15.6.2 STM-1E Card Performance Monitoring Parameters
Figure 15-8 shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the STM-1E card.

Ports 9-12 can be provisioned as E4 framed from the Provisioning > Ports tabs. Figure 15-9 shows the
VC4 performance monitoring parameters in E4 mode.
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.
