Bursty Errored Seconds, a second having between 2 and 319 CRC-6 error events. Bursty errored seconds are not counted when an SES or UAS is counted.
SES = Severely Errored second, a second with 320 or more CRC-6 error events, or one or more OOF (Out Of Frame) events.
LOFC = Loss Of Frame Count, an accumulated value equal to the number of times that a Loss Of Frame has been declared. Loss of frame is declared when either LOS (Loss Of Signal) or OOF (Out Of Frame) is true for two to three seconds. LOF is cleared only after 10 seconds with LOS and OOF not true.
