6 3.2. What is Telstra Velocity? Telstra Velocity is Telstra s state-of-the art Fibre-To-The-Premises (FTTP) network. Telstra uses FTTP technology to supply telecommunications services to the residents of Telstra Smart Communities, which may include high-density developments such as town houses, villas and high-rise apartments. With Telstra Velocity, telecommunications services are supplied to the home via a single optical fibre instead of copper twisted-pair cable or coaxial cable. The optical fibre cable that runs to the home is similar in physical size to a conventional cable but contains no metallic components. Also, only one such cable is necessary to supply telephone, Internet and TV services, instead of two or more separate cables What services does Telstra Velocity provide? Telstra Velocity can supply the following services: up to four (4) telephone services; a BigPond broadband Internet service; digital free-to-air (FTA) TV; and a Foxtel* digital pay TV service. Each telephone service will support narrowband dial-up modems and most dial-up alarm units (e.g. monitored security alarm and medical alert systems). The broadband Internet service does not require a modem and may be connected directly to the Ethernet port of a personal computer or an Ethernet router/switch. Notes: 1. Cable modems designed for connection to Telstra s HFC network (BigPond Cable) will not work over the TV service cabling broadband Internet access is provided via the broadband Internet service described above. 2. Payphones and ISDN are not supported by Telstra Velocity. The digital FTA TV and Foxtel Digital pay TV services provided by Telstra Velocity avoid the need for an external TV antenna or satellite dish What equipment is required at the customer s premises? Network termination equipment The optical fibre lead-in cable from the street terminates within a device that converts the optical (light) signals into electrical signals. This device is called an optical network termination (ONT). The ONT has two compartments the Telstra compartment and the cabler compartment. Non-Telstra cablers are not permitted to access the Telstra compartment but will need to access the cabler compartment to connect the telephone, broadband Internet and TV cables. The ONT is installed on the external wall of the building by Telstra. In the case of high-rise apartments, the ONT will usually be installed inside the customer s unit.

7 (a) ONT within a combined enclosure with the electricity (b) Stand-alone ONT Notes: 1. It is recommended that the ONT be installed in a combined utilities enclosure (CUE) with the electrical power to simplify installation, for greater weather protection and to provide a neater appearance (see Figure 5). The CUE must be provided by the builder s electrician as part of the electrical installation. 2. For more information about the Telstra ONT, refer to section 4. Figure 1 Telstra ONT Power supply A power supply unit (PSU) is required in the customer s building to provide power for the ONT. This requires a 240 V socket-outlet into which the PSU cord is plugged. Telstra installs the PSU. The builder or customer provides the 240 V socket-outlet to power it.

8 Figure 2 Telstra PSU Optional battery The PSU may house a rechargeable battery, provided by the customer, to ensure continuity of telephone services during a power outage. A battery should be fitted if a monitored ( back-to-base ) security alarm system or a medical alert system is to be installed. Note: Powered customer equipment such as cordless telephones and VOIP equipment will not operate during power failure unless they too have battery back-up. More information about the optional battery is provided on the Telstra Smart Community website (look under My Builder ). Figure 3 Optional PSU battery Document No Copyright Page 8 of 92

9 4. INSTALLATION OF THE TELSTRA ONT 4.1. ONT dimensions Typical ONT installations are shown in Figure 1. The ONT dimensions and the space required for it are shown in Figure 4. A minimum space of 400W x 415H x 140D (in mm) is required for the ONT, which includes clearances for access, cable entry and ventilation. The critical clearances are as follows: 65 mm is required on the left side of the ONT (measured from the left edge of the cover hinge) to provide room to open the hinged cover. 50 mm (100 mm preferred) is required at the bottom of the ONT (measured from the lowest extremity of the ONT) to provide space for cable entry. 20 mm is required at the top of the ONT to provide clearance for opening the cover. 30 mm is required on the right side of the ONT (measured from the right edge of the securing bolt carrier) to provide room for accessing the cover securing screws and clips. 30 mm is required in front of the ONT (measured from the highest point on the closed cover) for ventilation purposes. Any enclosure housing the ONT should be vented Mounting tab TELCO Telstra access Cabler access NTD Property of Telstra N (Cable entry at bottom only) Mounting tab Front Side Note: The Telstra ONT has been designated as a Network Termination Device (NTD) and is Telstra s network boundary. This means that the cabling connected to the cabler access side of the ONT is customer cabling and is subject to the requirements of the ACMA Wiring Rules (AS/ACIF S009).

10 4.2. ONT location Single dwellings, town houses, terrace houses and villas With detached and semi-detached dwellings, the ONT must be located on an external wall, preferably in a combined enclosure with the electricity. See Figure 5. Where a combined enclosure is not provided by the builder s electrician, the ONT should be installed below the electricity enclosure to ensure accessibility and to avoid problems with fences, downpipes and the like. However, if it is not possible to locate the ONT below the electricity enclosure (e.g. due to a gas meter, water meter or water tap), the ONT may be mounted to one side of the electricity enclosure. The ONT must be located at least 300 mm away from any gas meter, water meter or water tap. Electricity compartment Earthing terminal (CET) Earthing conductor Telstra ONT Telecommunications compartment (shown with cover removed) Electrical earth electrode (typical) Notes: 1. The equipotential bonding conductor for the CET (Communications Earth Terminal) must be installed by the electrician. The CET may be installed by either the electrician or the Telstra installer. See for more details. 2. For Telstra s combined enclosure requirements, refer to For details about lead-in conduit positioning, see Figures 8 and 9. For details about conduit positioning for the internal cables, refer to Figures 14 and 15.

All measurements are in mm. 2. The recommended position for the Telstra ONT is under the electricity enclosure. However, the ONT may be positioned to one side of the electricity enclosure if necessary. The ONT must be located at least 300 mm away from any gas meter, water meter or water tap. 3. For details about lead-in conduit positioning in the building footings, see Figures 8 and 10. For details about conduit positioning for the internal cables, refer to Figures 16 to Where the electrical earth electrode is near the Telstra ONT and is accessible, the ONT may be earthed to this electrode. The earthing conductor connection to the earth electrode will be labelled either Telstra or Telecommunications Bonding Conductor. Where the electrical earth electrode is not located near the Telstra ONT or is not accessible, it will be necessary for the electrician to provide an earthing conductor for the ONT (see 5.2.6). The earthing conductor should be taped or tied to the lead-in conduit or, alternatively, it may be taped or tied to the conduit for the internal cabling if expedient. The lead-in conduit must not be drilled under any circumstances, as this may allow the entry of water or termites to the wall cavity via the underground lead-in conduit. 5. The Telstra installer will use flexible conduit to make the final lead-in and PSU cable connection to the ONT.

For more details about lead-in conduit positioning, see Figures 8, 10 and 11. For details about conduit positioning for the internal cables, refer to Figures 16 and Where the electrical earth electrode is near the Telstra ONT and is accessible, the ONT may be earthed to this electrode. The earthing conductor connection to the earth electrode will be labelled either Telstra or Telecommunications Bonding Conductor. Where the electrical earth electrode is not located near the Telstra ONT or is not accessible, it will be necessary for the electrician to provide an earthing conductor for the ONT (see 5.2.6), in which case the earthing conductor should be taped or tied to the conduit for the internal cabling. It may enter the same port as the internal cabling and will be connected on the Telstra side of the ONT by Telstra. 5. The Telstra installer will use flexible conduit to make the final lead-in and PSU cable connection to the ONT.

