The drawing shows a structural electrical circuit of the proposed device.

The device contains n subscriber sets (AK) 1, transmitter 2 and receiver 3, which make up the data transmission equipment (ADC) 4, n blocks 5 for phasing and converting codes each of which contains switch 6, first converter 7 of code, first decoder 8 phasing combinations, first prohibition element 9, first counter 10, write pulse shaper 11, second code converter 12, second decoder phasing combination 13, second prohibition element 14, second counter 15, read pulse shaper 16, delay element 17, two shaper 18 and 19 shear pulses, as well as elements 20 and 21 coincidence.

The device works as follows.

In the initial state, the switch 6 is in the Off position.

which provides a readiness pulse (s) for the ADF 4, writing a unit to the first bit of the converter via stage I of switch 6 and shifting the somatic converter 7 through delay element 17, stage II of switch 6 and the driver 18 at each input to the unit 5 of readiness pulse from the ADF 4 When receiving a p. (Readiness pulses, the decoder 8 allocates n units and issues a prohibition against prohibition element 9. It is time to issue impulses of readiness from the ASC 4 to the imaging unit 1.9 of the 5 pulses output of the combinations (willows) and cause shift Since the bits of the converter 12 are received by one bit. Since the ADF 4 assigned to the AK1K bus is missing, when the m output pulses are received, the decoder 13 selects a combination of all zeros, the total number n and prohibits the prohibition element 14. In the initial state of block 5 described, prohibition elements 9 and 14 do not work and do not issue AK 1 a readiness pulse (IGx) and an information output (IO) pulse n, until switch 6 is in the Off position. .

When translating switch 6, the position of the Work is carried out, first of all, the phasing mode of the transducer 1.2 of the receiving station, and then the conversion of the HI combination code. .

When phasing, the pulse is ready, the ADF through stages 1 and II of switch 6 in the position of Work (lower) and shaper 18 enters the shear bus of converter 7 and provides output from the output (n + +1) of the unit The transmitter's bus 2 of the ADF 4. At the first shift at the output of the decoder 8, the signal disappears and, therefore, the prohibition of the prohibition element 9 is lifted, which, when it receives the next readiness pulse, ensures its passage to counter 10 with a cycle of readiness. 10 a driver 11 for signa conversion by starts kotorrmu combinations code during transmission. Upon receipt of the readiness pulses from the ADF 4 p + 1 to the k-th bus of the ADC 4 transmitter, a combination of phasing consisting of n + 1 units is realized. At the receiving station, the bits of this combination are output from the k-th bus of the receiver 3 of the ADF 4 to one of the blocks 5, where they are written to the first j of the converter 12 and the shift of the output pulses. When the transducer receives 12 bits from the tire, the decoder 13 selects a phasing combination and removes the prohibition from the prohibition element 14 (allowing passage of output pulses to the counter 15), i.e. ensures the installation of the transducer I2 of the receiving station in the same position, i as the transducer 7 of the transmitting station. After performing this operation, the code conversion process begins.

When transmitting, this transformation is started from the moment when the counter 10 of the PM cycle is released according to the readiness pulses received from the ADF 4. The signal selected by the counter 10 is fed to the imaging unit 11 and 25 seconds later as the readiness pulse of the 5 JC unit is received in parallel. code from AK1 of his p - bit combination, which is recorded through elements 20. of coincidence in converter 7. When the ADF 4 receives a readiness pulse, it enters through element 9 prohibiting counter 10, as well as from the second stage of switch 6 through shaper 18 by 35 transducer shift bus 7. When shifting the contents of transducer 7 by one bit, the K-th transmitter bus of ACC 4 (bus 1a) is output. bit combination AK 1. After 40 p, the readiness pulses to the transmitter 2 input of the ADF 4 transmit (all bits of the recorded combination. At the time of issuing the last bit of the combination, the counter 10 generates a readiness pulse 45 (IG) of block 5, which is AK1 and provides rewriting his next combination via elements 20 of the match to the converter 7.50

When receiving bits of the transmitted p - bit combination AK1 at the opposite station, receiver 3 of the ADF 4 outputs an output pulse and n is the discharge of the specified combination by 55 converter 12. At the same time, the pulse of the geode first shifts the contents of the converter 12 by one bit,

and for the first bit of this, transforming the bodies records the value of the bits of the AK1 combination accepted from the ADF 4. In addition, the incoming output pulse also passes through the prohibition element 14 to the counter 15 and is recorded. When the counter counts 15 output pulses, the n-bit of the combination transmitted from AK1 is completely recorded in the converter 12. At the same time, the output pulse of the output driver 1 is generated by the received driver's combination. With this pulse, the contents of the converter 12 are rewritten through a match element 21 to the input of the terminal device-. interacting AKi.

After performing these operations, the receiving converter 12 is set to the zero state and begins the next cycle of receiving the n-digits of the transmitted combinations from the AK1, opposite station.

Thus, the execution of the considered block 5 of two serially connected (information transfer-reception bus of the ADF) converters 12 and connecting them using the specified method to the ADC of the device provides simultaneous phasing (determining the beginning of the combination when receiving) and converting the codes of the information combinations
