Work affecting existingOpenreach plant
When our network apparatus is affected by the workof others, Openreach, in common with other utilitycompanies, has to follow the correct legal proceduresusing the information provided. This helps toestablish important details such as who must pay forany alteration work and also helps to determine thetimescales which you can expect us to work within.
If your work could affect Openreach plant locatedwithin or over your site, or where your site interfaceswith the public highway, you must provide details toour Network Alterations team. Alternatively, you maywish to request alterations for aesthetic reasons tochange the appearance of your site.
After receiving your proposals, an initial investigationof our records will be carried out to assess thepossible effects.
You will be informed free of charge if it appears thatno chargeable alterations are required, including thenecessary precautions that should be taken.
If alterations are likely, you will receive written detailsof the next steps, normally within 20 working days,including any advance payment required. This willenable us to contact you and carry out a morethorough investigation, normally over the next 25working days, and provide a specification including adetailed costing.
1 It is the responsibility of the OpenreachnewSites representative to inform you of thechosen method of connection to theOpenreach network. This will be determined byavailability in your locality. If you prefer analternative method of service to that proposed,then this will be considered but additionalassociated costs may apply. OpenreachnewSites will endeavour to issue proposals foryour site within a four week timeframe prior toyour intended site start date. However, if yourequire a proposed layout in advance of this, apremium service charge will be applied.
2 It is important that your designated OpenreachnewSites office is supplied with acomprehensive final plan of the site layout,ideally including all postal addressingassociated with your new development. Anysubsequent amendments or layout changes tothe original proposal will require updating andthis will need to be amended by your newSitesdesigner to ensure that a bespoke service isdelivered. Please note: Any re-work requestswill incur relevant charges.
3 We will seek a written agreement in the formof a wayleave from you which will give uspermission to install and keep apparatus onsite to serve your prospective customers. If youare building multi-occupancy properties – forexample flats or apartments – the wayleavemust also include wiring up to and includingthe Openreach Network Termination Point(NTP) at each property.
4 Should you wish to install Openreach plantunder contract as per the Openreachproposals, we will agree for you to proceedproviding that the necessary quality and safetystandards can be met, which could include alicense to work in the public highway.However, work on our existing network canonly be carried out by our own accreditedengineers and designated contractors.
5 Openreach will advise on site on all technicalspecifications including the use of all Openreachmaterials and the positioning of plant.Openreach equipment should only be used forthe installation of our own network. Any otheruse will be deemed to be inappropriate andlegal redress will be sought. If Openreach storesare lost, damaged or misused, the cost ofreplacement will be invoiced against yourcompany.
6 In the case of flats or apartments, where youwish to provide service to individual flats beyondthe intake duct, we will provide materials toserve each flat. We would, however, require youto provide the conduit and/or cable tray and laythe cable supplied in/on it.

11 It is the Openreach policy not to share anyinfrastructure with any other licensed/unlicensed operator. Please contact yournewSites team if you require furtherinformation.
12 Openreach will not normally be involved withthe installation of internal extension sockets orassociated cabling beyond the OpenreachNetwork Termination Point (NTP). However, wecan put you in touch with the correctOpenreach department who can provide adviceand guidance and even undertake such workon request.
13 With the exception of pre-formed chambers,Openreach materials will be delivered free ofcharge on request. We operate a bi-weeklydelivery service to all regions. Therefore earlynotification of requirements is needed. Ifmaterials are required urgently, a small chargecould be incurred.
14 The network apparatus/equipment to beinstalled at your development will be ownedby British Telecommunications plc (‘BT’), andall references to ‘Openreach’ in thisdocument should be read accordingly.Openreach is an operating division of BTresponsible for the physical layers of the BTaccess and backhaul networks. Similarly anycontract with a developer will be with ‘BT’.
If preferred for financial purposes, you may initiallyrequest a budgetary costing that will not includespecific details of the alterations scheme design, butplease note this may increase the overall cost of theinvestigation stages.
Where Openreach consider a detailed investigation isessential to ensure the protection of our network, wewill contact you if no response has been received toour initial correspondence, normally within 30working days.
The programme timescales for completion of anyphysical diversion work can be agreed during thedetailed costing stage or later, and will depend onthe scale of the works required.

