15.6.5 TXP_MR_10G Card Performance Monitoring Parameters
shows the signal types that support near-end and far-end PM parameters.
shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the TXP_MR_10G card.

HP-ES
High-Order Path Errored Second (HP-ES) is a one-second period with one
or more errored blocks or at least one defect.
HP-SES
High-Order Path Severely Errored Seconds (HP-SES) is a one-second
period containing 30 percent or more errored blocks or at least one defect.
SES is a subset of ES.
HP-UAS
High-Order Path Unavailable Seconds (HP-UAS) is a count of the seconds
when the VC path was unavailable. A low-order path becomes unavailable
when ten consecutive seconds occur that qualify as HP-SESs, and it
continues to be unavailable until ten consecutive seconds occur that do not
qualify as HP-SESs.
HP-BBE
High-Order Path Background Block Error (HP-BBE) is an errored block
not occurring as part of an SES.
HP-ESR
High-Order Path Errored Second Ratio (HP-ESR) is the ratio of errored
seconds to total seconds in available time during a fixed measurement
interval.
HP-SESR
High-Order Path Severely Errored Second Ratio (HP-SESR) is the ratio
of SES to total seconds in available time during a fixed measurement
interval.
HP-BBER
High-Order Path Background Block Error Ratio (HP-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.
