Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to design supporting infrastructure for telecommunications network installations.

This includes carrier grade switching, transmission and access equipment and associated media, power and monitoring equipment and alarm systems, fibre distribution hubs (FDHs), and remote power feeds.

Application of the Unit

Field officers, design technicians and technical supervisors from carriers, contractors and other service providers apply the skills and knowledge in this unit.

This unit may apply to switching, transmission and radio networks and the various transmission paths, including cable, optical fibre, radio, microwave and satellite.

This unit is one in a sequence of units that cover network design activities including:

design drawings and specifications

designing a dense wavelength division multiplexing (DWDM) system

designing infrastructure

estimating and quoting

site survey.

Licensing/Regulatory Information

Licensing, legislative, regulatory and certification requirements apply to working at heights. If an elevated work platform (EWP) is required, verify state or territory law requirements for a licence to operate an EWP. Users should confirm requirements with the relevant federal, state or territory authority.

If working at heights, achievement of the unit ‘CPCPCM2015A Work safely on roofs’ from the CPC08 Construction, Plumbing and Services Training Package fulfils this requirement.

Pre-Requisites

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to: conduct a site survey to identify infrastructure features, including: potential earthing locations cable routes locations for cables trays, data cabinets, telecommunication enclosures, and distributors design infrastructure for access network design protective earth and functional earth installations design power infrastructure design and monitor DC power distribution work.
Context of and specific resources for assessment	Assessment must ensure: site where installation of supporting infrastructure may be conducted use of plant, tools and equipment currently used in industry relevant regulatory and equipment documentation that impacts on work activities.
Method of assessment	A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct observation of the candidate designing metal superstructure to house equipment direct observation of the candidate designing protective earth and functional earth installations review of design drawings prepared by the candidate oral or written questioning to assess knowledge of design issues, types of systems and applications.
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTNPL4247A Apply compliance requirements to telecommunications work ICTTEN4241A Design network projects ICTTEN4242A Conduct site surveys to identify carrier installation requirements ICTTEN4243A Prepare design drawings and specifications for telecommunications installations ICTTEN4244A Estimate and quote for carrier telecommunications equipment installations ICTTEN4246A Design dense wavelength division multiplexing installations. Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs.
