2.3 Conduct tests according to selected test equipment operating instructions and safety requirements, and ensure diagnostic process aligns to customer service requirements
2.4 Identify and test for fault efficiently and sustainably
2.5 Evaluate test results to determine cause of fault/s using appropriate methods and processes
|
|
3. Rectify fault
|
3.1 Carry out work health and safety (WHS) activities prior to entering a pit or manhole and protect underground assets prior to excavation
3.2 Physically locate fault position in a length of cable or buried joint
3.3 Rectify fault or escalate to appropriate level
3.4 Discuss and document established methods for dealing with unexpected situations with appropriate personnel
3.5 Confirm that current standard of performance for copper cables will be viable after fault remediation work
3.6 Confirm integrity of repaired fault using appropriate carrier testing processes
|
|
4. Report fault-findings and rectification
|
4.1 Report fault identification and fault clearance
4.2 Update fault records
4.3 Restore worksite to customer satisfaction and acceptable industry standards
4.4 Notify customer and/or relevant parties to obtain sign-off
|
