Application
This unit describes the skills and knowledge required to identify faults across all network types, with collaboration from the network operations centre (NOC), and resolve any problems.
It applies to individuals working as network engineers, telecommunications officers, installers, maintenance staff and manufacturers or equipment specialists. It also applies to NOC staff in advisory roles and technical rectification roles.
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. Research fault background | 1.1 Analyse current, relevant data and previous actions taken by other personnel 1.2 Research areas of similarity to network fault 1.3 Develop commercial and technical strategies with equipment vendor and NOC for diagnosing the fault 1.4 Address and discuss all work health and safety (WHS) issues with relevant personnel 1.5 Obtain appropriate clearance and access to network equipment, software and firmware codes where they apply |
2. Diagnose fault | 2.1 Apply a methodical approach to isolate and diagnose the problem 2.2 Simulate fault in a workshop or laboratory environment if possible 2.3 Seek support from the vendor while investigation progresses 2.4 Instruct on-site technical staff to run appropriate tests and analyse results 2.5 Diagnose network fault using established methodical strategies in a timely fashion without undue disruption to other services 2.6 Develop a plan to rectify the fault |
3. Organise fault rectification | 3.1 Recommend fault rectification plan to the NOC, including any outages, seek approval and adjust plans accordingly 3.2 Instruct on-site repairers with clear and methodical instructions on how to proceed in rectifying the fault 3.3 Organise replacement or repair of faulty equipment with appropriate advice from vendors and manufacturers 3.4 Reconfigure replaced or repaired equipment and test rectified fault to ensure required performance 3.5 Notify NOC, affected customers and on-site staff of fault rectification |
4. Report and document fault details and rectification | 4.1 Notify vendors of repair details and recommend changes to equipment design where appropriate 4.2 Conduct cause and effect studies and forward results to the appropriate area for necessary action 4.3 Complete all administrative tasks and prepare a report including deficiencies, analysis and recommendations |
Evidence of Performance
Evidence of ability to:
diagnose network faults using established methodical strategies without undue disruption to other services
recommend fault rectification plan to the network operations centre (NOC)
instruct on-site repairers
facilitate replacement or repair of faulty equipment with appropriate advice from vendors and manufacturers
facilitate final testing of rectified faults to ensure required performance
prepare report including deficiencies, analysis and recommendations.
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 fault escalation procedures
explain fault-finding techniques and use of test equipment
outline fault types and rectification
outline the operation of integrated packet optical transport networks (P-OTNs)
explain the use of International Telecommunication Union (ITU) ITU-T G.709 standard
explain network protocols
outline safety requirements and standards
explain service agreements
explain synchronous digital hierarchy (SDH)
summarise transmission control protocol (TCP)-internet protocol (IP)
summarise the following types of networks and equipment:
access
broadband deployment
cabling
customer premises’ equipment (CPE)
IP networks for enterprise and customer systems and installations
local area networks (LAN)
telephony
wide area networks (WAN).
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 should be typical of those experienced in the telecommunications networks engineering field of work and include access to:
a site where highly complex network faults may be demonstrated and analysed without jeopardising live traffic
equipment currently used in industry
design specifications and manufacturer's manuals and reference materials.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
