NZQA Expiring unit standard 17397 version 6 Page 1 of 4 Title Demonstrate knowledge of basic concepts of telecommunications Level 2 Credits Purpose 7 This unit standard covers introductory knowledge of telecommunications for people entering the industry. People credited with this unit standard are able to demonstrate knowledge of the: – underlying concepts of telecommunications; – operation of a simple telephone and a basic facsimile machine; – underlying technologies used in telecommunications; and – operation and use of networks and systems in telecommunications. Classification Telecommunications > Telecommunications - Service Delivery Available grade Achieved Explanatory notes The knowledge covered by this unit standard is expected to be at an introductory and nonmathematical level, with the objective of introducing relevant terminology and giving a broad overview of telecommunications. This unit standard is Outcome 1 expiring Demonstrate knowledge of the underlying concepts of telecommunications. Outcomes and evidence requirements Evidence requirements 1.1 The underlying concepts are described in simple non-mathematical terms and with reference to their relevance to telecommunications, and stating units where appropriate. Range concepts – sound, frequency, wavelength, bandwidth, frequency spectrum, modulation, attenuation, bits and bit rates. Outcome 2 Demonstrate knowledge of the operation of a simple telephone and a basic facsimile machine. The Skills Organisation SSB Code 100401 New Zealand Qualifications Authority 2016 NZQA Expiring unit standard 17397 version 6 Page 2 of 4 Evidence requirements 2.1 The operation of a simple telephone is explained with the aid of a diagram and with reference to components, signalling, and the transmission of speech. Range 2.2 components – microphone, receiver, tone signalling, ringing, antisidetone control. The operation of a simple facsimile machine is explained with the aid of a diagram, and with reference to components, signalling methods, and the transmission of pictures. Range components – signalling, tone detection, paper path, scanning, modulation, receiving, printing. Outcome 3 Demonstrate knowledge of the underlying technologies used in telecommunications. Range descriptions in non-mathematical terms. Evidence requirements 3.1 Types of modulation and the principle of multiplexing as used in telecommunication systems are described with reference to process, input and output waveforms, advantages, and applications. 3.2 The concepts of impedance, termination, reflection, crosstalk, noise, and signal level are described in non-mathematical terms and in relation to transmission media. 3.3 The transmission media employed in telecommunications are described with reference to general characteristics, structure, and applications. This unit standard is Range transmission media – unshielded twisted pair from audio through to Categoryexpiring 5, coaxial cable, fibre optic cable, analogue and digital microwave relay systems, cellular radio, microcell networks for Local Area Networks (LANs). 3.4 Digital transmission of data is compared to analogue transmission. Range 3.5 reference to – signal waveforms, bandwidth requirements, errors, tolerance to noise, line coding. Basic components and concepts of a data network are described with reference to the operation of the network. Range components and concepts – computer, file server, modem, channel access and collision avoidance; bus, ring, and star topologies.

Range descriptions in general terms to show the place of the networks or services in the overall telecommunication structure, without specific details of network structures and protocols. Evidence requirements 4.1 The Public Switched Telephone Network (PSTN) is described in terms of its operation and the services provided. Range 4.2 Data network services are described in terms of their operation, the services provided, and the key features of each. Range 4.3 data network services – leased data services, packet switch network, Integrated Services Digital network (ISDN), Frame Relay, Asynchronous Transmission Protocol (ATM). Radio network services are described in terms of their operation, the services provided, and the key features of each. Range 4.4 PSTN – switching plan and topology, Private Automatic Branch Exchanges (PABX), bandwidth limitations. radio network services – mobile radio, cellular network, personal communications systems (PCS).

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards. Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards. Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
