Field	Description
Background Block Errors	Sets the high threshold for the number of B1 background block errors (BBE) and the alarm
	severity level. An errored block is a block in which one or more bits are in error. A background
	block error is an errored block that does not occur as part of a severely errored second.
Bit Error Rate	Sets the high threshold for the B1 bit error rate and the alarm severity level. The BER is the
	ratio of received bits that contain errors.
Unavailable Seconds	Sets the high threshold for the number of B1 unavailable seconds (UAS) and the alarm severity
	level. The detection of 10 consecutive SES begins a period of UAS. The 10 SES detected are
	part of the UAS. The ES and SES counters decrement by 10 seconds and the UAS counter
	increments by an equivalent number of seconds. A new period of available time begins at the
	onset of 10 consecutive non-SES events.
FEC Counters
Errored Seconds	Sets the high threshold for the number of FEC errored seconds (ES) and the alarm severity
	level.
Severely Errored Seconds	Sets the high threshold for the number of FEC severely errored seconds (SES) and the alarm
	severity level.
Background Block Errors	Sets the high threshold for the number of FEC background block errors (BBE) and the alarm
	severity level.
Unavailable Seconds	Sets the high threshold for the number of FEC unavailable seconds (UAS) and the alarm
	severity level. The detection of 10 consecutive SES begins a period of UAS. The 10 SES
	detected are part of the UAS. The ES and SES counters decrement by 10 seconds and the UAS
	counter increments by an equivalent number of seconds. A new period of available time begins
	at the onset of 10 consecutive non-SES events.
Error Corrected Rate	Sets the high threshold for the bit error corrected rate (ECR) and the alarm severity level. The
	ECR is the ratio of FEC bit errors corrected to bits transmitted.
Uncorrected Codewords Rate	Sets the high threshold for the uncorrected codeword rate (UCR) and the alarm severity level.
	The UCR is the ratio of uncorrected codewords to codewords transmitted. A codeword is a
	block of N symbols that carry K information symbols and R redundant symbols (N = K+R).

D.5.8.4 Current Tab

The Current tab allows you to assign thresholds and alarm severities for the transponder laser current levels.

Field

Description

Laser 1

Value	When the Update button is clicked, displays the current value of the Laser 1 current (in mA).
Degrade	Sets the degrade threshold for the Laser 1 current, in mA, and the alarm severity level.
Fail	Sets the failure threshold for the Laser 1 current, in mA, and the alarm severity level.
