Line Errored Seconds (ES-L) is a count of the seconds
containing one or more anomalies (BPV + EXZ) and/or defects
(that is, loss of signal) on the line.

ES-L
Section Errored Seconds (ES-S) is a count of the number of
seconds when at least one section-layer BIP error was detected
or an SEF or loss of signal (LOS) defect was present.
seconds when at least one section-layer BIP error was detected
or an SEF or loss of signal (LOS) defect was present.
ES-S
Line Failure Count (FC-L) is a count of the number of near-end
line failure events. A failure event begins when an Alarm
Indication Signal Line (AIS-L) failure is declared or when a
lower-layer, traffic-related, near-end failure is declared. This
failure event ends when the failure is cleared. A failure event
that begins in one period and ends in another period is counted
only in the period where it begins.

FC-L
Severely Errored Framing Seconds (SEFS-S) is a count of the
seconds when an SEF defect was present. An SEF defect is
expected to be present during most seconds when an LOS or
loss of frame (LOF) defect is present. However, there can be
situations when the SEFS-S parameter is only incremented
based on the presence of the SEF defect.

SEF-S
Line Severely Errored Seconds (SES-L) is a count of the
seconds containing more than a particular quantity of anomalies
(BPV + EXZ > 44) and/or defects on the line

SES-L
Section Severely Errored Seconds (SES-S) is a count of the
seconds when K (see Telcordia GR-253 for value) or more
section-layer BIP errors were detected or an SEF or LOS defect
was present.

SES-S
Line Unavailable Seconds (UAS-L) is a count of the seconds
when the line is unavailable. A line becomes unavailable when
ten consecutive seconds occur that qualify as SES-Ls, and it
continues to be unavailable until ten consecutive seconds occur
that do not qualify as SES-Ls.

SDH PM Parameter Definitions
The definitions for each type of SDH PM parameter available on an ONS 15454 ETSI node are shown in the following table. These
parameters become available when the client type is set to STM-1, STM-4, or STM-16 on a TXP_MR_2.5G or TXPP_MR_2.5G
card, STM-64 on a TXP_MR_10G, TXP_MR_10E, TXP_MR_10E_C, TXP_MR_10E_L, or ADM-10G, or WSE, or 10x10G-LC
