7 1.0 Introduction 1.1 Overview The aim of this document is to provide a cabling infrastructure which has high reliability, is easy to maintain and can support the applications and services of today and the future. The specification has been written to ensure that a cost-effective solution is provided without compromising any standards or safety issues, and that all single points of failure are designed out by means of route diversity and service duplication. This document describes the specification for the design of the network infrastructure of both fibre and copper networks for both voice and data services into and out of single and multiple building(s), and all interconnections between buildings. It is important to note that all telecom rooms are for the sole occupancy of COMPUTING SERVICES and their associated voice and data distribution equipment. It is not permissible for other parties to store or install equipment within these rooms. The product set has been standardised on TE Connectivity. This product set has been selected for its high degree of reliability, quality and performance. By standardising on the TE Connectivity product set a standard warranty for voice and data has been set for all buildings within the University of Bath. To this effect TE Connectivity voice and data products specified within this document must be selected. All installation work must be covered by a TE Connectivity warranty. To ensure that this happens only approved TE Connectivity Premier and Authorised Integrators can be used. 1.2 Specification of Criteria Two levels of criteria are specified, mandatory and highly desirable. The mandatory requirements are described by the word must and shall ; whilst highly desirable are described by the words should, may or desirable. Mandatory requirements must be adhered to under all circumstances and may not be changed. Highly desirable requirements are the desired ways of design, implementation and documentation that may be changed depending on individual circumstances. All parties shall adhere to this specification document. Any deviation from this document must be on written approval by Computing Services.

8 1.3 Building Design Each item of a buildings cable infrastructure can be broken down into three constitute subsystems: campus distribution (CD), building distribution (BD) and floor distribution (FD). Figure 1 Building block diagram

9 2.0 Definition of Terms 2.1 Overview To provide detailed information regarding the definitions of terms that are pertinent to this standard. 2.2 Definition of Terms Building A roofed structure enclosed by walls on all sides, used for the express purpose of housing telecommunications related equipment for the transmission and reception of data, voice, video etc, signals and any related processing of the signal content Backbone cable A cable that connects any combination of carrier and network devices for the transmission of multiplexed signals Channel ISO/IEC 11801:2002 (2002:p20) defines a channel as The end to end transmission path connecting any two pieces of application specific equipment. Equipment and work area cords are included in the channel, but not the connecting hardware into the application specific equipment Consolidation point ISO/IEC 11801:2002 (2002:p20) defines a consolidation point as A connection point in the horizontal cabling subsystem between a floor distributor and a telecommunication outlet CP cable ISO/IEC 11801:2002 (2002:p20) defines a CP cable as A cable connecting the consolidation point to the telecommunications outlet(s) CP link ISO/IEC 11801:2002 (2002:p20) defines a CP link as The part of the permanent link between the floor distributor and the consolidation point, including the connecting hardware at each end Cross connect ISO/IEC 11801:2002 (2002:p20) defines a cross connect as An apparatus enabling the termination of cable elements and their cross-connection, primarily by means of patch cords or jumpers. Incoming and outgoing cables are terminated at fixed points Distribution Equipment Room (DER) A room within a building or building that houses all the core network transmission and processing equipment as well as the campus backbone infrastructure Entrance room A room within the building that caters for the entry of cables into the building Pit A box, joint box, manhole or cable chamber Pit cover A covering lid used to seal a pit.

12 3.0 Cabling Systems 3.1 Overview The topology of the cabling systems shall be set out and clearly defined in terms of design and product set. 3.2 Cabling System Structure The cabling system can be considered as a series of clearly defined subsystems, each one interconnecting a specific piece of active equipment that may in some cases change the media type. Figure 2 Building system diagram It can be seen that there is a maximum of three hierarchical cabling systems for any one end to end solution. The basic elements are as follows:

13 Campus Backbone (Blue) Building Backbone (Orange) Horizontal (Green) Campus backbone cabling subsystem The campus backbone is the cabling system that provides data and/or telecommunication services between buildings. It connects two or more BD s. It may be in the form of either fibre or (for remote sites only) a suitable WAN technology may be employed Building backbone cabling subsystem The building backbone is the cabling system that provides data and/or telecommunication services between areas/floors within a building. The building backbone must be fibre and Cat6a. The building backbone is necessary due to the distance limitations in providing services to the desk from a single location. In this respect it is only usually necessary in larger or multi-storey buildings. It connects the BD to the FD(s) Horizontal cabling subsystem The horizontal cabling is the cabling system that provides data and/or telecommunication services from the FD to the user outlets (TOs). It may be in the form of copper, fibre and wireless.

