9 1.4 Audience The content in this document is intended to be used by NBN Co staff and Delivery Partners during the construction of the NBN Co network. NBN Co Delivery Partners NBN Co Field Operations Staff NBN Co Architects and Network Designers NBN Co Quality Assurance staff 1.5 Assumptions and Limitations All information regarding the interconnection to the Telstra Copper Network is assumed until an official agreement is in place. 1.6 Australian Standards Document Owner and Link [1] AS / ACIF Australian Standards / Australian Communications Industry Forum [1] AS 3015 Australian / New Zealand Standard, Electrical installations Extra-low voltage d.c. power supplies and service earthing within public telecommunications networks AS 3015 Australian / New Zealand Standard, Electrical installations Extra-low voltage d.c. power supplies and service earthing within public telecommunications networks [2] AS / ACIF S009:2006 AS / ACIF S009:2006 Communications Alliance [3] AS / ACIF S008:2006 AS / ACIF S008:2006 Communications Alliance [4] AS / CA S009:2013 AS / CA S009:2013 Communications Alliance [5] AS / NZ 3015:2004 AS 3015 Australian / New Zealand Standard, Electrical installations Extra-low voltage d.c. power supplies and service earthing within public telecommunications networks [6] AS 3000 Australian Standard 1.7 Related Documents Document [7] NBN-COO-EDS-350 NBN Co Construction Standards - DFN [8] NBN-TE-CTO-1756 Service Drop Installation Guideline [9] NBN-TE-CTO-1707 Passive Premises Labelling Instruction Owner and Link NBN-COO-EDS-350 NBN-TE-CTO-1756 NBN-TE-CTO-1707 NBN Co Limited Uncontrolled when printed Page 9 of 28

10 Document [10] NBN-NTO-EDS-390 NBN Co Construction Standard - Labelling Owner and Link NBN-NTO-EDS Before You Start NBN Co takes health, safety and environment very seriously, and expects the same of our Delivery Partners. The site design itself, and the information throughout this document, has been prepared to minimise Health Safety and Environment (HSE) risks, however many risks still require attention and control during construction. A number of these key risks and control measures are summarised below for your consideration. Note: This information is provided to assist in your risk management process (e.g. risk assessment, SWMS, JSEA etc.). It is not exhaustive. You must review these hazards and determine their relevance and, if appropriate, manage the risk via your Delivery Partner s approved risk management process and HSE systems, which should define specific risk controls, training requirements, and refer to relevant legislation, codes of practice and industry information. Contact with underground or hidden assets Falls from heights Asbestos Use of plant, tools and equipment FTTB buildings may contain underground gas, electrical, water, sewage, or telecommunications assets. These services can also be hidden in walls, cavities and slabs within the building. Contact with these may result in electrocution, fire, environmental impact or disruption to end-users. Consider the location, identification and avoidance of these when planning work. Dial Before You Dig (DBYD) plans often do not identify services beyond the property boundary, so consider a range of identification methods. Selecting of the appropriate equipment for and method of excavation / building penetration may also minimise the risk of damage. Consider your emergency preparedness in the event of damage. Some FTTB construction work may involve work at heights (e.g. cabling lead-in or earth). Consider means to eliminate or minimise work at heights, such as selection of a suitable platform or ladder for the task and the work area. Asbestos may be present in older FTTB sites, in a range of materials such as fibre cement sheet and pipe lagging. Consider identification of potential asbestos materials and avoiding disturbance of these. FTTB construction may involve the use of a range of plant, tools and equipment, such as excavators, concrete saws, and powered drills. Consider how you select these to be suitable for the task, and how the residual risks (e.g. overturning, striking another person / object, noise, dust, use of electricity) will be appropriately controlled.

11 2 Construct Fibre to the Building This document shall provide deployment standards including installation and commissioning requirements covering FTTB deployment. Any installation works completed shall be in accordance with the Building Code of Australia. This section details the Construction Standards for the elements that are required specifically for FTTB to connect the equipment in the building to the DFN / LFN.

12 3 Install the Required Equipment in the Building Any installation works completed shall be in accordance with the Building Code of Australia. The FTTB equipment shall be standard across all builds. The FTTB Cabinet shall come in a single size rack. FTTB racks are pre-staged with most internal equipment pre-installed. LT (Line Terminal) cards are allocated to site according to services demand as per Table 1. Card Allocation. Table 1. Card Allocation Quantity of LT cards allocated Maximum subscriber capacity Maximum Designed Serviceable Locations Multiple racks may be installed in an MPS to achieve greater capacity, provided that the internal building copper pathways: a. shall not cross over b. shall not run in parallel with one another 3.1 Lead-In Conduits In line with the NBN Co guiding principles, the expectation is that the majority of underground Service Drops will be successfully completed by utilising existing Telstra lead-in conduits (LICs). Existing available infrastructure that conforms to standard shall be used, rather than create new infrastructure. If there is sufficient room in the existing conduit it shall be used. If one or more Telstra LICs can be found at a premises, the delivery partner / contractors shall use the Telstra LIC in accordance with the rules in [8] NBN-TE-CTO-1756 Service Drop Installation Guideline. NBN Co Limited Uncontrolled when printed Page 12 of 28

13 Note: Any existing cable in situ as a pull through device shall not be used. Any existing cable or hardware shall not be disconnected. Any existing cables shall not be damaged. Any services over existing cables or equipment in the Telstra LIC shall not be disrupted. 3.2 New Lead-in Conduit Requirements Where Lead-in/Building entries apply a minimum P50 lead-in in conduit shall be provided from the boundary pit to the MDU for any new lead in conduit installations. The following guidelines apply as minimum requirements for new lead-in conduit installations: a. Where up to 6-48 fibres are required (typically up to 30 premises), NBN Co requires 1 white 52mm (nominal internal diameter) PVC conduit with a minimum wall thickness of 3.45mm. b. Where fibres are required (typically premises), NBN Co requires 1 x white 52mm (nominal internal diameter) PVC conduit with a minimum wall thickness of 3.45mm. c. Where more than 100 fibres are required (typically greater than 61 premises), NBN Co requires a minimum of 1 x P100 telecommunications conduit. d. Cable bend radius must not be exceeded in looped cables (as per manufacturer s specifications) and no excess tension due to cable radius. Figure 7. Cable bend radius e. Maintenance loops as per NBN Co design rules i.e. every 1km of fibre and change of direction between 90 and 270 degrees exclusive. Figure 8. Cable Maintenance Loops NBN Co Limited Uncontrolled when printed Page 13 of 28
