BT's network development to support the Data Wave is well advanced. By the end of this year, we will have over 600 SDH (Synchronous Digital Hierarchy, a transmission system for high bandwidth) nodes and 100 ATM switches across the UK. Over the next 5 years, we expect to increase the capacity of this network by about 10 to 12 fold. We also expect to extend the coverage of our SDH network to around1500 to 2500 nodes. This network is planned to have ATM switches at around 200 to 400 nodes (depending upon demand), and ATM access points at around 1200 to 2000 nodes. Obviously, the size and extent of network rollout will depend on the volume and distribution of demand. In the core of this broadband network, we are planning to install a set of large trunk switches that perform both narrowband and broadband switching, including interconnection between the PSTN and ATM networks. A similar rate of growth is expected for our national IP network, which is largely transported over this ATM network.
