An unlocked demodulator will activate downstream path failure and path warning
alarms.
ESR Threshold Exceeded
G.826 ESR threshold exceeded. This is a path warning alarm.
Probable Cause
Path conditions, interference, or equipment malfunction.
Recommended Actions
• Check for other alarms, particularly those that indicate a total LOS due to a
component failure, or a complete path failure:
- Component failure or Rx path failure alarms must be checked before
investigating an RSL Below Threshold alarm.
- If the only other alarms are Demodulator Not Locked, and its downstream path
failure and path warning alarms, a path failure is indicated, which may be caused
by a complete path fade or a remote Tx failure.
- If ESR Threshold Exceeded is the only alarm, or the only other alarms
are also
path warning alarms , check G.826 and RSL measurements at both ends using
the Portal Performance screen:
- If low RSL and G.826 alarms are present
at both ends of the link , a path
problem is indicated, which most likely will be caused by a degraded path due to
rain, diffraction or multipath fading. Check recommended actions for BER
alarms.
- If an ESR alarm is present
at just the local end and RSL is normal , interference
from another link should be suspected. Use the Portal History and Event
Browser screens to track the onset of ESR alarms, which for a newly installed
interfering link should show a repetition of G.826 alarm occurrences as the new
link is installed and commissioned.
Additional Information
An ES (errored second) is a one-second period with one or more errored blocks or at
least one defect.
ESR (errored second ratio) is the ratio of ES to total seconds in available time during
a fixed measurement interval. For Eclipse the measurement interval is 60 seconds,
and the ESR alarm threshold is set at 20%.
FPGA Software Load Failure
The software loading of the Field Programmable Gate Array has failed. This is a
critical alarm.
Probable Cause
Equipment or process malfunction.
Recommended Actions
1. If the alarm is raised on initial power-on, retry (reboot) the terminal by switching
the 48 Vdc power off, pausing, and then powering on.
2. If the alarm is raised after a new SW load, reload the previous SW version and
re-check the alarm. If cleared, retry the SW load.
3. If the alarm is raised after a capacity reconfiguration, revert to the previous
