Application
This unit describes the skills and knowledge required to install telecommunications earthing system to metallic frames, utilised for telecommunications systems that include digital and analog, telephony, data, video, digital broadcasting, computer networks, local area networks (LANs), wide area networks (WANs) and multimedia.
It applies to telecommunications technicians and field officers who install indoor or outdoor earthing systems for domestic, small office home office (SOHO), commercial or industrial multi-storey and multi-site locations within customer premises.
Licensing, legislative, regulatory and certification requirements apply to telecommunications earthing 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.
