5.4.1 Before Going to Site 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, 9500 MPR type, fre-
quency band, high/low end ODU, capacity modulation and configuration (nonprotected,
protected, diversity). Ask:
• Is just one 9500 MPR link affected, or a number of links in the same geographi-
cal 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 9500 MPR, rather than in
9500 MPR? 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?
