D.5.2.5 Current Tab
The Current tab allows you to assign thresholds and alarm severities for the transponder laser current
levels.
D.5.2.6 Power Tab
The Power tab allows you to assign thresholds and alarm severities for the transponder Laser 1 power
levels.

Field Description
FEC Counters
Errored Seconds Sets the highthreshold forthe numberof FECerrored seconds (ES) and the alarm severity
level.
Severely Errored Seconds Setsthe high threshold forthe number of FEC severely erroredseconds (SES) and thealarm
severity level.
Background Block Errors Sets the high threshold for the number of FECbackground 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).
TableD-254 Field Descriptions for the Current Tab
Field Description
Value When theUpdate button is clicked, displays the current value of the laser current.
Degrade Sets the degrade threshold for the laser current (in mA) and the alarm severity level.
Fail Sets the failure threshold for the laser current (in mA) and the alarm severity level.
TableD-255 Field Descriptions for the Power Tab
Field Description
Value When the Update button is clicked, displays the current power of Laser 1.
Low Sets the low threshold for the laser power (in mW) and the alarm severity level.
High Sets the high threshold for the laser power (in mW) and the alarm severity level.
