Use electrical skills when working with telecommunications networks


Application

This unit describes the skills and knowledge required to use electrical skills when working with analog and digital, cabling and wireless networks in telecommunications.

It applies to entry-level workers 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.


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 Connect, test and verify alternating current (AC) and direct current (DC) circuitry

1.1 Identify work health and safety (WHS) issues and notify appropriate personnel

1.2 Connect a series and a parallel circuit following safe work practices

1.3 Choose appropriate test equipment and measure voltage (V), current (I) and resistance (Ω) values for the electricity in these circuits

1.4 Use calculations to verify the flow of electrical current in these circuits

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) and 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 as required

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 typical digital circuit to show different characteristics

3. Perform cable selection

3.1 Compare basic transmission characteristics, resistance, impedance and effects of signal frequency of different types of cables and select the most appropriate type to suit application

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

Foundation Skills

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