Australia - National Broadband Network - FttN and VDSL
In April 2014 the government formally opted for the NBN to provide a multi-technology mix rather than be predominantly FttH. Under the new scheme, FttH will connect 26% of premises by 2020, while a further 44% will be served by FttN - using the VDSL technology - and the remaining 30% of will receive services via existing HFC networks. Using this approach, the government anticipated that 91% of premises connected to fixed-line infrastructure would receive 50Mb/s by 2020. The capital cost was put at $29.5 billion (US$27.4 billion).
The NBN Company (their official name changed to NBN in 2015 but for practical reasons we will refer to them as NBN CO) was also instructed to focus on serviceable premises as a performance metric, as opposed to the number of premises passed, by which a large number of premises had been passed by fibre but could not in practice receive services. NBN Co was serve 6,000 brownfield premises per week by mid-2014.
In December 2014 Telstra and Optus signed agreements with NBC Co setting out the terms under which their copper networks will be incorporated within the NBN. When regions are declared ready for service, Telstra is obliged to cease advertising new retail and wholesale services, and will have an 18 month period in which its customers will be migrated to the NBN. For Optus, its HFC infrastructure will be retained in areas where it provides the best means to secure broadband for premises in the region.
The number of premises with an active NBN service across all access technologies has increased from 70,100 in June 2013, to 130,700 the end of 2013, 156,000 in June 2014 870,000 by April 2015. NBN Co planned to connect over 3.1 million premises by September 2016.
