The invention relates to telecommunications, and can be used in transmission systems,

The purpose of the invention is to increase the amount of information transmitted.

Fig. 1 shows the structural electrical circuit of the device proposed in Fig. 2; 2 shows the structural electrical circuit of the control unit of Fig. 3, the electrical circuit of the switching unit;

The device for data transmission with switching of communication channels contains the first 1, second 2, third 3 and fourth 4 terminal information blocks, switching unit 5, control block b, element OR 7,, first 8, second 9 and third 10 elements And nerator 11 and communication channels 12-14. The control unit 6 comprises a decoder 15, the first 16, the second 17, and the third 18 flip-flops.

The switching unit 5 contains the first 19, second 20, third 21 and fourth 22 elements OR, the first-twelfth elements AND 23-34.

The device works as follows.

If the terminal information blocks 1 and 2 are in the active state NSH1, the terminal information block 3 is in the free state, then the terminal information block 1 is connected to the first communication channel, the terminal information block 2 is connected to the second, the terminal information block 4 is connected to the third, as a result, voice signals are transmitted over the first two channels, and the third — data i. After the transition of, for example, the terminal information block 1 to an idle state, the operator exposes a combination of 010 into the first, second and third inputs of the control block 6 tate in the output of the decoder 15, the control unit 6 is a signal that perebrasyyaet trigger 16 in a state in which at its first output is po- signal. This signal is supplied simultaneously to the first input element And 8 and the eleventh input of the switching unit 5. Element AND 8 opens, and the first - clock sequence is received from the first output of generator 11 through element OR 7 to receive data from final information block 4 and simultaneously to the eighth input of the block

5 switching. The signals from the eighth and eleventh inputs of the switching unit 5 open the elements And 23 and 24, resulting in; the inputs / outputs of the terminal information unit 4 are connected to the outputs / inputs of the first channel at the moments of arrival of signals of the first clock sequence in the information unit 4, i.e. at these times, data is transmitted to the first communication channel. Data is transmitted to the third communication channel under the influence of the combination 110, since the clock sequences are shifted relative to each other, the data is merged into both channels. Thus, knowing the law of loading communication channels by voice, one can determine the additional amount of data that can be transmitted through the proposed device to voice-free communication channels. So, when loading a device with speech, 5 this device can be loaded with data up to a value of p 0.8, taking into account the norms for time, delays (and up to 1 without those). As a result, the volume of information transmitted by the device is increased by a factor of 1.5-2 compared with lime. Invention Formula
