Analyse historical data to identify possible causes and solutions |
2. Conduct remote testing to diagnose network fault | 2.1. Evaluate cable fault details and plan strategy to conduct remote testing 2.2. Conduct appropriate remote diagnostic test to isolate and diagnose the network fault 2.3. Determine the urgency and impact of fault and identify the required response time frame 2.4. Evaluate the diagnostic tests to determine the type, location and nature of network fault |
3. Dispatch fault-finding field personnel | 3.1. Prepare a fault report and forward to appropriate staff according to enterprise guidelines 3.2. Notify fault centre and arrange for the dispatch of technician to rectify fault 3.3. Notify customer of fault progress and arrange for fault clearance time |
Required Skills
Required skills |
communication skills to liaise with internal and external personnel on technical and operational matters literacy skills to interpret technical documentation, such as equipment manuals and specifications numeracy skills to take and analyse measurements planning and organisational skills to organise and maintain equipment problem solving skills to solve equipment and logistics problems task management skills to work systematically with required attention to detail and adherence to all safety requirements technical skills to: perform fault clearance use diagnostic equipment use hand and power tools |

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 o f assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: methodically approach fault identification conduct tests appropriate to the type of fault identified interpret test results provide instructions to staff engaged in on site repair. |
Context of, and specific resources for assessment | Assessment must ensure: sites where remote investigation of cable network faults may be conducted use of fault-finding equipment currently used in industry relevant documentation that impact on cable network 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 remotely 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: ICTCBL4057A Test cable bearers ICTTEN4087A Undertake remote diagnosis and repair of network 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. |
