Description

The invention relates to a telephone communication technique, and can be used in telephone sets and is an improvement of the technical solution by the author. St. No. 1635279.

The purpose of the invention is the realization of the possibility of accessing a long-distance telephone network.

The drawing shows a structural electrical diagram of a dialer for a telephone set of internal telephone networks intended for domestic and long-distance dialing of three, four, five, six, seven and twelve-digit numbers.

The dialer for the telephone of the internal telephone network contains an embedding unit 1, a dialing unit 2, a control and switching unit 3, a one-shot 4, a generator of 5 pulses, a dialed digit block and display units 6, a relay 7, the element OR NOT 8, the first block 9-1 re-issuing the first digit, second block 9-2 re-issuing the first digit, re-dialing block 10, first digit dialing block 11, first key block 12-i, second key block 12-2, differentiator 13, first block 14-1 select the type of set, the second block 14-2 select the type of set ora

The dialer for the telephone of the internal telephone networks operates as follows.

Consider the case of dialing a three-digit number. The subscriber sets the key 12 select the number of characters in the set in the dial position of a three-digit number. The first and second blocks 14i and 142 of the selection of the type of set are transferred to the intracity dialing position, i.e. up to seven characters; the inclusion of a micro-switch (not shown) provides power to the electronic dialer circuit.

The impulse (+) that passed through the zeroing block 1, zeroes the control and switching unit 3, the same impulse envelopes all the fixation and indication blocks of the dialed digit 6. Now on all the digital indicator lights in blocks 6, the figure O will light up.

To dial the first digit, the subscriber performs the first press and release of the dial button 2.

A pulse (+) through dialing unit 2 passes to block 3, and a signal appears at its first output.

1 at the first output of block 3 will turn on the relay 7, the closing contact of which will connect an additional capacitor with a capacity of 1 microfarad during the master circuit of the generator 5. The generator 5 will begin to generate with a frequency of 1 Hz.

The same 1 from the first output of block 3 enters block 6, where the first digit of the set is formed.

With this signal present, each pulse from the generator 5 at a frequency of 1 Hz is summed up in block 6, which is accompanied by the flashing of the numbers O, 1, 2 on the indicator, etc.

After the number 9, a decimal point appears, which means the number 10.

After the figure appears on the indicator light, the block 6i automatically zeroes, then the sequential summation of the pulses from the generator 5 resumes.

The subscriber monitors the count of numbers on the indicator of the block 6i. As soon as the first light appears, he needs a dialing digit, he immediately makes a second press and releases the dialing button 2.

Impulse (+) through block 2 passes into block 3, which causes a transition 1 from its first output to the second.

Since the signal disappeared from the third input of block 6i, the latter stopped counting the generator 5 pulses.

The second and third digit numbers are dialed in the same way.

As soon as the third is lit up, the dialing digit on the third digit indicator is needed, the subscriber will immediately make a fourth press and release button 2.

5Accordingly 1 will move from the third

on the fourth exit from block 3.

Even before the start of the set, having determined its three-digit nature, the first and second blocks 12-i and 12-2 keys are set to the appropriate position. This position is associated with the fourth exit from block 3, so 1 from this exit through the first block 12-1 of keys goes to the input of the differentiator 13, and from its output to the third input of block 3, that

5 calls the self-propelled movement 1 from the fourth exit down to the thirteenth output of block 3, where 1 will stop, since this output does not have a communication circuit.

The self-propelled plane 1 is explained by the fact that, having arrived at any of the outlets 4, 5, ... 12 of block 3, it is due to the construction of blocks 12-i, 12-2 keys: it switches to the output of the latter and then to the differentiator 13, to the third input of block 3, which causes its transition

5 from the output to the output, up to the interruption of the specified link through the first key 12-i.

Making sure that the first three lights indicate that the correct digits have been dialed, the subscriber removes the handset from the lever of the telephone, listens to the phone, makes sure that the PBX is free, then makes the fifth press and release of the button 2, as a result of which the digital parcels will be automatically issued dialed number in the telephone network.

After leaving 1 from the twelfth output of unit 3 on the thirteenth output, relay 7 turned off. The relay contacts disconnected the capacitor with a capacity of 1 microfarad during the master circuit of generator 5, but the capacitor with a capacity of 0.1 microfaram remained in this circuit, so generator 5 began to oscillate with frequency 10 Hz. However, its oscillations do not have an output, since there is no signal on any of the blocks 6 at the third input.

As a result of pressing and releasing button 2, transition 1 from the thirteenth to the fourteenth exit of block 3 occurred.

