Application
This unit describes the skills and knowledge required to use tools, equipment, software and protocols to install or upgrade call processing network elements for secure and reliable internet protocol (IP)-based communications networks.
It applies to individuals with advanced information communications technology (ICT) skills who are working as advanced voice over internet protocol (VoIP) network support specialists, VoIP network engineers and VoIP systems installers.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Plan to implement enterprise IP communications | 1.1 Produce design considerations for planning and implementing IP-based voice communications networks 1.2 Produce a solutions plan to meet business expectations 1.3 Select the required resources to effectively install or upgrade voice management servers 1.4 Perform, test and evaluate the installation or upgrade of voice call management software against the solutions plan |
2. Plan, configure and test call processing network elements for a single-site deployment | 2.1 Produce a topology of the voice network and plan the location of the call processing network elements to best support the business requirements 2.2 Install and test voice servers to support user requirements, third-party session initiation protocol (SIP) phones and lightweight directory access protocol (LDAP) integration 2.3 Install and configure local area network (LAN) switches to support IP phones 2.4 Configure and test voice gateways according to gateway requirements to allow for internal calls and external calls and provide voice features 2.5 Configure and test the integration of voice servers with other media systems 2.6 Test and evaluate final configuration against the design requirements |
3. Manage security and privacy of IP voice network | 3.1 Produce design and installation templates for bulk deployment across the enterprise 3.2 Research and implement the use of a network support model to manage the performance and security of the IP voice network 3.3 Design and conduct simple security deployment scenarios to test the integrity and security of the voice network |
Evidence of Performance
Evidence of the ability to:
produce design plan and requirements of call processing network elements
configure and test voice gateways and local area network (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.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
summarise call processing network element technology
outline codecs and their protocols for use
explain configuration, verification and troubleshoot procedures to undertake:
basic router operation and routing
switch with virtual local area network (VLANs) and inter-switching communications
summarise design considerations and deployment schemes
explain interoperability of legacy private branch exchange (PBX) to internet protocol (IP) voice communications
outline internetwork operating system (IOS) and IP networking and network support models
summarise LAN and wide area network (WAN) implementations
outline network topologies, architectures and elements
summarise network, signalling and call management protocols
outline networking standards and protocols
summarise security deployment scenarios
explain voice applications and protocols
outline voice over internet protocol (VoIP) technologies.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the networking industry, and include access to:
site where network installation may be conducted
hardware and software
organisational guidelines
computers
stand-alone and lightweight WLAN controllers and access points (AP)
hardware and software LAN/WLAN voice technologies.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Reading | 1.4, 2.4, 2.6, 3.2 | Recognises and interprets complex technical information to determine and adhere to design requirements |
Writing | 1.1, 1.2, 2.1, 3.1 | Develops a broad range of material, including planning documentation, design and installation templates for a specific audience using clear and detailed language to convey explicit information, requirements and recommendations |
Numeracy | 1.3, 1.4, 2.2, 2.4-2.6 | Interprets numerical data in planning phase and undertakes measurements to evaluate performance and interoperability of network Uses mathematical formulas and calculations to estimate and plan resource requirements |
Get the work done | 1.1, 1.3, 1.4, 2.1-2.6, 3.2 | Demonstrates a sophisticated understanding of principles, concepts, language and practices associated with the digital world, and uses these to troubleshoot and understand the uses and potential of new technology Uses a broad range of strategies to store, access and organise virtual information, recognising that design choices will influence what information is retrieved and how it may be interpreted and used Is acutely aware of the importance of understanding, monitoring and controlling access to digitally stored and transmitted information Uses a mix of intuitive and formal processes to identify key information and issues, evaluate alternative strategies, anticipate consequences and consider implementation issues and contingencies May use formal analytical and lateral thinking techniques for identifying issues and generating and evaluating possible solutions |
