The invention concerns data transmission method for implementing a transmission connection. The transmission connection comprises a transfer media (11) and transceivers (A, B) located at opposite ends of the connection. In the method the transceivers operate in time domain in consecutive cycles (T) each of which is composed of the following parameters: (a) a transmission interval (Tr) whose length corresponds substantially to the length of the burst to be transmitted, (b) a switching interval (t1) during which the transceiver switches from transmission interval to reception interval, (c) a reception interval (Rc) whose length corresponds substantially to the length of the burst transmitted by another transceiver, and (d) a switching interval (t2) during which the transceiver switches from the reception interval to the transmission interval. The propagation time &tgr; of the burst across the connection is determined before the transfer of payload data is started. To create an efficient transmission connection the parameters of the cycle (T) are selected so that they have the following relationship with the propagation time &tgr; of the burst:where T1 is the length of the burst in the first transmission direction and T2 the length of the burst in the second transmission direction, t1 is the switching time from transmission state to reception state, t2 is the switching time from reception state to transmission state, and T is the length of said cycle.
