NBN Co begins DOCSIS 3.1 switch-on

8 Aug 2018

Technology vendor ARRIS has announced that it is working with NBN Co, the company overseeing the construction of Australia’s National Broadband Network (NBN), to bring DOCSIS 3.1 cable broadband access technology to three million premises in ‘major’ cities by 2020. Following a relaunch of activations on NBN’s HFC network in April 2018, the company has claimed there was ‘no better time’ for it to begin switching on DOCSIS 3.1, and said it was doing so with a view to supporting a ramp-up of activations on its cable infrastructure.

While it is believed that the initial phase of the DOCSIS 3.1 rollout covers several thousand premises in Sydney and Melbourne, NBN Co has not published an official list detailing where the technology has been made available, nor has it released a rollout schedule. Meanwhile, NBN Co says that most premises in HFC areas will not have to do anything to access the technology, confirming that the majority of the Network Termination Devices (NTD) that are already operating inside premises are already DOCSIS 3.1 capable, and will be able to take advantage of the higher-performance tech as soon as it is activated in an area. However, it noted that there are still a small number of premises covered by its HFC network with DOCSIS 3.0 NTDs, earmarked for replacement with DOCSIS 3.1 models ‘in the coming months’.

Ray Owen, NBN Co CTO, commented: ‘DOCSIS 3.1 will not only double the capacity of the NBN Co HFC network, but it will also help us deliver a more stable and resilient service for end-users with the advanced technologies that it uses.’
