Abstract:
A data transmission method for a bidirectional transmission connection, the transmission connection comprising a transfer medium and transceivers located at opposite ends of the medium, the method comprising the steps ofusing the transceivers in time domain in consecutive cycles, each cycle being composed of the following parameters:(a) a transmission interval whose length corresponds substantially to the length of the burst to be transmitted,(b) a switching interval during which the transceiver switches from the transmission interval to reception interval,(c) a reception interval whose length corresponds substantially to the length of the burst transmitted by another transceiver, and(d) a switching interval during which the transceiver switches from the reception interval to the transmission interval,determining the propagation time .tau. of the burst across the transmission connection before transmission of payload data is started, andselecting the parameters of the cycle so that they have the following relationship with the propagation time .tau. of the burst: ##EQU4##where T1 is the length of the burst in the first transmission direction and T2 is the length of the burst in the second transmission direction, t1 is the switching time from transmission state to reception state, T is the length of said cycle, and n is a number from the set {0, 1, 2 . . . }.
