(Ls

The invention relates to automatic telecommunications and can be used as a subscriber device for receiving and displaying information about a caller's number and transmitting information about a private number by a multi-frequency method.

A device for automatic dialing is known, containing a serially connected named keyboard and a number programming unit, a series and pulse counter whose output is connected to another input of the number programming unit, and also a prohibition element, a bistable element, a serial time sensor, a multi-frequency generator, a block. indication and decadastatur, while the output of the nominal keyboard is connected to the first input of the bistable element, the output of which is connected to the first input of the pulse series counter, At the decade and nominal keyboard and serial sensor input, the first output is connected to the second input of the pulse train, and the second output is connected to the input of the bar element, the output of which is connected to the output of the ten-day keyboard and connected to the input of the multi-frequency generator connected to the unit indication, with the first output of the number programming unit connected to another input of the prohibition element, and the second output to the second input of the bistable element 1.

However, this device does not provide callers with information about the caller’s number after serving with PBX devices, therefore does not reduce the number of repeated calls: it does not have sufficient speed.

The purpose of the invention is to reduce the number of repeated calls.

The goal is achieved by the fact that the inductor call receiver, the delay line, and the launch unit on the own number auto-dial, the output of which is connected to the first input of the bistable element, as well as the receiver of test call sets, are entered into the device for automatic dialing. which is connected to the input of the inductor call receiver and the output of the multi-frequency generator, and the output is connected to the input of the trigger unit to the autodial of the own number.

The drawing shows the electrical structure of the device for automatic dialing.

The device for automatic dialing contains a named keyboard 1, Number programming unit 2, counter 3 series of pulses, an element. 4 prohibition bistable element 5, sensor 6 serial. Time,

multi-frequency generator 7, display unit 8, decade keyboard 9, receiver of inductor call 10, delay line 11, receiver of 12 call test messages, block 13 of launching an autodial of its own number.

The device works as follows.

in a way.

When pressing the button of personal keyboard 1, the bistable element 5 moves from the initial to the working position, the signal from which, in order to avoid malfunctions, the personal computer 1 and the ten-day keyboard 9 are blocked, the sensor 6 is turned on, the counter 3 is enabled. 2 will go to one of the inputs of element 4.

To the second input of element 4, the signal is fed from the output of sensor 6. When this is done at the output of element 4, a signal is received that will start the multi-frequency generator 7 to dial the first two-tone series according to the program installed in block 2 for this series.

The two-tone parcel from the multi-frequency generator 7 is transmitted to the line and to block 8, which generates an acoustic signal, under-: the confirmation set of the first series.

After the end of the serial time produced by the sensor b in the form of a rectangular pulse of the appropriate duration, the signal at one input of the multi-frequency generator 7 stops, which then turns off and stops sending the two-tone signal to the line and block 8. In addition, after the end of the serial time, sensor 6 will switch the counter 3 in the second position. After a short delay, the sensor 6 generates a rectangular pulse with a serial time duration and sends it to one input of element 4, to the second input of which a signal is fed from the output of counter 3 through block 2. In this case, the multi-frequency generator 7 turns on the production of the second two-series series, respectively, ijc program, installed in block 2. The two-tone parcel enters the line and block 8, in an antiscogy manner providing a set of subsequent series.

After the last series has been dialed, the counter 3 will go to the dialing end state and, through block 2, will issue a command to the jpcraHOBKy device by moving the bistable element 5 to its original position. The lock from nominal keyboard 1 and decade keyboard 9 j is removed, and the device enters the state ready to tastaturnomu or automatic dialing. The keyboard dialing is performed using the decade keyboard 9, which directly activates the multi-frequency generator 7 .... After dialing the number on the keyboard 9 or the name of the device 1 on the calling subscriber unit 8, the number of the called subscriber will be displayed. At the PBX, the control device, having received the address information, will establish the appropriate connection. With the PBX, the called subscriber will be provided with a signal of an inductor call; (AC signal with a frequency of 25 Hz, voltage 80-120 V, duration 1 with a pause between the 4 s parcels / and control of the call to the calling subscriber synchronously with the signal of an inductor call. First check a; the call is sent by the receiver 12, which forms at its output a command transmitted to the input of block 13. Block 13 will transfer the bistable element 5 and block 2 from the initial state to the working state as well, as was done by pressing one of the buttons named tattoo 1. With the output signal of the bistable element 5, in order to avoid failures, the name keyboard 1 and decade keyboard 9 is blocked, the sensor 6 is turned on and the work counter is enabled 3. The signal from counter 3 through the block 2 prepared for operation goes to one of the element inputs 4. To the second input of the element 4 signal: the signal is fed from sensor 6. At the same time, the output of element 4 is a signal that triggers a multi-frequency generator 7 to dial the first two-tone series according to the Program installed in block 2 for this series (block ke 2 along with frequently called subscriber numbers is programmed in the usual way with the user's own subscriber number of the device for automatic dialing /. The two-tone parcel from the multi-frequency generator 7 is transmitted to block 8 and to the box. Block 8 will display this series. After the end of the serial time produced by the sensor b in the form of a rectangular pulse corresponding to a long tee (30-50 ms), the signal 1 on the output of the multi-frequency generator; pa 7, which turns off at the same time, stops sending the two-tone signal to the line and block B. After the end of the serial time, the sensor 6 moves the counter 3 to the second position. After a short delay, for example, 5 ms, the sensor 6 generates a rectangular pulse with a serial time duration and sends it to the input of element 4, to the second input of which the signal is fed from the output of counter 3 through block 2. At the same time, the multi-frequency generator 7 is turned on to produce the second two-tone series, respectively, to the program in block 2. The two-tone parcel arrives on the line and block 8, in which the second series of the called subscriber number is displayed (the second series of the own number). Similarly, a series of subsequent series is provided. After dialing the last series, the counter 3 enters the state of ending the number and, through block 2, provides the command to stop the device by moving the bistable element 5 to the initial state. Thereafter, the lock is removed from the nominal keyboard 1 and the decade keyboard 9 and the device completely returns to its original state. Thus, 7-0.05 + 6-0.005 0.39 seconds will be spent on the transmission of information about your own number, i.e. less than 0.5 s. Consequently, the caller's own code with a large time reserve will be transmitted to the terminal of the called ... subscriber during the pause between the calls, Tak as the pause between the sends, even in the worst case, cannot be less than 3 seconds. In the mode of receiving a call, the device works as follows. The signal is received by receiver 10, which converts the sending of an alternating current of 25 Hz with a voltage of about 80 V into a DC pulse with a duration corresponding to the duration of the sending of alternating current. At the falling edge of this pulse, a short pulse is generated at the output of receiver 10, which is transmitted through a delay line 11 by 1 second to the input of block 13. A delay line 11 by 1 second is entered for to delay the start of block 13 in order interfere with the process of receiving information onomer caller. As pokazano above, the information about the caller's number is transmitted immediately after receiving the first control call. Within 1 second, the block will display information about the number of the caller. subscriber with a large margin, because. the transmission time of this information does not exceed 0.4 s. After 1 s signal

from the output of the delay line 11 will be received by the displayed block 8 when dialing the jHa block 13. This will cause a measure of the called subscriber. If the device input of the called subscriber is about the number of the called abon, the dialing of its own number, nent, displayed when dialing

which will be done in the same way, after the first test message

as the dialing of your own call-5 number will match, then the PBX is correct;

The other subscriber who has set up the connection,

earlier. After receiving information about the number of the proposed device allowing the called subscriber, the caller will reduce the number of repeated calls. The subscriber compares it with the information of calls.
