Information Technology Plc, ITL, has received UKP500,000 worth of orders from Austin Rover, Ford, Land Rover and Jaguar for its Cablestream broadband cable systems in recent months: the networks, which cost between UKP10,000 and UKP60,000, allow a wide variety of different computers, terminals and other equipment to be linked over a single cable which runs through a large factory site; sales for Cablestream have now reached UKP5m since it was introduced five years ago.
