The paper introduces an efficient and reliable fiber communicationsystem, which can implement milted virtual channels, point to point, full duplexcommunication by means of a pair of fibers.
Using the plesiochronous communication model, implement duplex audio communication functions on twain USB ISO endpoints, simplify the design of clock synch system.
Time Division Duplex (TDD) is a kind of duplex method of communicationsystem, by which uplink and downlink transmissions are time separated in mobile communications.
