After the eighth digit is recorded, block 6 simulates pressing button 17 in the name keyboard 7, and the remaining number characters are recorded in another memory cell of block 12. After recording the entire number, the subscriber presses button 18 in block 11 which puts this block in read mode. Then the subscriber picks up the telephone from the telephone dialer 5, block 6 of the coordinator and, having received the dial tone from the PBX,: SRI, named keyboard 7, pulse press button 19 (which corresponds to le 8, block 9 of the talk mode, shunt) - digit “8 - initial digit of dialing amateur relay 10, unit 11 for managing a long-distance national number” in the ten-day scale. block 12 of memory, opening the circuit 4.

The connection is working in the following way.

With a multiplied handset phone call, it may turn out that after dialing the aooparate, the signal from the analyzer output 2 blocks the decade keyboard 4 and prohibits the operation of generator 3.

The electronic dialer 5 translates the line “8” in line, and in block 6, from decadal keyboard 4, a signal is sent to exit the AMT.

The number “8 is missing free connecting lines to the automatic long-distance telephone station. In this, 2 allows dialing using decade keyboard 4 and removes the ban from generator 3. The signal from any key of decade keyboard 4 (except button 19) is fed to the input of the electronic dialer 5, which organizes the start signal of generator 3 and converts the digit code corresponding to the number of the button pressed in the pulse sequence.

This number recorded in the corresponding cells of the block 12 block will not occur, since receiver 1 will not receive the “Ready from AMTS” signal. At the same time, the caller receives from the telephone station the signal “Zahn then produces a release. After some time, it can repeat the long-distance call. To do this, it is enough to pick up the telephone set, receive a readiness signal from the PBX and press button 19 in the ten-day sequence goes to the impulse 8, which by its disconnecting contacts 13 translates the pulses into a line, and to block 9, which is animates conversational mode during inter-serial time to listen to PBX signals. From block 9, the signals arrive at the shunting neck of the relay 10, which, with its closure contacts 14, shunts the telephone when translating pulses into a line

Mathematical dialing will work according to the described algorithm, in which receiver 1 receives the signal “Ready from AMTS and sends a command to block 6, which provides automatic dialing as described for the primary long-distance call.

Block 6 coordination works as follows.

The device for automatic dialing in the mode "Long-distance communication" operates as follows.

The subscriber presses the button 15 in the block 6. At the same time, the block 11 is put into the recording mode. Block 6 provides an imitation of pressing the button 16 in the name keyboard 7, which leads to setting the starting address of the memory cell in block 11. The subscriber dials the required national number by

Mathematical dialing will work according to the described algorithm, in which receiver 1 receives the signal “Ready from AMTS and sends a command to block 6, which provides automatic dialing as described for the primary long-distance call.

Block 6 coordination works as follows.

The subscriber presses the button 15 "Long-distance connection, whereby a logical zero is fed to the input of block 11, which is set to the recording mode, and the trigger 20 is cocked in block 6. From the output of the trigger 20, the logical unit enters the input of circuit 21, (which eliminates the change the state of the trigger 22 when the button 19 is pressed in block 4). From another output of trigger 20, a logical zero is fed to the input of circuit 23 (which is

provides the opening of the transistor 27 to simulate pressing the button 16. At the output of the circuit 26, a logical unit appears, which enters the input of the circuit 32 and produces at its output a logical zero that triggers the one-oscillator 29. The latter generates a logical zero pulse, which, by opening the transistor 35 simulates pressing the button 17.

So in the electronic number20

provides translation permission; the signal 5 transmits the information of the sequence of dialing and recording of number characters from ten memory cells of block 12. Noise keyboard 4 through the circuit 23 to the counter Electronic dialer 5 (24 for counting their number) and To the input, one-to-one code combinations into pulsed transducers 25 assembled in circuits 26 and 34. Coding, i.e., provides for automatic- The single-oscillator 25 generates a pulse-15 set of the entire long-distance number.

The installation of the block 6 into the initial state occurs when the linear current is interrupted as a result of a tap, which is provided by a corresponding signal from the analyzer 2 arriving at the inputs of the flip-flops 22, 33 and the counter 24.

When organizing a local (intracity) communication, the subscriber dials any digit as the first character, except the number “8. Therefore, when any button is pressed in the dermo, the 25-digit keyboard 4 (except the button 19) is encoded through block 11 (the button 19) opens the transistor 28 into the memory cell 12. And the input of the Trigge capacitance of this cell allows 33 the logical zero arrives. Wherein

at the output of the trigger 33, a logical unit is set to prohibit the transmission of information from the decadal keyboard 4 through the circuit 21 to the input of the trigger 22, and the device for automatic dialing functions according to the described algorithm (local (intracity) communication).

Thus, the introduction of the coordination unit and the receiver of the “Ready pozvomogo zero” signal, which opens the transistor 27 in the nominal keyboard 7, which simulates pressing the button 16. This causes the device to automatically dial the number to write the first eight intercity characters to the corresponding memory cell Block 12. Next, the subscriber presses the corresponding buttons in the decade keyboard 4. This information enters the electronic dialer 5, in which

her eight digit numbers. Each time you press one of the buttons in the decade keyboard 4, a transistor 28 opens, which provides a transmission of a logical zero through pulse 23 to the input of the counter. These pulses are counted by a counter 24, and after counting eight pulses, a logical zero appears at its output. This logical zero triggers a one-shot 29 05 (assembled in circuits 31 and 36), which produces a logical zero pulse, opening transistor 35 in the named keyboard 7. This simulates pressing the button 17, therefore leaving the characters between the edges to get improved ergonomic device indicators for automatic dialing numbers by reducing the number of sensorimotor operations of the subscriber, as well as reducing the time of non-production, the three-person numbers are recorded in another job of the caller, as well as whith block 12.And linearly station at oborudyuvani

After recording the long-distance number, the subscriber picks up the phone and, after receiving the ready signal from the PBX, presses button 19 in the decade keyboard 4. Electronic dialer 5 in the decade keyboard translates eight pulses into a line. The signal from button 19 through