13 Where there is no external electricity enclosure at the building Where an external electricity enclosure is not, or will not be, installed at the house or dwelling unit, the Telstra ONT must be located on the external wall of the house/unit at a convenient and readily accessible location and, as far as practicable, in accordance with the following requirements: on the same side of the building as the Telstra property entry point; and as close as possible to the electrical switchboard (presumably located within the building) to facilitate earthing of the ONT. In such cases, the builder s electrician is required to provide a suitable earthing conductor for the Telstra ONT. See for more details. For technical and safety reasons, the ONT must not and will not be installed at any building or structure detached from the house or dwelling unit (such as a separate garage or fence) Multiple dwelling units (MDUs) With multiple dwelling units (MDUs), the Telstra ONTs must be located at the individual units and must not be located collectively in a common area. Guidelines for cabling of MDUs for Telstra Velocity are provided in section 7. Where the ONT is installed inside the building, at least 900W x 900D (in mm) clear floor space is required in front of the ONT for access purposes. Refer to 4.1 for the wall clearances required around the ONT for ventilation and opening the ONT cover Combined enclosure requirements Telstra s requirements for combined utilities enclosures (CUEs) are set out in Telstra Specification The essential Telstra requirements for CUEs are as follows: (a) The minimum internal dimensions of the space in which the ONT is to be housed must be 400W x 415H x140 D (in mm). (b) The telecommunications compartment door aperture must be at least 375W x 375H (in mm). (c) A backboard of insulating material (e.g. timber) that is at least 400 mm wide and 18 mm thick must be provided for mounting of the Telstra equipment and must extend at least 350 mm below the horizontal plane of the top edge of the door aperture. (d) A sturdy metal plate must be provided over any electrical conduits or cables that run behind the telecommunications backboard. A minimum clearance of 20 mm must be provided between the metal plate and the rear of the backboard for the passage of cables. (e) Suitable cable entry facilities or knock-outs must be provided and must be accessible within the telecommunications compartment. External combined electricity and telecommunications enclosures that are suitable for housing the ONT are available from B&R Enclosures ( ). Approved enclosures are listed in Telstra Document No A03, Information for Builders Cable entry facilities for Telstra Velocity networks. In the case of multi-storey MDUs where the ONT must be located inside the building, the ONT may be installed in the same enclosure as the PSU and the home distributor (see and 7.3.3).

14 4.3. Building entry conduit arrangements The importance of the building entry conduits Building entry conduits provide: a duct for pulling in cables; physical protection for the cables during building construction; and the required physical separation between the telecommunications cables and electrical power cables within the wall cavity. The integrity of the building entry conduits is very important to ensure that cables can be drawn through them. In particular, the conduit used to pull in the optical fibre lead-in cable must be capable of passing a pre-terminated optical fibre connector without damage. Within the building footings and any building cavity, only rigid conduit with a minimum inside diameter (ID) of 23 mm (e.g. Telstra P20 conduit) may be used, with no more than one 300 mm radius bend in the ground and no more than one 100 mm radius bend above ground or within the wall cavity. Flexible conduit with a minimum outside diameter (OD) of 25 mm may be used on the external wall only to protect the cable between the ONT and where the rigid conduit terminates on the external wall. Telstra will install any lead-in conduit required on the external wall Lead-in conduit in the building footings Conduit for underground lead-in cabling should be installed in the building footings before the concrete is poured. A conduit/bend assembly as shown in Figure 8 should be located in the building footings in accordance with Figure 9 or 10. See also Figures 14 to 18. Telstra will install this conduit before the footings are poured if possible. However, if Telstra is unable to meet the builder s timetable, the builder or electrician should install it. Otherwise, Telstra will install conduit over the footings later, but it will necessarily protrude significantly from the wall (see Figure 11). Conduit installed in the building footings for Telstra lead-in cabling must be white 20 mm (ID) Telstra conduit, Telstra part no. 73/91 (20 mm is the nominal inside diameter the actual inside diameter is 23 mm). A 300 mm radius bend, Telstra part no. 73/271, must be used for the bend. Note: Telstra conduits and bends are generally available from electrical suppliers, and are marked Telstra. Do not use any conduit or bend that is not marked Telstra even if it looks suitable some bends available are too sharp or the bend is constricted (e.g. oval shaped). Orange conduit or any conduit marked ELECTRICAL must not be used for any Telstra cabling whether or not it will be covered by concrete. The conduit in the ground adjacent to the building must be installed to a minimum depth of 300 mm and a maximum depth of 500 mm from finished ground level (FGL). Document No Copyright Page 14 of 92

The conduit must be white Telstra 20 mm conduit, Telstra part no. 73/91. Suitable lengths of conduit must be glued with solvent cement to a 300 mm radius bend, Telstra part no. 73/271. The ends of the conduit must be capped, plugged or taped to prevent the ingress of debris or silt. 2. The underground part of the conduit must be positioned at a minimum depth of 300 mm and a maximum depth of 500 mm from FGL, and pointed in the direction of the Telstra property entry point if not already joined to the Telstra lead-in conduit.

The conduit may enter the building footings from any direction as long as it is pointed in the general direction of the Telstra property entry point. 2. The vertical section of the Telstra lead-in conduit must be positioned to enter the bottom of the enclosure without the use of flexible conduit. The electrical conduit must run through the telecommunications compartment under the metal shroud provided for the purpose.

18 Part of 300 mm radius bend (<45 ) Part of 300 mm radius bend (<45 ) Full 300 mm radius bend Notes: 1. Telstra will install the conduit this way if it has not been installed in the building footings (or if it has been installed in the footings but is not useable). 2. With this arrangement, the conduit will usually protrude from the wall for some distance above finished ground level, as indicated in the diagram at left. Some builders may actually prefer that the conduit be installed this way over the termite barrier. Figure 11 Telstra lead-in conduit contoured over the building footings Surface lead-in conduit arrangement for an internal ONT (some MDUs) Where an external ONT cannot be installed (e.g. some MDUs), Telstra may stipulate that the ONT be installed inside the building. In such cases, the lead-in conduit should terminate on the external surface of the building at least 500 mm above finished ground level. A conduit must be provided within the wall between the end of the external conduit and the ONT location (see Figure 12) unless the ONT is to be installed on the internal wall just above the cable entry point as shown in Figure 13. The underground lead-in conduit must not be concealed in the wall cavity in such cases unless the conduit terminates on the external wall. Conduit terminating inside a wall cavity will not be accessible after building completion and carries a high risk of water or termite entry via the conduit. Document No Copyright Page 18 of 92

(Note) FGL Note: The conduit must run at least 500 mm above finished ground level (FGL) so that it may be flexed away from the wall at the building entry hole to aid drawing in the cable. A small amount of conduit movement will also be possible after the installation is completed to enable inspection of the building entry point for termite activity by a qualified pest inspector.

