    Guidelines1

    Important:  The NTG Project Management Office (DCIS) should be engaged at theearliest opportunity when considering projects that involve network infrastructure,particularly cabling. Specialist advice and direction can be provided in the design andconstruction phases of the project to ensure that the guidelines are followed, and that

    the project is delivered in accordance with the recommended standards andprocedures.

    1.1 Overview

    By way of comparison the following table displays the different cable Categories andthe recognised bandwidth for each of those Categories.

    ISO Equivalent Classifications ISO 11801:2002/Amd2:2010 

    Frequency

    Bandwidth 

    ISO (Components)  ISO (Cabling) 

    1 - 100 MHz  Category 5e  Class D 

    1 - 250 MHz  Category 6  Class E 

    1 - 500 MHz  Category 6A  Class EA 

    1 - 600 MHz  Category 7  Class F 

    1 - 1,000 MHz  Category 7A  Class FA 

    Category 5e Class D, Category 6 Class E, and Category 7 Class F, have beendiscounted for use by the NTG, and are not recommended for any NTG StructuredCabling Projects.

    In general terms, and dependent upon direction from the Project Manager, cablinginstalled for the NTG should be as follows:

      Category 6A Class EA UTP and F/UTP  – The minimum standard to be used formaintaining or upgrading existing structured cabling systems at NTG sites. Thedecision as to whether Cat 6A UTP or F/UTP will be used is to be made by the Agency,under advice from the Project Management Office.

    Cat 6A Class E A F/UTP (500MHz) is capable of supporting 10Gbps for up to amaximum of 100 metres. In simple terms at 10Gbps frequencies cabling is moresusceptible to “noise” due to Electromagnetic Interference (EMI) and cross talk(undesirable signals). “Noise” can result in multiple retries which can adversely affectapplications such as VOIP and Video Conferencing. Foiled UTP (F/UTP) reduces thesusceptibility of “noise”. 

    Shielded cable such as F/UTP is also regarded as more secure than unshielded (UTP) duethe ability of the shielding to reduce the possibility of electronic “sniffing”.  

    Typical life cycle is 10 years.

      F/UTP is recommended for larger sites.

  • 8/19/2019 Data Voice Cabling Specifications

    6/35

    ICT Data and Voice Cabling

    Department ofCorporate and Information Services  6

      UTP may be more economical for smaller sites where the possibility of EMI isnegligible and correct installation practises are followed.

      Category 7A Class FA (S/FTP)  – For Greenfield installations or upgrades toexisting Cat 7A cabled sites.

    Cat 7A Class FA is a fully screened and shielded cable, and is capable of frequenciesof up to 1200 MHz making it uniquely able to support all channels of CATV at 862MHz.

    Category 7A Class FA is currently rated for 10Gbps data transmission, and as a resultof the extremely high frequency possible with this class of cable, it is expected that thedata transmission rates will increase over time with hardware advancement. An interim40Gbps standard has been proposed.

     Another feature of the Cat 7 cabling system is the ability to use and manage individualpairs of the cable for different applications. Typically one Cat 7 100MHz workstationoutlet is equivalent to two cat 6 100MHz workstation outlets.

     Additionally, due to the unique ability of Cat 7A Class FA to carry up to four circuitsover one cable, the overall cost benefit between Cat 6A and Cat 7A Class FA is in theorder of 20%. Typical life cycle is 20 years.

    Shielded cable (STP – S/FTP) is regarded as being much more secure than unshielded(UTP) due the ability of the shielding to reduce the possibility of electronic “sniffing”. 

    Cat 7 S/FTP cabling is best terminated using a TERA style connector which makes useof shared pair technology allowing the cable to maximise use of all four pair in thecable. TERA style patch leads will be required to enable cross patching to EthernetSwitch ports and workstations Network Interface Cards.

      Laser optimised (OM4) Multi-Mode Optical Fibre - For Greenfield installations andupgrades to legacy sites.

    OM4 laser optimised multi-mode optical fibre is capable of supporting 10Gbps up to adistance of 550mtrs and is best suited in core backbone applications.

      Single -mode (OS2) Optical Fibre - For Greenfield installations and upgrades tolegacy sites.

    OS2 has a higher bandwidth than OM4 is capable of supporting 10Gbps up to adistance of 80Kms and is best suited for services a great distance apart.

      Where possible, wireless networking should be considered.

    Existing OM1 and OM2 multi-mode fibre is capable of 100Mbps to 1Gbps. OM1and OM2 Optical Fibre is not to be used for new NTG installations or upgrades.

