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

produce design plan and requirements of call processing network elements

configure and test voice gateways and LAN switches

evaluate voice call manager server requirements and design voice call systems and applications

implement voice systems and applications on voice call manager

manage security of voice network

Context of and specific resources for assessment

Assessment must ensure access to

site where network installation may be conducted

hardware and software

organisational guidelines

standalone and lightweight WLAN controllers and AP

hardware and software LANWLAN voice technologies

appropriate learning and assessment support when required

modified equipment for people with special needs

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 installing configuring and testing a new or updated network

evaluation of documentation prepared by the candidate outlining testing procedures test results recommendation to network changes and completion records

oral or written questioning of required knowledge

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended where appropriate

Assessment processes and techniques must be culturally appropriate and suitable to the communication skill level language literacy and numeracy capacity of the candidate and the work being performed

Indigenous people and other people from a nonEnglish speaking background may need additional support

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