14 4.0 Telecommunications Room 4.1 Overview A telecom room is a generic term used to describe entrance, equipment and main communication rooms. This section details the design criteria for all types of telecom room and their association with each other. Consideration of the telecoms room is fundamental to all other aspects of the building design. It is critical that the telecoms room is designed correctly and consideration given to: Position Space Layout Lighting Ventilation Power Security Routing False floor Ceiling void Cable management 4.2 Position General The telecoms room must be positioned with consideration to other telecoms rooms and the floor outlets that it will distribute to. The most important rule is to plan the position of the room to cater for the maximum distances for telecommunication outlets (TOs). IMPORTANT: the use of the term telecom room covers all types of room that house telecommunication equipment and distribution cabling i.e. Distribution Equipment Room (DER), Main Equipment Room (MER) and Satellite Equipment Room (SER) Telecom Room Position in Respect to TOs and Backbone Cabling DER Design A data room that provides fibre connectivity to other buildings within the campus is known as a Distribution Equipment Room (DER). A DER will house the CD and may in some instances also house a BD and FD. However the primary function of the MER is to provide core switching to other buildings. Distribution Equipment Rooms (DER): Should ideally house external campus duct entry points If campus duct entry points are not within the DER then they must be located as close as feasible Where the campus duct entry points are not within the DER the containment runs must be capable of accommodating multiple high core/pair cable and multiple 12 way blown fibre tube assemblies Have a minimum of two different campus duct entry points

15 Have a minimum of two different carrier trunk feeds Each carrier feed must be capable of servicing the load of the other carrier in the event of a trunk failure Carrier trunks must not share the same building entry duct Carrier trunks must not share the same route Figure 3 DER design Single MER Design A telecom room that is linked to the DER via fibre and copper and provides copper connectivity to TOs within a building is known as a Main Equipment Room (MER). A MER will house the CD and FD and where there are multiple telecom rooms within a building will also house a BD. All buildings must have a minimum of one MER. A telecom room that is linked to the MER via fibre and provides copper connectivity to TOs within a building is known as a Satellite Equipment Room (SER). A SER will house the BD and FD. If one telecom room can house the CD, BD, FD and service all end user devices whilst maintaining the 90m rule then a single MER may be used. A single MER must: Be central to the building Have a minimum of two different physical routes to feed the DER Each DER feed must be capable of servicing the load of the other DER in the event of a trunk failure DER trunks must not share the same building entry DER trunks must not share the same route All TO channel lengths must maintain the 90m rule

16 Figure 4 Single MER design Multiple Data Room Design A single data room would be preferred, where a single data room cannot be achieved then multiple telecom rooms must be used. When using multiple telecom rooms they must be situated to cater for the 90m horizontal cabling rule. Under this design criterion the telecom room housing the CD, BD and FD would be classified as a MER. The telecom room(s) housing only a FD would be classified as a SER. The MER must: Be separated as far as possible from the SER whilst maintaining the 90m rule Have a minimum of two different DER feeds Each DER feed must be capable of servicing the load of the other DER in the event of a trunk failure DER trunks must not share the same building entry DER trunks must not share the same route All TO channel lengths must maintain the 90m rule The SER must: Be linked to the MER with two resilient fibre feeds Be linked to the MER with a minimum of 8 Cat 6a F/FTP channels The resilient fibre feeds must not share the same route All TO channel lengths must maintain the 90m rule

17 Figure 5 Multiple telecom room design Multiple MER Data Room Design Buildings with multiple telecom rooms that are classified as critical importance must be designed with two MERs and where necessary additional SERs. The MERs must: Be separated as far as possible from the SER whilst maintaining the 90m rule Be separated as far as possible from each other Be linked together with a single fibre feed Have a single DER feed into each MER Each DER feed must be capable of servicing the load of the other DER in the event of a trunk failure DER trunks must not share the same building entry DER trunks must not share the same route All TO channel lengths must maintain the 90m rule The SER(s) must: Be linked to each MER with a single fibre feed Be linked to each MER with a minimum of 8 Cat 6a F/FTP channels The resilient fibre feeds must not share the same route All TO channel lengths must maintain the 90m rule

18 Figure 6 Multiple MER room design Multiple Floor Data Room Design Where the building contains multiple floors then a minimum of 1 data room must be provided for every 3 floors. Figure 7 details a multiple floor data room design.

