Test cables and systems on customer premises


Application

This unit describes the skills and knowledge required to test the performance of copper, optical fibre and telecommunications cable on customer premises for the purpose of commissioning, fault identification or routine maintenance. It includes ensuring a safe and secure work environment while work is being undertaken.

It applies to field officers, technicians or technical supervisors working for cablers, technicians, contractors or other service providers who carry out domestic, commercial or industrial installations in indoor and outdoor environments. Communications applications include digital and analog, telephony, data, video, digital broadcasting, computer networks, local area networks (LANs), wide area networks (WANs), power over ethernet (PoE) cable installations and multimedia.

Licensing, legislative, regulatory and certification requirements apply to telecommunications systems. All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. All cablers are required to register with an Australian Communications and Media Authority (ACMA) accredited registrar.


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 cable and system test

1.1 Establish purpose of test to be conducted on cables and systems based on customer complaints of faulty or poor system performance operations

1.2 Confirm ACMA (Australian Communications and Media Authority) requirements and methods for compliance with relevant legislation, regulations, codes and standards

1.3 Selectrequired tests according to site conditions, customer complaint documentation and manufacturer specifications

1.4 Arrange access to site and confirm service is available for testing

1.5 Select test equipment, tools and materials according to required industry testing standards

2. Perform tests

2.1 Use tools and test equipment according to manufacturer specifications and undertake tests required after initial analysis of customer complaints

2.2 Perform work safely to remove risk of injury to operator, other users and equipment

2.3 Perform checks and adjustments to ensure operating environmental factors will not prejudice test results

2.4 Perform optical time domain reflectometer testing to determine fibre and event characteristics according to meet customer or enterprise specifications and manufacturer warranties

2.5 Perform structured cabling certification testing to determine cable system characteristics according to customer or enterprise specifications and manufacturers warranties

2.6 Evaluate PoE circuits, cable lengths, copper conductor sizes, resistance versus power losses, environmental temperatures and likely power levels to ensure circuit current, voltage and power to the receiving device

3. Interpret test results and determine action

3.1 Read test results accurately and compare with manufacturer and site specifications for cable performance

3.2 Evaluate test results, taking into account measurement error margins against a known reference as required

3.3 Assess test results fairly and accurately using verifiable data

3.4 Rectify faults or escalate to appropriate person

4. Complete records and clean up site

4.1 Document test results and ensure test results remain current

4.2 Verify test results and provide to customer as required

4.3 Update site and installation files to ensure information on system performance is traceable including PoE standards

4.4 Reinstate site according to customer and company requirements

4.5 Notify customer and obtain sign-off

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance, but not explicit in the performance criteria.