21 Conduit to the roof space or cable distribution point A conduit should be provided between the Telstra ONT and accessible roof space (see Figures 14 to 17) or directly to the cable distribution point and PSU if they are located on the internal side of the same wall on which the ONT is located. This conduit will: correctly position the cables at the ONT location where a combined enclosure is not used (see Figure 18); protect the cables from damage during construction; help to ensure the cables are not dislocated or entombed in the external wall cavity during construction; assist replacement of any damaged cables or installation of additional cables; and ensure the required cable separation requirements of the telecommunications and electrical wiring rules are met. 20 mm Telstra conduit, Telstra part no. 73/91, should be used for this purpose. The inside diameter (ID) of this conduit is actually 23 mm. AS/NZS 2053 conduit ( electrical conduit) is measured by outside diameter (OD) and is either too small to accommodate the cables (25 mm OD conduit is only 20 mm ID) or too big to comfortably fit into the wall cavity (32 mm OD conduit is the next size up). Note: The above conduit installed in accordance with this document should accommodate two PVC-sheathed 4-pair, category 5 cables, one RG6 coaxial cable and the PSU cable, for connection at an internal distribution point such as a home distributor, as described in section 6. Orange conduit must not be used for any telecommunications cabling. The telecommunications conduit should be installed in accordance with the following requirements: There should be no more than two (2) bends in the conduit between the internal access point (e.g. accessible roof space) and the conduit access point on the external wall. In the case of a 2-storey building, the conduit should run all the way to the roof space (where it can be accessed after building completion), not to the ceiling cavity of the lower floor unless the conduit runs to a cable distribution point on the internal side of the same wall on which the ONT is located. Flexible conduit should not be used in building cavities due to the difficulty in drawing cables through such conduit. Conduit bends should have a bend radius of 100 mm or greater (a bend radius of 300 mm is recommended for the upper bend into the roof cavity). Note: Suitable bends are Telstra part no. 73/281 (100 mm bend radius) and Telstra part no. 73/271 (300 mm bend radius). Document No Copyright Page 21 of 92

Glue all conduit and bend joints so that the fittings will not come apart when cables are being drawn through them. 3. A 6 mm² green/yellow equipotential bonding conductor must be run to either the main earthing bar of the electrical switchboard (see 5.2.6) or the electrical earth electrode as shown. In the latter case, this conductor should be taped to the lead-in conduit. The earthing conductor does not need to be installed in conduit within the wall cavity. The bonding conductor will be terminated on the ONT by Telstra. Figure 14 Typical entry conduits for the ONT where a combined enclosure is used, side view Document No Copyright Page 22 of 92

If possible, run the conduit to the roof space at an angle so that: a 300 mm radius bend at the top will fit comfortably between the top plate and the roof battens; the cable will be clear of the power cables from the electrical enclosure in the roof space; and the cable will be more accessible from the roof space after building completion. Alternatively, the conduit may run directly to the internal cable distribution point (e.g. home distributor) and the PSU if they are to be located on the internal side of the same wall on which the ONT is located. 2. Where it is not possible to run the conduit at an angle, run it vertically beside or behind the electricity enclosure. Ensure that the telecommunications cables are separated from the power cables in accordance with the wiring rules.

If possible, run the conduit to the roof space at an angle so that: a 300 mm radius bend at the top will fit comfortably between the top plate and the roof battens; the cable will be clear of the power cables from the electrical enclosure in the roof space; and the cable will be more accessible from the roof space after building completion. Alternatively, the conduit may run directly to the internal cable distribution point (e.g. home distributor) and the PSU if they are to be located on the internal side of the same wall on which the ONT is located. 2. Where it is not possible to run the conduit at an angle, run it vertically beside or behind the electricity enclosure. Ensure that the telecommunications cables are separated from the power cables in accordance with the wiring rules. 3. Fix the horizontal section of each bend a multiple of the brick spacing above the brick base. For standard 230 x 110 x 76 clay bricks, this will be a multiple of 86 mm, e.g. 7 bricks x 86 = 602 mm (see Figure 18).

27 5. INSTALLATION OF EQUIPMENT AND CABLING 5.1. Who installs what? ONT and PSU The ONT, the PSU and the cable connecting them are Telstra equipment and are supplied by Telstra. However, the builder or customer must provide the 240 V socketoutlet required to power the PSU. The special PSU cable (or a conduit for this cable) should be installed by the builder s telecommunications cabling provider in conjunction with the customer cabling. Guidelines for location of the PSU and associated 240 V socket-outlet are provided in Earthing conductor for the Telstra ONT An earthing conductor is required to earth the Telstra ONT. The builder s electrician should install this earthing conductor. Refer to for details Telephone, Internet and TV outlet cabling Lead-in trench 5.2. PSU Description The Telstra ONT is designated as a Network Termination Device (NTD) and is the network boundary. Cabling between the ONT and the telephone, Internet and TV outlets is customer cabling and is to be provided by the builder s or customer s chosen cabler. Options and guidelines for installation of this cabling are provided in section 6. Notwithstanding anything contained in this Guideline, it is the cabler s responsibility to ensure that all materials used are ACMA compliant and that they are installed in accordance with the ACMA Wiring Rules. The builder must dig and reinstate the trench for Telstra s optical fibre lead-in cable. A shared trench with the electricity power mains is preferred. Telstra s requirements for the lead-in trench are set out in Telstra Document No A07, Information for Property Developers, Builders and Customers Telstra s lead-in trenching requirements (this document is available at under My Builder ). The PSU is pictured in Figure 2. PSU dimensions are shown in Figure 19. Note that these are subject to change and should only be used as a guide. The PSU provides the power for the Telstra ONT. It converts the domestic 240 V a.c. to 12 V d.c. to operate the electronics in the ONT. The PSU may house a sealed, rechargeable, lead-acid 12 V, 7.2 a.h. battery to maintain operation of the telephone lines for a limited time (nominally up to 8 hours) during blackouts. A typical battery is shown in Figure 3. More information about the optional battery is provided on the Telstra Smart Community website (look under My Builder ). Document No Copyright Page 27 of 92

28 Powershield 195 Cable entry Power cord entry Note: 240 Front The dimensions include the battery, where provided. The battery is housed inside the PSU (see Figure 3). 76 Side Figure 19 Telstra PSU dimensions V socket-outlet for PSU PSU location General Height Environment The PSU is wall-mounted and connected to the domestic power via a plug and cord (see Figure 2). A dedicated, standard 240 V socket-outlet is required within 1 metre of the PSU. A pilot light is not required on this outlet. The socket-outlet is to be provided by the builder or customer. While not essential, it is recommended that the PSU socket-outlet be connected via a separate final sub-circuit to ensure continuity of telecommunications services if a circuit breaker is tripped by another electrical appliance. The PSU should be located in a utility area of the building (e.g. the garage) within 25 m radial distance of the ONT, preferably next to the home distributor (see 6.1.5). The maximum permissible length of the PSU-ONT cable is 30 metres. The bottom of the PSU must be no more than 1700 mm and no less than 350 mm from the floor. A height of 1000 mm to 1300 mm is recommended. The PSU must not be located in a damp or dusty area or in any position exposed to direct sunlight. The PSU may be located in a robe or cupboard as long as adequate clearances are maintained around and in front of the PSU for access and ventilation. At least 50 mm of air space is required around and in front of the PSU for ventilation purposes. Any enclosure housing the PSU should also be vented. At least 900W x 900D (in mm) clear floor space is required in front of the PSU for access purposes. Additional guidelines for location of the PSU in certain areas of the home are provided in Table 1.

