Underneath the box, from left to right, are 3 connectors – power, optical fibre in, LAN out. That last one is what goes to your router.” I guess its because some households already have an ONT modem thats functional so no need for openreach.

You must always plug your Smart Hub into the Openreach modem port PORT 1. If you're connected to PORT 1 but have no internet connection, try plugging the Ethernet cable (red ends) into the next one along. After a few minutes a blue light will show your hub is ready. Congratulations! If you’re reading this then I’m guessing you’ve upgraded to Full Fibre, or FTTP (Fibre to the Premises) as it’s also known. With vastly superior speeds over traditional fibre broadband, it’s slowly rolling out across the UK. As you can see there are 4 lights at the top of the OpenReach Full Fibre modem – Power, LOS (Loss of Service or Loss of Signal), PON (Passive Optical Network) and LAN (Local Area Network – but you know this one, right?). Think of LOS as showing a cut in the fibre connection, whereas PON is indicating your connection at the other end of the network. Unless said ‘Landline Engineer’ as you call them is also FTTP Skilled then chances of him having one are none existent to not a chance. They’ve gone through a number of different models but, right now, are installing a compact little box made by Nokia. This is what it should look like…Underneath the box, from left to right, are 3 connectors – power, LAN out, optical fibre in, That middle one is the one that goes to your router. The ONT is negotiating a connection on the network. You’ll find this might happen a few times after initial installation. I’d recommend getting BT to send an Openreach Engineer out to replace it as they can get the correct ones direct from their Supply Chain. One aspect of the installation is a wall mounted modem (known as an ONT – Optical Network Terminal), which goes between the fibre connection outside and your router. No matter which ISP you’re with, OpenReach will have installed this for you and it will be one of their branded boxes.
