Line Thresholds (OC3, OC12, OC48, OC192, OC768)
Use the Line Thresholds subtab to provision the thresholds for the TXP or MXP cards provisioned for OC-N (SONET) payloads. The thresholds that appear depend on whether you choose near or far end, line or section thresholds.
 
Item
Description
Port
Displays the port number.
CV
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 will be flagged in red when it exceeds the threshold. You can set thresholds using the command-line interface (CLI).
ES
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
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 bit error rate.
SEFS
Sets the threshold for the severely errored framing seconds.
FC
Sets the threshold for the failure count.
UAS
Sets the threshold for the unavailable seconds.
Directions
Select near end or far end for the PM direction.
Intervals
Select 15 Min or 1 Day for the PM interval.
Types
Select Line, Section, or Path, where applicable. Some screens have the option to choose from Line, Section, or VT.
Refresh
Refreshes the tab fields.
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.
