Table 15-45 Near-End or Far-End Regenerator Section PM Parameters for TXP_MR_10G Cards
Parameter Definition
RS-ES Regenerator Section Errored Second (RS-ES) is a one-second period with
one or more errored blocks or at least one defect.
RS-ESR Regenerator Section Errored Second Ratio (RS-ESR) is the ratio of
errored seconds to total seconds in available time during a fixed
measurement interval.
RS-SES 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.
RS-SESR Regenerator Section Severely Errored Second Ratio (RS-SES) is the ratio
of SES to total seconds in available time during a fixed measurement
interval.
RS-BBE Regenerator Section Background Block Error (RS-BBE) is an errored
block not occurring as part of an SES.
RS-BBER 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.
RS-UAS 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.
RS-EB Regenerator Section Errored Block (RS-EB) indicates that one or more
bits are in error within a block.

Parameter Definition
MS-ES Multiplex Section Errored Second (MS-ES) is a one-second period with
one or more errored blocks or at least one defect.
MS-ESR Multiplex Section Errored Second Ratio (MS-ESR) is the ratio of errored
seconds to total seconds in available time during a fixed measurement
interval.
