Introduction

We are pleased to issue the updated

Telecommunications Infrastructure

Standards for Buildings v.5.

The new design guidelines in this

document are based on our prior

experience of offering quality

telecommunications services to our

consumer and enterprise customers

across UAE.

The purpose of this document is to:

• Introduce the new design

guidelines for fibre infrastructure

to enable property developers,

consultants, and contractor

to deliver high-quality,

future-proof telecommunications and

multimedia services to their

tenants.

• Provide a guide for consultants,

contractors, and engineers related

to the ‘No Objection Certificate’

(Building NOC) process that

includes design and construction

drawing review and Structure

Cabling Material data sheets

review, with samples checking and

site inspections required during

implementation.

• Meet the growing demand for

improved communications at work,

at home, in business, and in public

services.

We advise our clients to use qualified

and certified professionals in all

aspects of the application and

implementation of these design

guidelines during building construction

stages.

Developers are encouraged to engage

with us in the early stages so that any

process and/or design issues may be

resolved.

If property developers or tenants have

special requirements that may not

be covered by these guidelines, it’s

necessary to involve our design teams

at an early stage of development

planning, to enable seamless delivery

of premium telecommunications

services at launch.

We look forward to feedback from

developers as it helps us understand

your issues and incorporate valid

suggestions in future designs.

Safety and other

considerations

All telecom rooms must comply with municipality and national authority standards and regulations, such as those issued by civil defence and utility companies. Notwithstanding this, it is expected that the following will be provided:

• All telecom spaces should be fitted with smoke detectors connected to the building management system. • All telecom spaces should be fitted

with emergency lighting.

• All containment openings to telecom spaces must be sealed with a

regulation fire retardant material. • All doors to telecom rooms must be of solid wood core or steel construction, fire retardant with a minimum rating of 2 hours.

• All doors to telecom rooms must be outward opening with an automatic door closer system fitted on the hinged edge.

• All doors to telecom rooms must be labelled.

• The room must be free from contaminants and pollutants.

• All telecom rooms should have basic firefighting provision of handheld CO2 cylinder type extinguishers.

• If the building developer has any concerns over safety, especially fire protection and suppression systems, this should be raised with du at the NOC stage.

Temperature

and humidity

All telecom rooms must be maintained at 20°C ± 3°C and the relative humidity at 50% ± 10%. However, floor telecom closets can be maintained within 20°C to 30°C temperature range.

The Main Telecom

Room (MTR)

A main telecom room must be provided on the ground floor for all multi-storey buildings. This room will be used for the termination of telecom fibre optic cables and to house telecom equipment, if needed, now or in the future.

Generally, the MTR can be shared by both du Fixed and Mobile services. If a mobile service room is required in the building (more than G+10) the first mobile service landing room can be shared with the MTR. The minimum combined room dimension should be 4m x 4m x 3m (WxDxH) and maybe increased depending on the functions and features of the building. The room specifications are detailed in Appendix_1_Figure 5 to 9. If the architectural design limits the room sharing, then two dedicated rooms with minimum sizes of 3m x 3m x 3m (WXDXH) each must be provided.

The room specifications are detailed in

Table-1, Table-2, and Appendix_1_Figure-1 to 3 and 18.

Refer to Appendix_1_Figure-14 to 16

for Rack elevation layouts details.

General

specifications

A number of telecom rooms will be required in a building depending on its characteristics. The following room types are required and the details of these rooms shown below:

• Main telecom room • Mobile service room

• Rooftop mobile service room • Floor telecom closet

In multi-storey buildings the telecom rooms should be vertically aligned and linked by a shared containment system. This containment system must not reduce the minimum requested space. All telecom rooms must be dedicated for the use of du. The rooms must be easily accessible to du personnel 24 hours a day and secured from unauthorised entry.

