ICTTEN508
Locate, diagnose and rectify complex faults


Application

This unit describes the skills and knowledge required to identify faults in upstream or downstream services that may require involvement of third party providers.

It applies to individuals working as telecommunications officers, installers, maintenance staff, and manufacturer or equipment specialists. They must work closely with other personnel and rectify technical faults in a timely manner.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

2.4 Diagnose fault in the shortest time possible with minimum inconvenience to other client activity

2.5 Provide regular progress reports to clients

2.6 Raise fault identification to a national support level within a specified timeframe, if required

2.7 Undertake guidance from national support in fault diagnosis as required

2.8 Negotiate any necessary system downtime with clients

3. Rectify fault

3.1 Determine options to rectify fault including any system downtime and present to client for decision

3.2 Rectify fault totally, partially or provide temporary solution

3.3 Replace or repair faulty parts or equipment according to service agreement

3.4 Reprogram equipment as required

3.5 Dismantle and remove any temporary service in a safe and efficient manner where appropriate

3.6 Perform repair under national support guidance as required

3.7 Perform routine checks to identify likelihood of further or likely problems

3.8 Rectify any further problems identified, or bring to the attention of the customer for decision on further action

4. Clean up worksite and complete records

4.1 Produce a report on fault diagnosis and rectification

4.2 Remove and dispose of waste and debris from worksite according to environmental requirements

4.3 Ensure changes made to work area during fault repair are restored to client’s satisfaction

4.4 Complete all records, and explain and justify faults and rectification action taken

Evidence of Performance

Evidence of ability to:

methodically analyse fault details and diagnose potential faults

conduct advanced tests to determine complex network faults

isolate and locate faults logically

rectify faults using appropriate organisational procedures and work health and safety (WHS) requirements

comply with all related WHS requirements and work practices.

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:

explain fault escalation procedures

describe the most appropriate fault-finding techniques and test equipment required

identify fault types and rectification methods

list safety requirements and standards

define the function of service agreements

outline types of networks and equipment including:

access

broadband deployment

cabling

customer premises’ equipment (CPE)

internet protocol (IP) networks for enterprise and customer systems and installations

local area networks (LANs)

telephony

wide area networks (WANs)

outline workplace environment and practices.


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:

sites on which fault diagnostics may be conducted

testing equipment currently used in industry

relevant regulatory and equipment documentation impacting complex fault repairs.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
