Required Skills
Required skills |
analytical skills to interpret test equipment settings and readings communication skills to liaise with customers to ensure requirements are known and can be met within timeframes literacy skills to interpret technical specifications and related documentation numeracy skills to make calculations and necessary calibration changes planning and organisation skills to arrange site access and equipment delivery arrangements according to schedule safety awareness skills to: apply precautions and required action to minimise, control or eliminate hazards that may exist during work activities select and use required personal protective equipment conforming to industry and occupational health and safety (OHS) standards work systematically with required attention to detail without injury to self or others, or damage to goods or equipment technology skills to correctly handle, connect and calibrate test equipment |
Required knowledge |
cabling types, connectors and cabling structures connections to carrier infrastructure or equipment, such as main distribution frame (MDF) or customer interface units (CIU) electrical and/or optical properties to be measured overview knowledge of customer premises equipment typical performance parameters and typical faults that may be encountered in customer equipment and related connection and transmission media various test equipment types suitable for tests to be made |
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: perform tests on cable and equipment use a range of test devices interpret test results rectify a range of faults and escalate to the appropriate level if required report on the completed cable and system test. |
Context of and specific resources for assessment | Assessment must ensure: sites where cable and system tests may be conducted use of cable and system testing equipment currently used in industry relevant regulatory and equipment documentation that impact on cable and system testing installation 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 performing cable and system test on customer premises review of reports completed by the candidate for different test examples and situations oral or written questioning to assess knowledge of cable and systems tests. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTCBL3015A Locate and identify cable system faults. 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. |
