Definition
Regenerator Section Background Block Error (RS-BBE) is an errored block not
occurring as part of an SES.
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 Ratio (RS-SES) is the ratio of SES to
total seconds in available time during a fixed measurement interval.
Regenerator Section Background Block Error Ratio (RS-BBE) 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.
Regenerator Section Unavailable Second (RS-UAS) is a count of the seconds when
the regenerator section was unavailable. A section becomes unavailable when ten
consecutive seconds occur that qualify as RS-UASs, and it continues to be
unavailable until ten consecutive seconds occur that do not qualify as RS-UASs.
