ICTDRE3249A
Develop integrated digital reception systems

This unit describes the performance outcomes, skills and knowledge required to develop integrated digital reception system applications, topologies, devices and capabilities, and system programming methods. The unit also covers the use of diagnostic tools and documentation of developed systems.The skills and knowledge described in this unit do not require a licence to practice in the workplace. Practice in the workplace and during training are subject to work health and safety (WHS) regulations and codes of practice.

Application

This unit applies to cablers who install digital reception equipment and cabling systems. It applies to emerging opportunities in domestic and small to medium enterprise information technology.

The digital reception stream in ICT qualifications has related units, such as ICTDRE3248A Design communications wiring systems for customer premises.

Evidence Required

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:

implement WHS procedures and practices when developing an integrated system

apply sustainable energy principles and practices when developing an integrated system

determine the types and location of loads and control devices

use load calculations to correctly determine the number of network and current requirements

place system devices appropriately in the system scheme

check programming and diagnostic tools

apply appropriate modes of programming to develop the integrated system

follow manufacturer instructions and recommendations in programming devices and setting load operating parameters

develop an integrated system to comply with regulator, safety and project requirements

download program to network successfully

use diagnostic tools to locate and correct system defects, faults and anomalies

document and back up an integrated system during the following stages of the project:

at preparation

at programming

at completion.

Context of and specific resources for assessment

Assessment must ensure:

a typical contemporary dwelling into which a digital system will be developed

availability of all functional requirements of a modern home

access to contemporary digital equipment

access to all current standards, codes and regulations.

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 installing a digital reception system

direct observation of the candidate conducting signal measurement and adjusting for optimal performance

oral or written questioning of the candidate to assess knowledge of complex digital reception systems

oral or written questioning of the candidate to assess knowledge of test methods and performance requirements.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTTEN4229B Design, install and configure a customer smart technology network.

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.
