Unit Descriptor
Unit descriptor |
This unit describes the performance outcomes, skills and knowledge required to safely install, maintain and modify customer premises communications cabling required according to Australian Communications and Media Authority's (ACMA) 'Restricted' Cabling Provider Rule. Restricted cabling is used in typical domestic premises, small offices, home offices and small business premises. Restricted cablers can install cable in large commercial and industrial premises provided the cabling is behind a compliant device and is not via jumperable distributors or patch panels. The telecommunications Cabling Provider Rules (CPRs) 2000 place various limitations on Restricted cablers. These include a prohibition on them performing cabling work where they may have access to a reticulated electrical supply that exceeds typical domestic single-phase and three-phase electrical supply voltages - nominally 240 volts AC (for single phase) or 415 volts AC (for three-phase). Assessment by a TITAB registered assessor is recommended. 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. |
Application of the Unit
Application of the unit |
This unit applies to customer cabling terminated on sockets and network termination devices (NTD). It applies to the installation, maintenance and modification of indoor and external cabling. Customer cabling, for the purpose of the 'Restricted' Cabling Provider Rule, may be used to connect devices for a range of applications including telecommunications, simple data and computer use, security alarm panels and fire control panels. Cabling may be metallic or optical fibre and may be aerial or underground. The cabling task may be a new cable installation or upgrade of cable capacity for an existing network or subsystem for convergence to Next Generation Networks (NGN) applications. The cabling installer may provide services in telephony, voice over internet protocol (VoIP), internet protocol TV (IPTV) and computer data over a single metallic customer cable or optical fibre cable in a specific customer location. |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Work within the constraints imposed by customer premises and ACMA regulatory environment |
1.1. Prepare for restricted cabling work within the regulatory environment , cabling environment , cable type , cable identification , termination systems , earthing and protection , records and 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 ties 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 AS/ACIF S009:200 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 AS/ACIF S009:2006 3.9. Install over-voltage protection devices according to AS/ACIF S009:2006 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 NTD terminating 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 AS/ACIF S009:2006 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 wires with connectors recommended by manufacturers according to accepted industry codes of practice and AS/ACIF S009:2006 4.7. Maintain 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 including AS/ACIF S009:2006 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 AS/ACIF S008:2006 and AS/ACIF S009:2006 |

|
Method of assessment |
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
Aboriginal people and other people from a non-English speaking background may have second language issues. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed. In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. Where applicable, physical resources should include equipment modified for people with special needs. |