30 The cable is supplied by Telstra and may be installed by the builder s cabling provider in conjunction with the customer cabling. Alternatively, where the PSU will not be co-located with a home distributor, the builder may install conduit in accordance with and Figure 21 to enable this cable to be drawn in by Telstra s installer after building completion. Leave 500 mm to 600 mm of this cable on the external wall for connection within the ONT. The cable conductors and terminals must be protected during construction using a plastic bag that is tied or taped to the cable sheath. Refer to Figure 20. Wall End of conduit Insulation tape Plastic bag Terminals PSU cable 500 mm mm Figure 20 PSU cable at the ONT end Conduit for the PSU cable (optional) Where the PSU is co-located with the home distributor, the PSU cable will normally be installed with the customer cables between the ONT and the home distributor. However, a separate conduit should be provided for the PSU cable at the building frame stage if the PSU will not be located next to the home distributor. Conduit will normally only be required for the full length of the PSU cable if the cable is not available for pre-wiring or the cable is in danger of being damaged during building construction (see Figure 21). In such cases, the conduit should meet the following requirements: Use 20 mm ID Telstra conduit (Telstra part no. 73/91). Do not use orange conduit or flexible conduit. Use no more than three 90 bends between draw points. The bend radius of each bend must be 100 mm or more. The total length of cable between the ONT and the PSU must not exceed 30 metres. Install a stud bracket where the cable will exit the wall and terminate the conduit within the wall cavity about 100 mm above the bracket, as shown in Figure 21. Thread a 3 mm polypropylene, braided cord (or a 2-pair, 3-pair or 4-pair cable) through the conduit and bends during assembly, to be used as a draw wire for the special PSU cable. Glue all conduit and bend joints and ensure the conduit is restrained along its full length to prevent movement when drawing cable through it. Document No Copyright Page 30 of 92

See for PSU location requirements. 5. Flexible conduit will be used to protect the cable going up into the ONT on the external wall. Tape (but do not glue) flexible conduit to the 100 mm radius bend to protect the cable during building construction.

32 Earthing conductor for the Telstra ONT The Telstra ONT must be earthed for safety reasons and for remote testing purposes. Where the electrical earth electrode is near the Telstra ONT and is accessible, a 6 mm² green/yellow equipotential bonding conductor may be run between the ONT and the electrode and must be connected to the electrode by a separate earthing clip. The connection must be labelled Telecommunications Bonding Conductor or Telstra in accordance with the requirements of AS/NZS Otherwise, the builder s electrician is required to: provide a 6 mm² green/yellow equipotential bonding conductor between the earthing bar in the electrical switchboard and a Communications Earth Terminal (CET) in the communications compartment of the combined enclosure or, where a combined enclosure has not been provided, located near but not in the electrical switchboard (in accordance with Clause of AS/NZS 3000:2000); and where a combined enclosure is not used, run a 2.5 mm², 4 mm² or 6 mm² green/yellow earthing conductor from the CET to the ONT location. This arrangement is shown in Figure 22. The length of the equipotential bonding and earthing conductors is unimportant for the purpose of earthing the ONT, as this earth is provided for electrical safety reasons, not for lightning surge protection purposes. The earthing conductor need not be installed in conduit within the wall cavity. The earthing conductor must be tied or taped to either the lead-in conduit or the customer cabling conduit (the earthing conductor may enter either the left hand or the right hand cable entry port, whichever is more convenient). Electrical switchboard Tag (Note 1) Tag (Note 1) CET (Note 2) Earthing bar or terminal (Note 3) 6 mm² equipotential bonding conductor (Note 3) 2.5 mm², 4 mm² or 6 mm² earthing conductor (Note 4) Telstra ONT The earthing conductor may enter either side of the ONT (Note 4) Notes: 1. The bonding conductor must be labelled Telecommunications Bonding Conductor at the switchboard end and also at the CET end if the CET is not within sight of the electrical switchboard. 2. The CET should be located in the communications compartment of the combined enclosure or, where a combined enclosure has not been provided, it may be located in any readily accessible location external to the electrical switchboard preferably next to the switchboard. 3. A licensed electrician must make the bonding conductor connection inside the electrical switchboard. 4. The earthing conductor will be connected to the ONT by the Telstra installer.

33 6. CUSTOMER CABLING 6.1. General requirements Description Cabling practices Sufficient customer cabling must be installed by the customer s cabling provider to provide end-user access to the telephone, broadband Internet and TV services. Separate cables are required for connection of the telephone, Internet and TV services from the Telstra ONT: one 4-pair twisted pair cable for the telephone services one or two 4-pair twisted pair Ethernet cables for connection of broadband Internet (two cables are recommended for a possible future second service) one coaxial cable for the digital FTA TV and pay TV services. Only the above cables may be connected to the ONT. These cables may connect directly to individual outlets in the home or, where more outlets are required, they may connect to an internal distribution point from which the cables radiate to the required number of outlets. It is strongly recommended that a home distributor (HD) is used for the internal distribution point. An HD: enables common cabling to be used for distribution of the telephone and broadband Internet ( data ) services; improves flexibility by enabling end-users to make telephone and Internet connections to suit their particular needs and to change the connections as their needs change; and because of the above, enables a standard cabling system to be used without the need to know what the eventual occupant s specific requirements will be. The HD is described in more detail in Three levels of cabling are described in 6.2 and 6.3 that will ensure adequate access to current and future services, using an HD. The wall plates used to provide end-user access to telephone and Internet services are referred to as telecommunications outlets (TOs), while wall plates used for connection of TV equipment are called broadcast outlets (BOs). These are described in more detail later. General guidance for the installation of internal cabling will be provided in Telstra Document No , Cabling of Premises for Telstra Services Information for Consultants, Developers, Builders, Owners, Cablers and Customers. Refer to this document for general cabling information, including: location and height of telecommunications outlets mounting brackets for telecommunications outlet wall plates separation from electrical power and other services socket variations, connection arrangements and cable colour codes cable types wiring diagrams home networking.

34 Detailed practices for the installation of Category 5/Category 6 and coaxial cabling will be provided in Telstra Document No A09, Information for Cablers and Customers Broadband cabling guidelines. These documents may be downloaded from the Telstra Smart Community web site (look under the My Builder menu) Relevant Australian Standards The telecommunications cabling must be installed in accordance with the requirements of AS/ACIF S009, Installation requirements for customer cabling (ACMA Wiring Rules). The cabling should also comply with AS/NZS ISO/IEC 15018, Information technology Generic cabling for homes Installer qualifications The customer cabling must be installed by a registered cabling provider. This is a legal requirement. Registered cabling providers are issued with a registration card and a registration number that they are required to produce on request. Open registration is required to install a home distributor and the cabling connected to it. In addition, the installer should have a Structured Cabling endorsement (denoted by the letter S ) and a Coaxial Cabling endorsement (denoted by the letter C ) on the registration card to show that he or she is skilled in installing Category 5 or Category 6 cabling and coaxial cabling. These endorsements are not a legal requirement, however Home distributor (HD) Description The services from the Telstra ONT should be connected to a device inside the building called a home distributor (HD), sometimes described as a home networking box. The cables from the Telstra ONT are connected to the HD and cables radiate from the HD to telecommunications outlets (TOs) and broadcast outlets (BOs) located in various rooms. The HD contains a patch panel a panel of sockets that can be interconnected ( patched ) using plugs and cords. This allows a standard cabling system to be used for all homes such that end-users (building occupants) will be able to tailor the connections to meet their own needs using the patch panel. It also provides flexibility to support changes in technology without the need to engage a cabling provider to alter the cabling or to rewire the home. A basic HD and cabling system will enable the end-user to: connect a telephone service to any TO connect a broadband Internet service to any TO share a broadband Internet service among several personal computers (PCs) using an Ethernet router interconnect Ethernet devices, such as PCs, printers and network media players, using an Ethernet switch access digital free-to-air (FTA) TV at any BO access Foxtel Digital at any BO (Foxtel subscription required) test the telephone lines and the broadband Internet service at a single, readily accessible point (i.e. at the HD patch panel). Document No Copyright Page 34 of 92

