Modification History

Release	Comments
Release 1	This version first released with ICT Information and Communications Technology Training Package Version 2.0.

Application

This unit describes the skills and knowledge required to safely install, maintain and modify communications cabling required according to the Australian Communications and Media Authority’s (ACMA) ‘Restricted’ Cabling Provider Rule on customers premises for cabling terminated on sockets and network termination devices (NTD) of indoor and external metallic cable in either aerial or underground situations.

It applies to individuals who may provide services to connect telecommunications devices including telephony systems, security alarm panels and fire control panels in either a new cable installation or upgrade of cable capacity for an existing network or subsystem for convergence to Next Generation Networks (NGN) applications. Customers are typically domestic premises, small offices, home offices and small business premises. Generally large commercial and industrial premises are excluded except in special circumstances where the cabling is behind a compliant device and is not via jumperable distributors or patch panels.

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 ACMA-accredited registrar.

Pre-requisite Unit

ICTWHS204 Follow work health and safety and environmental policies and procedures

ICTTEN201 Use electrical skills in telecommunications work

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. Plan for restricted cabling work	1.1 Prepare for restricted cabling work within the ACMA regulatory environment, cabling environment, cable type, cable identification, termination systems, earthing and protection, records and according to requirements of relevant legislation, codes, regulations and standards 1.2 Identify building infrastructure which places critical constraints on cabling 1.3 Develop strategies to manage other infrastructure in relation to cabling 1.4 Notify appropriate personnel of safety hazards at the cabling work site
2. Manage remote power feed	2.1 Identify and avoid the risks posed by contact with remote power feeding services when performing cabling activity 2.2 Make site safe by identifying remote power feeding services which operate at above telecommunications network voltage (TNV) inside customer premises
3. Install cables and protective earth wires	3.1 Install cables according to manufacturer’s application specifications, including tension and bending stress requirements 3.2 Identify and avoid sources of possible damage to cable, including hot pipes, sharp edges and cable burn 3.3 Allow sufficient excess at cable ends to facilitate termination 3.4 Place and secure cable to maintain safety and interference segregation according to legislative and industry standards 3.5 Install cable fasteners with correct tension to prevent cable sheath damage or transmission impairment and trimmed flush to prevent risk of personal damage 3.6 Install underground cables to minimum depth of cover and segregation from hazardous electrical and other services according to current Australian Standards 3.7 Install underground cables excluding blown fibre tube systems to incorporate a blocking agent within the cable to prevent the ingress of water 3.8 Install aerial cables to minimum clearance, segregation from hazardous electrical and other services and minimum height requirements according to current Australian Standards 3.9Install over-voltage protection devices according to Australian Standards to all cable pairs, where required, to suppress voltage surges and protect from earth potential rise (EPR) hazards and protectively earth the devices 3.10 Protect earth wire insulation against damage and segregate protective earths according to relevant legislative and industry standards
4. Terminate and test cables and earth wires	4.1 Remove cable sheath to allow for correct termination length and without damage to underlying conductors and their insulation 4.2 Install Network Termination Device (NTD) modules according to manufacturer’s specifications and cable pairs neatly and sequentially fanned for termination 4.3 Terminate conductors according to recommended colour code sequence using appropriate termination tools in the manufacturer’s specified manner 4.4 Earth cable shield, if applicable, to manufacturer’s specifications, relevant industry codes of practice and Australian Standards 4.5 Conduct visual inspection to confirm termination colour code sequence has been followed prior to end-to-end testing of wire and pair termination integrity 4.6 Terminate earth wire according to industry accepted codes of practice and Australian Standards 4.7 Ensure earth wire continuity throughout and observe interface requirements with electrical systems 4.8 Test earthing installation for continuity, insulation resistance and conductive resistance according to accepted industry standards and Australian Standards 4.9 Confirm compatibility of alterations with existing systems and test new work both in isolation and when integrated with existing systems
5. Inspect cable route to ensure correct separations	5.1 Inspect separations along the entirety of the cable route and rectify separations which do not comply with regulations 5.2 Install barriers to achieve separations where sufficient spatial separation cannot be met
6. Create records	6.1 Provide the client with a job sign-off, telecommunications cabling advice form, at the completion of each cabling task 6.2 Complete NTD record cards for the work undertaken
7. Monitor work activity	7.1 Supervise cablers not holding appropriate registration for the task to ensure cabling activity is according to legislative requirements for safety and network integrity including the relevant Australian Standards

Foundation Skills

This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