19 Figure 7 Multiple floor telecom room design Siting Telecom Rooms Site the room to avoid areas that may limit any future expansion e.g. siting a telecom room next to areas containing heavy plant, lifts or other such equipment. In areas where flooding is a potential threat all telecom rooms must be sited one floor above the maximum flood level. In multi-storey buildings that can be serviced by a single main communications room it should be located central to the building. This is dependent on the building design and the rules of this document. In a multi-storey building that requires one or more main telecom rooms and one or more equipment rooms the main telecom rooms should be on the lower most floor. All other rooms must be distributed as according to this document.

20 Where security is a concern the telecom room, where possible, must not be sited against external walls. Basement floors are desirable followed by floors above the ground floor. The telecom room must be located away from high-level sources of EMI. The telecom room must be sited with its own access from a major thoroughfare. Telecoms room must not be sited within a plant room, or off an office, laboratory or other occupied space. Larger buildings should have their telecom rooms positioned adjacent to main ICT risers on each floor No wet services or liquid to run through or above telecom rooms. Mechanical risers must not be located near telecom rooms. 4.3 Size of Telecom Room The telecom room shall be designed to accommodate all the known and planned requirements for the equipment it shall house. The room shall be designed to accommodate all floor areas that are to be used as office areas, or could accommodate office areas. Calculation of floor space is dependent on the purpose of the telecom room. All calculations shall be based on an interconnect channel design. Interconnect with Switches A design where the telecom room only houses switches and patch panels. The switches patch directly into the distribution patch panel. For all other types of telecom room general rules can be applied. It must be noted that these rules only apply as a minimum as the room must meet the requirements of the Authority and the telecommunication design for the building.

21 4.4 Telecom Room Layout The following are examples of requirements. The layouts do not change between the general office, residential and student learning. All designs shall be based on an interconnect model with access layer switches only Channels Figure Telecom room layout The switches and the structured wiring patch panels are housed in a single 47U open frame. If using 48 port 1U switches and 24 port 1U patch panels then the cabinet utilisation is as follows:

Wireless APs may be installed within the suspended ceiling void or below the ceiling void. Where an AP is installed below the suspended ceiling void a further lockable outlet must be installed i.e. the suspended ceiling outlets will now act as a CP point. If the RJ45 interface to the equipment is accessible to multiple parties a lockable cat 6a patch lead must be used. The patch lead must be lockable at one end only as the other end plugs into the lockable outlet. There must be a minimum of a double cat 6a outlet for every 100m 2 of floor space.

The Vendor must seek approval in writing from the University for the specification of the barrier system, communications and position. 5.7 Cable Management Cable management is split between cable tray/basket and trunking. This is primarily to cater for the differing requirements for capacity and future expansion requirements Trunking Trunking for the use of telecommunication services should be dedicated to telecommunication services only. Where multi-compartment trunking is used the telecom services compartment must not be shared with other services. When using triple compartment dado trunking, all communication cabling MUST only use the top and bottom sections of trunking.

53 When calculating the capacity of trunking it must have at least 30% future capacity. This is calculated above the requirements for having the building flood wired. All trunking shall be calculated to cater for category 6a cable, regardless of what is installed on day one. Allow 7.4mm for the overall diameter of a category 6a cable. Example 1 a 65 x 70 piece of trunking Area of one cable = = 2 (cable diameter) x (7.4) 2 x = 42.99mm 2 Useable area of trunking = (width x depth) x 0.7 = (70 x 65) x 0.7 = 3185mm Number of cables = = useable area of trunking area of one cable x x 2 = 37 For standard trunking sizes table 5.2 details the maximum cable capacity. These are calculated for category 6a cables. When using mini trunking there is no consideration for future capacity i.e. it is allowable to 100% fill during the initial installation. The only exception to this rule is if there is a known future requirement for further cables to be installed in which case the trunking size must be selected to cater for the future requirements.

