Your home phone connects differently depending on the type of nbn technology you have.
This article explains the different technologies and whether your phone plugs into an existing socket, a modem, or a connection box.
1. Fibre to the Building (FTTB) and Fibre to the Node (FTTN)
2. Fibre to the Premises (FTTP)
If you have a FTTP nbn service, your phone can work in two ways:
- You can plug your phone into your modem if you have internet as part of your nbn service with Telstra.
- If you don’t have the internet with Telstra as part of your nbn service, then your phone will plug directly into the nbn connection box.
Good to know:
- FTTP nbn services can have an optional battery back-up so you can use your home phone during a power failure. Installation charges may apply. However, in some circumstances, Telstra requires you to have a battery back-up unit as part of your home phone service on the nbn network.
3. Hybrid Fibre Coaxial (HFC)
If you have HFC nbn service, you plug your home phone directly into the green port on your Telstra modem. Your modem plugs into the nbn Connection Box that the nbn co technician installs.
4. Fixed Wireless
If you have a Fixed Wireless nbn connection, you can choose to keep your existing copper phone line. This means you can use your phone during a power failure, depending on your handset.
If you don’t need a copper phone line, you can switch your phone to the nbn network.
If you do switch to the nbn network, you’ll need a connection box inside your home. You plug your modem into the connection box, and your phone into the modem.
How do I know which type of nbn connection I’ll get?
You can check your address on our nbn network rollout map*
*If nbn co is still planning the rollout in your area, that information may not be available yet.
Where should I put the nbn connection box?
You should put the connection box where you use the phone most, if possible. The nbn co technician may also advise you about good locations in your home when they visit your address.
Can I have additional phone sockets on the nbn network?
Additional phone sockets will not work, unless they can be re-wired for the nbn network.
If you need multiple sockets we recommend you use cordless handsets.
Good to know:
- You can’t install the nbn connection box in a wet area like a bathroom or laundry.
- The nbn connection box has lights. So you may not want it in a bedroom.
Will my phone work in a power failure?
No, in most cases your home phone won’t work in a power failure, because the nbn network needs power.
But it WILL work if you have:
- A Fixed Wireless connection and have chosen to retain your existing copper phone line, or
- Fibre to the Premises with a battery back-up unit, which maintains power to the nbn network.
