Description
This unit involves the skills and knowledge required to maintain aerial signal/telecommunications lines and cables in accordance with safeworking and regulatory requirements and workplace procedures, including inspecting and servicing line and cable routes, diagnosing any identified line and cable faults and repairing any line and cable faults to the standards specified to ensure system integrity. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Elements and Performance Criteria
1Inspect and service line and cable routes
- 1.1 Routes are inspected and recorded and arrangements are made for the removal of any obstructions, damage, infringing vegetation to provide free access to cables/aerials
- 1.2 Routes are physically inspected to determine any breaks, misalignments, damage and insulation wear requiring repair
- 1.3 Poles are inspected for deterioration and a safety assessment is made
2Diagnose line and cable faults
- 2.1 Permission to test isolated equipment is confirmed prior to any work being undertaken
- 2.2 Probable location of fault is identified from visual inspection and circuit tests are conducted to isolate fault area
- 2.3 The nature of the fault is identified from further tests and corrective action required is identified to enable appropriate arrangements for resources and for work to be performed
- 2.4 Disconnection/insulation procedures are applied to enable maintenance work to be carried out in isolation to systems where lines are in close proximity to high voltage services
3Repair line and cable faults
- 3.1 Work site is made safe in accordance with organisations safety requirements to enable repair work to be safely undertaken
- 3.2 Aerial lines/cables are repaired to operational and technical requirements using appropriate jointing or replacement/repair procedures
- 3.3 Repaired/replaced line/cable is tested to specified standards to ensure conformity to operational and technical requirements
- 3.4 Appropriate personnel are notified of completed repairs/replacement and appropriate documentation is completed in accordance with organisations requirements and returned to appropriate organisation/department as required
