ICTTEN607
Analyse and organise repair of highly complex telecommunications network faults

Assessment tool

Version 1.0
Issue Date: May 2024


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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

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. 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 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.

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).

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.
