Description

one

The invention relates to communication technology and can be used for organizing dispatch communication or for communication at the control points of complex objects of automated control systems for decentralized connection establishment between abenents.

A device for group voice and tele single communication is known, which contains a frame synchronization unit connected through a distributor to the input of a switching unit, as well as a display unit, a control unit, a conversation unit and an OR element.

However, the known device does not provide prompt communication, since for each pair of multicore connecting cable only one connection is made using special equipment to find a free connecting line. In addition, it is not reliable enough.

The purpose of the invention is to increase the reliability and speed of communication establishment.

This is achieved by the fact that a speech conversion unit, voice and telecode memory blocks, a telecode information transceiver, and a receiving and transmitting unit are introduced into the device. The outputs of the switching unit are connected to the inputs of the voice communication memory unit connected to the speaking unit via the speech conversion unit and to the inputs of the memory unit of the telecode connection, the output of which is connected to the corresponding input of the memory unit of the telecode connection via the transceiver zi, the other input of which is combined with the inputs of the frame alignment unit, the speech communication memory unit and the monitoring unit and connected to the output of the matching receive and transmit unit, whose input through the OR element is connected to the output m storage unit voice communication, a memory unit telekodsvzy communication and frame synchronization block. The input of the display unit is connected to the output of the control unit, to the inputs of which an additional output of the switching unit and the corresponding inputs of the memory and telecode communication units are connected.

The drawing shows a structural electrical circuit of the device.

The group voice and telecode communication device contains a distributor 1 with voice communication outputs and outputs for transmitting telecode messages connected in pairs to the inputs of switching unit 2 consisting of switches 2i and call buttons 22 used for voice communication, as well as from switches 2z and call buttons 2.; used for telecode communication, display unit 3, consisting of signal lamps 3i, operating in voice communication, and signal lamps 82, operating in Telecode communication, control unit 4, consisting from collecting 5 and a circuit 6 for monitoring the status of time channels, a conversation unit 7, a speech conversion unit 8 consisting of a transmission unit 8i and a reception unit 82, a voice memory storage unit 9 consisting of a transmission unit 9i and a reception unit 92 , block 10 of the telecode memory memory, consisting of the lOi transmitting unit and the lOg receiving unit, the receiving and transmitting matching unit 11, consisting of the matching transmitting unit 11 and the receiving unit Ib, telecode information transceiver 12, the element "OR 13 , block 14 frame alignment, consisting of the transmission unit 14i, the receiving unit 142 and switch out. The device works as follows. Distributor 1 is triggered by a frame alignment pulse from block 14, and during its operation cycle generates control pulses of the start of time channels at its outputs. Each of the switches 2, 2z of the block “Ommutadia 2 has two inputs (odd and even) and four outputs (odd and even). Setting the switches 2, 2h to the upper position (see drawing) ensures that the corresponding subscriber is assigned to the dowager subscriber: their pairs of Time channels. In this case, the control pulses e of the odd outputs of the distributor 1 through the corresponding closed buttons 22, 24 are fed to the control inputs of the transmission units 9i and Yu and the control pulses from the even outputs of the distributor 1 are transferred to the reception blocks 92 and 102 of the memory blocks 9, 10. In the lower position (see drawing), switches 2i, 2z are mounted on pairs attached to other subscribers. In this case, the control units 9i and 10 receive control pulses from the even outputs of the distributor 1, and the reception units 92 and 102 - from the odd outputs. The selection of pairs of time channels for communication is carried out using call buttons 22, 24 having two inputs and two outputs. The signal lamps 32 of the display unit 3 are lit by signals from the outputs of the circuit 6 for monitoring the status of the time channels. Signals from the connecting line are fed to one of the inputs of the circuit 6 through the receiving block 1 b. The other input receives control pulses from the outputs of the distributor 1 through the collecting circuit 5. The coincidence of the signals arriving at the inputs of circuit 6 in a controlled time interval leads to the appearance of signals on the outputs of circuit 6 and the ignition of one of the signal lamps 32 of the corresponding pair of time channels . The ignition of the signal lamp 3i, 32 at the call button 2c), 24 pairs, attached to the given a6oHeHtoSd, signals that it has been called to communicate. Ignition of signal lamps 32 in other call buttons 22, 24 indicates that the corresponding pair of time channels, and therefore the subscriber to which this pair is assigned, is occupied. The control signals of the distributor 1 post. These 9, 10 and simultaneously from the odd outputs of the call buttons 22, 24 are fed to the inputs of the circuit 6 for blocking signals on the line input for the time of their transmission. The caller's signal lamp 32 will not illuminate until the callee a: customer responds, because the output of circuit 6, corresponding to the working pair of time channels, causes the signal to turn on the serial lamp 32, only when the circuit inputs 6, signals from the called subscriber and the distributor pair 1 are received simultaneously. The negotiating unit 7, together with the speech converting unit 8 and the voice communication memory unit 9, form the voice communication path, the transceiver 12 with the telecode communication memory unit 10 telecode vo1 | connection. Transmitted speech and telecode signals from the outputs of transmission units 9i and lOi arrive at the element OR 13 and through the matching transmission unit lli at the output of the device into the connecting terminal, and to the other subscriber. Control pulses from distributor 1 through switching unit 2 to blocks 9 and 10 program the process of recording and reading signals for a corresponding time interval at a high speed or a cycle at a low speed. In the voice path, the analog signal coming from the negotiation unit 7 is converted in the transmission unit 8i into a discrete sequence of pulses, which at low speed enters the transmission unit 9i. The control pulse coming from the distributor 1 to the control input of unit 9b allows counting high-speed accumulated pulses to be read into the communication line during the time of the time channel. The process of writing and reading telecode signals from transceiver 12 to the lOi transmission unit, proceeds as described. Discrete signals from the connecting line through the receiving receive block Ib are fed to the inputs of receive blocks 92, 102. These signals are recorded in receive blocks 92, Yua only if control pulses from the distributor 1 arrive at the control inputs of these blocks, moreover, recording occurs at high speed during the duration of the time channel, and reading at low speed during the cycle time. Synchronous operation of all sets of subscriber equipment is provided by unit 14,
