Table 15-57 Near-End or Far-End Regenerator Section PM Parameters for MXP_2.5G_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.

MXP_2.5G_10G Cards

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.

MS-SES

Multiplex Section Severely Errored Second (MS-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. For more information, see ITU-T G.829
Section 5.1.3.

MS-SESR

Multiplex Section Severely Errored Second ratio (MS-SESR) is the ratio
of SES to total seconds in available time during a fixed measurement
interval.

MS-BBE

Multiplex Section Background Block Error (MS-BBE) is an errored block
not occurring as part of an SES.
