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.

A count of received packets that contain non-errored data code groups that
have start and end delimiters.
A count of received packets that contain errored data code groups that
have start and end delimiters.
A count of received code groups that do not contain a start or end
delimiter.
A count of received packets containing idle ordered sets.
A count of received packets containing nonidle ordered sets.
A count of received data code groups that do not contain ordered sets.

Definition
Enterprise System Connection (ESCON), DV6000, SDI/D1 video, and high definition
television (HDTV) client signals are unframed payload data types. If the configured payload
data type is unframed, line threshold provisioning and performance monitoring are not
available.
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.
