Remotely locate and identify cable network faults


Application

This unit describes the skills and knowledge required to remotely locate and identify cable network faults in voice, video and data telecommunications applications using metallic and optical fibre cables.

It applies to technicians who are required to locate telecommunications cable faults in access networks. This may be done at a centralised testing office and make use of computer test routines and databases.

Work functions in the occupational areas where this unit may be used are subject to regulatory requirements. Refer to the Implementation Guide Companion Volume or the relevant regulator for specific guidance on requirements.


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. Verify fault report

1.1 Locate source of fault using available information and contacts to verify nature of fault as reported

1.2 Perform preliminary operational testing according to type of fault presentation, fault environment and enterprise guidelines to verify nature of fault

1.3 Analyse historical data to identify possible causes and solutions

2. Conduct remote testing to diagnose network fault

2.1 Evaluate cable fault details and plan strategy to conduct remote testing

2.2 Conduct appropriate remote diagnostic test to isolate and diagnose network fault

2.3 Determine urgency and impact of fault and identify required response time frame

2.4 Evaluate diagnostic tests to determine type, location and nature of network fault

3. Dispatch fault-finding field personnel

3.1 Prepare fault report and forward to appropriate staff according to enterprise guidelines

3.2 Notify fault centre and arrange for dispatch of technician to rectify fault

3.3 Notify client of fault progress and arrange for fault clearance time

Evidence of Performance

Evidence of the ability to:

methodically approach fault identification

conduct tests appropriate to the type of fault identified

interpret test results

provide instructions to staff engaged in on-site repair.

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:

describe the features and operating requirements of test equipment

identify appropriate tests to be performed

describe the legislation, codes of practice and standard procedures for cable network faults

specify health and safety requirements relating to fault finding in cable networks

identify typical issues and challenges that occur when performing remote tests and fault finding.


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 must be typical of those experienced in the telecommunications – cabling field of work and include access to:

sites where remote investigation of cable network faults may be conducted

fault-finding equipment currently used in industry

relevant documentation that impacts on cable network and fault-finding activities.

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