Avoiding damage to theOpenreach underground network
Damage to Openreach's network can beexpensive for the damager, Openreach andthe public/public services.
Openreach wants to work with you to avoid thisunnecessary cost, to the benefit of all parties.
Openreach has an extensive underground networkthat can be located inside and/or on the perimeterof a site. This network is vulnerable to excavation-related damage unless appropriate precautionsare taken.
The precautions for avoiding damage tounderground utility plant are contained within theHealth & Safety Guide No. 47: ‘Avoiding Dangerfrom Underground Services’. This document stressesthe need for the availability of utility plans on siteand the use of safe digging practices.
To obtain a more precise location of Openreachapparatus (either within your site or on the adjoiningground) and help avoid costly damage, contact:
Dial Before You DigTel: 0800 917 3993Fax: 020 8326 4050
Email: [email protected]
Damage to Openreach's network can be expensivewith regard to:
Direct Cost - the cost of repair.Operational Cost - delays associated with repair.Social Cost - the off site effects i.e. lossof service to emergency services/centresor the vulnerable in society.

Recommended arrangement of mains in a 2m footway
Installation of Openreach services is to beexecuted using either 50mm or 90mm internaldiameter grey PVC duct supplied by Openreach.
Please be aware that Openreach ducting canonly be used for telecommunications equipmentapproved by Openreach.
All runs should be laid as straight as possible,and deviations should be made by carefullybending the ducts or by the use of pre-formedOpenreach bends.
There should be no more than one pre-formed90° bend in any single run of duct. Pre-formed90° bends should not be installed in any ductlinking two Openreach joint boxes. Footpath orservice strip ducting must be laid at 350mmdepth of cover (NJUG7) and 450mm cover incustomer’s premises.
All space alongside the duct is to be backfilledwith granular fill to a thickness of not less than75mm. All duct is to be provided with adrawrope after installation, unless localagreement is made to substitute the drawropefor lead-in cable.
Please notify your newSites team when duct hasbeen laid and is ready for inspection.
Copies of the NJUG7 recommendation on thepositioning of utilities mains and plant for newworks can be obtained from: The National JointUtilities Group Secretariat, 30 Millbank, LondonSW1P 4RD.

Duct laid beneath a carriageway crossing mustbe 600mm cover from final surface levels and,for engineering reasons (NJUG 7), 600mmseparation from other services laid in parallel or150mm if laid at right angles (see Fig 2).
Road crossing requires 600mm separation fromother services to allow construction ofOpenreach underground joint boxes without theneed for fixed bends.
Where Openreach duct crosses the carriageway,adjoining kerbs are to be marked temporarilydenoting location of duct positions (see Fig 1).
Openreach duct to be laid on outer edge ofservice trench to facilitate box building.
A drawrope is necessary. It is to be insertedthrough the duct and secured to the markerposts at both ends of the crossing to facilitatefuture cabling operations. The appropriate ductplug should be fitted to either end of duct (See Fig 1). Plug Duct 4B Socket End or PlugDuct 4C Spigot End must be inserted to preventingress of foreign matter.
Cable marker No2 will be required at siteentrance/boundary to ensure link upidentification for Openreach contractors.
Non-standard frames and covers are increasingly being fitted by councils and developerson new developments, shopping precincts and pedestrianised areas. While they may besympathetic to the surrounding paved areas, these frames and covers are unapproved andcannot be lifted by traditional means – ie with a Key Joint Box No 5.
Non-standard frames and covers
Openreach will take legal proceedings against anydeveloper who fits non-standard covers and willclaim damages and costs against them.
Approved frames and covers can be recognised bythe embossed markings on each end of the plate.On one end are the markings EN124 (the EUstandard), B125 (the class of EN124) and the BSKitemark. On the other are the identifier of themanufacturer (SID or SGP), the year ofmanufacture (03, 04 etc) and the BT identifier.These are the only frames and covers that canbe used.
Openreach engineers are under strict instructionsnot to attempt to lift non-standard covers until alocal risk assessment has been completed. Thecovers may be too heavy and the engineers’standard tools may not be suitable. They couldput themselves and the public at risk byattempting to lift the covers without theappropriate tools.
If you are unsure about the frame and cover to beused, please contact your newSites representativefor guidance.
The preferred supplier is Salmor IndustriesLimited. For information, go to: www.salmor.co.uk