35 The HD may comprise a proprietary home networking box or may be constructed in a suitable closet by the cabling provider using standard wall plates and sockets. Whichever type of HD is used, plenty of space should be provided for mounting the Telstra Velocity PSU and other equipment such as an Ethernet router and/or Ethernet switch, RF splitter/amplifier, surge protective power board and the power supplies required to power such equipment. Two examples of a basic HD are illustrated in Figure 23. (a) A proprietary home networking box with integral RF amplifier/splitter (b) A non-proprietary patch panel made using standard wall plates and sockets Note: While the HD is a distributor, it is not a main distribution frame (MDF) because the network boundary is at the Telstra ONT, which is designated as a network termination device (NTD). Therefore, the requirements of the ACMA Wiring Rules (AS/ACIF S009) for distributors apply to the HD but the requirements for MDFs do not. Figure 23 Basic home distributors Location of the HD The HD should be installed in a readily accessible location. It does not need to be located in the centre of the home unless the home is extraordinarily large such that any cable between the HD and a TO is likely to exceed a length of, say, 50 m. The HD should not be located within 1 m of likely sources of electromagnetic interference, such as: an electrical switchboard or electricity supply meters any fluorescent light an electrical transformer of any description an electric motor or generator (e.g. a ducted vacuum system motor or a fixed electric drill, grinder or saw) any area where an arc welder may be used an air-conditioning unit a refrigerator or freezer.

36 Space requirements Patch cords Telstra PSU Telstra ONT Power outlets Recommended locations for the HD are a garage, utility room, walk-in robe, study or hall closet. The HD should not be located on the external wall of the building or be recessed into the cavity of an external wall (the external wall cavity may be damp from time to time, which may lead to corrosion of the HD components). Sufficient space is required at the HD to provide: air circulation for the PSU (where co-located with the HD as recommended); the required separation distances between telecommunications and power cabling and sockets; room for mounting customer equipment and associated power supplies; and room to manipulate and accommodate the patch cords. Patch cords should be rated Category 5 or Category 6, as applicable, to match the category of the cable used. The cords should be straight through (not crossover ) type and should be no longer than 0.5 m. Two patch cords should be provided for each dual-socket TO connected to the HD, plus two spare cords. The Telstra PSU should be co-located with the HD to ensure ready access by the enduser for monitoring its condition and installing or changing the back-up battery. For more information about the PSU, refer to 5.2. In multiple dwelling units (MDUs) where the Telstra ONT must be installed inside the building (e.g. high-rise apartments), the ONT should be co-located with the HD and the Telstra PSU. See section 7 for more information. At least one 240 V power outlet should be provided within 1 m of the HD for powering of customer equipment such as an Ethernet router/switch or an RF amplifier. In addition, at least one 240 V power outlet must be provided within 1 m of the Telstra PSU, as described in 5.2.2, if the PSU is located next to the HD as recommended Telecommunications outlets Description A telecommunications outlet (TO) is a wall plate containing one or more 8-position 8-contact (8P8C) modular socket/s (commonly called RJ45 sockets) for connection of customer equipment such as telephones and personal computers. Each TO should have at least two 8P8C sockets that are colour-coded or marked in the same way as the corresponding sockets in the HD patch panel. At least two sockets are required in each room for simultaneous connection of a telephone and a personal computer. Each TO should be numbered, with corresponding numbering on the relevant sockets at the HD patch panel. A typical TO is shown in Figure 24. Document No Copyright Page 36 of 92

37 Figure 24 A TO with two colour-coded 8P8C ( RJ45 ) sockets Number of outlets Several TOs should be provided in separate rooms. They should be located next to the BOs described in to provide for interactive pay TV and for connection of Ethernet entertainment equipment such as network media players and Internet Protocol TV (IPTV). The addition of a separate TO is recommended for some rooms (e.g. kitchen/family, study, master bedroom) to provide additional connectivity, for example: Install a TO in the kitchen or family room for connection of a wallphone or cordless telephone base station. Install one or two additional TOs in any room that may be used as a study or home office for connection of additional equipment such as a fax machine and a network printer. Install an additional TO beside the bed in the master bedroom for connection of a telephone and a laptop/notebook computer. Install a TO in an open area of the home, such as the family, lounge or living room, to provide for wireless access to the home network (while a wireless Ethernet router/ switch may be located at the HD to provide wireless access, the internal walls will attenuate the radio signals, reducing the data speed).

The wireless access point should be placed as high as possible in the room, such as on the top of a china cabinet or wall unit. Figure 26 Providing wireless network access in the family/lounge/living room Cable type Each socket is individually cabled from the HD using 4-pair, unshielded twisted pair, Category 5 or Category 6 cable that complies with Australian Standard AS/NZS 3080 (ISO/IEC 11801), Telecommunications installations Generic cabling for commercial premises. This cable has solid conductors. Do not use any cable with stranded conductors for the TO cabling. The sockets should be rated at Category 5 or Category 6, as applicable, to match the cable rating. Notes: 1. The current Category 5 standard is equivalent to the old Category 5e standard. Cable manufactured to the current Category 5 standard may still be called or marked Category 5e. 2. Category 5 cable is rated at 100 MHz and should support Gigabit Ethernet (1 Gbps). Category 6 cable is rated at 250 MHz and may support future 10G Ethernet (10 Gbps). Category 6 cable and sockets are more expensive but may support future technologies that Category 5 won t. Category 7 cable and sockets may be used instead of Category 5 or Category 6 cable and sockets. However, Category 7 cabling is quite expensive and is difficult to justify for home cabling at this time. Note: Category 7 cabling is shielded and rated at 600 MHz. It may extend the useful life of the cabling system because it may support future applications that Category 5 or Category 6 cabling won t support but which are currently supported by coaxial cabling (e.g. broadband video) or which may be more economically supported by optical fibre in the future (e.g. 100 Gbps Ethernet).

