The presentation describes a new scenario for how to transform the existing telephone access network into a real broadband network. The objective is to introduce a low-cost network evolution scenario, which makes maximal use of the huge investments connected to this kind of networks. The existing network is sub-divided into a small cell network, each covering an area with an approximate radius of 1 kilometer. Inverse multiplexing of xDSL systems is used to aggregate bandwidth in the range of 100 to 1000 Mb/s between nodes in the network. VDSL modems able to carry about 25 - 50 Mb/s, are used on the last section from the node to the customer premises. These modems provide all households within each geographical cell with real broadband access to a large common bandwidth.
