Giganet full fibre broadband connections all connect into an Openreach ONT. The ONT is a white box that connects to a full fibre optic cable, which runs directly to your property from the local exchange and provides broadband and phone (if Giganet Home Phone is provided).
There are several lights on the ONT, when these lights change colour or flash, it means something is happening.
There are five different types of Openreach ONT; they all work in the same way, but the type and number of lights may vary between devices.
