Description

one

The invention relates to telephony and can be used to transmit voice messages both in real time and with a time shift.

According to the main auth. 507954, a device for transmitting and requesting voice telephone messages is known, containing terminal subscriber units connected to a co-speaker field with a central control unit, as well as memory blocks and reproducing addressed messages, autonomous indicator of the presence of stored voice message with control units, connected via switching field with a centrified source of signals for switching on and off indicators, in addition, the central control unit contains a register for counting The storage time of recorded voice messages is 1.

However, in this device, when there is no callee, the caller takes a lot of time to transmit information.

The purpose of the invention is to reduce the time of transmission of information to callers.

subscriber in the absence of the subscriber.

This goal is achieved by introducing an autoinformer and a unit for converting a number code into a voice message into a known device, the input and output of the autoinformer, as well as the inputs and outputs of the unit converting the number code into a voice message are connected to the corresponding additional outputs and additional inputs of the central control unit. block and switching field. In addition, the unit for converting the number code into a voice message is made in the form of a magnetic drum and reading units, through which the drum is connected to the central control unit and the switching field. The drawing shows a structural electrical circuit of the proposed device.

A device for transmitting and requesting voice telephone messages contains end devices: subscriber units 1, X1 each of which consists of a telephone set 2, a stand-alone indicator 3, a control unit 4, and a switching field 5, a central control unit 6, a centralized signal source 7, blocks 8 the memory and playback of the addressed message, the switching unit 9, the matching unit 10, the control unit 11, the unit 12 for converting the number code into a voice message, which consists of the magnetic drum 13 and the nodes 14, 14 -..., 14 schityyuan, and an autoinformer 15.. The device works as follows. In establishing a connection between two subscribers, block 6 provides the connection through the switching field 5 as it is done in a conventional telephone system.

If the connection failed (for example, due to the absence of the called subscriber), then the calling subscriber can use the system operation with a time shift. In this case, one of two situations takes place.

1. It is enough for the caller to send: to the called subscriber a recorded message and does not require receiving the answer of the called subscriber. In this case, the caller, in the receiver and received the readiness buzzer station, dials the service code and the number of the desired subscriber. The calling subscriber is presented with one of the free blocks 8 for recording the message, and the caller's device is sent a signal to turn on the atomic indicator 3, which then works autonomously until the callee time expires or the called subscriber requests the message addressed to him by dialing code of demand.

2. A call to a subscriber needs a conversation with the called subscriber in

form of dialogue, i.e. real time. In this case, the subscriber uses another service, called a callback order, that is, without resorting to either repeated calls or voice message recordings, inform the called party that the caller wants to talk to him as soon as The caller will be available, i.e. invite the callee to call the caller.

For this, the caller dials the code of this service and the number of the called subscriber. In this case, as a result of caller picking up the handset, unit 6 receives the corresponding signal and number of the calling subscriber (in electronic and quasi-electronic systems, this is always provided, and in the case of coordinates, the exchange must have the AON equipment installed). Block b starts searching for a free cell of the corresponding memory block and, having found a free cell, writes the number of the calling subscriber and the number of the called subscriber in it. Next, block b searches for a clear path through the switching field 5 to connect the centralized signal source 7 to the calling subscriber line. Along this path from signal source 7 to the device, a confirmation signal was sent by the telephone exchange to a callback order. As a result of receiving this signal, the autonomous indicator 3 of the caller's apparatus triggers for a short time. Thereafter, the connection with the caller is terminated, and work begins with the B1 callee. For this, the b block by the number of the called subscriber searches for the connecting path through the switching field 5 to connect to the line of the called subscriber a centralized source 7 of the on and off signal of the autonomous indicator 3, after which a short signal is sent to the subscriber devices 1 of the called subscriber, which includes its autonomous indicator 3.

Simultaneously with the sprinkling of this signal, the current time code is recorded in the call to the memory block cell in block b. Block b counts the time, periodically comparing information removed from the register in block b with the time information stored in the occupied memory cell in block b. If the called subscriber does not request the message intended for him for a certain time, the block b connects to his line through the found path in the switching field 5 a centralized source 7 of signals that sends a turn off signal of the independent indicator 3.

If the call time has not expired and the calling subscriber sees a working independent indicator 3

Claims (2)

{if the indicator is optical), and send {if the indicator is acoustic), it may request a message addressed to it stored at the station. To do this, he dials a special demand code, upon receipt of which unit 6 by the number of the called subscriber performs an associative search and selection of the contents of the memory cell in block b, in which the numbers of the called and called subscribers are recorded. Block b sends the caller's number to block 11, where it is recorded. Then block 11 searches in block 12 for free node 14 and transmits to it the number of the caller received from block b. Meanwhile, the block b searches for a clear path through block 9 and the switching field 5 to connect primarily the autoinformer 15, and then busy the node 14 to the called subscriber line, then sends a command to connect the path and sends the b connection signal to the autoinformer 1 Block 11 connects to the established spoken path, the free reference head of the autoinformer 15, from the winding of which to the line of the called subscriber is transmitted, the words Dial the number. At the moment of termination of the transmission of this message, block 11 starts up the occupied node 14 and connects its output to the line of the called aboneite instead of the reading head of the autoinformer 15, which is released. Node 14 converts the code of the number of the called subscriber received from block 11 into speech signals, which are transmitted to the office of the called subscriber following the newly transmitted trees. Dial the number. Thus, the message sent to the called subscriber may, for example, sound like this: Dial the number four-five-eight-six-two-one (if the network has six numbers for numbering). This composite message is repeated until the called party hangs up. Then he can pick up the phone again and, upon receiving a buzzer from the station, dial the number given to him, through which the device establishes a normal connection on a real scale; 5e lies. Thus, the proposed device saves the amount of equipment and, consequently, reduces the cost of the entire device. In addition, such a device is convenient for subscribers. Recording a message takes some time. It is much more simple to use .with the callback service, for which the caller need only dial the service code (one or two digits) and receive confirmation in receiving the order. Claim 1. Device for transmitting and requesting voice telephone messages by auth. 507954.0 tons of information, so that, in order to reduce the time for the caller to transmit information when there is no callee, an autoinformer and a number code converter are entered into the voice message, while the autoinformer has an input and output, and Also, the inputs and outputs of the unit for converting a number code to a voice message are connected to the corresponding additional outputs and additional inputs of the central control unit and the switching field. 2.
