Description
Employability Skills
Learning Outcomes and Application This unit describes the skills and knowledge required to practice safe installation, alteration and configuration of the carrier network termination device/asymmetric digital subscriber line (NTD/ADSL) filter and modem/mode 3 socket/cabling, for an alarm system connected to a monitoring station using a carrier line supporting an ADSL modem service, used for Open and Restricted Cabling Registration.It applies to cablers, installers and technicians working in the field of installation, maintenance or upgrades of existing systems in voice, data or security systems, and in the context of technology convergence and digital subscriber line (DSL) technologies as applied in the telecommunications industry.Work functions in the occupational areas where this unit may be used are subject to regulatory requirements. Refer to the ICT Implementation Guide Companion Volume or the relevant regulator for details of licensing, legislative or certification requirements.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – cabling field of work and include access to:

special purpose tools, equipment and materials
