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.
Element | Performance Criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Analyse specialised optical device and prepare for integration in the network | 1.1 Obtain relevant legislation, codes, regulations and standards and follow work health and safety (WHS) and environmental requirements for the project work 1.2 Work safely according to relevant safety legislation and company work practices, identifying hazards and using personal protective equipment 1.3 Obtain plans and drawings of existing optical network from appropriate person and review potential locations for suitability of integrating additional hardware 1.4 Analyse and evaluate a range of integration options using device specifications which satisfy the customer’s network requirements 1.5 Prepare and submit the business case for adopting recommended integration solution 1.6 Prepare design plan with interconnection details to existing system and installation options and seek approval to proceed from customer 1.7 Undertake an impact risk assessment of the hardware integration with the network operations centre (NOC) and prepare for contingencies using contingency plan |
2. Integrate specialised optical device in the network | 2.1 Install and integrate specialised optical devices into existing network according to design plan 2.2 Test the network and evaluate results to verify optical network performance with integrated specialised optical devices in operation |
3. Document integration of the specialised optical device in dense wavelength division multiplexing (DWDM) network | 3.1 Produce an updated design plan and submit to customer with copies filed for later reference according to organisation’s policies 3.2 Prepare an evaluation report on network performance with specialised optical devices with recommendations for future enhancements 3.3 Notify NOC of job completion and obtain sign-off from appropriate person |
Evidence of ability to:
analyse a specialised optical device and prepare a design to integrate it with a network
integrate and test the device
document integration to the network and recommend enhancements
submit relevant documentation to appropriate personnel
comply with all related work health and safety (WHS) requirements and work practices.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
