Definition
Regenerator Section Errored Block (RS-EB) indicates that one or more
bits are in error within a block.
Regenerator Section Background Block Error (RS-BBE) is an errored
block not occurring as part of an SES.
Regenerator Section Errored Second (RS-ES) is a one-second period with
one or more errored blocks or at least one defect.
Regenerator Section Severely Errored Second (RS-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.

Multiplex Section Errored Block (MS-EB) indicates that one or more bits
are in error within a block.
Multiplex Section Background Block Error (MS-BBE) is an errored block
not occurring as part of an SES.
Multiplex Section Errored Second (MS-ES) is a one-second period with
one or more errored blocks or at least one defect.
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 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.

In CTC, the count fields for HP-PPJC and HP-NPJC PM parameters appear white and blank
unless they are enabled on the Provisioning > Line tabs. See the

High-Order Path Positive Pointer Justification Count, Path Detected
(HP-PPJC-Pdet) is a count of the positive pointer justifications detected
on a particular path on an incoming SDH signal.
