Line Thresholds (OC3, OC12, OC48, OC192)


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.

Port

The port number.

CV

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

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

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.

SEFS

The severely errored framing seconds.

FC

The failure count.

UAS

The unavailable seconds.
