Telecommunication SpacesGeneral specifications

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

main telecom room

mobile-service room roof-top mobile-service room floor telecom closet

In multi-storey buildings the telecom rooms should be vertically aligned and linked by a sharedcontainment system. This containment system must not reduce the minimum requested space.

All telecom rooms must be dedicated to the use of du. The rooms must be easily accessible to dupersonnel 24 hours a day and secured from unauthorized 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)


6/72

All telecom spaces and pathways must be pest controlled using best available practices. It should benoted 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 andpathways. This could involve the installation of covers to cable trays; if this is the case these coversmust be removable to allow for the installation of additional cables.

The walls, floor, and ceiling should be painted and treated with anti-dust and anti-static coating tominimize dust and static electricity. Walls and ceilings shall receive primer and finish coat of light colorpaint.

In order to move equipment into and out of telecom rooms, all entrances must not be smaller than

900mm x 2100mm (WxH)

Safety and other considerations

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

all telecom spaces should be fitted with smoke detectors connected to the building managementsystem

all telecom spaces should be fitted with normal and 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 labeled. the room must be free from contaminants and pollutants.

required in the building (more than G+10) the 1 st mobile service landing room can be shared with theMTR. The minimum room dimension should be 4mx4mx3m (WxDxH) depending on the functions andfeatures of the building. The room specifications are detailed in Table-1 and Appendix_1_Figure-5 to 9.

If the architectural design limits the room sharing, then two dedicated rooms with minimum sizes of 3mx3 m x 3m (WXDXH) each must be provided. The room specifications are detailed in Table-2 and

Appendix_1_Figure-1 to 3, 18. Refer to appendix_1_Figure-14 to 16 for Rack elevation layouts details.

The 3 m clearance height specified is the minimum finished clearance after taking into accountallowances for raised floors (if used), overhead cable trays and any other obstructions such aslighting fixtures and beams. In areas where overhead trays are used, a minimum headroom access of300mm is required above the tray.

Depending on the telecom room usage, a “raised floor” might be required inside the MTR having activeequipment, particularly commercial or mixed used buildings. A minimum of 300mm height above the basefloor of the room should be provided. Tile Cutting details are specified in appendix_1_Figure-25. In othercases involving residential buildings, raised floor is not mandatory, and will be further advised during theNOC stage.

The floor level of the room must be constructed at the same level as the outside access or corridor. If thiscannot be met, then a suitable ramped entry with an anti-slip surface must be provided. A threshold stepof 100mm must also be provided inside the room under the raised floor to prevent any ingress of waterfrom outside the room.

The door of the main telecom room must have outward opening with size not smaller than 900mmx 2100mm (WxH). The door should be labeled

PathwaysGeneral specifications

The following requirements must be applied to all containment systems: the containment system must be designed so that installed cables do not exceed the minimum

specified bend radius all metal containment parts must be free from sharp edges and earth bonded telecom riser openings must be sealed with a suitable fire retardant material cable trays must be easily accessible in common areas to facilitate any future provision of

additional cables any cable trays that are in areas accessible to the public and less than 4.8m above the floor must

be covered containment systems must not run through areas exposed to excessive heat, moisture, corrosive

atmospheric or environmental conditions, high voltages, radio frequency interference (RFI) or

electro-magnetic interference (EMI) for all containment systems a minimum separation must be maintained from sources of

electromagnetic interference. the building developer may want to consider redundant containment systems, particularly in


13/72

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

Vertical Containment - within homes

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

Horizontal Containment – multi-storey / multi-tenant buildings

Floor telecom closet to consolidation points

The horizontal containment for routing cables from the floor telecom closets to consolidation points on theserved floor can use a number of systems (cable trays, conduits, etc.). The solution will depend on thecharacteristics of the building type. Conduits must only be used when the consolidation point locationsare 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 150 mm (HxWxD)must be provided on individual runs that exceed 30m. PVC junction /pull boxes must also be providedwhere 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 mainroute from floor telecom closet to main corridors and then branches to each consolidationcabinet through cable trays of 50mm x 50mm (WxH)


14/72

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 asingle tower still apply. In addition, cable trays must be provided linking the main telecom rooms of alltowers, exact requirement to be finalized 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 additionalcables. 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.

CablesGeneral 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 definedrequirements. Cable test must be performed using power meter and OTDR tests, whichever is applicable.Details for cable labeling are included in Appendix_2.

Fiber Optic Cables

The quantity of fiber optic cables that must be provided and installed from the main telecom room to theconsolidation points or FTC depends on the characteristics of the building.

Drop Fiber Cable

indoor rated drop fiber


15/72

OSP Fiber Cable

outdoor rated single mode compliant with ITU-T G.652D loose tube inner construction or Ribbon type for high density cables Fiber optic coloring code shall be in accordance to EIA/TIA-598

Fiber Optic Cables Requirements – from main telecom room to consolidation points (direct fiber)

2 core (individual pair) fiber optic cables will be required from Main Telecom Room up to each apartment,

retail shop, and pre-defined office. It is recommended to apply direct fiber installation up to G+30 only tomaintain cable management inside the FTC and MTR.

The fiber cables must be provided from the main telecom room to each consolidation point and should beof continuous lengths free from joints, branches or patching. By default, all the fiber cables should passthrough the floor telecom closet.

The fiber cables should be labeled at both ends with a unique reference for the consolidation point servedand the room or area of origin. Labeling details are included in Appendix_2.

All fiber optic cables should be terminated inside the Main Telecom Room and inside the unit CP cabinet.Refer to appendix_1_figure-19.

Fiber Optic Cables Requirements – from main telecom room to FTC (multicore fiber)

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

If there are unused fiber cores, these must be left un-terminated and coiled properly inside the mini ODFand the MTR ODF Refer to appendix 1 figure-26


16/72

2 single mode fiber pair cables must be provided from the main telecom room to the roof-top mobile-

service rooms. 10m of spare fiber must be left neatly coiled.

CAT6 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 buildingdeveloper. However, the following minimum requirements must be followed for the efficient and effectiveprovision of services:

the cables must conform to a minimum of CAT6 specification (Category 6, 100 Ohm, 4pair 24 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 and 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

labeled 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 CAT6 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 CAT6 cabling system must be tested using an appropriate field test instrument for

17/72

Bulk Service Application

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 to both du and the client. In such case 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.

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.

In case that 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 finalized during the NOC stage.

Cable connectivity between du and the client rack or room must conform to the cabling standard of du, as


18/72

final requirement will be finalized 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 main telecom room to the plot boundary. Theexact connection points at the plot boundary will depend on whether the du network already reaches theplot.

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 plotboundary.

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 will be for the exclusive use of du. The quantity and size of these ducts for different kindof developments is detailed in Table-7. Refer to the Appendix_1_Figure-23 to 24.


19/72

In case of combined plots, two entry locations are still required for primary and secondary networkconnections; this will be advised by du at the design stage.

Lead-In ducts - complex of villas

In the case of a complex of villas the building developer must connect the lead-in ducts to each villa in thecomplex. 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 ona 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 areaaccessible 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) willbe required for each pair of D54 entry duct pipes.

Lead-In ducts – entry box

Entry boxes are required to install telecom cables through the lead-in duct. The type and size of entry/pullboxes will depend on the characteristics of the building development. The details for entry boxes areincluded in the text below and summarized in Table-7. The quantity and location of the entry boxes willdepend on the route from the main telecom room to the network