Telecom rooms must not be in close proximity to any sources of the following: • Heat

• Moisture

• Corrosive atmospheric or environmental conditions • High voltages

• Radio frequency interference (RFI) • Electro-magnetic interference (EMI) The rooms must not be directly beneath or next to wet areas such as:

• Showers • Washrooms • Swimming pools • Garbage area

The rooms should be clean and free from any items not directly related to the specifications in this document such as: • Non-du equipment

• Utility pipes • Sprinkler systems • Windows

All telecom spaces and pathways must be pest controlled using best available practices. It should be noted that rodents often gnaw cables resulting in damage and the potential for service disruption. Hence, special attention should be given to preventing rodents from entering telecom spaces and pathways. This could involve the installation of covers to cable trays; if this is the case these covers must be removable to allow for the installation of additional cables.

The walls, floor and ceiling should be painted and treated with dust and anti-static coating to minimise dust and anti-static electricity. Walls and ceilings shall receive primer and finish coat of light colour paint. In order to move equipment into and out of telecom rooms, all entrances must not be smaller than 900mm x 2100mm (WxH).

(7)

Floor Telecom

Closet (FTC)

A floor telecom closet must be provided on each floor of all multi-storey buildings. The floor telecom closet is required to provide a flexible point for the installation, pulling and maintenance of telecom cables. FTC must have a minimum dimension of 2m x 1m x 3m (WXDXH).

The floor telecom closet should be

provided with two outward opening doors with a minimum total opening of 1500mm x 2100mm (WxH). The door should be labelled (Floor Telecom Closet تامدخ ةرجح ةيقباطلا تلااصتلاا )

In the case of a multi-storey villas, townhouses, G+1 warehouses or small retail shops, floor distribution boxes will be required with a minimum size of 300mm x 300mm x 150 mm (WxHxD), as an alternative to replace FTC.

In high rise buildings which usually exceed 30 floors, proper planning and consideration must be given to the FTC space and dimension, which might be increased. It is highly advisable to seek du advice and pay close attention during NOC stage to understand the concept of high rise building infrastructure design. Refer to

Table 3 and 4 and Appendix_1_Figure-4

for the complete detailed layouts of FTC.

Rooftop mobile

service room

(up to G+10)

Rooftop mobile service rooms must be provided on the roof of all multi-tenant buildings up to G+10 and access must be provided to the building riser system. The door dimension must be 900mm x 2100mm (WxH) and opening outwards and should be labelled ‘Roof Telecom Room’

The rooftop mobile room must have a minimum distributed floor load rating of 10 kN/m2.

An opening must be provided with a dimension of 600mm x 400mm (WxH), 500mm below the room ceiling in walls facing the building’s rooftop area.

Space must be reserved on the rooftop of the building for the installation of mobile service antennas. This will vary from building to building, but will typically be at the corners of the building or on any raised structure on the rooftop. The exact details will be defined during the NOC stage. Refer to Appendix _1_Figure-10 for the complete detailed room layouts for mobile service rooms.

Home consolidation

cabinets

The home consolidation cabinet is a space to house du’s network termination equipment. It also serves as the

distribution point for all local wiring. A consolidation cabinet should be provided in each home. This should be a telecom cabinet with the following specifications: • Minimum internal dimensions 600mm

x 600mm x 15٠mm (HxWxD) for 24 or less CAT6 cables termination per unit • Minimum internal dimensions 600mm

x 600mm x 300mm (HxWxD) for more than 24 CAT6 cables termination per unit

• Wall mount or flushed mount installation at 1.2m high measured from the

finished floor level up to the edge of the cabinet.

• Fitted with RJ45 UTP patch panel and cable management.

