The priority setting block 30, the fourth input, the signal output, the readout output and control, whose outputs are connected respectively to the output of the register occupancy detection unit, to the second input of the buffer accumulator, to the readout input - the unit of equally accessible registers of channel memory and causes of failures and corresponding the control inputs of the input key block, combined with the corresponding control inputs of the output key block, whose output is connected to the second input of the output register, the output and the third input to They are expensively connected respectively to the input of the code converter and to the output of the gauge element, the input of which is connected to the signal input of the input key block, to the second input of the additional key and to the second output of the buffer accumulator.

The drawing shows a structural electrical circuit of the device for displaying the state of the communication channels.

The proposed device contains a block of input amplifiers 1, an intermediate register 2 connected to a sensor 3 of control signals, a comparison block 4, a priority setting block 5 and a buffer store b, as well as an additional register 7, block 8 of input keys, block 9 of equally accessible registers channel numbers and causes of failures, the signal outputs of which are connected to the inputs of the indicators 10 (10-1) + (10-b, register occupancy determination unit 11, output key block 12, time register 13, additional key 14, delay element 15, output re ISTR kodopreobrazovatel 16 and 17.

The proposed device operates as follows.

Information about the faulty communication channels and the reasons for their failure through the input amplifier unit 1 enters an intermediate register 2, from which the code combination of pulses goes to comparison unit 4, which compares the received information (on the state of the communication channel) with the additional register 7. If the received information coincides with the information recorded on this channel in the additional register 7, then the comparison unit 4 generates a reset signal to the intermediate register 2, thereby preparing it for the reception following her one combination. Otherwise, Comparison Unit 4 generates an ignal for overwriting information in the drive drive. B. At the same time: this triggers the sensor 3 of the control signals, and the information enters the priority setting block 5, having determined the priority of the incoming information by the type of code combination and source, places the received message in the queue of the buffer accumulator 6 using the first control signal from the sensor 3. On the second control signal, from the sensor 3, the priority setting unit 5 opens one of the keys of the 8 input keys block and one of the keys of the 12 output keys block, preparing them to skip the input and output signals, respectively formations.

By the third control signal from sensor 3, the installation unit 5 permits the rewriting of the message b at the beginning of the queue in the buffer accumulator through one of the keys of the 8 input keys block into the corresponding registers of block 9 of equally accessible memory registers of channel numbers and causes of failures, while The indicators (10-1) - (10-b) show the number of the communication channel and the cause of the accident. At the same time, the content of this information is recorded, and additional register b, delay element 15 is started, additional key 14 is opened, allowing the time (hours, minutes, seconds) of the message to be entered in output register 16 to be recorded.

By the fourth control to the signal from sensor 3, the priority setting block 5 allows the output of equal-accessible memory registers of the channel numbers and causes of information failures to arrive at block 9 through the prepared one of the keys of the block 12 output keys to the output register 16, after which the delay element 15 is triggered from the output of which a pulse arrives at the third input of the output register 16, permitting the release of information and the time of its arrival through the code converter 17 to the registration device.

When all the registers of block 9 of equally accessible memory registers of numbers and causes of failures are filled, a busy signal is sent through the block for determining the occupation of registers 11 to the block for setting the priority 5. In this case, in the case of receipt of information about the liquidation of a communication channel accident, a signal about this from the comparison unit 4 enters the priority setting unit 5, thereby blocking the busy signal, after which the device operates as described above.