54 5.7.2 Cable Tray Cable tray/basket for the use of telecommunication services must be dedicated to telecommunication services only. The cable tray/basket must not be shared with other services. When calculating the capacity of cable tray it must have at least 30% future capacity. This is calculated above the requirements for having the building flood wired. All cable trays shall be calculated to cater for category 6a cable. The maximum depth of cables on a cable tray is 100mm. Allow 7.4mm for the overall diameter of a category 6a cable. Example 1 a 300mm cable basket with a depth of 150mm Area of one cable = = 2 (cable diameter) x (7.1) 2 x = 39.6mm 2 Useable area of basket = (width x depth) x 0.75 = (300 x 150) x 0.75 = 33750mm Number of cables = = useable area of trunking area of one cable x x 2 = Cable Capacity Planning of cable capacity must be co-ordinated with all parties involved in the planning, design and implementation of the IT network. The capacity of cables must cater for requirements that will be implemented from day one and all known requirements that will follow in the future plus a 30% additional capacity for unknown future expansion. 5.9 Internal Cable Tray There must be no breaks between any two sections of floor containment. Where the containment meets the riser containment there must be no break in continuity. Where cables must penetrate walls or fire barriers the containment must penetrate completely through. It is not acceptable to drill holes to allow cables to pass between walls or fire barriers and butt up the containment. Where fire barriers are encountered the cables and containment must be sealed to the fire rating of the penetrated barrier for heat, fire and where permissible smoke.

55 All 90 0 bends, T sections and X sections must be manufactured products by the same manufacturer as the cable tray or basket. It is not acceptable to make any of these sections from straight sections of cable tray or basket. There shall be separate trays for power and telecommunication services. Where the trays cross they must be bridged and cross at The routes shall be planned to provide a matrix of cable tray that allows diverse routing to the telecommunication outlets (TOs). This shall provide an A and B route for the cables. Where there are multiple tiers of cable trays then the most accessible tray must be reserved for structured wiring i.e. if there are three tiered cable trays within a suspended ceiling then the bottom tray must be reserved for structured wiring. The cable tray must be colour coded. Every 5m and at each change in direction of the cable tray access hatches must be provided in sealed suspended ceilings. The access hatch must have a square aperture of 550 x 550mm Suspended Floor All cables within suspended floor voids must be laid on cable trays to a depth of no more than 150mm. The trays must be mounted off the floor on standoff brackets to protect the cables against possible floods/spillage of liquid. The minimum height from the top of a cable bundle to the underside of the false floor shall not be less than 50mm. The minimum height from the underside of the tray to the finished surface of the floor is 50mm. Figure 37 Suspended floor cable tray Suspended Ceiling All cables within suspended ceiling voids must be laid on cable trays to a depth of no more than 150mm. Lighting and sprinkler systems must not be impeded by tray work.

56 The minimum height from the top of a cable bundle to the underside of the ceiling shall not be less than 75mm. The minimum height from the underside of the cable tray to the underside of the ceiling tile shall not be less than 75mm. Figure 38 Suspended ceiling cable tray 5.10 Patch Cord Colours and Category Patch cord colours shall be selected to match the service to be provided. The colours and services are: Voice Red Data - Grey All patch leads shall be category Cat6a and 2mt unless specified by Computing Services. All patch cables to be supplied by contractor and be numbered on both ends with socket numbers.

