Optical Network Terminal
If you’re getting your broadband through Fibre to the Premises (FTTP), you’ll need an Optical Network Terminal (ONT) in your home to set up your hub, instead of a normal master socket. It lets us run fibre cables all the way to your home – giving you a faster and more reliable speed.
You should already have an ONT in your home if we’ve told you we’ll activate your broadband without needing to send an engineer. But to make sure we can get your broadband up and running on your activation date, you need to check it's working before then.
Find your ONT and check it's working:
- The Power light should be green. If it’s not, check:
- The power cable is plugged firmly into your ONT.
- It's plugged in and switched on.
- It's not switched off on your ONT (if it’s got an ON/OFF switch).
- The PON light should be solid or flashing green.
- It’s attached securely to the wall and doesn’t look damaged.
Good to know: Like your hub, your ONT always needs power for your broadband to work so make sure you don’t turn it off.
Get in touch with us if, your LOS light is red or your ONT is damaged. Or if it’s after your broadband activation date and your PON light is flashing green.
Where is my ONT? What does it look like?
There are a couple of different types of ONT depending on when it was installed. But look out for a white box mounted on your wall near a power socket with an Openreach logo on it. It’s bigger than a normal telephone socket and might have:
- One or four Ethernet ports – These might be labelled PORT or LAN.
- An ON/Off button.
- A second white box connected to it (a battery backup unit).
You'll probably have one of these types of ONT's installed because they're the most common., but if you don't, look for something that look similar.
