The backbone of the business.

In 1995/96, BT invested approximately £2.8 billion, primarily on modernising and expanding its network. In June 1995, a major milestone was reached when the last of BT's old analogue exchanges were replaced. Today over 7,000 digital and modern electronic local exchanges serve all of our customers.

*		Tomorrow, today. BT currently invests £9 per second on research and development into products and network services. These include optical fibre technology, ISDN (BT's Integrated Services Digital Network) and new interactive services - including video on demand, educational programming, home shopping and home banking - test marketed by customers in East Anglia this year.

Getting the picture. BT is one of the world's largest suppliers of videoconferencing systems, in a market estimated to be worth over £330 million and growing rapidly. The world market in visual services is expected to exceed £5 billion by 1997.*

BT's extensive portfolio of products and services is backed by ISDN and the world's first integrated multimedia conference bureau. ISDN enables high speed transmission of voice, image, data and text in any combination over a single line. As an example of its versatility, ISDN is used for transmitting images of operations for viewing and discussion by doctors and specialists in remote locations.