Pre-formed chamber system
A pre-formed chamber system, producedby Salmor Industries Ltd. has beenapproved by Openreach for use bydevelopers.
Developers have the option to choose this de-skilled, fast-track method of construction whichdoes away with the need for specialist box buildingteams and concrete backfill. Complete chamberscan be constructed from excavation toreinstatement in little more than an hour.
Known as the Quadbox, the system comes instandard 150mm deep structural twin wall ringsections providing maximum flexibility andstrength. Joint box Modular Footways (JMF) 102, 104 and 106 are the Openreach approvedversions. A 150mm concrete base has to beprovided clean and level.
Box furniture items slot into moulded pocketswithin the chamber doing away with therequirement to cast-in fixings or to drill on site.Duct entries are also easy to achieve using astandard hole saw mounted on a cordless drill.
The Quadbox’s modular design makes it perfectfor overbuilding on existing ducted networks.Existing cables can be managed through thechamber walls and duct entries can be cut in anylocation. Chambers can also be benched to avoidexisting services.
As well as saving time and skilled labour, this pre-formed system also has numerous health andsafety benefits.
The Quadbox does not form part of Openreach’sfree stores listing available to developers. It willneed to be purchased direct from themanufacturer.

New External Termination Point (NTE)
Openreach has introduced a New External Termination Point (NTE) to be fitted on theoutside of all new houses for telecommunications services from September 2007.This is now the demarcation point between Openreach’s external network and thedeveloper/customer-provided wiring.
All internal wires and sockets beyond theexternal NTE will be the responsibility ofthe builder/customer, unless installedand commissioned by OpenreachEngineers. Developers should ensure thattheir electricians terminate the relevant cables to the correct terminals, using the2, 3, 5 IDC connector, within the externalNTE and identify the positions of anyinternal telephone sockets to thehomeowner. It is important to informyour Openreach Newsite Representativewhen plots are ready for connection inorder to avoid delays in service provision
Installation
Lay Openreach grey duct from the footway jointbox (with the socket end presented to the jointbox) and terminate with a pre-formed 90° bendat the outside of the house wall. Keep duct runsto a minimum depth of cover of 350mm beneaththe proposed finish level (450mm under asoft surface).
Supply and install standard 20mm electricalconduit through the cavity wall at a point verticallyabove the end of the service duct.
All duct is to be provided with a lead-in cable afterinstallation. Leave one metre at the house andthree metre tails in the chamber.
Service duct should be cut level, two bricksbelow damp proof course and should be sealed atboth ends using Duct Plug 1A, to prevent ingressof debris.
External capping 25 and Connector Bend 4 to befitted as required.

(See diagram on page 23)
Developers benefit because:No need to supply and fit backbox for NTE5a.
All internal sockets are provided by thedeveloper and can be of any design conformingto BS Standard.
Openreach or its sub-contractors will no longerrequire access to properties for the installation.So there will be no more asking for keys etc andeliminates the risk of soiling or damage torecently completed interiors.
Developers should ensure that the internalextension wiring is planned to emerge through the outer wall and is terminated on the customerwiring side of the New External Termination Point (NTE).
Multi-occupancy buildings (i.e. flats/apartments)will continue to use the existing NTE5a within theproperty for now but Openreach is looking atfurther External NTE/Line Module options.
22 23
A number of options are available for cable entry into industrial units. An appropriatemethod of entry will have been agreed between Openreach and the site developer at theinitial design stage. Any subsequent revision which may be required should always beagreed with Openreach before execution.
The following are instructions for the installation of telephony supply into residentialflats, apartments and business properties. Should you require additional informationplease consult your Openreach newSites team who will advise you.
Each Individual Flat must be provided with its own cable from the main entry point or asagreed at the initial site meeting/proposal stage. The cables to each flat remain the propertyof Openreach and should be terminated on an Openreach Master NTE. This NTE should beplaced in an accessible position for maintenance and service purposes. If the Openreach NTE is not acceptable to you, please discuss the matter with your Newsite representative as otherarrangements can be made i.e. wiring as extensions from the master socket. Despite otherarrangements being available the first NTE in the flat must be an Openreach one in an accessible location.
Entry into flats and business properties
Installation
Lay 50mm or 90mm internal diameter grey ductfrom the footway joint box with the socket endpresented to the joint box and terminate with a90° pre-formed bend at the inside of the site wall.Keep duct runs to a depth of 350mm/450mmbeneath the proposed external ground level.(Please refer to Installation Guide on Joint Boxesand External Work and Installation Guide onDucting for more information).
For new buildings the section of duct which passesthrough the wall/floor is to be coated with SolventCement Compound 21 and then a dry 3:1sand/cement mixture. Any joints inside a buildingshould also be coated with Solvent CementCompound 21.
Wiring within cavity walls should be installedwithin 20mm conduit to ensure hassle freemaintenance.
Materials available from Openreach
50mm internal diameter PVC duct, includingpre-formed bends and tees (Duct No 56).90mm internal diameter PVC duct, includingpre-formed bends and tees (Duct No 54D).Plugs Pressure.Draw Cord.Solvent Cement Compound 21.
(See diagram opposite)
ImportantIt is the developer’s responsibility to ensure that all duct seals on site have beeninstalled correctly. Seal ducts as follows. Tie drawrope in hole provided on plugspressure and insert plug pressure into end of duct and tighten. For 90mm ductuse Plugs Pressure 1 and for 50mm duct use plugs pressure 3 see p35. This is toprevent any ingress of water or gas into the property.
Note: It is important that the incoming duct is sited so that access can be madeat all times for service provision and maintenance.

