Abstract
PURPOSE:To execute a data transmission without interfering an exsisting register signal transmitting and receiving by adding one frequency to six frequencies of a frequency in a sound band to constitute the register signal of an R2 system. CONSTITUTION:To the functions of an outgoing register 5 and an incoming register 10, including six frequencies in an R2 system, 2100Hz as a forward signal and 420Hz as a backward signal are added and by the combined signal of this added one frequency and one frequency in exsisting six frequencies, codes 16-21 are expressed. In such a case, the code 19 expresses the starting of a data transmission, the code 20 expresses the request of the next data sending and the code 21 expresses the finishing of the data transmission Thus, data terminal 8 of an outgoing station 2 and a data terminal 13 of an incoming station 3 can execute the data transmission through the outgoing register 5 and the incoming register 10 without interfering the transmitting and receiving of an exsisting signal between stations.
