3 Communication Services - Networks Standards for the Installation of Telecommunication Networks Overview Introduction This document describes the Standards for the Installation of Telecommunication Network cabling that is to be installed or modified at the University of Melbourne. The objective of this document is to define a universal and structured communications cable plant infrastructure. The goal of such a cable plant is to accommodate all current and anticipated voice, video and data systems with little or no modification, thus reducing administration and maintenance resources. This document provides design consultants with detailed requirements and minimum standards for use in the construction or remodelling of buildings or facilities on Campus. It is expected these requirements and standards will be incorporated into project documents to ensure that the finished product meets the specific needs of the University. All cabling work within the University must comply with these standards in addition to any other relevant Australasian and International standards. Ownership The Information Technology Services division of The University of Melbourne is responsible for overseeing installation, maintenance and administration of all campus telecommunications and network critical physical infrastructure. This ensures that each building s infrastructure is planned to support adequate telecommunications rooms, ductwork, cabling and wiring within the buildings, and cabling between buildings to support The University s diverse requirements for voice, data and wireless To maintain a consistent structured wiring system throughout all University Campuses, the Communication Services section of Information Technology Services is the only entity authorized to approve new communication cabling, both inside and between buildings. Any proposed alteration to the cabling must be reported to Information Technology Services Communication Services for approval. Continued on next page Version July 2013 Page 4 of 54

All new structured cabling installations shall be implemented using Panduit Class EA (Cat 6A) Foil Shielded cable systems. Unshielded or partially shielded cabling systems shall not be used. All Class EA (Cat 6A) Foil Shielded structured cable systems shall be made using products, cable and installation practices that comply with the AS ACIF S009 and AS 3080 standards. All installed cables shall be tested to the AS/NZS Class EA, permanent link configuration. All marginal passes shall be treated as a failed test. Such tests shall be carried out using a Panduit approved Scanner with appropriate personality module. Result viewing software shall be made available upon request of the University. As a direct result of the critical nature of link and channel impedance compliance in a Class EA (Cat 6A) Foil Shielded system, the following supplementary installation constraints are mandatory: Structured cabling systems shall comprise certifiable cable and connectors from Panduit. This requirement is based on interoperability and warranty considerations. Catenary wires shall only be used to support Class EA cables in ceiling or under-floor areas in cases where it is agreed with Communication Services and that no other alternative can be used. Cables run through such areas shall be laid up on galvanized steel tray or housed in PVC duct, conduit or flexible hose. A change of plane (e.g. from the vertical to the horizontal) in a tray installation shall be accomplished through the use of sections of waterfall. The same shall apply to locations where bunches of cables exit the main route and leave the tray. Nylon cable ties shall not be used to bunch or secure a cable or cables. All bunching and securing shall be accomplished with velcro style strips. Cable slack at the Floor Distributor cabling hub location shall be laid up in a Flaked figure-of-eight configuration and supported and secured with Hook and Loop type strips suspended in the vertical plane by Velcro strips.