57 6.0 Backbone Distribution 6.1 Overview The backbone distribution is split into two areas, namely the Campus Distribution (CD) and the Building Distribution (BD) backbone. The CD links buildings together whilst the BD links telecom rooms within buildings. The Campus Backbone distribution extends from the CD within the main telecom room and any subsequent CDs in other buildings. The building backbone distribution extends from the BD within the main telecom room to the FD(s). It is critical that the backbone distribution is designed correctly and consideration given to: Data communications media choice Layouts Routing False floor Ceiling void Cable management 6.2 Media Choice OS2 All new CD fibre links must be blown fibre OS2, regardless of whether the building has traditional fibre that is not being refreshed. For new buildings or buildings that will be refurbished/refreshed the BD fibre cable must be blown fibre OS2. For existing buildings that have BD traditional fibre already installed and there is an additional requirement for new BD links then the fibre cable must be blown fibre OS2. For temporary CD and BD links traditional tight buffered cable may be used. The grade of the fibre cable will be dependent on the type of service required. All fibre cores must be terminated on LC duplex pigtails by fusion splicing. It is not acceptable to use mechanical splicing techniques Cat 6a All BD links must be cat 6a shielded. The cable selection must be F/FTP cat 6a. 6.3 Fibre Design The two options for the fibre design infrastructure are a building with two main equipment rooms and a building with a single main equipment room Desirable Single Main Equipment Room Where feasible, a building containing a single MER must have two diverse routes, each route must emanate from a different distribution building. Each feed shall be a 8 core OS2 fibre cable. Each 8 core OS2 fibre cable must be installed into a different drawer of a 1U split fibre patch panel within the MER. The MER CD links must be in a separate patch panel to the MER CD links.

58 A blown fibre ring shall be installed around the campus and two blown fibre tubes shall be cut and jointed onto two off 4 way direct install tube units to provide the A leg and B leg feeds. It is important to note that the 4 way blown fibre feeds into the building must not share the same access chamber or duct. Each SER shall have two feeds from the MER. Each feed shall be a diversely routed single 8 core OS2 fibre cable installed in a dedicated 4 way LSOH blown fibre tube unit. Each 8 core OS2 fibre cable must be installed into a different drawer of a 1U split fibre patch panel within the MER and SER(s) i.e. the top drawer is reserved for A leg links and the bottom drawer for B leg links. Where there are multiple SERs they may share the same patch panel within the MER.

Where diverse routing cannot be achieved agreement of the routing must be obtained from COMPUTING SERVICES. A blown fibre ring shall be installed around the campus and two blown fibre tubes shall be cut and jointed onto a 4 way direct install tube unit. Two off 8 core OS2 cables shall be blown in from two different DERs. Each 8 core OS2 fibre cable must be installed into a different drawer of a 1U split fibre patch panel within the MER. The MER CD links must be in a separate patch panel to the MER CD links. Each SER shall have two feeds from the MER. Each feed shall be a diversely routed single 8 core OS2 fibre cable installed in a dedicated 4 way LSOH blown fibre tube unit. Each 8 core OS2 fibre cable must be installed into a different drawer of a 1U split fibre patch panel within the MER and SER(s) i.e. the top drawer is reserved for A leg links and the bottom drawer for B leg links.

63 Figure 45 Desirable blown fibre joint arrangement Where a building needs a feed from the blown fibre campus ring the ring shall be broken into at the two diverse access chambers. The same tube shall be cut in both the chambers i.e. if tube 2 is cut in the chamber that will provide the A leg then tube 2 must also be cut in the chamber that feeds the B leg. The cut tube that now links chamber A and B must be capped off with an external end blocking cap. The A leg tube must be jointed onto the first 4 way blown fibre building feed and the B leg feed must be jointed onto the second 4 way blown fibre building feed. All tubes that are not to be used in the two off 4 way building feeds must be capped off with external end blocking caps Acceptable Joint Arrangement Where a building needs a feed from the blown fibre campus ring the ring shall be broken into at the single access chamber. The required tube shall be cut. The A and B leg tube must be jointed onto the 4 way blown fibre building feed. All tubes that are not to be used in the 4 way building feed must be capped of with external end blocking caps.

Where British Standards are quoted the current published issue is to be complied with. Where equivalent European Standards exist, they must be adhered to insofar as they are deemed to apply. External ducting from two distribution buildings to the new building is the responsibility of Estates and Facilities or the building project. External duct feeds into the building must be capable of accommodating all services into the building. It is not acceptable to use aerial cables as primary or secondary feeds into buildings. Cables containing high or lowtension voltages must not be installed in telecom ducts.