    Specifications2

    This document describes the standards and practices to be followed in the supply,installation, documentation and testing of data and voice cabling technology used tosupport the data and voice communications services currently in use within theNorthern Territory Government (NTG).

    2.1 Introduction

    2.1.1 General Approach

    Note: For the purpose of this document, where an Australian, an Australian/NewZealand, or International standard is referred to, the intention is that the latestaddendum or edition, of that standard be used, i.e ISO/IEC 11801 2nd EditionAmendment 2:2010 will be referred to as ISO/IEC 11801 in this document.

    It will be the responsibility of the specification writers to establish the latest addendumor edition and include the complete reference to the relevant standard.

    Similarly, Category 6A Class EA UTP and 6A Class EA F/UTP may be referred to asCategory 6A, and Category 7A Class FA (S/FTP) may be referred to as Category 7A.

    Greenfield sites  are defined as buildings, sites or floors where the NTG has noexisting presence in regard to communications infrastructure (cabling, LAN or WAN)

    This specification covers the standard cabling requirements for the NTG Local AreaNetworks (and other services) utilising Category 6A and 7A shielded twisted pair, andmulti-mode optical fibre cables.

    Cat 7A is an emerging standard that may be selected for specific infrastructure

    upgrades and all Greenfield installations. All Category 7A cabling installations for theNTG must conform to ISO/IEC 11801.

    In general terms, and dependent upon direction from the Project Manager, cablinginstalled for the NTG should be as follows:

      Category 6A Class EA UTP or F/UTP – The minimum standard to be used. Thedecision as to whether Cat 6A UTP or F/UTP will be used will be made by the Agency,under advice from the Project Management Office. RJ45 connectors are used with Cat6A UTP and 6A F/UTP.

      Category 7A Class FA – (S/FTP) For Greenfield installations, or upgrades at specifiedsites which may have particular requirements. TERA style shared pair technologyconnectors are used with Cat 7A S/FTP.

      OM4 Multi-Mode Optical Fibre (MMF) - For Greenfield installations or upgrades atspecified sites.

      Single-Mode Optical Fibre (SMF) - For Greenfield installations or upgrades at veryspecific sites where distance is a factor.

    In all cases, installation of Cat 6, Cat 7, Multi-mode, and Single-mode optical fibre, shallmeet or exceed the national and international standards applicable to each type.

    2.1.3 Site Requirements

    Each site may have specific individual requirements, which may need a customisedsolution, however in most cases the layout of structured cabling within NTG owned orleased buildings will conform to a general standard.

    The DCIS Project Management Office is able to provide advice on site specificsolutions.

    Typically horizontal cabling to the desktop will be either Cat 6A or Cat 7A, and thevertical cabling will be OM4 multi-mode optic fibre.

    Existing Category 3 voice cabling may be re-used where suitable, however where abuilding is being fitted out or upgraded, voice services will be provided by the specifieddata cable.

    Usually each floor will have a Floor Distributor (communications room or server room),with an equipment rack or cabinet and patch panels for horizontal and vertical cabling.

    The horizontal cabling topology shall be in the form of a star, with the centre of the star

    being the Floor Distributor. For the larger sites multiple star configurations may beinterconnected in a tree of stars or meshed network.

    Department ofCorporate and Information Services  11

    2.2 General Requirements

    2.2.1 General

    The cabling system to be installed shall consist of horizontal cabling betweentelecommunication outlets in the work area and a patch panel mounted in an

    equipment room. In the case of data services where there is more than one equipmentroom and unless otherwise specified by the Project Manager, optical fibre will be usedfor backbone cabling between equipment rooms.

     All outlets and patch panel positions will be numbered, labelled and documented.Documentation will also include the results of the specified tests and a marked up floorplan showing outlet numbers and locations.

    The horizontal cabling system will be terminated at the Patch Rack and the appropriatepatch cables will be used to connect horizontal data services to active equipment orvoice ties.

    In the case of voice facilities where Cat 6A, or Cat 7A, is used to provide horizontalconnectivity, the patch cables will be used to connect horizontal cabling to voice tiesterminated on in the patch panels

    2.2.2 Communication and Equipment Rooms

    Every new or existing site where NTG staff are located who require ICT Infrastructure,including: cabling, LAN, WAN & Voice telephony will have a dedicated BuildingDistributor (Equipment Room), or a Floor Distributor (communications room) on eachfloor.

    Typically, small sites with less than 10 staff may only have a dedicated comms area

    with either a wall or floor mounted equipment cabinet. It is the NTG preference for allcabinets to be floor mounted where possible.

    Medium sized sites with less than 50 staff will have a dedicated Building Distributor(Equipment Room),, where all structured cabling, LAN & WAN equipment andtelephony infrastructure is to be located.

