In Germany in specific building there is only one provider available in your telephone socket, and one in your cable socket in your apartment. Frequently there is no cable socket.

That's not relevant. Over a Deutsche Telekom phone line you can choose an ISP. The ISP sometimes has a layer two connection to you and therefore has their own infrastructure or they have a layer 3 connection in which case you suffer from the Telekom policies.

Layer 2 = their infrastructure connects you to the internet

Layer 3 = theyre literally just a reseller, DTAG is providing your internet connection, the ISP just billing etc.

		That's too many words for simply saying "The fastest available DSL is 16Mbit/s and the customer service will be rude and useless".
