Description
This unit describes the performance outcomes, skills and knowledge required to use appropriate tools, equipment, software and protocols to design and build an internet protocol (IP)-based integrated voice network for small to medium enterprises.
Notes
Elements and Performance Criteria
1. Plan design concepts of a voice network for specified voice quality
- 1.1 Determine the design requirements of an IP-based voice network including the choice of network elements
- 1.2 Evaluate the various applications of real time protocols and of signalling protocols for an appropriate gateway
- 1.3 Design a site numbering plan including digit manipulation and path selection process
- 1.4 Plan and assign calling privileges as required
- 1.5 Predict VoIP call flow and potential impact on voice quality considerations and network performance
2. Design, configure implement and test voice protocols and interoperation of VoIP communications network
- 2.1 Produce the design layout of the voice network according to the design requirements
- 2.2 Design and configure a gateway and a gatekeeper to using H.323 protocol suite for dial plan resolution and call admission control for the network
- 2.3 Configure and test the use of real-time protocols, call management protocols and gateway signalling protocol in the network design
- 2.4 Analyse the function and interoperation of gatekeepers within an IP communications network
3. Design, configure and test a VoIP IP-to-IP call system
- 3.1 Analyse the IP-to-IP gateway features and functionality requirements for a given network design requirement
- 3.2 Configure the gatekeeper to support an IP-to-IP gateway
- 3.3 Configure and test the IP-to-IP gateway to provide address hiding, protocol and media interworking and call admission control implementations
- 3.4 Produce test results and evaluate against design requirements
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

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 VoIP network
configure and test for voice gateways
design site numbering plan, dial plans and priorities
use networking and network management tools
configure and test real time protocols, call management protocols and gateway signalling protocol in the network elements
implement voice systems and applications.
Context of and specific resources for assessment
Assessment must ensure access to:
site where network installation may be conducted
hardware and software
organisational guidelines
computers
stand-alone and lightweight WLAN controllers and AP
hardware and software LAN/WLAN 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
verbal 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 non-English speaking background may need additional support.
In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
