Description
This unit describes the skills and knowledge required for fault-finding and testing for the presence of an operational subscriber line at network termination devices (NTDs). These lines are crucial in connecting customer equipment to the carrier for the purposes of providing telephony and internet protocol (IP) data services. These network providers use convergent technologies to deliver services of next generation networks (NGNs).It applies to technicians and cable installers who install and maintain IP-based equipment for customer and service providers for services, such as internet protocol TV (IPTV), IP security, digital home networks, IP-based cable access, TV (CATV), IP core and access networks, home automation, interactive TV, smart grids and cloud computingAustralian Communications and Media Authority (ACMA) cabling registration applies to maintaining or installing new cable elements.Refer to the ICT Information and Communications Technology Companion Volume Implementation Guide or the relevant regulator for details of licensing, legislative or certification requirements.
Notes
Elements and Performance Criteria
1. Plan to locate and rectify basic faults
  • 1.1 Arrange site access according to enterprise procedures and customer requirements
  • 1.2 Obtain information from customer about nature of the fault
  • 1.3 Obtain suitable tools and test equipment
  • 1.4 Obtain appropriate personal protective equipment (PPE)
  • 1.5. Identify requirements for basic identification and fault-finding of cabling from network termination device (NTD) to customer equipment and seek assistance as required
2. Identify and confirm customer and NTD equipment in place
  • 2.1 Identify type of NTD used and its application to satellite, fibre, fixed radio, hybrid fibre coaxial (HFC) or digital subscriber line (DSL) telecommunications network/s
  • 2.2 Identify and document typical equipment connected to NTD
  • 2.3 Confirm correct equipment is being used for installed NTD
3. Identify and inspect NTD and customer equipment cables and patch cords
  • 3.1 Check that NTD equipment and customer equipment are interconnected utilising cables and patch cords
  • 3.2 Ensure all cabling sockets are visually intact and undamaged
  • 3.3 Ensure all patch cords are visually intact and undamaged
  • 3.4 Complete wire mapping to ensure new work is completed correctly and is in good working order
  • 3.5 Ensure all cable, patch cords and cabling products are of the same signal bandwidth category
  • 3.6 Obtain NTD and customer equipment user guides
  • 3.7 Utilise NTD and customer equipment user guides to determine correct light-emitting diode (LED) status that indicates the equipment is operating correctly
  • 3.8 Identify and record visual status of all customer equipment and NTD equipment prior to any investigative process
4. Repair faults found in NTD and customer equipment
  • 4.1 Follow appropriate user guide fault tables to remedy equipment status according to equipment manufacturer guidelines
  • 4.2 Conduct basic fault-finding using methodical and safe practices suitable for system and problem type
  • 4.3 Ensure cabling or patch cord elements are correctly terminated utilising wire mapping testers according to industry standards
  • 4.4 Correct faulty cabling by re-terminating sockets, replacing sockets and re-terminating cable or replacing damaged cable elements
  • 4.5 Correct faulty patch cords by re-terminating plugs or replacing with new patch cords
  • 4.6 Power down equipment for 30 seconds and reboot equipment as a remedy to problem/s
  • 4.7 Report failure of equipment to obtain normal working status to customer/supervisor and/or NTD owner for a determination to replace faulty equipment or to have equipment repaired
  • 4.8 Ensure test equipment power adaptors are providing correct voltage to equipment, using an appropriate test device, and replace power adaptors as required
  • 4.9 Ensure NTD equipment and customer equipment is communicating with internet by exploring internet with a computer browser gaining correct page displays from a website
  • 4.10 Ensure customer device is connected to a wi-fi modem using service set identifier (SSID) and password
5. Complete documentation and clean-up worksite
  • 5.1 Advise customer of successful fault clearance and obtain sign-off for customer agreement once fault is resolved and for invoicing purposes
  • 5.2 Complete all records as required
  • 5.3 Complete reports to justify fault diagnosis and rectification methodology as required
  • 5.4 Remove all waste and debris from worksite and dispose of according to environmental requirements
  • 5.5 Restore changes made to worksite during fault repair, according to industry standards
