Design infrastructure for telecommunications network installations


Application

This unit describes the skills and knowledge required to design supporting infrastructure for telecommunications network installations; for carrier grade switching, transmission and access equipment and associated media, power and monitoring equipment and alarm systems, fibre distribution hubs (FDHs), and remote power feeds.

It applies to field officers, design technicians or technical supervisors from carriers, contractors or other service providers working with switching, transmission and radio networks and the various transmission paths including cable, optical fibre, radio, microwave and satellite.

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.

Evidence of Performance

Evidence of ability to:

determine potential earthing locations, cable routes, cables trays, data cabinets, telecommunication enclosures, distributors

design metal superstructure

design protective earth and functional earth installations

design power infrastructure

design, monitor and rectify faults in DC power distribution

design locations and facilities for access network infrastructure.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.


Evidence of Knowledge

To complete the unit requirements safely and effectively, the individual must:

evaluate capabilities and performance of cabling types, connectors and cabling structures for given design parameters

explore common carrier telecommunications applications and related equipment and infrastructure suited to a design

determine the most appropriate connections to carrier infrastructure or equipment

identify and recognise compliance requirements of current legislation relating to installation of telecommunications equipment and connection to carrier services

evaluate environmental impacts including options for green information and communications technology (ICT) installations for network topologies, interfaces and interconnect solutions

define work health and safety (WHS) requirements for the design to ensure a safe installation plan including:

confined spaces

electrical safety

working at heights

manual handling and lifting

materials handling

physical hazards

evaluate and summarise network and transmission supplies and equipment required for a design

determine power requirements and electrical safety for a specific design

specify warranty information for equipment supplies and contractor work guarantees

devise an appropriate survey to determine design criteria for a given site

explore and evaluate the nature of tools and equipment required for installation of the design

consider power distribution work requirements and the impact on the design.


Assessment Conditions

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 networks engineering field of work and include access to:

special purpose tools, equipment and materials

site where installation of supporting infrastructure may be conducted

plant, tools and equipment currently used in industry

relevant regulatory and equipment documentation that impact work activities.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
