  1. National Broadband Network – NBN Co By Nicole Rowland

  2. 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

  3. NBN Scale Comparison

  4. Design objectives Coverage • 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

  5. Diversity in Wholesale Model

  6. Optical Fibre • Optical fibre is a thin glass or plastic strand that carries light along its length • Light is shone from lasers down the fibre and detected by a receiver at the other end • Light within the fibre does not escape because of cable design • They don’t conduct electricity and thus you can never get a shock and they are immune to electrical interference. • It is capable of transmitting information at a practically unlimited rate over tens of kilometres. • Passive Optical Network is a “shared” fibre service used to connect households - the lasers located in a central location (FAN) and within the ONT at each home.

  7. Physical Infrastructure Representation

  8. NBN Reference Architecture End 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 Switch aggregates multiple OLTs at a local exchange site. Aggregation & Transport: lots of connections onto 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

  9. End UserNetwork 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)

  10. Access 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

  11. Network dimensions –replicating modules

  12. Other NBN information • Service is IPv4 and IPv6 compliant, uses DHCP for dynamic assigned address by retail provider • Multicast compliant – use for broadcast TV and so on • IP address (and other ATA parameters) are assigned via the Wholesale Provider’s management system. • NBN Co aims to have ownership of all current installed fibre, in the process of signing an agreement with Telstra and will tryto do similar deals with other companies like Optus etc. • Fibre will provide all phone and internet services to premises and copper wire will likely be removed. • Stephen Conroy still wants a filter, controversial. • Tasmania hooked up – customers are already claiming speeds that exceed expectations. • Households need to re-wire at own expense? • BBN (Brisbane) project implications
