1 Page 1 of 5 Title Demonstrate knowledge for telecommunications premises network cablers Level 2 Credits 2 Purpose This unit standard is for people installing and maintaining telecommunications cables on domestic, commercial, and industrial premises. People credited with this unit standard are able to: outline the basic concepts of telecommunications premises cabling; outline grounding, bonding, electrical protection, and circuit protection devices for telecommunications premises cabling systems; outline campus and building backbone systems and installation practices; outline horizontal cabling systems and termination practices; identify cables and associated hardware; outline fibre optic cables and installation practices; outline testing of copper, coaxial, and fibre cables; and outline the basic principles of fire stopping. Classification Telecommunications > Telecommunications - Service Delivery Available grade Achieved Guidance Information 1 The verb outline as used in this unit standard refers to a demonstration of elementary knowledge about the subject, in which the candidate states the important features or conveys the general idea of the topic referred to, without the need to provide technical reasons or the use of mathematics. 2 References AS/NZS 3084:2017 Telecommunications installations - Telecommunications pathways and spaces for commercial buildings; AS/NZS 3080:2013 Telecommunications installations - Generic cabling for commercial premises; AS/NZS :2004 Telecommunications installations - Basic requirements; AS/NZS ISO/IEC 15018:2005 Information technology - Generic cabling for homes; AS/NZS ISO/IEC :2012 Testing of balanced communication cabling in accordance with ISO/IEC Patch cords and work area cords; Electricity Safety Regulations 2010;
