Claims (4)

outgoing telephone messages consist of the caller sprinkling the Codes of the service request signal, recording the callee number, recording the voice message while remembering the recording time, sending the signal to the called subscriber about the presence of the stored voice message, storing it on the side of the called subscriber, making a connection to call service request code signal, playback of a simple voice message, and cancellation of a notification signal after a predetermined about storage time. The proposed method can be implemented using a device whose structural electrical circuit is shown in the drawing. A device for implementing a method for transmitting a voice call request includes terminal subscriber units 1, each of which consists of a telephone set 2, a stand-alone indicator 3 of the presence of a stored voice message, for example, optical, with block 4, a control signal and switching off of indicator 3, connected to the commutation field 5 with a central control unit 6, including register 7 for counting the storage time, recorded voice messages and memory blocks 8. Terminal user devices va 1. through the switching field 5 are connected to the centralized source 9 of the on and off indicators 3, the device also contains blocks 10 of the memory and playback of aapecoBanHQro voice message, the switching unit 11, the matching unit 12 and the unit 13 controlling the units 10. The device works as follows When the device operates in a time-shifted mode, the caller dials a special service request code and then receives a service call buzzer when the handset's telephone handset 2 is picked up and the readiness buzzer is received. p required subscriber ta. In this case, as a result of the caller picking up the handset, the central unit 6 receives the corresponding signal and the caller's number with the dialed code and issues to block 13 a command to search for the free unit 1O. The first unit 6 starts searching for freedoms} of the corresponding memory block 8. Found the free unit 10, the central unit 6 starts searching for a free path through the switching field 5 to connect the found unit 10 to the other party’s call line. Daleui central unit 6 records in the found memory unit 8 the dialed number of the called subscriber, the number of the found unit 10, dialed by the caller, and the memory of the memory unit 8 is marked, and then issues a command to the switching field 5 to terminate the path between the found unit 10 and the calling line the subscriber, as well as the command through the block. 13 to turn on the mechanism that records the found block 10, and to the path through the terminal 11, then from the found block 10, a signal is issued to allow the calling subscriber to start saying a message, which is recorded in the same block 10. After the end; The signal is sent to the calling subscriber, the telephone station confirms the reception of a recorded message for storage, which is fed from the centralized source 9, as a result of which its indicator 3 is triggered. After that, the connection with the caller is closed. The work with the subscriber is completed and started. For this, the central unit 6, based on the called subscriber number recorded in the memory unit 8, searches for the connecting path through the switching field 5 to connect the centralized source 9 of the turn on and off indicators 3 signals to the called subscriber line, after which a short signal is sent to the subscriber unit 1 of the called subscriber, including him and. Indicator 3; Simultaneously with the sending of this, the current time code is recorded in the occupied call of the memory block 8, and the central unit 6 keeps track of time, periodically comparing information taken from register 7 with time information stored in memory 8. If the called party does not request the message intended for him for a certain time, then the central unit 6 connects to his line through the found path in switching box 5 from the centralized south emitter 9, the indicator 3 turns off the signal 3. In case the call time has not expired, to receive the recorded message, the called subscriber dials a special code, which in the central unit 6 Sampling the memory block 8 is generated, in Kotopo i the number of the occupied space 1O is recorded, and according to this number and the number of the called subscriber the central block b searches for free paths through the block 11 and the switching field 5 and issues a command to terminate the path and start the mechanism to play maintain the unit 10. When operating in real time when one subscriber calls another, the central bpoc 6 provides the connection through the switching field 5 as it is done in a conventional telephone system. The i.Cnoco6 claim is for transmitting and requesting voice telephone messages, including sprinkling the service request code with the caller, recording the called party number, recording the voice message, establishing a connection with the called subscriber, and playing back the recorded voice message, characterized in that, in order to reduce the number repeated calls, after recording the voice message, a signal is sent, notifying that there is a stored voice message, it is remembered on the side of the called subscriber, call is connected by the request signal code of the service of the called subscriber, VC 11: 1 OPI T he voice over voice with the second ii cancel the notification signal, 2. The method according to claim 1, characterized in that, simultaneously with the recording of the voice message, the memory recording time is recorded. The C and the notification signal are canceled after a given storage time has elapsed. 3. A device for carrying out the method according to claim 1, comprising terminal stations connected to a switching -ty field with a central control unit, as well as memory blocks and reproducing the addressed message, characterized in that it enters the terminal installations. Autonomous indicators of the presence of stored voice message with control units, connected via a KOMMYTcTjunoHHoe field with a centralized source of signals for switching on and off the indicators. 4. The device according to claim 3, characterized in that a register is entered into the central control unit for counting the storage time of the recorded voice messages. one El
