【Abstract】 The balance interface at present is very difficult to support the full duplex transmision of baseband data in two twist wires.The anthors study and present a method in which the problem above can be solved by using a pair of Sender/Receiver.Now,this method has been used in some computer networks successfully.In this paper,the design idea and implementation,including hardware structure protocol design as well as performance analysis,are introduced in detail.Also,results of both testing and application in practice are given.更多还原
