Definition
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.
Definition
Section Monitoring Background Block Errors (BBE-SM) indicates the
number of background block errors recorded in the OTN section during
the PM time interval.
Section Monitoring Errored Seconds (ES-SM) indicates the errored
seconds recorded in the OTN section during the PM time interval.
Section Monitoring Severely Errored Seconds (SES-SM) indicates the
severely errored seconds recorded in the OTN section during the PM time
interval.
Section Monitoring Unavailable Seconds (UAS-SM) indicates the
unavailable seconds recorded in the OTN section during the PM time
interval.
Section Monitoring Failure Counts (FC-SM) indicates the failure counts
recorded in the OTN section during the PM time interval.
Section Monitoring Errored Seconds Ratio (ESR-SM) indicates the
errored seconds ratio recorded in the OTN section during the PM time
interval.
Section Monitoring Severely Errored Seconds Ratio (SESR-SM)
indicates the severely errored seconds ratio recorded in the OTN section
during the PM time interval.
Section Monitoring Background Block Errors Ratio (BBER-SM)
indicates the background block errors ratio recorded in the OTN section
during the PM time interval.
Path Monitoring Background Block Errors (BBE-PM) indicates the
number of background block errors recorded in the OTN path during the
PM time interval.
Path Monitoring Errored Seconds (ES-PM) indicates the errored seconds
recorded in the OTN path during the PM time interval.
