Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

  • analytical skills to identify and rectify faults in Ethernet transmission
  • communication skills to:
  • liaise with internal and external personnel on technical and operational matters
  • relate to work associates, supervisors, team members and clients
  • literacy skills to:
  • interpret technical documentation, such as equipment manuals, specifications and service orders
  • write reports using standard formats
  • research skills to gather data, observation and analysis of transmission issues
  • technical skills to conduct tests and operate test equipment

Required knowledge 

  • ethernet:
  • applications of ethernet in optical systems
  • architecture of ethernet systems
  • operation of ethernet within a telecommunications environment
  • organisational policy and procedures
  • testing techniques
  • familiarity with workplace and industry environment
  • specific OHS requirements relating to:
  • handling of optical fibre
  • personal safety issues
  • use of laser light sources

Evidence Guide

EVIDENCE GUIDE 

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:

  • plan to test an optical ethernet link
  • select and perform a testing regime on ethernet optical transmissions
  • analyse and document test results
  • comply with all related OHS requirements and work practices.

Context of and specific resources for assessment 

Assessment must ensure:

  • a telecommunications operations site with ethernet optical transmission system
  • test equipment currently used in industry.

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:

  • oral or written questioning of the candidate
  • direct observation of the candidate carrying out relevant measurements within an ethernet optical communication system
  • evaluation of written report prepared by the candidate outlining architecture components, testing regime and analysis of test results.

Guidance information for assessment 

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

  • ICTOPN4116A Use advanced optical test equipment
  • ICTOPN6129A Analyse optical transmission systems.

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.
