Elements and Performance Criteria

1. Prepare for fault- finding activity
   • Prepare for given work according to work health and safety (WHS) and environmental requirements
   • Arrange access to site according to required procedure
   • Locate existing and potential site hazards
   • Contact customer to verify nature of recurrent fault and the network type
2. Conduct activities for recurrent network fault- finding
   • Analyse fault history using fault records to establish nature of fault
   • Select test equipment and conduct appropriate test to identify potential faults ensuring the diagnostic process does not compromise the integrity of the network element or system
   • Evaluate test results to determine relevant symptoms of recurrent fault using appropriate methods and appropriate process
   • Locate probable cause, type and location of the fault
   • Rectify fault or escalate to appropriate level
3. Report fault-findings and solutions
   • Prepare customer report on the diagnostic procedure, fault identification and fault clearance
   • Update fault records database
   • Restore worksite to the customer’s satisfaction
   • Notify customer and obtain sign-off

Performance Evidence

Evidence of ability to:

discuss faults with clients

test telecommunications networks to identify faults

identify and rectify recurrent faults

conduct and report on a fault-finding task in a telecommunications network for a range of faults

use systematic and logical fault-finding techniques in telecommunications networks and field testing procedures to particular workplace situations

comply with all related work health and safety (WHS) requirements and work practices

notify customer when work has been complete and obtain sign off.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
