What to look for:
- A telephone wall socket
- An nbn connection box plugged into that socket
- Your router plugged into the nbn connection box

In simple terms:
- Phone wall socket
- Then nbn connection box
- Then your router
If your router plugs straight into the phone socket, it’s more likely FTTN or FTTB. If there is a separate nbn box between the wall socket and your router, it’s more likely FTTC.
