在过去一年中通信技术的巨大成就表现在开始了以可接受的商用价格向单独用户提供更大的通信容量。特别应强调指出的有以下的几项:开始了用光纤维传送长途电话和电视业务。开始将直播电视服务送到美国的东北部和第一次在卫星通信中广泛地应用了K_U波段。低成本高性能卫星终端的可使用性将卫星通信服务直接地送到用户那里。在批准了IEEE局部区域网络标准的同时出现了低成本专用电话交换机(PBX),这就使计算机和其他设备之间的通信更加容易了。
The tremendous accomplishment of communications technology over the past year has been demonstrated by the increased availability of communications to individual users at an acceptable commercial price. In particular, the following should be emphasized: Optical fiber transmission of long-distance telephone and television services began. Started to deliver live TV services to the northeastern United States and for the first time used the K_U band extensively in satellite communications. The availability of low-cost, high-performance satellite terminals brings satellite communications services directly to the users. The emergence of low-cost Private Branch Exchanges (PBXs) along with IEEE local area network standards has made communication between computers and other devices easier.