66 Two off 100mm twin walled duct must be installed for fibre cables and telecom cables. Where possible each duct shall enter the building at separate locations to provide resilience. Cables must not be direct buried but must be installed within a ducting system. Ducting quantities must be calculated on the maximum known requirement and future requirements with an additional 40% capacity for unseen requirements. The figure below are for the absolute minimum requirements and do not take precedence over the above statement Ducting Capacity Each duct shall not be filled to more than 60% capacity. Duct size shall be calculated on the services required plus an additional 50% extra for future services. The additional 50% shall be calculated on the usable area Duct Construction The duct must be of a twin wall construction and manufactured from HDPE. The colour coding used shall be green Routing For campus environments containing 2 or more buildings there must be resilience whereby the building is fed from two diverse routes. Each diverse route must be fed from a different building Building Entry In existing buildings an aperture will be made in the building fabric by core drilling or other vibration free means. Any aperture will allow for a minimum of 25mm of resin mortar to be applied around the entire circumference of any duct. The surface of any aperture created by core drilling will be roughened to give a good bonding surface for the resin mortar. In buildings that have less than 1.5m of headroom below finished floor level, the lead-in ducts shall be brought into the building from below. The ducts will terminate flush with the slab level and will be sited as close as possible to the wall of the building. Bends having a minimum radius of 900mm may be used to achieve this lead-in. In buildings that have greater than 1.5 of headroom below finished floor level the lead-in ducts may be brought into the building horizontally through a wall. The distance between the lowermost duct and the slab will not be less than 600mm. There shall be created a bond between the outside of any lead-in duct and the fabric of the structure. To effect this bond that part of the lead-in ducts that will be contained within the wall shall be cleaned thoroughly with methylated spirit or isopropyl alcohol and the following treatment applied: Treated all round the circumference for a minimum length of 300mm with suitable solvent weld cement Before this cement dries a compound mixture of 3:1 dry sand to cement will be applied to the treated area or an approved bitumastic compound applied all around the circumference for a minimum length of 300mm The complete circumference of the ducts will be coated The space around ducts will be filled with a Resin Mortar flush to existing surfaces Lead-in ducts will be finished with the mouth of the duct collar flush with surface of the wall. All lead-in ducts that contain a joint between ducts or ducts and bends will have those joints made using suitable solvent weld cement.

67 6.6.5 Position Wherever possible and by maintaining the minimum separation distances from other utility plant the ducts should be sited: Unmade surface Verge Footway Carriageway This order of preference should provide the most economic construction costs to the University. The Vendor will be responsible for the preparation of all excavation planning and routing. Estates agreement is required to all proposed routing of trenches and chambers. The Vendor is to obtain cable and other service clearances from Estates before any excavations are commenced. The Vendor will be responsible for any repairs required to services damaged during the works, unless previously identified on any condition survey Line of Duct Lay The line of duct lay will be as straight as possible taking account of surface types and costs, and the position of other utility plant. It is essential that the Vendor take cognisance of this when preparing proposals and documents Roding and Roping The contractor may use either continuous or 3m sectional rods to complete this task. The contractor shall ensure that his actions do not cause any damage to existing cables. For this purpose the contractor will use Leader and Follower devices on the ends of the rods. The practice of blowing a rope using a compressor and a chute shall not be tolerated. Only one draw rope may be installed into a duct at one time. The contractor shall be responsible for provision of all roding, temporary roping and any pumping and drainage equipment necessary to clear any flooded installation. All new duct sections will be left suitably roped. All loose ends will be neatly secured to chamber furniture, in a safe position. Draw rope previously used for drawing in fibre tubing or cable will not be re-installed into a duct. Draw rope lengths will only be joined together using rope splicing techniques; knots will not be permitted. All draw rope and draw cords will be of polypropylene or other non-biodegradable plastic and have a minimum breaking strain of 550kg. The use of duct motors of the inflation/deflation type is essential where cables exist in the duct to be roped. Rods are not to be used where an unprotected cable exists in a duct Marker Tape Fibre - A non-degradable plastic coated aluminium foil marker tape shall be laid in the trench 100mm above the invert of the top duct / ducts. The tape shall be 150mm wide and be marked at 1200mm centres with bold contrasting lettering FIBRE OPTIC CABLE BELOW. The tape will be of a colour that will make it readily visible if exposed during subsequent excavations.

