Regenerator Section Errored Block (RS-EB) indicates that one or more
bits are in error within a block.
Regenerator Section Background Block Error (RS-BBE) is an errored
block not occurring as part of an SES.
Regenerator Section Errored Second (RS-ES) is a one-second period with
one or more errored blocks or at least one defect.
Regenerator Section Severely Errored Second (RS-SES) is a one-second
period which contains 30 percent or more errored blocks or at least one
defect. SES is a subset of ES.
