Application

This unit describes the skills and knowledge required to safely install, maintain and modify customer premises communications cabling according to the Australian Communications and Media Authority (ACMA) ‘open’ Cabling Provider Rules for small installations connected to sockets, and larger commercial and industry installations involving many lines, multi-pair cables, backbone cabling, multi-story buildings and advanced termination modules and distributors.

It applies to individuals who provide services in telephony, carrier modems or multiplexers, private modems or data systems operating over a category one or two twisted pair metallic customer cable in a specific customer location. Individuals may install, maintain or modify new cable or upgrade cable capacity either, indoor, external, underground or aerial cabling on private and public property for an existing network or subsystem, or cabling infrastructure for convergence to next generation networks (NGNs).

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 ACMA accredited registrar.

Where aerial and underground cabling are used to supply services to the public, the specialist competencies as indicated in the ACMA Cabling Provider Rules – Pathways to cabling registration publication must be attained to undertake that work.

Pre-requisite Unit
