■ PERFORMANCE-Set-PM Threshold-Line (TL1 = SET-TH): This input
provisions values for the threshold crossing alert parameters applied to the
B2 line data collected for each OC-48, OC-12 and OC-3 line.
— The TCA Autonomous Report parameter specifies whether
autonomous reporting of threshold crossing alerts (TCAs) via TBOS
and TL1 is "Enable" or "Disable" for the selected
performance-monitoring bin and OC-48, OC-12 or OC-3 line(s).
— The Line Coding Violations parameter specifies the number of line
composite B2 coding violations that will cause a threshold crossing
alert for the selected performance-monitoring bin and OC-48, OC-12
or OC-3 line(s). This parameter is the base 10 logarithm of the
desired error rate. The values are integers from -11 to -7 (inclusive)
for the quarter-hour bin and integers from -12 to -7 (inclusive) for the
day bin.
— The Line Errored Seconds parameter specifies the number of line
errored seconds that will cause a threshold crossing alert for the
selected performance-monitoring bin and OC-48, OC-12 or OC-3
line(s). A line errored second is recorded for each second during
which there are one or more composite B2 coding violations, or a
line AIS defect is detected. This parameter is an integer from 1 to
900 (inclusive) for the quarter-hour bin and an integer from 1 to
65,535 (inclusive) for the day bin.
— The Line Severely Errored Seconds parameter specifies the number
of line severely errored seconds that will cause a threshold crossing
alert for the selected performance-monitoring bin and OC-48, OC-12
or OC-3 line(s). A line severely errored second is recorded for each
second during which there are 494 or more composite B2 coding
violations, or a line AIS defect is detected. For intervals with 10 or
more contiguous severely errored seconds, the severely errored
seconds will be recorded as unavailable seconds, not as severely
errored seconds. This parameter is an integer from 1 to 63
(inclusive) for the quarter-hour bin and an integer from 1 to 4095
(inclusive) for the day bin.
— The Line Unavailable Seconds parameter specifies the number of
line unavailable seconds that will cause a threshold crossing alert
for the selected performance-monitoring bin and OC-48, OC-12 or
OC-3 line(s). A line unavailable second is recorded after 10
consecutive line severely errored seconds. These 10 seconds are
counted, and each subsequent second is counted until there are 10
consecutive seconds without a line severely errored second. The 10
consecutive seconds without a line severely errored second are not
counted as unavailable seconds. This parameter is an integer from
1 to 63 (inclusive) for the quarter-hour bin and an integer from 1 to
4095 (inclusive) for the day bin.
■ PERFORMANCE-Set-PM Threshold-Optics (TL1 = SET-TH): This
input provisions values for the threshold crossing alert parameters applied
to the optical health data collected for each OC-48, OC-12 or OC-3 line.
