Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to safely install, maintain and modify the customer premises communications cabling required according to the 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

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.

Context of and specific resources for assessment	Assessment must ensure: a site on which communications cabling activities may be carried out use of cabling and field equipment currently used in industry licensing requirements and other site-related documentation.
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: direct observation of the candidate undertaking cabling installations and tests, and applying cable conductor identification codes oral or written questioning to assess knowledge of test results, standards requirements and specific technical procedures.
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICTCBL2137B Install, maintain and modify customer premises communications cabling: ACMA Open Rule.