• Fitted with 2-core fibre terminal box. • 2 nos. 13A twin sockets fed from the

essential power supply with dedicated The 3m clearance height specified is the

minimum finished clearance after taking into account allowances for raised floors (if used), overhead cable trays and any other obstructions such as lighting fixtures and beams. In areas where overhead trays are used, a minimum headroom access of 300mm is required above the tray. Depending on the telecom room usage, a ‘raised floor’ might be required inside the MTR having active equipment, particularly commercial or mixed use buildings. A minimum of 300mm height above the base floor of the room should be provided. Tile cutting details are

specified in Appendix_1_Figure-25. In other cases involving residential buildings, raised floor is not mandatory, and will be further advised during the NOC stage.

The floor level of the room must be constructed at the same level as the outside access or corridor. If this cannot be met, then a suitable ramped entry with an anti-slip surface must be provided. A threshold step of 100mm must also be provided inside the room under the raised floor to prevent any ingress of water from outside the room.

The door of the main telecom room must have outward opening with size not smaller than 900mm x 2100mm (WxH). The door should be labelled ‘Main Telecom Room’ “تلااصتلال ةيسيئرلا ةفرغلا

All cables in the main telecom room must be properly routed to the desired destinations. For this purpose, an

adequately sized cable tray system must be installed to maintain the connectivity as described in Appendix_1_Figure-20 to 21.

Clustered buildings

Group of towers

If a project consists of a cluster of multi-tenant buildings, then all the requirements of a single tower still applies. One of the buildings will be selected as the location for the main telecom room, which usually stands in the centre of the cluster or often times closest to the main telecom duct entry points. This would require the cluster of buildings to be linked to the designated main telecom room via multicore single mode fibre cables. The details of this arrangement should be discussed with du during the NOC stage. Cabling concept is described in the clustered building schematic diagram in Appendix_1_ Figure-22.

The Mobile

Service Room

(more than G+10)

As mentioned in the MTR section, du Fixed and Mobile Services can be combined in one room. The first mobile service room can be shared with the MTR to serve the first 10 floors of the building. If sharing is not feasible, a dedicated 3m x3m x 3m (WXDXH) mobile service room can also be provided. Accordingly, the mobile service rooms must be provided for every 10 floors thereafter. The locations of the mobile service rooms must be close to the floor telecom closet (FTC).

The mobile service rooms must have a minimum distributed floor load rating of 10 kN/m2. The door dimension must be 900mm x 2100mm (WxH) and opening outwards.

Vertical

Containment

Multi-storey/multi-tenant buildings

Risers must be provided in multi-storey/ multi-tenant buildings to allow the installation of telecom cables from the main telecom room to the floor telecom closets, mobile service rooms and rooftop mobile service rooms. Hot-Dip Galvanized (HDG) slotted steel cable trays must be provided in the risers to carry the telecom cables between all the telecom rooms. It is recommended that the main telecom room and floor telecom closets should be designed so that they are vertically aligned within the building.

Two cable trays, with the following minimum dimensions are recommended: • One of 500mm x 100mm (WxH) with Heavy Duty Return Flange (HDRF) for fibre optic cables.

• One of 300mm x 50mm (WxH) with Heavy Duty Return Flange (HDRF) for GSM cables (covering all floors from last basement till roof).

If it is not possible to provide all of the cable trays running vertically then horizontal trays of the same size should be provided.

Note: above cable trays requirements to be finalised during NOC stage.

Within homes

In case of multi-floor apartments/villas, the UTP cables between the floors must run through 50mm diameter PVC conduits via junction/pull boxes located on each floor. The junction/pull boxes must have a minimum dimension of 300mm x 300mm x 150mm (WxHxD). The slab opening for these conduits must be in a suitable and accessible location in every floor. It is recommended that all vertical conduit runs be aligned to ease the installation of cables.

Horizontal

Containment

Multi-storey/multi-tenant buildings

The horizontal containment for routing cables from the floor telecom closets to consolidation points on the served floor can use a number of systems (cable trays, conduits, etc.). The solution will depend on the characteristics of the building. Conduits must only be used when the consolidation point locations are permanent, the cable density is low and the flexibility to modify the routing is not required. Specification for the size of this containment is given in

Appendix_1_Figure-20 to 21

Note: Intermediate PVC junction/pull boxes with minimum size of 300mm x 300mm x 150mm (HxWxD) must be provided on individual runs that exceed 30m. PVC junction/pull boxes must also be provided where an individual conduit run has a sharp change in direction.

