Broad-Band Communication Systems in Great Britain

Great Britain, like other advanced countries, stands on the threshold of rapid changes in the local network driven by the twin forces of technological opportunity, which permit new network architectures and service capability, and demand for new services which can be flexibly and speedily provided. The paper first discusses the commercial and regulatory environment. The development of cable TV networks is then examined, particularly the more advanced forms of networks which support a wide range of interactive services such as videotex, photo videotex, and interactive video. Scenarios for telecommunications networks evolution are then outlined taking account of optical fiber systems and reliable VLSI circuitry developments. The two forms of network are compared and notable points of similarity are highlighted which suggest a natural convergence. Finally, some thoughts are presented on the possible nature of the network from this convergence.