40 Cable length The total length of cabling between the ONT and any TO must not exceed 100 m. This includes the cable from the ONT to the HD, the cable from the HD to the TO and the patch cord at the HD. This limit is not likely to be exceeded in most homes. Note: Cabling method This is a signalling limitation of the ONT and is not related to cable length limits specified in generic telecommunications cabling standards. TOs should be star wired (cabled individually) from the HD with a socket terminated at each end of the cable one at the TO and one at the patch panel. Refer to Figures 32 and 33. Use cables with different sheath colours, e.g. blue and grey for the TO sockets. Alternatively, mark the cable sheaths at each end, e.g. Blue and White for the corresponding socket colours. Do not use cable with red sheath, as red is normally associated with fire detection/ alarm systems. In addition, mark each pair of cables at each end in numerical sequence (i.e. 1, 2, 3, and so on). The TO wall plates and the corresponding patch panel sockets at the HD will eventually be numbered the same way so that the end-user will be able to readily identify them Cable handling precautions Outlet height Category 5 and Category 6 cables must be installed with care to ensure maximum performance. Stretching, sharp bending, kinking, crushing or jointing of the cable must be avoided to ensure that the pair twist and conductor spacing are maintained. When installing the cables: Keep at least 50 mm (preferably more) away from power cables and appliances whether or not there is an interposing barrier. Where it is necessary to cross power cables, cross at right angles. Avoid excessive tension when pulling cables in and don t allow any kinks or knots to form in the cable. Ensure that any bend in the cable has a bend radius greater than 8 times the cable diameter. Ensure that the cable is evenly supported, protected from crushing or trampling during and after installation, and that the cable sheath is not appreciably distorted by mechanical protrusions, cable ties, clips or other securing devices. Do not staple the cable. If the cable needs to be supported or restrained within a building cavity (e.g. to keep it out of harm s way or to maintain separation from other services), use loose fitting devices such as conduit or conduit saddles. For surface runs on walls, use plastic trunking or conduit to house the cable. Make each run of cable as short and direct as possible while ensuring that the above requirements are met. Allow for 200 mm to 500 mm of slack cable to be left at each end after termination of the cable. Don t joint/splice the cables. If any cable is damaged or too short, replace the full length of cable rather than repairing with a joint/splice. Don t tee or tap off any cable. Only connect one TO socket to each cable. TOs should be mounted at the same height as the power outlets, which should not be less than 300 mm from the floor. Any TO provided to connect a wallphone should be mounted about 1300 mm from the floor. Document No Copyright Page 40 of 92

41 Socket orientation and shutters The sockets should be mounted on their wall plates with the contacts at the top to minimise the exposure of contact surfaces to dust and other airborne particles. All TO sockets that are within the reach of small children should be fitted with a shutter to discourage them from probing the socket with their fingers. Note: The socket contacts can be touched by a child s finger. It is possible to get a small electric shock from these contacts under certain conditions Socket connections The cable should be terminated on each socket to Gigabit Ethernet (1000Base-T) standard in accordance with Appendix C of AS/ACIF S009:2006 (refer to Figure 27 and Table 2 below). Only sufficient cable sheath should be removed to terminate the conductors on the socket. The conductor pairs should remain twisted right up to the termination, but in any case a pair should not be untwisted for more than 13 mm. Pair 3 (See Table 2) Pair 2 Pair 1 W G W B W O W (Contact numbering from the front of the socket) Pair 4 Bn Insulation displacement connectors Maintain pair twist up to the terminations Don't kink the cable maintain an inner bend radius of at least 8 times the cable diameter If a socket indicates conductor colour codes for "A" and "B", follow the colour code for "A" (see Note).

42 Broadcast outlets Description A broadcast outlet (BO) is a wall plate containing at least one coaxial TV socket for connection of TV equipment (e.g. a digital TV set, digital set top box or Foxtel Digital set top unit). F type coaxial connectors ( F connectors ) should be used for all digital TV connections. The F connector uses a threaded connection on both the front and the rear of the socket, as shown in Figure 28. Single-socket BOs will provide access to digital FTA TV or pay TV. Pay TV usually also provides access to FTA TV channels via the set top unit (STU) but these channels may not be the same as the local FTA TV channels. Therefore, dual-socket BOs are recommended to provide separate access to pay TV and local FTA TV. (a) F type coaxial cable connectors (b) A typical dual-socket BO Note: Crimped or compression type F connectors must be used for cable connections on each side of the BO. Figure 28 Broadcast outlet (BO) Number of outlets Cable type Cable length Up to four BO sockets (e.g. two dual-socket outlets) may be connected to the Telstra ONT via a passive 4-way RF splitter. Where more than four BO sockets are required, an RF amplifier must be installed. Refer to for more information. RG6 tri-shield or quad-shield coaxial cable should be used for the BO cabling (quadshield is recommended due to its superior shielding performance). RG11 quad-shield cable may be used between the splitter and the BO to extend the cabling limits without the need for an RF amplifier (refer to Table 5). The cable and other coaxial cabling components should meet the minimum performance requirements specified in Table 4 (see ). The total length of any cable connected between the ONT and any BO should not exceed 23 m unless: less than four BO sockets are installed; RG11 cable is used instead of RG6 between the splitter and the BO; or an RF amplifier is installed.

43 Refer to and Table 5 for details. The cable length limit includes the cable from the ONT to a splitter, the cable from the splitter to the BO and any HD patch cord. Note: Cabling method Where less than four BO sockets will be installed, it is strongly recommended that the total cable length be limited to 23 m (or up to 32 m if using RG11 cable between splitter and BO) to allow for the future addition of a BO socket without the need to install an RF amplifier. The BO sockets should be cabled individually from a splitter located at the HD to support future cabling system upgrades, as shown in Figure 29 (a). Figure 29 (b) shows an alternative cabling arrangement for dual-socket BOs that is acceptable for changing single-socket BOs to dual-socket BOs but which is not recommended for new installations. Only RG6 coaxial cable may be run from the Telstra ONT to the HD. RG6 or RG11 coaxial cable may be run from the HD to the BOs. General guidance on the installation of coaxial cables and connectors will be provided by Telstra Document No A09, Information for Cablers and Customers Broadband cabling guidelines.

Stretching, sharp bending, kinking, crushing or jointing of the cable must be avoided. Coaxial cables should not be bent to a radius less than 10 times the cable diameter. All coaxial cable connections must be made using crimped or compression type F connectors. Cables should be prepared with the correct coaxial cable stripping tool and connected with a good quality crimping/compression tool. For more information, refer to Telstra Document No A09, Information for Cablers and Customers Broadband cabling guidelines. BOs should be mounted at the same height as the power outlets and TOs, which should not be less than 300 mm from the floor. Document No Copyright Page 44 of 92

45 In-home channels A locally generated RF signal (e.g. a UHF channel from a CCTV camera or a home entertainment system) may be injected into the TV cabling, as long as the locally generated signal is transmitted above 760 MHz (i.e. channels 62 69). The local signal may be injected into the cabling system using a combiner, diplexer or directional coupler in conjunction with a 760 MHz high pass filter as shown in Figure 31. Alternatively, a suitable diplex filter may be used that incorporates a 760 MHz high pass filter on the local signal input port. The high pass filter must have a stop band rejection greater than 20 db. The local signal can be picked up by any TV set in the home by simply tuning in to the relevant channel. The additional loss introduced by combining a local signal with the ONT signals will necessitate the use of an RF amplifier, as indicated in Figure 31. RF splitter/ amplifier To RF splitters or BOs Power MHz From ONT Combiner MHz From internal RF source UHF channels MHz high pass filter Figure 31 Injection of locally generated TV channels (e.g. CCTV or home entertainment system) Patching of BOs at the HD End-user patching of BOs at the HD is not recommended for safety and technical reasons. Note: Coaxial cabling specifications The outer conductor of coaxial cable is a live conductor and an electrical shock hazard may be present on the metallic body of any coaxial connector under certain conditions. Also, poor coaxial connections can degrade system performance and allow the egress of RF signals creating electromagnetic interference (EMI). Technical information specific to Telstra Velocity is provided in Table 3. Detailed guidance on installing coaxial cabling connected to a Telstra network is provided in Telstra Document No A09, Information for Cablers and Customers Broadband cabling guidelines. The general performance requirements for coaxial cabling components are set out in Table 4. Document No Copyright Page 45 of 92

This may avoid the need to install an RF amplifier if BO sockets are to be added at a later time. However, where this is not possible, the table indicates the cabling distances that may be achieved if fewer BO sockets are provided Power outlets for TOs and BOs It is recommended that 240 V power outlets be provided near all TOs and BOs for powering of customer equipment (see Figure 25).

