1 For business Wiring your business for broadband Your cabling requirements are dependent on the size and complexity of your business. Smaller businesses should follow the wiring recommendations for residential properties. Larger businesses should contact a structured cable specialist to design and deliver a tailored solution. The cabling requirements of your business will be dependent on: Number of staff and what type of connectivity is required How you deliver voice services Data requirements A well designed structured cable solution will take into account the technical requirements of the business and will include computer cabling, voice requirements, outlets, repairs, maintenance and fault finding. Installation tends to be simplier than residential properties due to the nature of commercial buildings, with ceiling panels and a cable backbone part of many complexes. Keep in mind that if you want to connect your business to our new Ultra-fast broadband network and you are in a multi-story building you will need consent from the building owner. What happens when copper is required? Within a UFB fibre area there may be commercial requirement for copper to be deployed to a new building/development for a particular network service required by a business. In these instances, we will evaluate the deployment of copper on a case-by-case basis, taking into account the particular business need. We believe that the demand for copper network will decline over time as telecommunications service provider offer more sophisticated services over our new fibre network. If you do require copper we will put together a specific network design and a quote on the costs of the specific lead-in and cabling requirements. We can undertake this work for you.

2 Installing underground lead-in pipes Our network is typically built up to the boundary of the property. A lead-in pipe is needed to get the network cable from the point on the boundary where our network terminates (the network terminal) to the point on the building where the internal cabling needs to connect to our network (known as the external termination point or ETP). The lead-in is the property owner's responsibility and can be installed by an electrician or builder. A lead-in pipe is required in all property developments whether it's a single level residential dwelling or multi-story office or apartment block. These will be different sizes and locations depending on the scale of the property. There are three components to an underground lead-in: If you don't comply with this information, you run the risk of a refusal to connect your premises to the network and will be required to meet the cost of rectifying any sub-standard installation. 1. Lead-in pipe with associated pre-formed bends. This protects the cable and makes it easier to replace or add cable: The lead-in pipe should be a minimum of 20mm internal diameter and should be telecommunications green in colour which can be purchased from electrical wholesalers. 2. Lead-in cable. We require a draw tape rather than cable is installed. There are different cable choices including copper, fibre or hybrid. We'll use the draw tape to install the correct cable for the property. 3. External Termination Point (ETP) to house the connection point between the inside and outside cabling. The ETP should be positioned as close as possible to the front of the building at a minimum height of 300mm above finished ground level with a maximum height of 1500mm. We'll provide and install the correct ETP. Ideal lead-in duct layout Trenching Trenching can be done by open trenching, direct drilling or thrusting methods. You can save unnecessary work and cost by following these basic requirements: If you're unsure about trenching requirements, please contact us on Get local council permission if trenching public footpaths/roads is required. Check the location of existing power/telecommunications and other underground networks before digging by visiting the beforeudig website. Special conditions may apply if any network is present. Clearly find the network terminal point in the street and the ETP location at your property BEFORE selecting the trench route and digging. Contact

3 your broadband provider or us where there's no terminal or you're unsure where it is. The trench should be as straight as practicable avoiding sudden changes in direction or elevation. Trench depth should be 450mm below finished ground level. Where the lead-in will be under permanent material (e.g. concrete driveway) the depth can be reduced to 300mm. Take extra care when digging within 500mm of a network terminal point. Urban lead-in installation Rural lead-in installation The only difference between urban and rural lead-ins is that some of the cable may be direct buried on a rural property. The cable should be carried in a

4 pipe under high traffic areas directly around the house or driveway and can be direct buried to the road. The maximum ducting distance is around 30m. " If our cables are damaged, call NETWORK ( ) immediately. " Installation The green telecommunications pipe is laid when the builder/developer has the services trench open and can be laid by the builder or electrician. If you find part of our network (pole, cable or cable terminal) needs to be moved/removed for the development to proceed, please contact us on NETWORK ( ). Things to remember: The lead-in cable must be installed in a lead-in pipe - except in rural areas where, depending on the distance of the house from the road, some of the lead-in may be direct buried. Each residence must have an individual lead-in from the network access point to the ETP. The ETP must be a minimum of 300mm above the finished ground level but no more than 1500mm above ground. Access to and terminating at a network terminal is Chorus' responsibility. Telecommunications cables must leave buildings through their own conduit and this must not be shared with power cables. A lead-in cable can share a trench with other services, but requirements for clearances must be met as shown below. Plan view of a lead-in installation (urban) Individual lead-in pipes to each living unit e.g. flat, house etc. Lead-in pipes are to be kept as straight as practicable. The ETP is the connection point for internal to external wiring.

5 Clearances Power: See the table below Gas pipelines: (Pressures Kpa) Crossings: 300mm minimum Parallel: 450mm minimum Sewer, Stormwater, Water etc: 150mm minimum If you're unsure about a type of power cable, contact your power or gas company or sewer and water pipes, contact your council. Power cable voltage Power cable type With mechanical protection installed Minimum separation Low voltage - exceeding 50V AC or 120V ripple free DC, but not exceeding 1000V AC or 1500V DC Natural screened or armoured No 150mm crossing 300mm parallel Yes 50mm Other than neutral Screen or armoured No Yes 450mm 50mm crossing 450mm parallel High voltage - any volatage exceeding 1000V AC or 15000V DC Single or multicore No 450mm Yes 150mm crossing 450mm parallel (2.4km max parallel length) Mechanical protection Mechanical protection is installed to protect the power cable or gas pipe from any future digging activity. Examples are: 50mm thick (or greater) concrete slab. 25mm thick (or greater) ground contact treated timber. Tough plastic slab of minimum dimensions 10mm thick x 150mm wide x 750mm long. Please note: 1. Mechanical protection shall be positioned to give maximum protection to the power cable or gas line from any digging activity. 2. Refer to the table above for the power line clearances.
