Description

 The invention relates to telecommunication technology, in particular, to the field of transmission in pauses of speech of other information on the telephone path formed through the connecting paths (cord sets) of the switching station.

 A relatively large number of inventions are known that are devoted to the detection, isolation, and compression of speech pauses transmitted by a non-switched telephone path with other information.

 At the same time, the advantages of speech pause compression devices with other information can be used to the greatest extent when transmitting voice and other information accompanying it via a telephone path formed through a fully accessible bundle of connecting paths, in particular through cord sets of an automatic switching station. With a large number of fully accessible connecting paths, the throughput of the telephone path due to the compaction of speech pauses can be increased up to two times.

 This position is especially relevant for automatic telephone stations, in the cord sets of which are included expensive speech-converting devices (vocoders).

 A long-distance automatic telephone exchange is known that contains AK subscriber sets (by the number of connected subscriber units), the outputs (inputs) of each of the AKs are connected to the corresponding inputs (outputs) of an analog (subscriber) switching field (AKP), the outputs (inputs) of which are through cord sets (ШК), each of which is attached to a speech-converting device (RPU), connected to the inputs (outputs) of a pulse (channel) switching field (ICP), the outputs (inputs) of which are the outputs (inputs) of the ATS DS, and The incoming inputs (outputs) of the automatic gearbox and ICP are connected to the corresponding outputs (inputs) of the control device.

 According to the circuit of FIG. 1, the output of telephone apparatus 1 (colloquial devices of a subscriber terminal device), located at point A (B), is connected through the delay line 2 to the first input of the first electronic key 3. The output of telephone apparatus 1 is also connected to the input of voice control device 4 (УУГ) the output of which is connected to the second input of the first electronic key 3 and in parallel with the second input of the subscriber set 5 of the switching station.

 The third input of the first electronic key 3 is connected to the output of the digital information transceiver 6, the input of which is connected to the first output of the second electronic key 7, the second output of which is connected to the input of the telephone set 1.

 The output of the first electronic key 3 is connected to the first input of the subscriber set 5, the first and second outputs of which are respectively connected to the first and second inputs of the second electronic key 7.

The first input of AK 5 through the corresponding outputs of the analog (subscriber) switching field 8 is connected to the first input of the first block 9 ₁ bypass, and the first output of this block is connected to the input of the transmitting branch of the vocoder 10, the output of which is connected to the second input of the first block 9 ₁ bypass, and the second output is connected to the corresponding input of the pulse (channel) switching field 11 and in parallel with the output of the sensor 12 inverted pause combination, the input of which is connected to the second output of the automatic transmission 8 and in parallel to the third input of the first block 9 ₁ bypass of the transmitting branch of the vocoder.

The output of the IKP 11 ATS, located at point A, through a communication channel (CS) 13 is connected to the corresponding input of the IKP 11 ATS DS, located at point B. The output of this IKP is connected to a parallel connected first input of the second block 9 ₂ bypassing the receiving branch of vocoder 10, the first input of the decoder 14 of the non-inverted pause combination of the vocoder 10, and also to the input of the receiver 15 of the inverted pause combination. The first output of the bypass block 9 _{2 is} connected to the input of the receiving branch of the vocoder 10, the output of which is connected to the second input of the bypass block 9 ₂ and through it to the third input of the ACP 8, the fourth input of which is connected to the output of the receiver 15 of the inverted pause combination connected in parallel with the fourth input the second block 9 bypass, the third input of which is connected to the output of the decoder 14 non-inverted pause combination of vocoder 10.

 The third output of the ACP 8 through AK 5 is connected to the first input of the second electronic key 7, the second input of which is connected to the fourth output of the AK 5. The first output of the electronic key 7 is connected to the input of the PDDI 6, and the second output to the input of the telephone set 1, located at point B .

 The inputs of analog 8 and pulse 11 switching fields are connected to the corresponding outputs of the control device 16 (UE).

 Similarly, the inverse branch of the information path is formed from point B to point A.

 The device operates as follows.

In the absence of voice transmission from the output of the vocoder 10 located, for example, at point A, a pause combination is transmitted, which at point B is received by the decoder 14 of the non-inverted pause combination. The output of block 14 gives the potential of logical zero, which is fed to the third input of the second block 9 ₂ bypass. Due to this, at point B, the receiving branch of the vocoder 10 is disconnected from the communication path. Due to the presence of zero potential at the second input of the second electronic key 7 at step B, the input of PPCI 6 and the input of the telephone set 1 are turned off.