The cable tray minimum dimensions are described below:

• One 200mm x 50mm (WxH) cable tray with Heavy Duty Return Flange (HDRF) as a main route from floor telecom closet to main corridors and then branches to each consolidation cabinet through cable trays of 50mm x 50mm (WxH).

Mobile service antennas

Cable trays must be provided to route mobile service antenna cables from the floor telecom closets to all common corridors including all lift lobbies in all floors including podium and basement.

One cable tray following minimum dimensions must be provided:

• 150mm x 50mm (WxH) with Heavy Duty Return Flange (HDRF)

For office/commercial buildings, the horizontal containments should be extended till inside the entrance of each office units.

Within homes

All UTP cables inside the home must run through PVC conduit with a minimum 25mm diameter from the home

consolidation point to each dual outlet. If more than one dual outlet is fed by a conduit then the size and quantity of the conduit may need to be increased. Intermediate PVC junction/pull boxes must be provided on individual runs that exceed 30m. PVC junction /pull boxes must also be provided where an individual conduit run has a sharp change in direction.

Cluster of buildings – groups of towers

Where a building consists of a group of towers (on a common shared podium) all of the requirements of a single tower still apply. In addition, cable trays must be provided linking the main telecom rooms of all towers, exact requirement to be finalised during NOC stage.

One cable tray with the following dimension must be provided:

• 300 x 100 (WxH) with Heavy Duty Return Flanged (HDRF)

These trays should be readily accessible in common areas to facilitate any future provision of additional cables. However, if these trays are in an area accessible to the public and are less than 4.8m above the floor then the trays should be covered. For more details, refer to Appendix_1_ Figure-22

(11)

General

specifications

Specifications of all the cables to be used must be submitted to du for approval during the NOC stage. This must also include test reports showing that the performance of the cabling system meets defined requirements. Cable test must be performed using power metre and OTDR tests, whichever is applicable. Details for cable labelling are included in Appendix_2

Fibre Optic Cables

The quantity of fibre optic cables that must be provided and installed from the main telecom room to the consolidation points or FTC depends on the

characteristics of the building.

Fibre optic cable requirements – from main telecom room to consolidation points (direct fibre)

2 core (individual pair) fibre optic cables will be required from MTR up to each apartment, retail shop, and pre-defined office. It is recommended to apply direct fibre installation up to G+30 only to maintain cable management inside the FTC and MTR.

The fibre cables must be provided from the main telecom room to each consolidation point and should be of continuous lengths free from joints, branches or patching. By default, all the fibre cables should pass through the FTC. The fibre cables should be labelled at both ends with a unique reference for the consolidation point served and the room or area of origin. Labelling details are included in Appendix_2

All fibre optic cables should be terminated inside the MTR and inside the unit CP cabinet. Refer to Appendix_1_figure-19

(12)

Fibre optic cable requirements – from MTR to FTC (multicore fibre)

For high rise buildings exceeding G+30, a FTC must be selected for every 10 floors. Multicore fibre cable must be installed in a mini ODF inside the FTC, where the number of fibre core will depend on the number of units in each served floor. 2 fibre cores per unit should be considered as the basic foundation of multicore fibre calculation.

If there are unused fibre cores, these must be left un-terminated and coiled properly inside the mini ODF and the MTR ODF. Refer to Appendix_1_figure-26

Fibre optic cable requirements – from MTR to FTC (shell and core)

For shell and core office development, one pair of fibre optic cable per 200sq m of leasable commercial area should be provided up to FTC of the same floor. Depending on the building design and built up area, multicore fibre cables from 12 cores up to 288 cores may be required to be installed between the MTR and FTC to meet the cable quantity requirement.

