3. Splice coaxial cable

3.1 Strip and core hard-line coaxial cable, according to specifications, to required length using appropriate tools

3.2 Select appropriate kit to match type of hard-line coaxial cable in use and splice according to manufacturer recommendations

3.3 Seal all splices according to industry specifications

4. Terminate coaxial cable

4.1 Prepare coaxial cable for termination, according to specifications, using appropriate tools

4.2 Select connectors to match type of coaxial cable in use and terminate according to industry standards

4.3 Install network device chassis/housing in correct orientation according to design

4.4 Prepare centre pins of cable and connector, and cut according to vendor specifications

4.5 Terminate connectors to torque according to manufacturer recommendations to prevent RF leakage, and ensure seizure screws are tightened

4.6 Seal all terminations according to industry specifications

5. Complete installation operation

5.1 Place cables in pit and/or mount on aerial strand according to manufacturer instructions and industry guidelines, and check that no safety hazards are evident

5.2 Attach fitted off device aerially or underground according to manufacturer specifications or work instructions

5.3 Reinstate site, and remove waste and debris for disposal according to environmental requirements and maintain safe worksite conditions

6. Complete installation administration

6.1 Complete reports according to telecommunications carrier network policy

6.2 Update plans and records using appropriate symbols with details of installation

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance, but not explicit in the performance criteria.

Skill 

Description 

Reading

  • Reads familiar texts fluently, automatically recognising most everyday words and some specialised vocabulary

Writing

  • Sequences writing to produce cohesive text and uses layout consistent with text type

Oral Communication

  • Demonstrates awareness of choices for register, especially in situations that are familiar

Numeracy

  • Interprets and comprehends whole numbers and familiar or routine fractions, decimals and percentages
  • Selects and uses appropriate tools, hand-held devices, computers and technological processes

Navigate the world of work

  • Takes responsibility for decisions regarding when and how to complete tasks, and coordinate with or delegate to others
  • Takes personal responsibility for adherence to legal and regulatory responsibilities relevant to own work context, and draws attention to any issues that may affect self or others

Get the work done

  • Implements actions as per plan, makes slight adjustments if necessary, and addresses unexpected issues
  • Automatically implements standard procedures for routine decisions

Performance Evidence

The candidate must demonstrate the ability to perform the tasks outlined in the elements, performance criteria, and foundation skills, and to:

  • determine installation requirements
  • prepare site for hard-line coaxial cable installation
  • identify hard-line coaxial cable types
  • perform an in-line splice
  • terminate hard-line coaxial cable using specialised hand or power tools and equipment
  • terminate hard-line coaxial cable to network devices using:
  • a pin connector
  • 90- or 180-degree adaptors
  • housing to housing adaptor
