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. 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 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.
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.
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.
