Locate and identify cable system faults

Assessment tool

Version 1.0
Issue Date: April 2024


Technical staff apply the skills and knowledge in this unit to locate and rectify communications cable system faults, including local area networks (LAN) and wide area networks (WAN). Their roles could include carrying out installation, maintenance and cable upgrades including structured cabling and network cabling. They may make use of test routines and databases.

This unit describes the performance outcomes, skills and knowledge required to locate and identify cable system faults in communications cables at enterprise and customer premises sites. The cable types may be telecommunications, voice or data cabling.

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.

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:

identify different faults using simple checks, tests and fault-finding methodology

determine and rank likely causes of fault

provide fault rectification solutions to customer

rectify faults

escalate unresolved faults to other parties for resolution

comply with all related OHS requirements and work practices.

Context of, and specific resources for assessment

Assessment must ensure:

sites where cable system tests may be conducted

use of fault-finding equipment currently used in industry

relevant regulatory and equipment documentation that impact on cable system testing and fault-finding activities.

Methods of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

review of a hands-on project completed by the candidate

review of an oral and written report, including test results and fault-finding methodologies

direct observation of the candidate locating and identifying cable system faults.

Guidance information for assessment

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

ICTCBL2016A Joint metallic conductor cable on customer premises.

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.
