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.

Project Impact on Infrastructure

Early planning is required for all network changes. An explicit written statement must be obtained from the Manager, Communication Services advising any University infrastructure changes that may be necessary to support the project, and the corresponding costs.

The capital and current year maintenance costs must then be included in the project budget together with the costs associated with department systems. The costs may include equipment, contractors, staff and project management and inter or intra building cabling costs.

Project Managers must ensure that ongoing costs are clear, and that relevant departments are advised to consider the matter in their budgets.

The channel shall consist of Panduit cable, patch and drop cords and connecting hardware meeting or exceeding the Class E (Category 6) specification according to the AS 3080 standard. Pairs shall be terminated according to the EIA/TIA T568A wiring scheme as described in the AS 3080 standard.

Installation

Standard All Class E (Cat 6) structured cable systems shall be made using products, cable and installation practices that comply with the AS ACIF S009 and AS 3080 standards.

Testing All installed cables shall be tested to the AS/NZS 61935-1 Class E,

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.

Supplementary installation constraints

As a direct result of the critical nature of link and channel impedance compliance in a Class E (Cat 6) system, the following supplementary installation constraints are mandatory:



The maximum basic link length of 90metres shall be reduced by 0.4% per degree Celsius above an ambient of 20 Deg C. For LAN design purposes a maximum link length of 75m is strongly recommended.



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 E 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.

Wireless Local Area Networks (WLANS)

Specifications

Introduction The University operates a common Wireless Local Area Network called “UniWireless”. Other departmental or “private” wireless networks are not supported by Information Technology Services.

Departmentally funded additions to UniWireless can be arranged through Communication Services.

Wireless Spectrum

The portions of the wireless spectrum designated for Wireless Networks are considered a University wide resource. All devices that use the spectrum shall be approved by the Manager, Communication Services. Communication Services may require devices that cause interference to be switched off or reconfigured at its discretion.

Standards All local area wireless base stations shall conform to the 802.11a or 802.11bg standard. Use of base stations conforming to other standards such as 802.11n shall be subject to approval by the Manager, Communication Services.

Safety All wireless devices shall be compliant with Australian and International radiation standards.

Access Security & Authentication

All WLANs shall include a mechanism that blocks access to all but the following nominated groups: University staff, student, and honorary appointees. Departmental/Faculty WLANs shall provide users with a data encryption option. The selected data encryption option(s) shall be approved by Communication Services.

Connecting a Wireless Base Station to UniWireless

Departments wishing to connect a wireless base station to UniWireless may do so in only consultation with Communication Services. Departments shall acknowledge that Communication Services will configure, monitor and retain software control for each connected devices.

Departments additions to UniWireless are responsible for all costs associated with the purchase, site surveys, installation, licenses, Controller configuration, physical security and physical maintenance of all devices (within departmental spaces). This shall include two Class EA (Cat 6A shielded) cables per access point and associated costs required to connect the base station exclusively to a Communication Services managed switch.

(39)

Specifications,

Continued

Inline Power Wireless base stations shall be connected to inline power via UTP. The connection shall be clearly labelled with patch leads being purple sheathed.

WLAN Site

Survey A detailed pre and post site survey is required for each WLAN installation. Surveys need to document access point location, signal loss due to obstructions, the effect of neighbouring access points and other equipment. All of these need to be graphically represented. The survey should also document any installation considerations that need to be considered including heritage, antithetic considerations and other hazards.

Site Surveys are to be overlayed on University CAD diagrams.

Site surveys need shall be presented in their native electronic format. Result viewing software shall be made available upon request of the University. The University currently uses AirMagnet as its site survey tool – in locations where access points already exist or exist nearby – base line “project files” maybe available on request to Communication Services.

Pre site survey

“Pre site surveys” are required to plan each WLAN installation. This includes single or “hot spot” access point installations.

Pre site surveys shall be calibrated against coverage, density and usage requirements. AP power survey setting should not exceed 50mW.

Voice over Wireless

Voice over Wireless LAN installations shall only be considered with the permission of the Manager, Communication Services. Such installations require additional hardware, support and maintenance.
