英国电信公司宣称,该公司计划建造一个供本国商业通信用的技术先进的光纤网络。该系统将被称作FACS(灵活通路系统)。网络将采用光纤而不用电缆,这样可提供大量的专用线路,开展宽带宽服务。英国电信公司已选定STC PLC公司和Northern Telecom公司为网络的主要供货商。合同的价值为1.7亿美元。元件的交货从1989年开始,预期网络于90年代中期竣工。Northern Tehcom公司和STC公司在美国和英国组建了一支200人的队伍,从事元件和网络的研制。 BT said it plans to build a state-of-the art fiber-optic network for commercial communications in its own country. This system will be called FACS (Flexible Access System). The network will use optical fiber instead of a cable, which provides a large number of dedicated lines and a wide bandwidth service. BT has selected STC PLC and Northern Telecom as major network providers. The value of the contract is 170 million U.S. dollars. Delivery of components began in 1989 and the network is expected to be completed in the mid-1990s. Northern Tehcom and STC formed a 200-person team in the United States and the United Kingdom to develop components and networks.
