However, the known device has a long line busy time. The purpose of the invention is to reduce the line busy time by limiting the number of outgoing lines. SISO. The goal is achieved by introducing a call receiving unit, a second OR element, a dialing number counter, a call delivery counter, a pulse shaper, and a delay element, the output of the power supply unit through the pulse shaper and the delay element being connected to the second input of the first the OR element, and the third output of the station signal extractor via the dial counter is connected to the first input of the second OR element, the output of which is connected to the fifth input of the program about the unit, and the fourth output of the station signal extraction unit is connected to the second input of the second OR element through the call arrival counter, the third input of which is connected to the second output of the relay unit through the call receiving unit. The drawing shows the structural electrical circuit of the proposed device. The automatic numbering block contains a named keyboard t, a software block 2, a relay block 3, a pulse generator k, a counter 5, the first block 6 matches, an encoder 7, a memory block 8, a switching block 9, a power supply block 10, the first (OR element 11, relays 12- time, block TZ for selecting station signals, trigger 1, second block 15 coincidence, block 16 receiving calls, second I / M element 17, count dial 18, counting 19 calls, form 20 pulses, delay element 21 , inter-serial time block 22, consisting of trigger 23 and decoder A. Automatic When the key of nominal keyboard 1 is pressed, the circuits of switching unit 9 are connected to the inputs of memory block 8 of the sequence specified by jumpers in the encoder 7. At the same time, the power supply unit 10 is turned on. The power bus receives the supply voltage, which simultaneously enters the input of the pulse shaper 20, at the output of which a quench pulse appears. The blanking pulse sets all the blocks back to their original state. At the same time, the latter is fed to the input of the delay element 21. The delayed pulse from the output of the latter through the first element OR 11 is fed to the input of software block 2, in the relay block 3 turns on a linear relay that connects the communication line to the input of block 13 of the signal-station selection. The readiness station signal (continuous beep) from the communication line enters block 13, where it is recognized, and from the output of the latter, through the input of program block 2, enters the input of the second block 15 coincidence, and from the output of the last in the relay block 3 turns on the relay-by-pass relay. At the same time, the pulse generator A is started. The rectangular pulses from the first generator output k (in the first half cycle) arrive at the input of counter 5 where they are summed, and from the second output (in the second half cycle) arrive simultaneously at the control input of the decoder 2 (unlocked) and to the input of the first block 6 coincidences through which they do not pass, since at the second input of the last at this time there is a inhibitory signal from the single output of the trigger 23. When recording into the counter 5 of the third pulse in the second half cycle, the trigger switches to the single state trigger 23. With one From the first output through the name pad 1 encoder 7 from the memory block B, the digit of the number series in the additional code, for example, the number two (additional code 1000), is written to the counter 5 from the first output. At the same time, the signal from the trigger 23 is fed to the second input of the first block 6, and this gives permission for the pulses from the generator C to the pulse Hoes of the relay of the relay block 3. Thus, after switching the trigger 23 to one, simultaneously with the recording of pulses into the counter 5, the line receives impulses from the relay block 3. Two clocks after switching to the trigger unit 23, a code 1010 will be recorded in counter 5 (ten}, which is decrypted in the second half cycle and a signal goes to the zero input of the trigger 23 L, switching the latter to the zero state. At the same time, the trigger I switches to the zero state, while the relay block 3 is turned off in the relay unit, since the inhibit signal is supplied to the input of the second block 15 coincidently with the single output trigger I , a signal is sent to the station's signal extraction unit 13. If at this time a line out signal is disconnected from the line, the output relay of the unit 13 is switched off by means of the program block 2 in the relay unit 3 and the relay 12 is started, which is set A certain time delay, through the first element OR 11, everything starts up again. When switching the trigger 23 (after testing the digit of the number to the zero state, the signal from the zero output of the latter switches to the second output of the switching unit 9, this circuit is prepared for recording from the memory block 8 of the code 11 of the second series, and from the single output of the trigger 23 block 22, a blocking signal arrives at the input of block 6. From this clock cycle, the pulses are delivered to the line, inter-run time is started and the line is monitored. In the eighth clock cycle {from the moment of switching to zero of the flip-flops 23 and in the counter 5, Write the code 0010, which decrypts and switches the trigger f to the unit state, which switches the shunt relay in the relay block 3, and sends an electrical signal to the input of the block 13. Next (the clock in counter 5 will be the OOP code, which will be decrypted and switched the trigger 23 is in the unit state, with the signal from the single output through the switching unit 9, the digit of the second series is recorded in the counter 3, and the permission for passing the series of pulses to the line and so on enters the second input of the first matching unit 6. After testing the last series of pulses, when a signal is received from the single output of the trigger 23 at the second input of the switching unit 9, with the signal through the next output of the last one, the contacts of the pressed key of named keyboard 1, the encoder 7 and the program unit 2 stop the generator. Thus, the generator works without stopping during the whole (cycle, synchronizing the operation of all blocks and circuit elements, and the trigger 1 between the pulse series turns off the shunting relay. This connection line is connected to the output of the unit 13 to control the communication line. After turning off the shunt the relay of the relay block 3 and the stop of the generator C, i.e. after dialing the number, the input of the block 13 remains through the linear relay of the relay block 3 connected to the communication line. Therefore, in the case of a line of communication, the signals of the station are transferred to the block 13, dd is converted into a signal that turns off the linear relay of the relay unit 3 and starts the time relay 12 for a specified time. At the same time, another output of the unit 13 is recorded in the dialing dial 18 unit 1. Turning off the linear relay of the relay unit 3 releases the subscriber line for an incoming call between the restartings of the dialer. At the end of the time delay from the output of the relay 12, the signal through the first element MJW 11 and the program block 2 turns on the linear relay of the relay block 3, which is occupied by with abonenska line, and the latter is connected to the input unit 13. When ready station input unit 13 receives a signal Ready dialing tone, through which the program unit 2 is started all over again. Likewise, shutdown and start is performed when the line is busy during the inter-serial time. The dialing number 18 counter is used to automatically activate the autodial when the line is busy. When a predetermined number of repetitions are reached by a signal from the output of counter 18 through the second element OR 17, the dialer is turned off.

The call send counter 19 performs the call send counting by a signal from the output of the counter 19 through the second element OR 17, the device is turned off.

In the intervals between automatically repeated inclusions the block

16 receiving calls remains connected to the line. When an incoming call signal comes from the output of block 16 through the second element And

17 all blocks are turned off. This prohibits the re-activation of the automatic number of probes from the started time relay 12. Thus, the proposed automatic dialer performs automatic monitoring of the line condition, switching off and repeated dialing the device when the line is busy during automatic dialing.

(during inter-serial time), automatic control and limiting the number of repeated calls when the line is busy, automatic control and limiting the number of sendings of the call when the subscriber stops sending, automatic control of incoming call. This makes it possible to reduce the time of establishing a connection with the called and calling subscribers, as well as by reducing the time taken to use the devices and the exchange, to reduce the connection time of other station subscribers.

Using the keys on a personalized keyboard to simultaneously turn on the power and start-up reduces power consumption, simplifies operation, and by reducing Tre | to heat modes, simplifies structures.
