Field |
| Description |
|
| |
Background Block Errors | Sets the high threshold for the number of FEC 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. |
|
| |
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 |
|
| |
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 | Sets the high threshold for the uncorrected codeword rate (UCR) and the alarm severity level. | |
Rate |
| 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.5.7.5 Current Tab
The Current tab allows you to assign thresholds and alarm severities for the transponder laser current levels.
Table
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. |
|
|
D.5.7.6 Power Tab
The Power tab allows you to assign thresholds and alarm severities for the transponder laser power levels.
Table
Field
Description
Laser 1
Value | When the Update button is clicked, displays the current power of Laser 1 (in mW). |
|
|
Low | Sets the low threshold for the Laser 1 power, in mW, and the alarm severity level. |
|
|
High | Sets the high threshold for the Laser 1 power, in mW, and the alarm severity level. |
|
|
D.5.7.7 Input Power Tab
The Input Power tab allows you to assign thresholds and alarm severities for the power coming into the transponder lasers.
