The connection point is the boundary between the provider's network and the network inside the building. It is often located in the basement, the meter cupboard or a technical room. It is also known as the demarcation point.
Up to the connection point, the provider is responsible. After that, the internal infrastructure begins: the cabling to the floors, the patch cabinets and the access points.
"Fibre available" often only means that the fibre runs to the connection point. For the IT-Label, what happens after that counts as well. A building with IT4, for example, has a connection into the building, but no internal IT infrastructure yet.
What does this mean for the IT-Label?
The connection point belongs to the Connectivity component. The audit looks at which connection comes in and how much capacity it has. But the label also looks beyond the connection point: under Infrastructure, what counts is how the signal reaches the floors via the structured cabling and the technical room. A building with only a good connection but no internal infrastructure therefore does not get beyond IT4.
