DS1 > Elect Path Thresholds


Use the Electrical Path Thresholds subtab to view and provision electrical path thresholds.

Near End

Select Near End to display the near-end thresholds.

Far End

Select Far End to display the far-end thresholds.

15 Min

Select to enter threshold information for a generation of 15-minute TCAs.

1 Day

Select to enter threshold information for a generation of 1-day TCAs.

Shows selected thresholds.

Port

The port number.

CV

(Near End and Far End) 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 CTC.

ES

(Near End and Far End) 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

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

AISS

(Near End only) The alarm indication signal seconds thresholds for the path.

UAS

(Near End and Far End) The unavailable seconds.

CSS

(Far End only) The count of seconds during which a controlled slip has occurred. Counts of controlled slips can be accurately made only in the path terminating NE of the DS1 signal where the controlled slip takes place.

ESA

(Far End only) The Errored Seconds-A, which is a count of 1 second intervals with exactly one CRC-6 error and no AIS or SEF.

ESB

(Far End only) The Errored Seconds-B, which is a count of 1 second intervals with exactly one CRC-6 error and no AIS or SEF.

SEFS

(Far End only) The severely errored framing seconds, which is a count of 1-second performance report message (PRM) intervals containing an SE=1.
