Wanting Your Existing Phone Sockets to Work With an NBN 

Does NBN know about the 52 volts?

There is a lot of confusion at the moment about getting your existing phone sockets working correctly with a new NBN HFC (hybrid fibre coaxial) connection. We are asked often can use multiple phone sockets with NBN. If your NBN connection is coming through your existing Foxtel cable, or NBN has installed a new coaxial lead-in cable and socket to your home if you want to connect your existing phone sockets and have them working like before there are a few things that need to happen.

Note: Your existing phone sockets can work with all the NBN connection methods, we are just highlighting HFC

We are not exactly sure why your NBN-installing contractors are not taking the time to do these few things to get your existing phone sockets working.

  1. NBN contractors are not licenced, trained or qualified to work on this solution.
  2. NBN doesn’t realise that this is a potential problem for tens of thousands of Australians.
  3. NBN do realise after the fact but hasn’t budgeted for it.
  4. NBN is looking out for us private technicians by providing more jobs

We have been informed by many of our clients that when your HFC connection is completed, the NBN installing technician in many cases tells you that you can only use one phone now and it has to be plugged directly into the NBN router. This is NOT correct. If done correctly you can use your existing copper line phone sockets throughout your home or business for a multiple-phone setup just like before.

Watch this video below it will show you exactly the reason that in most cases you can’t just plug from your router phone outlet directly into your existing home phone wall sockets.

The Problem 

As you can see from this video the NBN technician is not informing their customers that in order to use your existing phone sockets your Telstra lead-in cable will need to be removed. This cable if it is still connected back to the LI in the exchange will be sending 52 volts DC down the line. If this is plugged into your router it could not only damage your router but it will not allow your phone sockets to work properly or at all.

Really Telstra or NBN should send someone to the exchange when you get an NBN line and physically disconnect your main pair from the LI that generates the 52 volts. This would be a gradual decommissioning of the Telstra main pair copper network, and it would stop voltage flow that is not useful anymore.

Even if they did disconnect from the exchange you will still need to locally disconnect from the Telstra copper network inside your home because then your dial tone coming from your router is now going out into the copper network, and who knows what kind of mischief that could lend itself to.

The Solution 

We are licensed trained and certified to perform this service, we are private NBN technician . If you are wanting to use your existing sockets I hope I have demonstrated effectively that this is an issue that is going unnoticed and will needed to be taken care of correctly if you are to use your existing phone sockets safely and securely or at all.