57 (a) HD with PSU, patch panel and Ethernet router/switch (b) Use shallow mounting blocks to facilitate easy removal of plates Notes: 1. In the above example, the patch panel is installed in a cupboard and uses the internal wall cavity to house the cables and mount the wall plates containing the patch panel sockets. 2. A minimum space of 450W x 600H x 200D (in mm) is required for the above patch panel but a space of 600W x 650H x 250D is recommended. If the ONT is mounted internally (e.g. multiple dwelling units), it should be mounted below the patch panel, in which case a minimum height of 1030 mm is required (see 7.3.3). 3. The patch panel and the power outlets are mounted on different sides of a wall stud so that the power and telecommunications cables are in different wall voids to maintain the required separation between them. 4. At least one double power outlet should be provided and enough wall or shelf space for a surge protective power board, Ethernet router/switch, etc. 5. While the wall plates can be recessed into plasterboard, the wall plate cut-outs will weaken it if it is not reinforced. 3-ply should be used at the front or rear of the plasterboard to strengthen it. Alternatively, particle board or medium density fibre board may be used instead of plasterboard for mounting the plates. 6. The use of shallow mounting blocks is recommended, as shown in (b) above, to facilitate easy removal of the wall plates for future testing, repairs or alterations. This is particularly important if the mounting surface is painted, as the plates will tend to stick to the paint making them difficult to remove safely. 7. The 4-pair category 5 or category 6 cable from each TO socket is terminated directly onto the corresponding patch panel socket as shown in Figure 38. Intermediate termination modules should not be used. 8. Colour coding of the sockets at the TOs and the HD avoids the need to mark them Phone and Data (or similar), which is misleading because each socket can be used for any purpose. However, each TO wall plate should be numbered with corresponding numbering on the relevant sockets on the patch panel. 9. Two patch cords should be provided for each dual-socket TO connected to the HD plus two additional cords. Cords should be Category 5 or Category 6 (as applicable to match the cable rating), straight through (not crossover ) type, 0.5 m long.

58 Note: The cables from the TOs should terminate directly onto the patch panel sockets. Intermediate termination modules are unnecessary and may degrade performance. Figure 38 Termination of cables on the rear of the patch panel shown in Figure Basic home cabling system This home cabling system provides limited capacity for wired Ethernet connection of the broadband Internet service to personal computers (PCs) and generally relies on the use of cordless telephone handsets for distribution of telephone services. PC networking may be supplemented using wireless or powerline technology. Only one BO is provided for access to Foxtel Digital and digital FTA TV, which may be supplemented by antenna access to FTA TV. A conceptual diagram of this cabling system is shown in Figure 39. An example of a suitable cabling arrangement with typical connections is shown in Figure 41. This cabling system requires a basic HD for connection of services. The HD comprises a total of twelve 8P8C sockets that may be housed on two wall plates, as shown in Figure 41. Sockets and wall plates may be added to support additional TOs or TO sockets if required.

Data Figure 41 Typical patch panel layout for a basic home cabling system using wall plates and sockets 6.4. Connection of other cabling sub-systems Security Many homes have an intruder alarm system that provides for back-to-base monitoring via the public switched telephone network. In such cases, it is important that the alarm panel has connection priority over all other connected equipment (except for any medical alert system, which must take top priority). This is achieved by the use of a line grabber or mode 3 connection arrangement. Most intruder alarm systems are cabled separately using special cable with stranded conductors. A standard system comprises an alarm panel, motion sensors, audible and visual alarms, and a control panel. The alarm panel is the cabling hub for the system and is usually secreted away in a cupboard or robe. Where a monitored ( back-to-base ) security alarm system requiring a mode 3 connection is to be installed, the first telephone line from the ONT should be connected to the security alarm panel before it is presented to the HD patch panel. This may be achieved by running a single Category 5 or Category 6 cable between the HD and the alarm panel with the first telephone line jointed through to the alarm panel within the HD. The line is fed back from the alarm panel using a second pair in the same cable and this pair is connected to the patch panel. Figure 42 shows this cabling arrangement. A monitored security alarm should always be connected to the first telephone line even if two or more telephone lines are to be activated. If a security alarm system is installed, it will have battery back-up so that it will still operate during power failure or if the power is switched off at the power mains. Therefore, the Telstra PSU should also be fitted with a back-up battery so that the telephone line will work under the same conditions. Document No Copyright Page 61 of 92

With a mode 3 connection, the alarm panel takes priority over the line and disconnects all other customer equipment when the alarm is activated. It is important that the alarm panel be the first connection point on the line to which it is to be connected. The alarm panel should always be connected to telephone line 1 (POTS 1) even if two or more telephone lines are activated. 2. The mode 3 socket may be installed on the wall next to the alarm panel, inside the alarm panel or inside the home distributor (or the alarm panel may even be hard wired). The connection principle is the same in all cases. 3. The Telstra PSU should be fitted with a back-up battery if a monitored security alarm is installed. TV ONT Figure 42 Connection of a monitored ( back-to-base ) security alarm system Home automation Home automation, such as intelligent lighting and push-button or remote control of electrical appliances, is usually installed as part of the electrical wiring system by the electrician. The control cables for such systems may be bus-wired or star-wired from a central control unit, which may be located near the HD. While the home automation wiring is usually a separate cabling system to the telephone, data and TV cabling described in this document, the home automation control unit may be connected to the HD to provide remote control of appliances via Document No Copyright Page 62 of 92

