DS1 > Line Thresholds
Use the Line Thresholds subtab to provision the DS-1 near and far end line thresholds.
 
Item
Description
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-min. threshold-crossing alerts (TCAs).
1 Day
Select to enter threshold information for a generation of 1-day TCAs.
Port
Displays the port number.
CV
(Near End only) Sets the threshold for the number of coding violations. Coding violations are bit interleaved parity (BIP) errors that are detected in the incoming signal. A threshold is associated with this parameter, and the table cell is flagged in red when it exceeds the threshold.
ES
(Near and Far End) 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
(Near End only) 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 and one or more incoming defects at that layer. The value of x depends on the line rate and bit error rate.
LOSS
(Near End only) Sets the threshold for the number of one-second intervals containing one or more loss of signal (LOS) defects.
Apply
Applies changes made to the fields in the tab.
Reset to Default
Resets the threshold values to the node default threshold values.
Reset
Cancels any changes to the tab and returns the fields to their last-saved settings.
Help
Displays context-sensitive help.
