Definition
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.
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.
