How do I know if I have nbn Fibre to the Node (FTTN) or Fibre to the Building (FTTB)?

Fibre to the Node (FTTN) and Fibre to the Building (FTTB) usually look very similar inside the home.

The main thing to check is whether your modem or router plugs into a telephone wall socket.

What to look for:

  • A regular phone socket on the wall
  • Your modem or router plugged straight into that socket
  • No separate nbn connection box between the wall and your modem

In simple terms:

  • If your internet comes from a phone wall socket
  • And your modem or router plugs into that socket directly
  • You may have FTTN or FTTB

As a general guide, FTTN is more common in houses, while FTTB is more common in apartments or units.

For BYO setup, both FTTN and FTTB normally need a VDSL-compatible modem/router.

💡 Tip: If you still have an old ADSL filter plugged into the wall, remove it. These can stop your FTTN or FTTB service from working properly.
