Q&As: Docsis 3.1

Comments

When will Docsis 3.1 services be available?

We plan to run Docsis 3.1 trials in 2016 and we plan to have Docsis 3.1 services commercially available in 2017.

What services will be available once Docsis 3.1 is available?

Docsis 3.1 allows NBN Co the possibility to offer much higher speed services on the NBN – all the way up to 1Gbps – although when we launch these higher speeds will depend on demand from our Retail Service Provider customers.

What upload speeds will I be able to achieve on the new network?

Our initial HFC services will offer the same speeds that are available on the Fibre-to-the-Premises (FTTP) network – with a top speed of 100Mbps download and 40Mbps upload.

However, the arrival of Docsis 3.1 will allow us to increase both download and upload speeds quite significantly, in the US operators are talking about offering 1Gbps download and 100Mbps upload.

What is Docsis 3.1 and how will it provide better services?

Docsis 3.1 is the latest version of the Data Over Cable Service Interface Specification (DOCSIS) standard – superseding the current Docsis 3.0 technology.

Docsis 3.1 allows much faster speeds than are available on Docsis 3.0 by creating around 50% more capacity on the cable by transmitting data much more efficiently and using much more of the available spectrum.

Will the Pay TV (hybrid fibre coaxial) network be congested during peak periods, such as after work?

Even without the introduction of Docsis 3.1 NBN Co is building a much more robust HFC network with much greater capacity – we have already signed a deal to install over 230 state-of-the-art Cable Modem Termination Systems at the exchanges, these will provide much more powerful engines for the network.

So, bringing Docsis 3.1 on board is the cherry on the cake that will give us even more capacity and really make sure that there is plenty of bandwidth for everyone on the network to have a great experience.

Will I need to change my modem?

Yes – in order to access Docsis 3.1 services you will need a new modem and you will be supplied with this by your RSP.

I don’t currently have a Pay TV network (hybrid-fibre coaxial) connection, although the network is in my suburb.  Will I be able to get an NBN service?

If your home is in the HFC footprint area then you will be connected to the NBN – either via an extension of the HFC network or if you live in an MDU you may be connected by a Fibre-to-the-Building solution.
