ICTTEN316 — Conduct basic tests and analyses of telecommunications copper cabling

Elements & performance criteria

Performance evidence

• select, set-up and operate test instruments for three different cable types from the following list: - structured cabling verification/qualification tester - wire mapper - oscillator and probe - spectrum analyser - DVB-T/S2 analyser - multimeter – analog and digital - time-domain reflectometer (TDR) - asymmetric digital subscriber line (ADSL)/very-high-bit-rate digital subscriber line (VDSL) test instruments
• select appropriate instrument test cables and adaptors to suit test equipment for three different cable types and: - determine safety of cables to be tested (i.e. live or inactive) - identify calibration status of selected devices - confirm test results are within acceptable operational parameters.
• Note: Evidence must be provided at least once when a specific volume or frequency is not stated.

Knowledge evidence

• relevant legislation, regulations, codes, standards, rules, guidance notes and other formal agreements that impact on work, in particular: - AS/CA S008:2010 Requirements for customer cabling products - AS/CA S009:2013 Installation requirements for customer cabling (Wiring Rules) - AS/NZS 1367:2016 Coaxial cable and optical fibre systems for the RF distribution of digital television, radio and in-house analog television signals in single and multiple dwelling installations - AS/NZS 3000:2018 Electrical installations known as the Australian/New Zealand Wiring Rules - AS/NZS 3080:2013 Information technology - Generic cabling for customer premises (ISO/IEC 11801:2011, MOD) - AS/NZS 3084:2017 Telecommunications installations – Telecommunications pathways and spaces for commercial buildings - National Construction Code - work health and safety (WHS) regulations pertaining to electrical and electromagnetic telecommunications systems including energy supply sources
• different copper cable types utilised to match transmitted and received signals
• testing concepts and parameters used by test instruments including: - impedance, resistance, mismatches, crosstalk, reflections, ACR, spectrum, bandwidth, modulation depth, intermodulation, signal delay, group delay, normalisation, linearity, TDR, clock, jitter, latency, ping, signal to noise ratio (SNR), simplified Fourier analysis concepts, eye patterns, PAM4 or SDI, QAM patterns/constellations, MER, BER, FEC, signal losses, noise, interference, data rates, traffic, upload/download testing, signal levels, dBs, dBm, dBμ, dBr, dBμV
• testing acronyms including expansion and meaning
• common tests utilised with each copper cable telecommunication system
• telecommunications systems utilised in the telecommunications industry including: - telephone/voice over internet protocol (VoIP) systems - mobile phones, security systems - closed-circuit television (CCTV) systems - fire protection systems - structured cabling systems - local area network (LAN) equipment, telemetry - equipment control and monitoring systems - automation control systems - entertainment and control systems - radio communications - wi-fi - radio links - satellite and digital television reception - private automatic branch exchange (PABX)
• technical standards as applicable to copper cable systems
• test devices as applicable to copper cables in each transmission medium
• purpose and use of test results
• solid core cable versus stranded core.

Foundation skills

• Learning: Identifies, plans and implements strategies using knowledge attained
• Reading: Analyses and consolidates information and data from sources, against defined criteria and requirements, and checks for accuracy and completeness Recognises and interprets textual information to determine specific information about security incidents
• Writing: Develops material for a specific audience, using clear and detailed language in order to convey explicit information
• Oral Communication: Articulates information clearly, using specific and relevant language suitable to audience to convey recommendations and provide verbal reports Uses listening and questioning techniques to confirm understanding of WHS and operational testing
• Numeracy: Extracts and evaluates the mathematical information embedded in a range of technical specifications and manuals
• Navigate the world of work: Accepts responsibility and ownership for the task and makes decisions on completion parameters and the need for coordination with others Takes personal responsibility for following explicit and implicit policies, procedures and legislative requirements
• Interact with others: Selects form, channel and mode of communication for a specific purpose relevant to own role Ensures stakeholders are aware of WHS identified risks for task
• Get the work done: Plans strategic priorities and outcomes within a flexible, efficient and effective context, in a diverse environment exposed to competing demands Gathers and analyses data, and seeks feedback, to improve plans and processes Makes decisions in a complex and diverse environment, using input from a range of sources Explores and incubates new ideas through unconstrained analysis and critical thinking, to develop and improve enterprise controls
