ICTTEN303
Locate, identify and rectify recurrent network faults


Application

This unit describes the skills and knowledge required to use systematic and logical fault-finding techniques according to all safety requirements and work practices.

It applies to individuals working as cablers and technicians who install and maintain a broad range of telecommunications networks.

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. Prepare for fault- finding activity

1.1 Prepare for given work according to work health and safety (WHS) and environmental requirements

1.2 Arrange access to site according to required procedure

1.3 Locate existing and potential site hazards

1.4 Contact customer to verify nature of recurrent fault and the network type

2. Conduct activities for recurrent network fault- finding

2.1 Analyse fault history using fault records to establish nature of fault

2.2 Select test equipment and conduct appropriate test to identify potential faults ensuring the diagnostic process does not compromise the integrity of the network element or system

2.3 Evaluate test results to determine relevant symptoms of recurrent fault using appropriate methods and appropriate process

2.4 Locate probable cause, type and location of the fault

2.5 Rectify fault or escalate to appropriate level

3. Report fault-findings and solutions

3.1 Prepare customer report on the diagnostic procedure, fault identification and fault clearance

3.2 Update fault records database

3.3 Restore worksite to the customer’s satisfaction

3.4 Notify customer and obtain sign-off

Evidence of Performance

Evidence of ability to:

discuss faults with clients

test telecommunications networks to identify faults

identify and rectify recurrent faults

conduct and report on a fault-finding task in a telecommunications network for a range of faults

use systematic and logical fault-finding techniques in telecommunications networks and field testing procedures to particular workplace situations

comply with all related work health and safety (WHS) requirements and work practices

notify customer when work has been complete and obtain sign off.

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:

outline application of Ohm’s law, impedance and reactance formulas to solve alternating current (AC) electrical problems when diagnosing faults

summarise behaviour of faulty network elements, including symptoms and impact on network

clarify interpretation of test results and network element/system specifications

outline the operation and purpose of testing equipment

explain the operation of transformers

provide a summary of telecommunications networks

describe performance testing and fault-finding techniques of telecommunications networks

summarise systematic and logical fault-finding

describe types of power sources used in telecommunications networks.


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 network testing and fault-finding may be conducted

line transmission, optical and radio measurement equipment currently used in industry

system documentation, and other site-related documentation necessary to conduct tests and fault-finding investigations.

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