Acronym Meaning
ES Errored Second — any second during which one or more bit
errors have been detected.
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.
UAS Unavailable Second — any second during which an
Unavailable Signal State occurs.
An Unavailable Signal State condition is declared after ten
consecutive SES and clears only after ten consecutive seconds
which are not Severely Errored Seconds.
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 clear.