68 Copper - A non-degradable plastic marker tape shall be laid in the trench 100mm above the invert of the top duct / ducts. The tape shall be 150mm wide and be marked at 1200mm centres with bold contrasting lettering TELECOMMUNICATIONS CABLE BELOW. The tape will be of a colour that will make it readily visible if exposed during subsequent excavations Building Entry Sealing Where cables enter the building either inflatable BT style bags or Hawke glands must be used within the mouth of the twin walled ducts Route Deviation Duct runs must follow point-to-point straight lines with access pits provided at 100 metre intervals and at all points where deviation will exceed 1 in 30 horizontally or 1 in 60 vertically. However, long, slow curves are permitted providing the maximum pulling weight of the cables to be installed will not be exceeded. Building entrance deviation is to follow a 600 mm or greater radius Ducting Depth The depth of the ducts must be measured from the top of the duct to the surface of the ground. The following table details the minimum depths required. Environment Depth (mm) Pavement or Grass 500 Verge 600 Urban Roads 750 Table 7 Duct Depth Duct Construction The design of the duct must be as detailed below.

69 Figure 49 Ducting section Testing All ducts must be tested prior to any sub ducts or cables being pulled. A mandrel of length 250mm and a diameter of 90% of the internal diameter of the duct must be pulled through the entire length of the duct. The mandrel must have a rope attached to both ends to allow the mandrel to be withdrawn in the event of a blockage. If the mandrel is pulled through with debris attached then a brush of length 200mm and a diameter of 110% of the internal diameter of the duct must be drawn through in the same way as the mandrel. Once the duct is clear of debris and a mandrel can be drawn through without obstruction a draw rope must be installed as detailed above.

70 Chambers Chambers can be of preformed plastic construction for sized up to 1310 x 610mm.

78 9.0 Roles and Responsibilities 9.1 General The design of the cabling system will include input from the Building Designer, Main Building Contractor, Electrical Contractor, Specialist Data Contractor, Estates and Facilities Project Leader and COMPUTING SERVICES. Close liaison between all parties is required to deliver building design and services suitable for installation of structured wiring to EN & EN It is anticipated that the Main Contractor will appoint a competent Data Contractor. Corporate membership by the Data Contractor of BICSI and individual qualification to BICSU RCDD standard should be considered favourably alongside other accreditations the Main Contractor may require. Key points to take into account during the design phase include Number of points required Cable pathways Building and Floor distributors (hub rooms) specification Power and cooling Component choice Installation scheduling Quality control 9.2 Responsibilities The responsibilities for the installation of the cabling system are as follows: Building Designer Provide Building Distributors and Floor Distributors (hub rooms) to the specification provided by COMPUTING SERVICES (below). Provide details of locations and quantities of hub rooms and data outlets along with detailed drawing to COMPUTING SERVICES. Accurate drawings are to be issued prior to start of wiring system installation showing individual outlet positions with single/double/quad outlets being clearly marked. As a guide, in single occupancy offices there should be a minimum of three data points installed within 1.5m of the anticipated primary desk location. Final design to be agreed with COMPUTING SERVICES and Estates. Main Contractor Data Contractor Provide services to support equipment racks in each hub room. To include power, cooling (air conditioning), lighting, fire detection and containment for cabling. Provide cable pathways sufficient to accommodate structured cabling system (including allowance for any future expansion). Ensure earthing and bonding compliance to BS EN Provide two diverse duct routes into the building, linking into the existing University duct system so as to provide diverse routing of cables to the Data Network core.

79 Design cabling system. Supply and install equipment racks. Install and test of cabling system. Install and test of fibre optic links between hub rooms. Install and test fibre optic links to the University s data network (external to the new/refurbished building). COMPUTING SERVICES To approve the design of the cabling system. Design Data and VOIP installations at the service level. Provide estimates of cost for data and VOIP networks when required. Obtain, install and commission active data equipment. Estates & Facilities Project Leader Ensure information regarding the project, particularly the quantities and types of service, reaches COMPUTING SERVICES in order to obtain estimates of cost. Receive COMPUTING SERVICES estimates of cost for installation of data and VOIP services and incorporate them in the project financial plan. Obtain approval for expenditure. Provide charge code and schedule of dates and areas to be connected. Ensure cable duct routes from the University duct system to the entry points of the new building so as to provide diverse routing of cables to the Data Network core. Must provide a patching schedule of points to be activated a min of 2 weeks prior to activation taking place. Co-ordinate communication between all interested parties. Estates & Facilities Ensure information regarding Access Control and BMS is passed to the project leader and COMPUTING SERVICES. 9.3 Details This section provides further details of individual items required by COMPUTING SERVICES. Building Designer 1. Building/floor distributors (hub rooms) Ensure that there are adequate hub rooms to service the building and that no office outlet is more than 60 metres cable distance from a hub room. Design each hub room to accept at least one 800mm x 800mm equipment racks. The space required for a room containing two racks is approx 2800mm x 2000mm to allow an engineer to gain safe access to the front, rear and side of rack, and the doors to open fully. As an estimate, the amount of space required within a rack for active equipment will be equal to the amount of space taken by passive components.