0 This same 1 will go to the fourth input of block 6i, where its appearance will allow receiving pulses from generator 5, but these will be pulses with a frequency of 10 Hz. Only now, in block 6i, the pulses are not summed, but subtracted. The subtraction process is viewed on the indicator of the first digit of the set.

While 1 is at the fourteenth exit from block 3 (the same can be said about all outputs up to 25) through the diode

all the time will be on duty (+) on one of

inputs to the circuit 2I-NOT 8, so the pulses (+) of the subtraction will be transmitted from blocks b through the circuit 2I-NOT 8.

The end of the process of subtracting the first digit from the reversible counter 6i is recorded by potential (+) at the first output of block 62, which, through the closed disconnecting contact of the first block 9-1, translates 1 in block 3 from the fourteenth output to the fifteenth, and also includes the one-shot 4, which temporarily prohibits the operation of generator 5 in order to create a pause between digital transmissions to the telephone network.

After the operation time of the single vibrator 4, the generator 5 will again begin to emit pulses with a frequency of 10 Hz. Only now the subtractive pulses arrive at block b2 of the second digit of the set, due to the fact 1 at the fifteenth output of block 3 and the closed contact of the second block 14-2 of the dial type selection. The issuance of subsequent digits to the network is done in the same way.

Upon completion of the issuance of the third digit in block 3 1 will switch from the sixteenth exit to the seventeenth, but since the second key block 12-2 is set to the position corresponding to the three-digit number set, 1 will arrive at the output of the second key block 12-2 and result in block 3 initial state. The figure O will be displayed on all indicators.

The dialer has returned to its original state.

As soon as the conversation with the called subscriber is started, the micro-toggle switch should be removed from the dialer circuitry.

In order to speed up the dialing of numbers 6, 7, 8, 9, and 10, the dial speeding button 11 is inserted, which allows every time before the dialing of the specified numbers to be written down in the corresponding block 6 a number 4 so that it starts with the number 5.

To dial the seven-digit number, the subscriber presets the first and second blocks 12-1 and 12-2 of the keys to the corresponding position. A dialing order is similar to a three-digit set, but it lasts until all seven numbers have been dialed. After dialing the seventh digit 1 in block 3, the eighth output is automatically through the first block 12-i of keys and the differentiator 13 will go to the thirteenth exit from block 3 by self-driving. issuing the seventh digit.

For dialing a twelve-digit subscriber, the first and second blocks of keys 12 are set to disable their inputs from the outputs of block 3, the first and second blocks 14-1 and 14-2 of the dial type selection are in the Urban dialing position, then dialed by pressing and releasing the dial key 2 all twelve digits of the long-distance subscriber. (Take

0 conditionally 8 the first digit of the set). They are convinced by the light digital indicators that the set is correct. Translation of the first and second blocks 14-i and 14-2 into the Interstate dialing position. It means,

5 that the contacts 14i have been switched so that it is possible in parallel code through block 10 to record 8 into block 6i, and contacts 142 have opened in the circuit between the fifteenth exit from block 3 and block b2.

0 Raises the tube from the lever, listens to the PBX. If the line is not occupied, it will press and release button 2. Even earlier, after dialing twelve digits, 1 stopped at the thirteenth exit from block 3. Then she could not descend, since this output has no connection with the circuit. But after pressing and releasing the button 2, 1 moved from the thirteenth exit to the fourteenth, got into block 6i,

0 than caused the issuance of 8 recorded there in the telephone network, and she went to the fifteenth exit. Here, again, the interruption of the communication, as contact 142 is open.

The subscriber again listens on the PBX. If a

5 line is free, it translates the first and second blocks 14-1 and 14-2 into the intracity dialing position (i.e., closes contact 142 in supply circuit 1 to block 62), which causes transition 1 to block b2, then

0 followed by the automatic issuance of all the remaining eleven dialing characters in the telephone network. After that, the scheme itself will come back to its original state for dialing a new number.

5 But it can happen that after issuing the first 8 (the first indicator cleared and the O number is highlighted on it), the PBX responded with intermittent beeps, then the subscriber (toggle switch 14 is in

0 position Long-distance dialing), by pressing and releasing the button in block 10, the parallel code enters 8 into block 6i, which is immediately fixed by the indicator of the first digit of the dial (all other digits of the dial

5 remained in their places).

The subscriber again listens on the PBX. If it is free, then pressing the button in blocks 9-1 and 9-2 until the indicator is completely cleared (it lasts 0, 8 s) and releasing it produces 8 into the network.

If there is no intermittent signal, it places the first and second blocks 14-i and 14-2 in the Long-distance dialing position, which causes the remaining eleven signals to be automatically output to the network.
