Definition
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.
Multiplex Section Severely Errored Second ratio (MS-SESR) is the ratio
of SES to total seconds in available time during a fixed measurement
interval.
Multiplex Section Background Block Error (MS-BBE) is an errored block
not occurring as part of an SES.
Multiplex Section Background Block Error Ratio (MS-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.
Multiplex Section Unavailable Seconds (MS-UAS) is a count of the
seconds when the section was unavailable. A section becomes unavailable
when ten consecutive seconds occur that qualify as MS-SESs, and it
continues to be unavailable until ten consecutive seconds occur that do not
qualify as MS-SESs. When the condition is entered, MS-SESs decrement
and then count toward MS-UAS.
Multiplex Section Errored Block (MS-EB) indicates that one or more bits
are in error within a block.
