Eclipse Edge User Manual
More detailed Eclipse site-specific diagnostic data is enabled by opening, from
ProVision, a Portal session to an Eclipse terminal. Within Portal, a NOC operator has
access to all Portal screens, as if on-site.
Only where it is not possible to see a network beyond a full break, and therefore not
possible to see the far end of a link, does it become less certain as to which site carries
the faulty equipment, or if it is an equipment fault as distinct from a full path fade.
However, by looking at the Portal Alarm, Events Browser and History screens, you
can narrow down the options. For information on the use of these screens and other
Eclipse diagnostics screens, refer to:
•
Using Portal Diagnostics Screens for Edge on page 24
• ProVision User Guide
Before Going to Site Edge Checklist
Where possible, before going to site obtain the following information:
• Does the fault require immediate attention?
• Determine who is the best-placed person to attend the fault.
• Confirm the nature and severity of the reported fault, its location, Eclipse type,
frequency band, high/low end ODU, capacity, modulation and configuration
(non-protected, protected, diversity, ring). Ask:
• Is just one Eclipse link affected, or a number of links in the same geographical
area?
• Is the path down completely or is traffic passing but with a BER alarm?
• Is only one or a number of tributaries affected?
• Could the fault be in the equipment connected to Eclipse, rather than in Eclipse?
Are there alarms on other, connected equipment?
• Is it a hard or intermittent fault?
• Do alarms
confirm which end of an alarmed link is faulty?
• Could the weather (rain, ice, high wind, temperature) be a factor in the reported
fault?
NOTE:
If the fault suggests a rain fade or other weather related fade
condition and it matches the prevailing weather conditions, do not
take any action until the weather abates.
• Does link history suggest any fault trends?
• Does the fault history for the link indicate a likely cause?
• Is the Eclipse link newly installed?
• Has there been any recent work done on the link?
• Ensure that you have with you:
• Appropriate spares. Where an equipment failure is suspected, these should
include replacement modules/plug-ins and ODU. If an ODU is suspected then
local/national climbing safety requirements must be adhered to.