The fibre cables should be labelled at both ends with a unique reference for the floor served and the MTR. Labelling details are included in Appendix_2

All fibre optic cables should be terminated inside the MTR and in the FTC mini ODF cabinet. Refer to the FTC layout as shown in Appendix_1_Figure-4

Fibre optic cables – from MTR to all mobile service rooms

12 single mode fibre pair cables must be provided from the main telecom room cascaded to all mobile service rooms ending at the last mobile service room. 10m of spare fibre must be left neatly coiled.

Fibre optic cables – from MTR to rooftop mobile service room

CAT6 Copper

Cables

CAT 6 Copper cables – from

consolidation points to tenant outlets

To deliver services from the consolidation points to the building outlets, unshielded twisted pair (UTP) copper cables must be provided. The complete design of this service is the responsibility of the building developer. However, the following minimum requirements must be followed for the efficient and effective provision of services:

• The cables must conform to a minimum of CAT 6 specification (Category 6, 100 Ohm, 4 pair 23 AWG as specified in ANSI/TIA/EIA 568-B.2 Addendum 1). • The wiring must be in a‘star’topology fanning out from the consolidation point.

• Dual RJ45 outlets with spring load sliding shutters must be provided wherever service is required (all outlets should comply with the performance specifications as detailed in ANSI/TIA EIA 568-B.2 Addendum 6).

• Each socket in the dual RJ45 outlet must

be wired back to the consolidation point. • Outlets must not be cascaded or looped

& there must be no splitting of cable pairs.

• The maximum cable length from consolidation point to outlet must not exceed 90m.

• At the consolidation point the cables should be terminated on an RJ45 patch panel and labelled with the socket and outlet served.

• In each outlet the cable must be terminated to maintain the twists in each pair up to within 5mm of the termination.

• Proper strain relief should be provided at the terminated ends of the cable. • The components of the CAT 6 system

must be from the same supplier or at least compatible to insure maximum performance.

• Design should incorporate built-in flexibility to meet the growing needs of the occupants.

• The CAT 6 cabling system must be tested using an appropriate field test instrument for compliance with ANSI TIA/EIA 568-B.2 Category 6 (or

equivalent if a higher specification has been used)

• Numbering and colouring of the pairs should be as defined in EIA/TIA 568B, SO 11801/EN50173 using the T568B option.

Administration and

labelling scheme

All the infrastructure components described in this document must be clearly and uniquely labelled. The label information must correspond with the description on the as-built drawings.

The type of label must be suitable for the object being labelled and its environment. This is particularly important for cables and consolidation cabinets where a high quality printed self-laminating type must be used. For detail of the Labelling scheme refer to the Appendix_2

(13)

Bulk service

application

Bulk service

requirements

This kind of service solution usually applies to buildings that are having their own IT network and system operator, such as hotels, hospitals, schools, universities, banks, airports, warehouses, workshops and other similar establishments. Sharing the client server or IT room with du can be one solution to deliver the services simply and quickly which is convenient for both du and the client. In such cases of room sharing, free space inside the client room needs to be provided and reserved for du usage. Free space could be either rack unit space in an existing client rack or a floor space inside the room to accommodate a floor mounted rack dedicated for du. A letter from the client should be

submitted during the building NOC stage confirming the bulk service request with detailed information on the required telecom services.

The consultant is advised to approach du prior to the Building NOC submission to be able to assess and decide if sharing the space with the client is the best approach or a dedicated du room is technically recommended for some reason or another. If a dedicated room is required by du, the room specifications as mentioned in the telecom spaces section must be followed. The final du requirements including space, containment, cabling and power will be finalised during the NOC stage.

