Ericsson Telecommunications Ltd, the former Thorn-Ericsson Ltd joint venture now wholly owned by the Swede, has been awarded a UKP5m contract to supply British Telecommunications Plc with what is thought to be the world’s largest distributed digital telephone exchange. Sited in London’s fast-rising Docklands community, the exchange consists of a series of pre-tested remote subscriber stages that are linked to each other by high-speed fibre optic cable, and then linked on into the main AXE exchange which is installed at Hackney. The units are all pre-tested at the Scunthorpe facility, and can be installed and running within just two days, claims Ericsson.