Please note:Multi media sockets are not acceptable to Openreach and Openreach wiringshould not be terminated directly onto such a socket. In the event of thishappening and a fault occurring the offending socket will be removed andreplaced by a single Openreach socket. Charges will apply.
Installation
Extension cabling shall be run from the Back Boxof the proposed main socket or external NTE, with300mm left coiled within for connection to themain socket or external NTE. Extension socketsshall be mounted on single-gang flush steel boxesconforming to BS 4662:1970. Not more than twoextension cable terminations are permitted to anyOpenreach standard socket.
Extension sockets should be located close topower sockets to facilitate the use of PC modempoints and answering and facsimile machineswhich require both types of supply. However, adistance of not less than 50mm must bemaintained between telephone cables and powercables throughout. Where this is not practical theymust be separated by an acceptable divider ofrigid non-conducting material.

Detailed information on cable installation andseparation is given in the British Standard Code ofPractice BS6701 Part 1, particularly clause 6 andthe relevant sections of the latest IEE Regulationsfor Electrical Installation (Regulation 525 is ofparticular importance). Where not supported inconduit or trunking, cables must be cleated atintervals of not more than 300mm.
The wiring pattern for cabling may be either seriesor spur. Typical patterns are illustrated overleaf.
It is not the responsibility of Openreach to ensurecontinuity of the cabling unless commissioned todo so.
Installing additional telephone sockets as part of the overall building programme avoidsthe problem of exposed wiring and will enhance the appearance of the finished project.All internal cables/wiring should be run inside conduit to enable future maintenancewhich does not disturb finished surfaces.
The following is a guide for the connection of extension sockets that you may wish toinstall at the time of build or construction.
The provision of all internal wires beyond the first socket or external NTE will normally bethe responsibility of the builder/customer but, if you prefer, we can arrange for the workto be carried out and commissioned by an Openreach engineer at our normal installationrates (please contact your newSites representative for details).
Basic materials requiredThe following materials are not part of ourstandard provision for new housing developmentsand may be purchased locally.

Please note:The main socket or external NTE must be supplied by Openreach and remainsthe property of Openreach. If an external NTE is used, no internal main socketwill be provided by Openreach. All extension wiring beyond the main socket isowned by the customer/developer. The wiring and sockets must be of telephoneor data grade, the wire diameter must be between 0.4mm and 0.63mm andeither solid or multi-strand. Bell/Alarm wire is not suitable under anycircumstance. Any faults attended by Openreach, and proved to be due to the customers own equipment will be chargeable.

With people rapidly becoming accustomed toliving life in the communications fast lane, there isan increasing likelihood for occupiers to want theirproperty to come with inbuilt fibre opticcapability.
To meet this demand, Openreach will require the installation of blown fibre tubing on somemulti-occupancy developments. Developers will be requested to run tubing within the building to ensure adequate availability for all customers.
Diverse routingand blown fibre tubeinstallations
Openreach will require a wayleave (consent inwriting) to install, maintain, adjust, repair or alterOpenreach plant under or over the developmentfor the statutory purpose as defined in our Code ofPractice. The only exception is where the owner isthe person requiring the telephone service. In thatcase, the contract between Openreach and theowner is, in effect, the wayleave and givesOpenreach permission to install cables acrossthe land.
A wayleave must be obtained prior to installingany Openreach plant and is part of your contract.
Openreach currently has two UK offices dealingwith queries relating to wayleaves.
For enquiries relating to England, Scotlandand Wales, please ring 0800 581 525 (option4) or email [email protected] [email protected]
Even though this is an uncommon event, somegeographic locations are more susceptible tolightning strikes than others. We will, as a matterof course, now check out all new developmentswhilst in the planning and design stage. If yoursite is identified as being in an area of higher risk,you may need additional lightning protection andthis will be factored in during the build stage ofyour site.
As a precautionary measure we may ask you toprovide an earth wire to the Openreach Maindistribution point or run copper tape in the groundto the jointing chambers.
