Application
This unit describes the skills and knowledge required to install and terminate coaxial cable on client premises in communications applications, digital and analog, including master antenna television (MATV), cable television (CATV), closed-circuit television (CCTV), digital video broadcasting – terrestrial (DBVT), digital video broadcasting – satellite (DVB-S), data and video, including digital broadcasting, computer networks such as local area networks (LAN) and wide area networks (WAN), and multimedia.
It applies to technical staff who install and terminate coaxial cable for new installations, upgrades or the maintenance of existing networks in domestic, commercial and industrial installations on a client's premises.
All cabling work for clients in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an Australian Communications and Media Authority (ACMA) accredited registrar.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare to install and terminate coaxial cable | 1.1 Prepare for given work according to relevant legislation, codes, regulations and standards 1.2 Arrange access to site according to required procedure 1.3 Inform appropriate personnel of identified 1.4 Select coaxial cable 1.5 Check proposed route and bend radius to meet manufacturer’s specifications and industry standards 1.6 Test cable on drum for continuity and inspect visually for crushing and kinks 1.7 Discuss with client proposed method of installation and cable route, and adjust if necessary |
2. Install, terminate and test coaxial cable | 2.1 Maintain cable segregation to industry standards 2.2 Protect integrity of coaxial shield cable to ensure no loss of signal during operation and maintain bend ratios to not exceed manufacturer’s specifications and industry standard 2.3 Install cable securing hardware to ensure cable is not crushed or kinked while maintaining cable manufacturer's bend radius 2.4 Install cable following work health and safety (WHS) and environmental requirements, and complying with manufacturer’s specifications and industry standards 2.5 Terminate cable and perform type of termination specified in plan using safe work practices and according to manufacturer’s specifications 2.6 Test termination for transmission loss and signal levels, and re-terminate the coaxial cable if the transmission loss exceeds the manufacturer’s specifications 2.7 Record all measurements 2.8 Fit over-voltage protection devices to all cables with metallic component where required |
3. Remove termination waste from work area | 3.1 Clean work area thoroughly to minimise risk of injury from loose metal strands 3.2 Dispose of waste safely according to relevant environmental requirements 3.3 Restore worksite to client’s satisfaction |
4. Document installation | 4.1 Update plans and records with details of installation and test results 4.2 Show client completed work and ensure work matches agreed method of installation and cable route 4.3 Notify client of work completion and obtain sign off |
Evidence of Performance
Evidence of the ability to:
install and terminate coaxial cable types including RG6 quad shielded coaxial cable
install different connector types
conduct and interpret test results
verify the installation complies with manufacturer’s specifications and warranties
prepare a report for a client that documents the installation and test results
comply with all related work health and safety (WHS) requirements and work practices.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
identify and apply relevant legislation, regulations, standards and codes of practice associated with the installation of coaxial cables
describe the features of types of coaxial cable and the manufacturer's specifications that apply
describe the features and operating requirements of test equipment for coaxial cable
describe the information required to operate equipment according to a test specification
identify the manufacturer’s requirements for safe operation of coaxial cable tools and equipment
describe safety precautions when working with coaxial cable and radio frequency (RF) based systems
identify specific WHS requirements relating to the activity and site conditions
describe test methods and performance requirements
discuss the types and techniques for connecting and termination of coaxial cable, including:
compression termination
crimp termination
summarise the function of over-voltage protection devices
describe the transmission and propagation characteristics of coaxial cable
discuss typical issues and challenges that occur on site.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – cabling field of work and include access to:
special purpose tools, equipment and materials
sites where installation and termination of coaxial cabling may be conducted
equipment and personal protective equipment currently used in industry
testing equipment currently used in industry
relevant regulatory and equipment documentation that impacts on installation activities.
Note: All client cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an Australian Communications and Media (ACMA) accredited registrar. Assessment by a Telecommunications Industry Training Advisory Board (TITAB) registered assessor is recommended for this unit.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