 In this mode, on the transmitting side of the path (point A), the zero potential of logical zero is fed from the output of the UGF 4 to the second input of the first electronic key 3, as a result of which the output of the telephone 1 is disconnected from the information path and the output of PPCI 6 is connected to it.

At the same time, the zero potential of logical zero through AK 5 and AKP 8 is fed to the third input of block 9 bypassing the transmitting branch of vocoder 10 and it is disconnected from the communication path, and therefore, transmission of the pause combination is stopped. At point B, bypassing the receiving branch of vocoder 10 is provided as a result of the potential coming from the output of the decoder 14 of the non-inverted pause combination to the third input of the bypass block 9 ₂ .

Although when the transmitting branch of the vocoder 10 is disconnected from the communication path from the side of point A, the supply of the non-inverted pause combination is stopped, at step B, the receiving branch of the vocoder 10 is bypassed through block 9 ₂ , since it is fixed in this state until the signal of the change in the operating mode of the path is received.

 Thus, in the absence of voice transmission, the corresponding direction of the telephone path is ready for the transmission and reception of digital information.

 With the beginning of the transmission of speech, for example, at point A, the voltage of the speech signal comes from the telephone set 1 located at point A, from its output to the input of the voice control device 4. The same voltage through the delay line 2 for a time of about 50 ms is supplied to the first input of the first electronic key 3. From the output of the voice control device 4, the potential of the logical unit is supplied to the second input of the first electronic key 3, the second input of the subscriber set 5 and then through the automatic transmission 8 to the input of the sensor 12 inverted pause combination and to the third input of block 9 bypassing the transmitting branch of vocoder 10.

Under the action of the control potential supplied to the third input of block 9 ₁ , the transmitting branch of vocoder 10 is connected to the communication path. In addition, for an order of 50 ms, an inverted pause combination is supplied to this path from the output of the sensor 12. Through IKP 11 of point A, communication channel 13 and IKP 11 of point B, this code sequence is fed to the input of receiver 15 of an inverted pause combination, the output of which is the potential of a logical unit, to the fourth input of block 9 ₂ bypass and through its contacts to the information path is connected to the information path the vocoder branch 10. At the same time, the potential of the logical unit is supplied to the second input of the second electronic key 7 from the second output of the ACP 8 through the AK 5, as a result of which the input of the PPC 6 is disconnected from the information path and li ne thereto entrance telephone set 1 placed on the point B. After approximately 50 ms subscribers, between which a connection is established, starting to listen to talk each other.

 When there is a pause (break) in speech from the output of the transmitting branch of the vocoder 10, located, for example, at point A, the non-inverted pause combination begins to enter the information path, which is received by the decoder 14 located at point B.

 Under the influence of the potential of logical zero coming from the output of the decoder 14 of the non-inverted pause combination of vocoder 10 to the second input of the automatic transmission 8, the zero potential also appears at the second input of the second electronic key 7. As a result of this, the input of PPCI 6 is disconnected from the information path and the input of telephone apparatus 1 located at point B is connected to it.

 Switching off the transmitting branch of vocoder 10 at point A occurs under the influence of zero potential coming from the output of voice control device 4 to the second input of AK 5 and then to the third input of bypass block 9.

 The output of PPCI 6, located at point A, through the established connection is connected to the input of PPCI 6, located at point B.

 The required connection between the subscribers located at points A and B is established in accordance with the dialed number (address) for the commands received from the device 16 of the control.

 Synchronization of PPCI 6, located at points A and B, and the exchange of digital information between them are provided by known methods.

 The capacity of the well-known automatic telephone exchanges of long-distance communication, even with the optimal structure in terms of classical representations, is far from being fully utilized.

 This is due to the fact that approximately 50% of the time falls on pauses and interruptions in speech, which are not condensed by the transfer of other information.

 This gap is eliminated with a relatively small amount of additional equipment to the switching station and low material costs.

 In the proposed technical solution, due to the use of a six-wire subscriber switching field, there are no difficulties with the performance of the station control device, the structure of its software remains unchanged, and basically the control system’s design and structure are almost unchanged compared to the prototype.
