Course Description

This unit applies to all contexts for indoor and outdoor installation within a customer premises and applies to both customer premises cabling and customer premises equipment. This unit applies to all communications applications whether digital or analogue including telephony, data, video including digital broadcasting, computer networks including LANs and WANs, and multi media. This unit may be applied to domestic, commercial or industrial installations. Assessment by a TITAB registered assessor is recommended. The six unit competency set ICTTC005D, ICTTC006D, ICTTC008D, ICTTC012D, ICTTC017D and ICTTC022D that meets the Australian Communications and Media Authority’s (ACMA) requirements for Cabling Provider Registration (CPR), is generally used as part of a more specialised customer cabling qualification. This set is usually regarded as more suitable for new entrants where limited industry experience has been obtained and forms the major part of specialised qualifications such as ICT20308 Certificate II in Telecommunications Cabling. When these six units are delivered as a set within state/territory funding approved programs, the two benchmark CPR units (ICTTC136C and ICTTC137C) are not required.
