This invention relates to automatic telecommunications.

According to the main auth. No. 809649 is known an automatic call system for PBX subscribers, comprising a relay unit, a power supply unit, a switching field, a telephone set with a pulse relay, a pushbutton switch unit, a pulse sensor, a decoupling unit, And element, a pulse series distributor, a decadal block, a decoder, a block memory, valve block, output matching block, clock pulse generator, display block, program search block and receive block,

However, such a device provides low speed when establishing communication with mobile subscribers who are freely moving within the communication network, due to the fact that the search for mobile subscribers who freely move within the communication network is carried out by sequential dialing of subscriber numbers; combinations of which are recorded in the program search block. This leads to repeated sending of the call to the places of possible arrival of the mobile subscriber and reduces the speed of the device. In addition, the known device, if the mobile subscriber is located within the communication network by a subscriber number, the code combination of which is absent in the software unit, does not provide the possibility of establishing a telephone connection with it.

The purpose of the invention is to reduce the time of establishing communication with a mobile subscriber.

The goal is achieved by the fact that the automatic call system for PBX subscribers contains a relay unit, a power supply unit, a switching field, a telephone device with a pulse relay, a block of pushbutton switches, a pulse sensor, a decoupler unit, And element, a pulse series distributor , decoder, memory unit, valve unit, output matching unit, clock generator, display unit, program search unit and reception unit, a tone generator is entered

call, electronic time relay, inductor call receiver and electronic register, with an additional telephone set with a pulse relay connected to the linear input of the receiver of the inductive call and the output of the tone generator, the input of which is connected via an electronic time relay to the control output of the inductor call receiver, an additional output of the clock pulse generator is connected to the input of writing information of the electronic register, the output of reading information of which is connected to the first additional To the private input of the software search unit, the second additional input of which is connected to the first output of the inductor call receiver, and the second output and the first input of the inductor call receiver are connected respectively to the input and output of the electronic register.

The drawing shows a structural electrical circuit of the device for automatic calling of PBX subscribers.

The device contains a relay unit 1, a power supply unit 2, a switching field 3, a telephone set 4 with a pulse relay, a block of 5 pushbutton switches, a sensor of 6 pulses, a block of 7 decouplings, an element 8, a distributor of 9 series of pulses, a block of 10 decade keyboard, a decoder 11, a memory block 12, a distributor block 13, an output matching block 14, a clock pulse generator 15, an indication unit 16, a program search block 17, a reception bpock 18, a tone call generator 19, an electronic time relay 20, an inductor call receiver 21 and electronic register 22.

The device automatically call subscribers PBX works as follows.

Dialing the number of the called subscriber is performed by alternately pressing the buttons of the block of the 10 decade task. When the first button of the corresponding first digit of the number is pressed, the loop closes in the direction of the PBX and the power supply unit 2 is turned on. Decryphrato 11 converts keystrokes pressed on the keyboard, corresponding to the number of the called subscriber, into code combinations, which are recorded in memory block 12. After writing the code combination in memory 12, corresponding to the first digit of the number, the distributor block 13 is started, which alternately reads the code combinations of numbers of the called subscriber by parallel code from memory block 12, converts them into a series of pulses corresponding to the transmitted digits, and also sets the duration of the pause and inter-series time The series of pulses through the output unit 14 is received via the subscriber line to the PBX. Block 13, the distributors and the output block 14 are controlled by pulses generated by a highly stable generator of 15 clock pulses. When the mobile subscriber is located within the communication network, by the subscriber number, the code combination of which is absent in the program search block 17, it is necessary to record it in the program search block 17 in order for the mobile subscriber to establish a connection with the mobile subscriber. I would have rubbed on. To make a correction in block 1 of the software search about its new location, the mobile subscriber dials a special index and subscriber number of the automatic telephone subscriber device assigned to him at the telephone set of the telephone set. The PBX recognizes the code of the subscriber line in the state of the call, decrypts and remembers. Then the information received from the mobile subscriber is analyzed and the control connection between the telephone station auto subscriber and the PBX is analyzed. ATS sends ringing signal. The inductor call plates are received by the inductor call receiver 21. Through receiving the inductor call, an electronic time relay 20 triggers, which turns on the tone call generator 19, and within 2-3 seconds (84 times the operation of the electronic time relay) a tone signal is sent along an additional subscriber line towards the PBX. At the same time, the electronic register 22 is connected to the additional subscriber line of the automatic calling system of the ATS subscribers, and the Reset signal to the initial state of the first memory line is written to the program search block 17 to record the subscriber number code combination corresponding to the location of the mobile subscriber currently on the network . The tone signal transmitted in the direction of the PBX controls the reading of the pulses of the direct current of the subscriber number code over which the mobile subscriber is currently located. The electronic and tron register 22 connected to the line receives and records the digits of the subscriber number to be recorded in the program search block 17. Upon completion of recording the subscriber number in the electronic register 22, the latter generates a dialing end signal to the inductor call receiver 21, which disconnects the electronic register 22 from the subscriber line. After the electronic register 22 of the dialing number signal is read, the recorded information is read from it and this information is written on the first line of memory of the program search block 17. Since the proposed device provides an additional entry in block 17 of the software search for the code combinations of the subscriber number at which the mobile subscriber is currently located, several additional attempts to establish a connection to the mobile subscriber to their intended locations are excluded. Thus, the time to establish a connection with a mobile subscriber is reduced by reducing the number of attempts to establish a connection to the mobile subscriber.
