SONET Thresholds (Line, Section, and Path for OC-N, MRC-N, and EC1 Cards)
The SONET Thresholds subtab allows you to edit SONET thresholds for cards and ports. For a list of ONS nodes and cards that support this subtab, see Provisioning.
The thresholds shown depend on the direction (near or far end) and types (line, section, path) that you choose. Some thresholds do not apply, depending on the card.
Note
Thresholds do not appear until a circuit is created.
 
Port
Displays the port number.
CV
(Line, Section, Path) Sets the threshold for the number of coding violations. Coding violations are BIP errors that are detected in the incoming signal. The table cell is flagged in red when it exceeds the threshold.
ES
(Line, Section, Path) Sets the threshold for the number of errored seconds. An errored second is a one-second period with one or more coding violations at that layer or one or more incoming defects at that layer.
SES
(Line, Section, Path) Sets the threshold for the number of severely errored seconds. A severely errored second is a one-second period with x or more coding violations at that layer or one or more incoming defects at that layer. The value of x depends on the line rate and BER.
FC
(Line, Path) Sets the threshold for the failure count.
UAS
(Line, Path) Sets the threshold for the unavailable seconds.
PSC
(Line) Sets the threshold for the protection switching count.
PSD
(Line) Sets the threshold for the protection switching duration.
PSC-W
(Line) Sets the threshold for the working protection switching count. (PSC-W does not increment on OC-3 cards.)
PSD-W
(Line) Sets the threshold for the working protection switching duration. (PSD-W does not increment on OC-3 cards.)
PSC-S
(Line) Sets the threshold for the span protection switching count. (PSC-S does not increment on OC-3 cards.)
PSD-S
(Line) Sets the threshold for the span protection switching duration. (PSD-S does not increment on OC-3 cards.)
PSC-R
(Line) Sets the threshold for the ring protection switching count. (PSC-R does not increment on OC-3 cards.)
PSD-R
(Line) Sets the threshold for the ring protection switching duration. (PSD-R does not increment on OC-3 cards.)
SEFS
(Section) Sets the threshold for the severely errored framing seconds, which is a count of 1-second performance report message (PRM) intervals containing an SE=1.
PPJC-PDET
(Path) Sets the threshold for the positive pointer justification count, path detected.
NPJC-PDET
(Path) Sets the threshold for the negative pointer justification count, path detected.
PPJC-PGEN
(Path) Sets the threshold for the positive pointer justification count, path generated.
NPJC-PGEN
(Path) Sets the threshold for the negative pointer justification count, path generated.
PJCDIFF
(Path) Sets the threshold for the Pointer Justification Count Difference, which is the absolute value of the difference between the total number of detected pointer justification counts and the total number of generated pointer justification counts. That is, PJCDiff is equal to (PPJC-PGen – NPJC-PGen) – (PPJC-PDet – NPJC-PDet).
PJCS-PDET
(Path) Sets the threshold for the Pointer Justification Count Seconds - STS Path Detect (PJCS-PDet), which is a count of the one-second intervals containing one or more PPJC-PDet or NPJC-PDet.
PJCS-PGEN
(Path) Sets the threshold for the Pointer Justification Count Seconds - STS Path Generate (PJCS-PGen), which is a count of the one-second intervals containing one or more PPJC-PGen or NPJC-PGen.
Directions
Select Near End or Far End for the performance monitoring (PM) direction. To change the direction, choose the desired direction and click Refresh.
Intervals
Select 15 Min or 1 Day for the PM interval. To change the time interval, choose the desired interval and click Refresh.
Types
Select Line, Section, Path, STS, or VT where applicable. To change the type, choose the desired type and click Refresh.
Refresh
Refreshes the tab fields.
Reset to Default
Resets the values of all thresholds to the node default threshold values.
Apply
Applies changes made to the fields in the tab.
Reset
Cancels any changes to the tab and returns the fields to their last-saved settings.
Help
Displays context-sensitive help.
