Use electrical skills in telecommunications work

Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills and knowledge required for an entry- level worker to use electrical skills, working with analog and digital, cabling and wireless networking in telecommunications.

It applies to individuals who undertake basic testing, circuit building, and evaluation of cable and wireless devices, and who may work in domestic, commercial or industrial situations.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

ELEMENT

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Connect up, test and verify DC and AC circuitry

1.3 Choose appropriate test equipment and measure values of electrical quantities of circuits

1.4 Use calculations to verify measured values of electrical quantities in a series and in a parallel circuit configuration

1.5 Compare measured values to calculated values, and determine reasons for any variations

1.6 Measure low voltage (LV), extra low voltage (ELV) or telecommunications network voltage (TNV) to determine if values are within equipment or power supply specifications

1.7 Use appropriate test equipment to measure AC voltage (multimeter) or AC current (clamp meter) in a safe manner that does not require an LV circuit to be disconnected

1.8 Test residual current devices (RCD) or earth leakage devices to ensure they are operational prior to working with AC mains powered equipment, power supplies and tools

1.9 Evaluate results and determine probable faults, if relevant

2. Evaluate analog and digital signals

2.1 Compare characteristics of an analog signal and a digital signal

2.2 Produce a layout using building blocks to represent a typical analog and a digital circuit showing different characteristics between an analog signal and a digital signal

2.3 Produce 4-bit binary codes with their decimal equivalent to represent output voltages of a digital to analog converter

2.4 Choose appropriate test equipment and measure output voltage of a digital device for high and low logic states

3. Perform cable selection

3.1 Compare basic transmission characteristics of different types of cables used in telecommunications and select the most appropriate cable type to suit application characteristics

3.2 Connect two devices with a patch cable and test the connection

Evidence of ability to:

use fundamental electrical principles to solve basic AC and DC electrical problems

connect and test an AC and DC circuit

evaluate and compare characteristics of analog and digital signals

compare and select cables according to transmission characteristics.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

describe principles of AC and DC electricity and how it impacts telecommunications work including:

AC and DC electrical SI units of measurement

work health and safety (WHS) issues

Ohm’s law and other relevant calculations

circuit configuration

identify and describe common AC and DC faults, fault finding techniques and use of testing equipment

explain application of binary to decimal conversion and vice versa

describe principles of analog and digital electronics and building blocks common to analog and digital circuits

explain the distinction between analog and digital signals and devices

explain encoding techniques and their application in wired, wireless and optical communications systems

outline features and applications of unshielded twisted pair (UTP), coaxial and fibre cables

list typical electronic devices, cable types and their applications

explain modulation techniques used in wired, wireless and optical communications systems

explain techniques to convert analog to digital and digital to analog

describe characteristics of signal transmission

list and describe common telecommunications cables and the characteristics of use and application.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the Telecommunications Network Engineering field of work and include access to:

appropriate AC and DC testing equipment

manufacturer's documentation and equipment

safety equipment.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
