FIG. Figure 1 shows the structural electrical circuit of the register of an electronic and quasi-automatic automatic telephone exchange; in fig. 2 - the same as the battery pulse transmitter. I. . .

The proposed register (Fig. 1) contains a pulse correction unit 1, a 2 series switch, IZ elements, recorders 4, an electronic switch 5, a control block 6, a code converter 7 and a battery pulse transmitter 8 containing (Fig.) The first and second decoders 9 and 10,. counter 11, comparison blocks 12, element OR 13, element AND 14, inver-. torus 15 and generator 16,

The control of electronic and quasi-automatic telephone exchange works as follows. When information arrives in the form of battery pulses at the input of unit 1 from its output, the recovered information is fed to the first input of the first element I 3, the second input of which from the switch 2 receives a signal, unlocking the first element FROM, At the output of this element 3, a series of information pulses which was present at the input of the elements And 3, of the receipt to the corresponding registrar 4, the information pulse train is counted and stored in the binary code. After the end of the informative pulse train arriving at the input of switch 2, a signal is generated at its outputs, locking this element AND 3 and unlocking H: 1, the next element AND 3, after which the register is ready for further reception of information, the remaining elements AND remain locked. The process then repeats. After memorizing five digits of the register, the input from the first block 6 receives a request from the marker to transmit the first digit by multi-wire xdsm. At the same time, the control inputs of the electronic switch 5 from the output of block 6 are given in binary code the signal of switching signals from the output of the registrars 4 to the information inputs of the converter 7, to the control input of which from the block 6 a signal is issued that permits the converter 7 to operate the control input of transmitter 8 continues to receive a signal that prohibits its operation. When the converter 7 is operating, a signal in the multi-wire code is output from its outputs. When entering the second input of block 6 request

from the second digit transfer marker by battery pulses to the control inputs of the electronic switch 5 from the output of block b is supplied to. the binary code, the switching signal of the signals 5 from the output of the recorders 4 to the information inputs of the transmitter 8, the control input of which from the block b is given a signal permitting the operation of the transmitter 8, while the second control input of the transmitter 8 receives the setting signal driving it is ready to transfer information to its initial state, and a control signal is received to the control input of the transducer 5 l 7 that prohibits its operation; In the future, the process repeats, whichever,. in what form it is necessary to transfer information, either the re-sensor 8 or the converter 7 can work. After the last digit has been transmitted, a signal is sent to the third input of the block b, which translates it to its initial state, and from the block 6

25, a signal is supplied that switches the switch 2 to the initial state, the input of which is the first element. That And 3 the signal arrives, unlocking its switch 2, and on the second

j inputs of the remaining elements And 3 receives signals locking them. A control is sent to the register register entry, which sets it to its original, zero state. The control input of converter 7 is supplied

5 is a signal permitting its operation, and the control input of the transmitter 8 from block 6 receives a signal prohibiting its operation,

Q Transmitter 8 operates as follows.

When a signal arrives at the control input enabling the transmitter 8 to work, the information inputs of the first decoder 9 in binary code receive a digit to be transmitted. This digit is decrypted by the first decoder 9, as a result of which one of the outputs. ) a high potential can be set, which goes to the first input of one of the blocks 12. To the second input of one of the blocks 12 comes from one of the outputs of the second decoder 5, the decrypted state (Counter 11, which was transferred In the initial (zero) state by the control signal at the control input.When the zero state of the counter 11 is decrypted, a high potential is set at the low-order output of the second decoder 10, the digit value to be decoded to the information input of the first one.

5, the decoder 9, and the decrypted state of the counter 11 are compared by blocks 12.

If the state of the first and second decoders 9 and 10 does not match, then a high potential appears at the output of the comparator unit 12, which through the element OR 13 and the open element AND 14 (the element AND 14 opens, because the first decoder 9 decrypts the value digits that cannot be zero, and therefore, the low potential of the first decoder 9 has a low potential at its output, which, inverter 15 passes through, is inverted and a high potential is fed to the input of the element 14, which is applied to the generator input 16, excites him. and a pulse which enters the input of the counter 11 and is transferred to the next state is output from it. In this case, the pulse enters the output of the transmitter 8. The process repeats until the state of the second decoder 10 becomes the same as the state of the first decoder 9, after which

At the output of all the blocks 12, low potentials are set and the generator 16, having no excitation, stops generating pulses. When transferring the next digit process

repeated again. After transmitting the last digit, the first decoder 9 receives a signal prohibiting its operation from the control input, while the output of the first discharge decoder 9 sets a HIGH potential, which is inverted by inverter 15 and locks the AND element (to prevent the generator 16 from malfunctioning) counter 11 it does not receive an installation signal at the control input.

“The use of the proposed invention allows for the transmission of information both by battery pulses and by a multi-wire code, and also reduces the likelihood of information transmission failures, which increases the reliability of the electronic and quasi-electronic PBX register.
