摘要： 分析了传统的双绞线在实现数字传输技术中的难点和缺点,提出了采用时间压缩复用和回波抵消技术的新的全双工数字传输技术。这两种技术仍基于传统的双绞线,不仅降低了数据传输的成本,更重要的是使得普通双绞线用户也能实现数据的数字传输。

Abstract: This paper analyses the difficulty and disadvantage of the traditional twisted-pair applied in digital-transmitted technology and puts forward to the new digital-transmitted technology about full duplex adopting the time-compessed-multiplexed and echo-cancellation. The two sorts of technology still are based on tranditional twisted-pair,they reduce the cost of data-transmitted, and it is more important that the common twisted-pair comsumers can also carry out digital-transmission of data.
