Definition
Regenerator Section Errored Second (RS-ES) is a one-second period with
one or more errored blocks or at least one defect.
Regenerator Section Errored Second Ratio (RS-ESR) is the ratio of
errored seconds to total seconds in available time during a fixed
measurement interval.
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.
Regenerator Section Severely Errored Second Ratio (RS-SESR) is the
ratio of SES to total seconds in available time during a fixed measurement
interval.
Regenerator Section Background Block Error (RS-BBE) is an errored
block not occurring as part of an SES.
Regenerator Section Background Block Error Ratio (RS-BBER) is the
ratio of BBE to total blocks in available time during a fixed measurement
interval. The count of total blocks excludes all blocks during SESs.
