The recording control unit 3 (Fig. 2), depending on the set operating mode, is designed to form commands that control the operation of the connecting unit 2, the tariff 4, and the code register 5. In addition, the recording control unit

3produces the conversion of binary-decimal code information in binary code

and issuing this information in a certain time sequence to the caller 4.

Register code 5 (Fig. 3) is intended

for dividing the information and address part of the program in the division node 10 into two parts and temporary storage of these parts of information.

Register 11 of the information part is intended for temporary storage of information about the time interval of the tariff zone when the device is in recording mode.

The address part register 12 is intended for temporary storage of the code of the called city, in the recording mode and in the information retrieval mode from the memory block 14. The device operates in two modes: the mode of recording information about the subscriber’s talk time interval determined by the tariff number into the device’s memory. zones multiple to the value of one coin; the mode of operation or the mode of reading the information of its destruction according to the dialed city code. The write or read mode is set manually by the work mode switch located in the write control block 3. In the write mode, the dialer of the call station 1 dials the seven-digit program code, the first digit being the exit code to the long-distance telephone station, the next three digits are code cities and in turn the address of the cell in which the information will be entered, the last three digits are the information part of the seven-digit program code and represent the times call interval determined by the number of the tariff zone.

In the recording mode, the recording control unit 3 at the first output generates a signal that, when arriving at the second input

0, the connecting unit 2 blocks and disconnects the connecting unit 2 from the subscriber line, in order to exclude the passage of the seven-digit program code to the long-distance telephone exchange. In addition, at the second output of the recording control block 3, a signal is generated allowing the three characters of the information part of the seven-digit program code to pass from the first output of the connecting block 2 through the code 5 register to the input

0 of the recording control block 3, as well as the passage of three characters of the address part from the first output of the connecting block 2 through the register 5 to the first input of the caller 4.

After dividing the seven-digit code 5 of the program into two parts and storing the address and information part in the code 5 register, the first input of the tariff 4 from the first output of the code 5 register enters the parallel binary city code, which is in turn the block cell address. memory 14 of the caller 4. Information from the third output of the recording control unit 3, converted into a parallel binary code, is received via information and command buses to the second input of the caller 4 and then to the memory cell 14, the number of which is determined by the address part of the dialed seven-digit program code. Via the same channel, from the third output of the recording control block 3 to the second input of the caller 4, a command is received to record in the memory 14 of the caller 4 information about the time interval of the conversation defined by the number of the tariff zone. After the information is entered into the first cell of the memory 14 of the tariffiser 4, the information is entered into the next cell by re-dialing the seven-digit program number for another city and t; to the full filling of the memory cells of the memory 14. The size of the memory 14 is limited to the maximum number of the city code. For the Soviet Union, for example, such a code corresponds to the number 999. After filling the information of the memory block 14 of the caller 4, the operation mode switch 7 in the recording control block 3 is set to the Work position and the device is ready to call subscribers in any of 999 cities, codes which are stored in the device memory. In the mode “Subscriber operation by removing the handset from the callout call site 1 and listening to the readiness buzzer in the telephone, the dialer dials the digit of the output to the long-distance telephone exchange, the three-digit city code and the telephone number of the called subscriber. The dialed combination is fed to the connecting unit 2, to the second input of which, from the first output of the recording control unit 3, a command is issued permitting the translation of the dialing pulses to the subscriber line. The connecting unit 2, in addition to transmitting the dialing pulses to the line, generates the dialing pulses transmitted to the code 5 register. The code 5 register operates in the second input mode and receives a command from the second output of the recording control block 3 to prohibit the selection of three characters of the information part from the pulses set formed by the connecting unit 2. The partition node. The 10 register of code 5 from the dialed code sequence and the number of the called subscriber selects the city code, fixes it in the register of address part 12, then from the first exit of the code 5 register, the city code on the address bus goes to the first input of the caller 4. In the “Operation memory block” mode 14, the caller 4 is transferred to the read mode by a command of the third output of the write control unit 3, i.e. the information retrieval mode. When an address bus arrives at the first input of the calibrator 4 of a binary city code in the converter of the code 13 of the calibrator 4, this code is converted into a decimal code, which is the address for the selection of the desired cell for memory 4. A selection is made from the memory block 14 of information, namely the code of the time interval of the conversation, determined by the number of the tariff zone, which is a multiple of the value of one coin. Information from the output of memory 14 is recorded in the information storage register 15. The information storage register 15 as well as the counter (clock pulses) 18 is reset by a command received on the command board from the second output of the connecting block 2 to the third input of the tariff 4, when removed from the lever of the handset of the call station 1. The fourth input of the caller 4 receives sync pulses from the synchronizer 6, which are fed to the counting input of the counter 18, with a repetition period of 1 s. By removing the handset on the opposite side of the subscriber line, the subscriber presses the button “Conversation” located in the call center 1, in this case, a command is formed at the second output of the connecting block 2, which, when received via the command bus, goes to the third input of the caller 4, and therefore , and at the input of the resolution of the counter 18, it starts up. Counter 18, the output of which is connected to one of the inputs of the comparison circuit, counts the number of pulses of the synchronizer 6 until the numbers in the comparison block 17 are compared to its inputs from the output of the storage register 15 and the counters 18. As soon as the comparison occurs numbers, block 17 will form a command that, after passing through the element OR 16, will reset the counter 18, as well as a signal that, when the tariff 4 goes to the third input of the connecting block 2, allows the latter to form a coma In this case, connecting block 2 analyzes the presence of a coin of desired value, which pays for the next time interval of the conversation, and if it is not present, connecting block 2 disconnects the call-calling node 1 from the subscriber line.
