Application
Technical officers or engineers from private and public organisations apply the skills and knowledge in this unit. They combine technical design skills with broader organisational skills to assess planning requirements of various access network technologies within a telecommunications network to meet future customer demands. Technical officers or engineers may be responsible for small projects or parts of larger projects and for the operation and engineering work in the deployment or conversion to internet protocol (IP) based technologies of the telecommunications network in general. |

Required knowledge |
detailed knowledge of: typical access network technologies the elements and architecture of the various access networks typical problems and challenges that describe the capabilities of the various access networks |
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: evaluate the capability and limitations of the various access network technologies for present and future needs source the equipment that will be used across the spectrum of access network technologies outline the product offerings allowable across all competing access network technologies. |
Context of and specific resources for assessment | Assessment must ensure: network design documentation and other site related documentation equipment specifications live network or training facilities organisational guidelines networked computers networked telecommunications components. |
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 evaluating the capability of an access network review of reports completed by the candidate for differing access network equipment and technologies oral or written questioning to assess knowledge of equipment, technologies and the various product offerings as used within the access network. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTNPL4108A Plan the deployment of access network architectures. 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. |
