Required knowledge

ACMA Competency Requirements for Telecommunications Cabling Provider Rules

features and operating requirements of test equipment

information required to operate equipment according to a test specification

legislation codes of practice and other formal agreements that impact on the work activity

manufacturers requirements for safe operation of testing tools and equipment

specific OHS requirements relating to the activity and site conditions

test methods and performance requirements

typical issues and challenges that occur on site

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

identify different faults using simple checks tests and faultfinding 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 faultfinding equipment currently used in industry

relevant regulatory and equipment documentation that impact on cable system testing and faultfinding 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 handson project completed by the candidate

review of an oral and written report including test results and faultfinding 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

ICTCBLA Joint metallic conductor cable on customer premises

ICTCBL2016A Joint metallic conductor cable on customer premises.

Aboriginal people and other people from a nonEnglish 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
