Design communications wiring systems for customer premises

Assessment tool

Version 1.0
Issue Date: March 2024


Cablers installing cabling systems apply the skills and knowledge in this unit.

The unit 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 ICTDRE4166A Integrate customer digital reception equipment.

This unit describes the performance outcomes, skills and knowledge required to design a smart cable wiring system for customer premises.

All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an Australian Communications and Media Authority (ACMA)-accredited registrar. ACMA open registration with appropriate industry endorsements is essential.

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.

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:

capture customer functional needs for cabling system

apply industry standards, regulations and codes when designing the wiring system for customer premises

develop a detailed design in compliance with industry practices, including signal losses and/or expected measurements that need to be achieved at wallplates

document the design, including a bill of materials, schedule of work and associated costs.

Context of and specific resources for assessment

Assessment must ensure:

candidate is provided with a contemporary dwelling design, which covers all functional requirements of a modern home

candidate has 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 communicating with the customer

review of the planning sheets used by the candidate in developing the design

oral and written questioning to assess candidate skills and knowledge.

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.
