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.
It includes inspecting and servicing line and cable routes, diagnosing identified line and cable faults, and repairing line and cable faults to the standards specified to ensure system integrity.
Work is performed under minimal supervision, generally within a team environment.
It involves the application of routine operational principles and procedures when maintaining aerial signal/telecommunications lines and cables, as part of workplace activities across a variety of operational contexts within the Australian rail system.
People achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and to comply with relevant codes of practice and/or guidelines.
Operators of mechanised equipment must have undertaken training and, where appropriate, hold the relevant licence, permit or certificate and be recognised as competent for the class of machinery being used.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes.
Performance criteria describe the performance needed to demonstrate achievement of the element.
Inspect and service line and cable routes
Routes are inspected and recorded, and arrangements are made for the removal of any obstructions, damage or infringing vegetation to provide free access to cables/aerials
Hazards are identified, risks are assessed and risk control measures are implemented
Routes are physically inspected to determine breaks, misalignments, damage and insulation wear requiring repair
Poles are inspected for deterioration and a safety assessment is made
Diagnose line and cable faults
Permission to test isolated equipment is confirmed prior to work being undertaken
Probable location of fault is identified from visual inspection and circuit tests are conducted to isolate fault area
Nature of fault is identified from further tests and corrective action required is identified to enable appropriate arrangements for resources and for work to be performed
Disconnection/insulation procedures are applied to enable maintenance work to be performed in isolation to systems where lines are in close proximity to high voltage services
Repair line and cable faults
Worksite is made safe in accordance with organisational safety requirements to enable repair work to be safely undertaken
Aerial lines/cables are repaired to operational and technical requirements using appropriate jointing or replacement/repair procedures
Repaired/replaced line/cable is tested to specified standards to ensure conformity to operational and technical requirements
Appropriate personnel are notified of completed repairs/replacement and appropriate documentation is completed and processed in accordance with organisational requirements and returned to appropriate organisation/department as required

As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.
As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment.
Assessment must occur in workplace operational situations or, where this is not available, in simulated workplace operational situations that replicate rail workplace conditions.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Resources for assessment include:
a range of relevant exercises, case studies and/or simulations
relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry
applicable documentation including workplace procedures, regulations, rail industry standards, codes of practice and operation manuals.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range is restricted to essential operating conditions and any other variables essential to the work environment.
Non-essential conditions can be found in the Companion Volume Implementation Guide.