Cable connectivity between du and the client rack or room must conform to the cabling standard of du, as discussed in the cable section of this document. Single mode fibre, UTP CAT6 and multi pair CAT3 copper cables are generally required, to be supplied, terminated and tested. Final cabling connectivity design including cable type and quantity will be advised during the NOC stage. Refer to the

(14)

Other special

requirements

Public phones, ATM machines and retail kiosks

Provision needs to be made for the connection of public phones, ATM

machines and retail kiosks. This must use the same design as that prescribed for commercial buildings; 2-core single mode fibre (individual pair) from the main telecom room to a business consolidation cabinet must be installed. The final requirement will be finalised during the NOC stage. The business consolidation cabinet must be in a secured location. It is the responsibility of the building developer/consultant to coordinate with du at the NOC stage for any special or non-standard requirement.

Entry ducts

The building developer must provide lead-in ducts from the malead-in telecom room to the plot boundary. The exact connection points at the plot boundary will depend on whether the du network already reaches the plot.

Option 1 – du duct network already exists • The building developer will be

responsible to connect to the du ducting system.

• The operator will identify the location and quantity of their lead-in ducts. Option 2 – du duct network is still to be built

• The building developer will be

responsible to extend the lead-in duct to 1m outside the plot boundary. • The building developer is responsible for locating and clearly identifying lead in ducts.

In both cases the building developer will be responsible for the maintenance and repair of lead-in ducts. The lead-in ducts systems in this document are designed to meet du requirements to serve the development, building or property and must be used for telecommunication purposes. The quantity and size of these ducts for different kind of developments is detailed in Table-6. Refer to the Appendix_1_Figure-23 to 24

The lead-in duct specifications are as follows:

• Made from black uPVC.

• Upmost part of ducts must be buried to a depth of 600mm below finished ground level.

• Clearly marked above ground level for easy location.

• Sloping away from the building. • Protected by concrete when running under permanent paved surfaces. • Sealed at each end to prevent the ingress of any materials such as water, sub-soil, gas, and pests.

• An entry/pull box must be installed for any right-angled or sharp bends in the lead-in duct route.

• If required at the entry to the main telecom room, a wide-angle long radius bend (factory made) may be provided; alternatively an entry box may also be provided.

• All ducts must include a draw rope made of twisted mildew and rot resistant polypropylene; minimum outside diameter of 6mm; minimum tensile strength of 2400lbs/1000kg/ In case of combined plots, two entry locations are still required for primary and secondary network connections; this will be advised by du at the design stage.

Lead-In ducts – villa complex

In the case of a villa complex, the building developer must connect the lead-in ducts to each villa in the complex. The lead-in duct size must not be reduced until the branching point for an individual villa.

Lead-In ducts – group of buildings

In cases where the building developer wishes to share lead-in ducts between a group of buildings (not on a common shared podium), then the design needs must be discussed with du at the design stage.

Lead-In ducts - building entry

Where lead-in ducts cannot be routed directly into the main telecom room, Hot-Dip Galvanized (HDG) slotted steel cable trays must be provided as an alternative. These trays must be easily accessible in common areas to facilitate any future provision of additional cables. However, if these trays are in an area accessible to the public and are less that 4.8m above the floor then the trays must be covered. A cable tray of minimum dimensions 300mm x 100mm (WxH) with Heavy Duty Return Flange (HDRF) will be required for each plot entry point.

Lead-In ducts – entry box

Entry boxes are required to install telecom cables through the lead-in duct. The type and size of entry/pull boxes will depend on the characteristics of the building development. The details for entry boxes are included in the text below and summarised in Table-6. The quantity and location of the entry boxes will depend on the route from the main telecom room to the network.

Entry boxes must be included wherever the duct system has right-angles or sharp bends or other factors to facilitate cable pulling.

The following specifications must be followed:

• Constructed with reinforced concrete. • Fitted with a ductile iron frame and cover.

• Minimum load rating 400kN.

• Cover to be marked ‘du – Telecom’. • An earth rod must be provided with a resistance of less than 5 ohms.

Note: A more detailed set of entry box specifications and drawings are included in Table-6
