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.

Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
Elements describe the essential outcomes. |
Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Build and test direct current (DC) and alternating current (AC) circuits and telephone earthing |
1.1 Identify any hazards and work health and safety (WHS) issues for safe worksite and notify appropriate personnel 1.2 Connect series and parallel DC and AC circuit configuration following safe work practices 1.3 Choose appropriate test equipment and measure values of electrical quantities of circuits 1.4 Use calculations to verify measured values of electrical quantities in series and in parallel circuit configuration 1.5 Compare measured values to calculated values and determine reasons for any variations 1.6 Evaluate results and determine probable faults if relevant 1.7 Measure voltages present on telephone line and compare to exchange battery voltage 1.8 Measure resistance to earth, ensuring electrical earth in telecommunications installation |
2. Configure a safe ADSL circuit configuration with mode 3 connection |
2.1 Determine effects of bandwidth, frequency and attenuation on DSL circuits as used for broadband client access 2.2 Design and configure ADSL circuit from network boundary through to mode 3 socket for alarm system connected to monitoring station 2.3 Configure connection to ensure that ADSL circuit is not disconnected for safety reasons when alarm activation in conjunction with a mode 3 socket disconnects plain old telephone service (POTS) circuit 2.4 Use level 3 tester to verify correct termination and installation of digital transmission line |
3. Diagnose and rectify faults |
3.1 Determine urgency and impact of faults and required response timeframe for clearance 3.2 Identify type of fault and determine most probable causes of fault from data and historical trends where available 3.3 Select tools and test equipment relevant to system and type of fault 3.4 Diagnose fault in methodical and safe manner using suitable fault-finding technique 3.5 Isolate fault progressively to remove likely variables from diagnostic 3.6 Determine options to rectify fault and present to client for decision on rectification 3.7 Document test methods and results, and file with other system installation records |
4. Alter existing services |
4.1 Identify existing and proposed cable systems for altering services to existing installation 4.2 Plan alterations to cause minimal disruption to ongoing client activity 4.3 Use appropriate tools to safely terminate telecommunications cables and outlets 4.4 Identify and rectify any cable fault 4.5 Carry out alterations in safe manner and according to both mandatory and recommended industry standards 4.6 Identify risks posed by contact with remote power feeding services 4.7 Test alteration and obtain sign off with client |
