Data transmission method, data transmission apparatus and data transmission system using this method

摘要

A data transmission method includes a step of dividing each data into two or more low-speed data so as to create two or more sequences of low-speed data which are separated by no-signal intervals, a step of adding a fixed pattern for detecting a head or an end of each low-speed data included in each of the two or more sequences of low-speed data to each of the no-signal intervals included in each of the two or more sequences of low-speed data so as to create two or more sequences of fixed-pattern-added low-speed data, and a step of transmitting the two or more sequences of fixed-pattern-added low-speed data to the transmit station connected to the other network.
