Where to plug in your telephone handset with NBN?


Did you know that the NBN allows both your internet (data) and your telephone (voice) to work over the internet connection? This means with NBN we no longer need to plug in our telephone handset into the old copper-based telephone wall sockets. Instead, we need to plug the telephone handset into either the Modem or into the NBN Connection Box, depending on what type of NBN technology you have at your premises.


Fibre To The Premises (FTTP)


If you have an NBN Connection Box and/or a Back Up Battery like in the below diagram, you have Fibre To The Premises. You need to connect your telephone handset into the Uni-V port on the NBN Connection Box.





NBN Fibre To The Node (FTTN), NBN Fibre To The Building (FTTB), NBN HFC (Hybrid Fibre/Coaxial), Fibre To The Curb (FTTC) or Fixed Wireless


For all other NBN technologies, you need to connect your telephone handset into the Phone 1 or Phone 2 port on the back of your modem.




Tip! When the phone is plugged in, the Phone 1 or Phone 2 light on the front of the modem will be lit. When the telephone is in use, the light will be flashing.

Unfortunatly my connection is through the old foxtell cable which is nowhere my old phone landline connection.  How am I supposed to hook up my phone?

Its allright to draw a cable on a plan but my phone connection is two rooms away from the NBN box.  The installers didn't warn me about this!!
