Elements and Performance Criteria

1. Research fault background
   • Analyse current, relevant data and previous actions taken by other personnel
   • Research areas of similarity to network fault
   • Develop commercial and technical strategies with equipment vendor and NOC for diagnosing the fault
   • Address and discuss all work health and safety (WHS) issues with relevant personnel
   • Obtain appropriate clearance and access to network equipment, software and firmware codes where they apply
2. Diagnose fault
   • Apply a methodical approach to isolate and diagnose the problem
   • Simulate fault in a workshop or laboratory environment if possible
   • Seek support from the vendor while investigation progresses
   • Instruct on-site technical staff to run appropriate tests and analyse results
   • Diagnose network fault using established methodical strategies in a timely fashion without undue disruption to other services
   • Develop a plan to rectify the fault
3. Organise fault rectification
   • Recommend fault rectification plan to the NOC, including any outages, seek approval and adjust plans accordingly
   • Instruct on-site repairers with clear and methodical instructions on how to proceed in rectifying the fault
   • Organise replacement or repair of faulty equipment with appropriate advice from vendors and manufacturers
   • Reconfigure replaced or repaired equipment and test rectified fault to ensure required performance
   • Notify NOC, affected customers and on-site staff of fault rectification
4. Report and document fault details and rectification
   • Notify vendors of repair details and recommend changes to equipment design where appropriate
   • Conduct cause and effect studies and forward results to the appropriate area for necessary action
   • Complete all administrative tasks and prepare a report including deficiencies, analysis and recommendations

Performance Evidence