63 Home theatre the telephone network or the Internet. This can be facilitated via a socket in the patch panel or via a mode 3 connection arrangement as described in Home theatre cabling is generally installed as a separate cabling system by audio/video cabling specialists. There may be some common elements in the TV (coaxial) cabling system but the audio wiring (e.g. for loudspeakers) is generally point-to-point, heavy gauge, stranded conductor cable and should be totally separate. A TO (connected to the HD) should be located near each BO (TV outlet), whether or not the BO forms part of a home theatre system, to provide for such things as: analogue audio distribution to amplifiers or low-power speakers in each room (e.g. for music distribution) digital (Ethernet) connection of network media players (e.g. for music or video distribution or streaming ) digital video on demand (via the Internet) IPTV (via the Internet) remote control of appliances in other rooms (e.g. infra-red remote control repeater) Connection of customer cabling at the Telstra ONT General Sufficient slack should be left in each cable in the roof space to support drawing down additional cable length to the ONT for future cabling alterations or replacement of the ONT. Generally, this slack cable should be no less than 200 mm and no more than 1 metre. The customer cabling is connected to the Telstra ONT by three or four cables: a 4-pair Category 5 or Category 6 cable for the four telephone lines a 4-pair Category 5 or Category 6 cable for the broadband Internet ( Data ) service an RG6 coaxial cable for the digital FTA TV and pay TV connection an additional 4-pair Category 5 or Category 6 cable for a possible, future, second Data service (recommended). Use 4-pair cables with different sheath colours, e.g. blue for data and grey for telephone. Alternatively, mark the cable sheaths at each end, e.g. Data and Phone. Telstra does not support the connection of any additional cables at the ONT. Additional cables should be connected via an HD or some other internal distribution device or method. Cablers may gain access to the ONT connections via the cover securing screw designated CUSTOMER ACCESS, using a standard flat-blade or No.2 Phillips-head screwdriver. The customer cable connections at the ONT are shown in Figure 43. Document No Copyright Page 63 of 92

The grommets are made of foam rubber and are provided in two sections one in the base and one in the lid. It is important to cut the grommet in the base where the cables enter to ensure that the grommets seal the cable entry properly. It is equally important not to cut the grommet in the lid. Using diagonal cutters, cut the cable entry grommet at each cable location (see Figure 44) and lay the cables in the cuts. Tie the cables to the cable tie supports as shown in Figure 43. Do not overtighten the cable ties. Document No Copyright Page 64 of 92

65 Foam rubber grommet Grommet cut locations Notes: 1. Only cut the grommet where a cable or cables will lay. Up to four cuts may be made depending on the number of cables entering the cable port. 3. Use side cutters to cut the grommet. Figure 44 Cutting the cable entry grommet Telephone cable CAUTION: Use a large flat-blade screwdriver (7 mm blade) on the ONT screw terminals (see Figure 45). Using a smaller screwdriver carries a high risk of personal injury or damage to the ONT status LEDs, as a smaller screwdriver will tend slip off the screw while exerting enough pressure on it to turn it. Connect the 4-pair cable provided for the telephone services to the telephone line terminals in accordance with Figure 45. Connect pairs 1 to 4 to the terminals for lines 1 to 4 respectively (line 1 is at the top and line 4 at the bottom). Refer to and Table 2 for the cable colour code for various cable types. The coloured mate connects to the red terminal (R) and the white mate connects to the green terminal (T). Document No Copyright Page 65 of 92

Use a large (7 mm blade) screwdriver on these terminals to minimise the risk of the screwdriver sliding out of the slot and causing personal injury or damaging the ONT status LEDs. 2. Each line has a green and red screw terminal, designated T ( Tip ) and R ( Ring ). T is the L+ or A leg while R is the L- or B leg. Connect the white mate of each pair to the green terminal and the colour to the red terminal as shown in (a). Refer to and Table 2 for the cable colour code for various cable types. 3. Strip the cable sheath at the top of the terminals as shown in (b). Cut all conductors to a length of about 150 mm, strip the conductor insulation about 30 mm beyond the terminal it is to be connected to, then wrap the bare conductor clockwise around the screw between any two washers as shown in (c). Tighten the screw and break off or snip off the excess conductor. Leave a gooseneck in the slack conductor as shown in (b). 4. No more than one conductor should be terminated on any screw terminal post. Additional cables should be connected via an HD or some other form of internal distribution device. 5. The test sockets are 6P modular ( RJ11 ) sockets. These may be used by a cabler or a customer to test the lines at the ONT using a standard telephone that has a line cord with a 6P modular ( RJ11 ) plug. However, customer testing should be performed at the HD patch panel first and the ONT should only be accessed by the customer if there is no dial tone at the patch panel.

67 Broadband Internet cable The cable for the broadband Internet service must be connected via an 8P8C plug to the Ethernet socket in the ONT (see Figure 46). The plug must be connected to the Category 5/Category 6 cable on site using a modular plug crimping tool in accordance with Figures 47 to 51. The 8P8C plug used must be a type designed to crimp to cables with solid (not stranded) conductors. Broadband Internet ("data") socket Second "data" socket (not currently used) Ferrite core (Note 1) Cable tie (Note 2) (a) Ferrite core supplied with the ONT (b) Fitting of the ferrite core Notes: 1. A ferrite core is stored in the ONT for fitting by the installer of the customer cabling. Clip the ferrite core around the broadband Internet cable as close as possible to the socket (in earlier versions of the ONT, the ferrite core was clipped around the coaxial TV cable). 2. Tie the cable lightly to the cable tie support, as shown above, to prevent the ferrite core slipping down to the bottom of the ONT.

69 Notes: 1. Untwist, fan out and line up the conductors ready for insertion into the plug, in accordance with the colour code shown in Figure 27 and Table 2 in Insert the conductors into the plug, ensuring that they feed correctly into the correct slots. 3. Push the conductors firmly into the plug and ensure that they extend all the way to the end of the plug. Figure 49 Connection of 8P modular plug preparation and insertion of the conductors Notes: 1. Double-check the colour coding of the plug conductors and that the conductors are properly located in the plug. 2. Seat the plug in the 8P receptacle of the crimping tool, support the cable at right angles to the tool, and crimp the plug.

70 Note: Visually inspect the plug to ensure the contacts are recessed in the plug, the cable sheath is properly restrained, and that the conductors appear to be properly seated within the plug. Figure 51 Connection of 8P modular plug visual inspection TV cable Connect the coaxial cable to the TV port (female F connector) on the ONT using an external-rated male F connector, as shown in Figure 52. It is not possible to leave any slack coaxial cable in the ONT. However, leave sufficient free play in the cable to allow the F connector to be connected and disconnected without exerting any strain on the cable. CAUTION: Once TV appliances are connected to the coaxial cabling, an electrical hazard may be present on the coaxial cabling due to leakage currents or a faulty appliance. Follow the proper electrical safety precautions before disconnecting the F connector from the RF port of the ONT. Document No Copyright Page 70 of 92

71 External rated F connector Cable guide flange Coaxial cable Notes: 1. Run the cable to the right of the cable guide flange to ensure that the required minimum cable bend radius is maintained and that there is sufficient free play in the cable to disconnect and reconnect the F connector. 3. Use an external-rated female F connector. Tighten the F connector on the threaded TV output port using a torque wrench set to inch lbs PSU cable Earthing conductor 6.6. Testing Figure 52 Coaxial cable connection in the ONT The PSU cable enters the right-hand cable entry port and passes under the broadband internet cable on the right side of the ONT into the top of the Telstra ( Telco ) compartment. This is a black cable and can be seen in Figure 43. Telstra will connect this cable at the same time as the optical fibre lead-in cable is connected. The earthing conductor can enter either the right-hand or left-hand cable port, whichever is more convenient. This cable is connected at the bottom of the Telstra ( Telco ) compartment. Telstra will connect the earthing conductor on the ONT at the same time as the optical fibre lead-in cable is connected Category 5/Category 6 cabling As long as cables have been installed properly (in accordance with ) and terminated correctly (in accordance with ), in homes where cable runs are relatively short it should only be necessary to perform a wire map test on the TO cabling to verify correct cable connections.
