SDH Performance Monitoring for Optical Cards
8.6.2 STM-4 Card Performance Monitoring Parameters
Figure 8-20 shows the signal types that support near-end and far-end PMs. Figure 8-21 shows where
overhead bytes detected on the ASICs produce performance monitoring parameters for the STM-4 card.

Note PMs on the protect VC4 are not supported for MS-SPRing.
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 Background Block Errors (BBE) to total blocks in available time during
a fixed measurement interval. The count of total blocks excludes all
blocks during SESs.