80 Main Contractor 1. Services in hub rooms Provide power from a dedicated single outlet (not a fused spur) to each power distribution block. The socket must be secured is such a way that the plug top cannot be casually removed or switched off (e.g. located in a secure enclosure or mounted out of normal reach). Provide air conditioning (cooling) to counteract the heat produced by the equipment in the rack: for reasons of access and ensuring that condensate cannot enter the equipment rack, the air conditioning must not be located above the rack. Provide lighting for safe working in the equipment rack. If the room has no windows then an emergency light fitting is to be provided. Provide fire detection associated with the building system for remote fire monitoring. Provide containment within each hub room to accommodate the structured and fibre optic cabling. Provide earth terminal point for connection of equipment rack to building earth system. 2. Cable Pathways Provide a comprehensive distribution network of cable pathways radiating from each data equipment room to conduct individual service cables to their rooms. The distribution must be accessible throughout its length to facilitate installation of additional circuits and to enable fault investigation. Within the rooms provide trunking with separate lids for mains and structured wiring. Provide cable pathway from the building distributor (hub room) to the cable entry point of the new building. All pathways must maintain adequate separation from sources of electrical interference. Extensive guidance on pathway design is provided in the standards. Data Contractor 1. Equipment Racks Provide and install all racks, including those for active equipment to be installed by the University. 2. Structured Wiring Provide, install and terminate all structured cables (including cables for Access control, BMS and any other services that are expected to run on the University s data network). These cables start at the destination office where they are terminated in an RJ45 faceplate. It is essential that a loop of cable is left within the outlet box for future re-terminations. At the rack all cables are to be terminated on RJ45 patch panels. Cables to be tested with tester that is certified for testing the installed cabling and the results supplied to COMPUTING SERVICES. Circuits are to be labelled at both ends in accordance with COMPUTING SERVICES standard. 3. Building Distribution (BD) Fibre Optic The Data Contractor will install, terminate and test all BD fibre optic cables.

81 4. Campus Distribution (CD) Fibre Optic The Data Contractor will install, terminate and test all CD fibre optic cables. COMPUTING SERVICES 1. Structured Cabling System COMPUTING SERVICES will approve the design, the cable and components for the structured cabling system that has been proposed. 2. Design of Data and VOIP Installation COMPUTING SERVICES will design the Data and VOIP installations at the service level for the new building. All proposed outlets will be fully activated. COMPUTING SERVICES will provide estimates of cost for the Data and VOIP networks when required. This will take into account that COMPUTING SERVICES will be providing enough active equipment to activate all proposed outlets. 3. Installation of Active kit COMPUTING SERVICES will procure install and commission all active data equipment. This will include the supply and installation of UTP and fibre patch leads at the equipment rack end. Estates & Facilities Project Leader 1. Access Control and BMS Support of Access control and BMS is not provided until after building handover, due to the fact that COMPUTING SERVICES need to install the active equipment that connects to the University s data network. If Access control and BMS are required before building handover, the following items need to be completed. The building distributor (hub room) needs to be in a completed state with all structured cabling and fibre links external to the building installed and tested. This must include the data cables to the Access and BMS controllers. COMPUTING SERVICES staff must be able to get access to the hub room to install power on the active equipment and link it to the Universities data network. Once the active equipment has been installed and switched on there must be no interruptions to the mains power supply feeding the rack. COMPUTING SERVICES will notify the type and number of lock to be fitted to doors The hub room will be in a clean sterile state with all works completed. To determine the number and location of DDA refuge call phones throughout the building. To determine the number and location of public emergency and lift phones throughout the building.