    Large sites with greater than 50 staff, may have requirement for multiple FloorDistributors (communications rooms), depending on the physical site characteristics egmultiple floors or buildings or horizontal distances greater than 80m within a building.

    Each dedicated Building Distributor, or Floor Distributor will have a separate air

    conditioning system in addition to any building air conditioning system. This separatesystem shall operate 24X7 and will ensure the NTG’s investment in ICT assets isprotected. The separate system should be on its own dedicated power circuit.

    The separate air conditioning system should ideally and where practicable, beconnected to a protected power supply eg on the building UPS or generator system.

    The air conditioning system shall be rated at a minimum of 20% larger than theanticipated power load for the equipment room. The Agency IT Manager will advise thepower loading for the communications equipment to be located in the room.

    Building Distributor and Floor Distributor rooms will have anti-static flooring and ideally

    have an advanced smoke detector system installed. All walls/roof are to be sealed with

  • 8/19/2019 Data Voice Cabling Specifications

    12/35

    ICT Data and Voice Cabling

    Department ofCorporate and Information Services  12

    paint or other sealant type substance that minimises cement or concrete dust beingintroduced to the room.

    Where Building Distributor and Floor Distributors have windows that are in directsunlight these windows are to be blacked out.

    Each Building Distributor and Floor Distributor will have a dedicated building earth

    cable installed in the room on an appropriately sized earth bar, to be determined inconsultation with the electrical engineer and the Agency IT Manager.

    The height of each room must be greater than the height of equipment cabinets eg2.2m.

    Building Distributor and Floor Distributor sizing is dependent on:

      the size of the site/staff;

      quantity of structured cabling;

      quantity of cabinets to be installed;

      quantity of ICT equipment to be installed; and

      any Agency specific ICT equipment e.g. BAS Servers.

    Refer to AS/NZS 3084 for guidelines on sizing.

     As an absolute minimum no communications room should be smaller than 1.8m x 2.2msquare. Refer to AS/NZS 3084

    2.2.3 Horizontal Cabling

    Each work area data communications outlet shall be cabled to the patch panel withoutany intermediate termination or jointing (unless the Project Manager specifies the useof consolidation points).

    Bridges, taps and splices are not to be used.

     All installed horizontal cable shall conform to the latest edition of AS/NZS 3080,ISO/IEC 11801.

    The cable to each work area data communications outlet shall consist of 4 twisted

    pairs.

    Existing cable requiring re-termination should be terminated using RJ45, or TERAstyle, connectors.

     A vertical duct shall be supplied and installed to carry cables from the ceiling space tothe equipment cabinet, where required for neat appearance and mechanical protectionof the cables. This duct shall have sufficient capacity for a 50% increase in the numberof cables.

     All horizontal cabling runs shall be provided with not less than 600mm of slack at eachend. Where cabling is run in ceilings, the slack shall be left in the ceiling space directly

    above the drop points. Where cabling is run within stud walls, the slack shall be left in

    13/35

    ICT Data and Voice Cabling

    Department ofCorporate and Information Services  13

    the cavity directly behind the faceplate. In all other cases, direction shall be obtainedfrom the nominated Technical Contact .

    Cable bends shall maintain the minimum bend radius specified by the manufacturer,but shall not be less than 25mm. Deformation of the cables (eg. pinching by cable ties,at points of support, when changing direction to pass through wall plates, etc.) shall becarefully avoided.

    Where cable deformation is found to have occurred, it will be the Contractorsresponsibility to replace affected cabling.

    Penetration through fire rated walls, ceilings or floors shall be stopped, or filled, usingapproved materials so as to maintain the existing fire rating.

    Installed cables shall not be under tension.

    2.2.4 Vertical Cabling Installation Practices

    Where cabling is required to be installed vertically, it shall be installed on Cable Traysand secured every 300mm using hook and loop fastening ties, such as Velcro® brandties. Take due care to not over tighten ties and place undue strain on the cablinginfrastructure.

    Where running parallel to power cabling, maintain a segregation of at least 300 mmand only cross at right angles.

    2.2.5 Work Area Telecommunication Outlets and Faceplates

    Unless otherwise stated each work area shall be provided with:

      A white faceplate, unless specified otherwise for a particular location(s);

      RJ-45, or TERA style, female connector

      The connector shall be designed so that the incorrect insertion of a plug is notpossible.

    Unless otherwise specified all outlet plates shall be mounted horizontally.

    Wherever possible, faceplates shall be flush mounted on walls or skirting duct.

    Faceplates mounted in walls shall be fitted with a protective cover to prevent ingress of
