Qualification -
Unit of Competency ICTTEN4086A - Undertake routine maintenance of the telecommunications network
Description This unit describes the performance outcomes, skills and knowledge required to undertake routine maintenance of the telecommunications network. This planned maintenance ensures that network equipment is regularly serviced and is operating correctly, so that minor faults and potential problems are corrected before they develop into major defects and disruption to the network.Licensing, legislative, regulatory and certification requirements apply to working at heights, confined spaces, crane operation, rigging, driving and other operations involved in this unit. Users should confirm requirements with the relevant federal, state or territory authority.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application Field officers or technicians from carriers, contractors and other service providers apply the skills and knowledge in this unit.This unit involves routine maintenance of network plant and equipment in various telecommunications switching and transmission environments, including wide area networks (WAN), virtual private networks (VPN) and Core networks, using wireless, optical, broadband and Next Generation Networking (NGN) technologies.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 a detailed routine maintenance schedule

conduct and record routine maintenance activities procedures and techniques

test network equipment complying with site risk control, OHS, environmental, quality and communication requirements.

Context of and specific resources for assessment

Assessment must ensure:

sites on which routine maintenance may be conducted

use of maintenance tools and test instruments currently used in industry

relevant regulatory and equipment documentation that impacts on maintenance 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 carrying out routine maintenance activities

review of maintenance reports completed by the candidate for different sites and equipment

oral or written questioning to assess knowledge of maintenance procedures.

Guidance information for assessment

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

ICTTEN4081A Locate, diagnose and rectify 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.
