SONET Thresholds (Line, Section, and Path for OC-N and EC1 Cards)


The table below provides SONET thresholds for the following cards/ports:

The thresholds shown depend on the direction (near or far end) and types (line, section, path) that you choose. Thresholds do not appear until a circuit is created.

Port

The port number.

CV

(Line, Section, Path) The number of coding violations. Coding violations are bit interleaved parity errors that are detected in the incoming signal. A threshold is associated with this parameter, and the table cell will be flagged in red when it exceeds the threshold. You can set thresholds using the CLI.

ES

(Line, Section, Path) 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) The number of severely errored seconds. A severely errored second is a one-second period with x or more coding violations at that layer one or more incoming defects at that layer. The value of x depends on the line rate and bit error rate.

FC

(Line, Path) Displays the failure count.

UAS

(Line, Path) Displays the unavailable seconds.

PSC

(Line) Displays the protection switching count.

PSD

(Line) Displays the protection switching duration.

PSC-W

(Line) Displays the working protection switching count. (PSC-W does not increment on OC-3 cards.)

PSD-W

(Line) Displays the working protection switching duration. (PSD-W does not increment on OC-3 cards.)

PSC-S

(Line) Displays the span protection switching count. (PSC-S does not increment on OC-3 cards.)

PSD-S

(Line) Displays the span protection switching duration. (PSD-S does not increment on OC-3 cards.)

PSC-R

(Line) Displays the ring working protection switching count. (PSC-R does not increment on OC-3 cards.)

PSD-R

(Line) Displays the ring working protection switching duration. (PSD-R does not increment on OC-3 cards.)

SEFS

(Section) Displays the severely errored framing seconds, which is a count of 1-second performance report message (PRM) intervals containing an SE=1.

PPJC-PDET

(Path) Displays the positive pointer justification count, path detected.

NPJC-PDET

(Path) Displays the negative pointer justification count, path detected.

PPJC-PGEN

(Path) Displays the positive pointer justification count, path generated.

NPJC-PGEN

(Path) Displays the negative pointer justification count, path generated.

PJCDIFF

(Path) Pointer Justification Count Difference 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) Pointer Justification Count Seconds, STS Path Detect (PJCS-PDet) is a count of the one-second intervals containing one or more PPJC-PDet or NPJC-PDet.

PJCS-PGEN

(Path) Pointer Justification Count Seconds - STS Path Generate (PJCS-PGen) is a count of the one-second intervals containing one or more PPJC-PGen or NPJC-PGen.
