NBN ConstructionKey Features• Fibre To The Premise—FTTP: (100Mbps) to 90% of premises • Satellite and wireless (12 Mbps) to the remaining 10%• Roll-out over approximately 8 years• 10 million + points of connection• Some 4000 points of connection per day• Direct construction workforce of between 15k to 20k FTEs at the peak of construction

NBN Scale Comparison

Design objectivesCoverage• Consistent network capacity and performance• Consistent design rules with limited flexibility in line with geographic characteristics

Competition• Transparency consistent with equivalence• Wholesale only, open access design• Standardised interfaces

Cost effective• Total cost of ownership perspective• Competitive tender process• Planning for the future incl. clear upgrade path• Adherence to standards

Customer care• Focus on reliability• Modularity to allow flexibility

NBN Reference ArchitectureEnd User

• Device: Set-top box, Phones, Pc’s• RG router gateway: IP,NAT, Firewall, DNS• Terminal

• ONT/NTU : Ethernet – fibre (ATA)• WNT/SNT : RF modem

Access: Ethernet Aggregation Switchaggregates multiple OLTs at a local exchange site.

Aggregation & Transport: lots of connectionsonto a smaller number of EAS - local to national

Service Edge & Core: connectivity between devices and applications & content via NSP, RSP, ISP

Applications & content: services like health,web-based apps, IP phone, Smart meter, TV

A Diversity of Wholesale and Retail Business Models

Physical Infrastructure Representation

Network Terminal Unit• NTU or ONT (optical) / WNT (wireless) / SNT (Satellite)• Terminal configuration depends on service• Ethernet ports (UNI-D), RJ-45 ports(UNI-V)• Each UNI-D is a fully independent interface, • Interfaces supported for UNI-D ports:

• 10/100/1000BaseT/TX (Electrical) • 1000BaseTX (Electrical) • 1000BaseSX (Optical) • 1000BaseLX (Optical)

Fibre Structure• Plug and Play – Fibre Distribution Hubs (FDH) are

manufactured with pre-terminated fibre cable stubs, and enable connectorised splitter modules to be easily installed as required according to customer requirements

• Connect up to 2 fibres per dwelling• larger multiports can be plugged in for additional capacity

Retail Service Providers

NBN benefits

• Service is IPv4 and IPv6 compliant, uses DHCP for dynamic assigned address by retail provider • Multicast compliant – use for broadcast TV and so on• ONT Management and Control Interface (OMCI): IP address (and other ATA parameters) are assigned via

the WTAS Provider’s management system. The RSP needs to interact with the WTAS Provider’s management.

• Tasmania hooked up – customers are already claiming speeds that exceed expectations.

• Mr Hayward said that harnessing technology to change business models was one of the ways industry could reduce its carbon footprint. He said that downloading music over the internet probably had one seventh the environmental impact of a consumer driving to the shops to buy a physical CD which had been manufactured, packaged and transported to a retail outlet.

• Citing statistics from Access Economics the white paper suggests that investing $35-$80 billion in innovative technologies over the next decade could generate 70,000 new jobs. It also noted IDC’s analysis that Australia could cut its CO2 emissions by 116 megatonnes over the decade by using smarter technologies in energy, buildings, transport and industry.

• There are probably more than 350 reasonably sized data centres in Australia. The vast majority have exceeded their use by date and are taking up expensive real estate. The NBN could provide a means to consolidate to a couple of dozen data centres which could draw their energy from co-generational gas fired power stations.

Glossary• Ethernet Aggregation Switch (EAS)

The equipment that provides aggregation of FSAs to an AN for each retail service provider (RSP) and wholesale service provider (WSP).• Ethernet Fanout Switch (EFS)

The equipment that provides port fanout/expansion between the Point of Interconnect (POI) and the Optical Line Terminal (OLT) for each retail service provider (RSP) and wholesale service provider (WSP).

• Fibre Access Node (FAN)A facility that houses the active equipment providing services to a Fibre Serving Area (FSA).

• Fibre Distribution Area (FDA)The area served via a single Fibre Distribution Hub (FDH) which connects addresses to the serving FAN site(s) via Local Fibre.

• Fibre Distribution Hub (FDH)A facility that houses the optical splitters.

• Fibre Serving Area (FSA)The area served by a Fibre Access Node (FAN) site, which will be a cluster of Fibre Distribution Area (FDA). The FDAs will be connected via Distribution Fibre.

• Fibre to the Premises (FTTP) FTTP uses an extensive network of optical fibre cables reaching all the way to the premises, with Gigabit Passive Optical Network (GPON) fibre-sharing. It has the capacity to handle several phones and PCs and a high-definition TV or two simultaneously.

• Gigabit Passive Optical Networking (GPON)An optical-access system based on Internet Protocol (IP) that lets multiple homes or businesses in a neighbourhood share fibre from a service provider's central office.

• IEEE 802.1, 802.3 –Ethernet Standards• Multi Dwelling Unit (MDU)

Typically refers to blocks of flats, apartments etc.• Optical Line Terminal (OLT)

The terminal equipment to provide the Gigabit Passive Optical Network (GPON) signals to each of the Fibre Distribution Areas (FDAs).• Optical Network Terminal (ONT)

Refer to the NBN Co. termination point on each premises, for residential service providing (typically) 4 Ethernet, 1 telephone and 1 co-axial ports.• Plain Old Telephone Service (POTS)

POTS refers to the standard telephone service. In contrast, telephone services based on high-speed, digital communication lines are not POTS. The main distinctions between POTS and non-POTS services are speed and bandwidth. POTS is generally restricted to about 52 Kbps.

• Passive Optical Network (PON)• Point of Internconnect (POI)

PON is a point-to-multipoint, fibre to the premises network architecture in which unpowered optical splitters utilizing Brewster's angle principles are used to enable a single optical fibre to serve multiple premises, typically 32-128.

• Retail Service Providers (RSPs)The retail network service providers and application/content service providers are those that provide services to end users and have a direct customer relationship with the end users. Wholesale service providers do not have this relationship.
