ICTNPL4109A
Evaluate the capability of access networks

This unit describes the performance outcomes, skills and knowledge required to gather information on the types of access networks and evaluate their capability to meet present and future demands. It involves the evaluation and comparison of competing access network technologies. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

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.

explain the key technologies that make up the access network

interrogate databases and investigate different audit requirements

source the equipment that will be used across the spectrum of access network technologies

technical skills to select and compare benefits and limitations of access network technologies

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.
