A device known as a telecontrol for detecting a faulty section of regeneration of digital information transmission lines, which makes it possible to find the place of damage in the transmission lines of digital information ll,

However, in this device for telecontrol, communication interruption is necessary for transmitting a test signal instead of a working signal.

The disadvantage of this device is the dependence of the detection time of the failed regeneration section on the presence of the initial signal in the information signal in the cycle

The purpose of the invention is to reduce the time of detection of a faulty regeneration area without interruption of communication.

This goal is achieved by the fact that in a telecontrol device for detecting a faulty regeneration section, comprising a transmitter of an information signal, the output of which is connected to the input of the transmitting hemisphere / 1ec of terminal line equipment consisting of indications. the control unit, the first output of which is connected to the control input of the receiver of the receipt signals, to the signal input of which, via the serially connected P signal regenerators of the receipt of linear nodes, telecontrol of the unattended regeneration sites and cable-line information pairs of the receipt of the receipt signal signal generator of the receiving semi-complement of the terminal linear equipment , the input, which through the P serially connected unattended regeneration sites and informational pairs of cables Line is connected to the output of the transmitting half set of terminal linear equipment, a linear code violation generator, a controlled linear code converter, a receipt signal transfer analyzer, the signal input of the linear code violation generator and the first input of the controlled converter are entered into the transmitting half line set of terminal linear equipment. linear code are combined and are the input of the transmitting half set of the terminal linear equipment, the installation input of the generator Violations of the linear code are connected to the second output of the control unit, the input of which is connected to the first output of the linear code generator, the second output of which is connected to the second input of the controlled linear code converter, the output of which is the output of the transmitting half-set of the terminal linear equipment, and to each output From C of the non-serviced regeneration sites, a different input is connected to each of the AND nodes of the linear telecontrol, while in the linear telecontrol nodes and into the receiving half of the terminal l the linear equipment includes a linear code violation detector and analyzer, as well as a linear code violation probability meter, and the linear code violation detector input and the first linear code violation analyzer first input are combined and are the input of the receiving semi-set of the terminal linear equipment and the input of each linear telecontrol node, the output of the linear code violation detector is connected to the second input of the linear code violation analyzer, the output of which is connected to the control input of the gene In this case, in the receiving semi-set of terminal line equipment, the output of the receipt signals is a linear code violation detector, the first and additional outputs of the Line Code Violation analyzer are connected to the corresponding inputs of the linear code violation probability meter, the receipt signals receipt terminals are connected to the analyzer inputs reductions of receipt signals, the other inputs of which are combined and connected to the second output of the generator for the destruction of a linear code, and the outputs of the analyzer The receipt signals are transmitted to the signal inputs. In addition, the linear code violation generator consists of serially connected dividers into two pseudo-random sequence generators, the output of the gated signal of which is the first, and the output of the period signal - the second output of the linear code violation generator, the input of which is the divider input into two, the installation inputs of the pseudo-random sequence generator and the divider into two are combined and are the installation input of the generator linear code violations. The linear violation violation analyzer consists of two consecutive splitters, a pseudo-random sequence generator and a modulo adder, the divider input being the first input of the linear code violation analyzer, and the second input is the second modulo adder input, the output of which is connected to a clock input of a pseudo-random sequence generator, the output of the period signal of which is the output of the linear code violation analyzer. The drawing shows a block diagram of the proposed device. A telecontrol device for detecting a faulty regeneration section, digital information transmission lines contains an information signal transmitter 1 transmitting a half-set 2 terminal line equipment, P line sets 3 a telecontrol, receiving half-set 4 terminal line equipment, a control block 5, a receipt signal receiver 6, a regenerator 7 signals receipts, serial to parallel converter 8, receipt signal transmission analyzer 9, indicator of faulty unattended regeneration station, linear code violation generator 11, controlled linear code converter 12, regeneration unattended sections 13, bipolar violation detector 14, linear code violation analyzer 15, receipt signal generator 16, bipolar violation probability indicator 17, divider 18 by two, the generator 19 is a pseudo-random sequence and the adder 20 modulo two. The device operates in two modes: in the scene mode, the reliability of information transmission by the linear path and the detection mode of the faulty regeneration section with simultaneous determination of the reliability of information transmission by each regeneration section. In the first mode, the linear code violation generator 11 is in the initial state due to incoming its setup input from the output of the signal control block 5 is reset. At the same time, the controlled linear code converter 12 generates a signal at the output of a linear code that is normal for the linear path, the bipolarity detector 14 isolates the linear code breaks that occurred only due to random noise in the linear path. Since the information structure of the signals input to the analyzer 15 of violations of the linear code does not match the structure embedded in the analyzer, the signal is not received at the input of the generator 16 of the receipt signals and no receipt is generated. , At the same time, no signal is received from the corresponding output of the analyzer 15 of violations of the linear code to the input of the meter 17, the probability of bipolar violation, and the device measures the reliability of information transmission along the path as a whole. In the second mode, the installation input of the generator 1.1 for violations of the linear code from the output of the control unit 5 is alternately received resolution signals, the duration of which is determined by the structure (cycle) of the pseudo-random sequence generator 19, which is part of the generator 11 of the linear code violations, and the reset signals, the duration which is determined by the transit time of the receipt signals from all unattended regeneration areas 13. During the action of the resolution signal, the linear code violation generator 11 generates at the input of the controlled linear code converter 12 an pulse sequence in accordance with its structure and the order of arrival of information symbols from the output of the information signal transmitter 1, due to which the standard linear code formation law violated in accordance with the structure of the signal at the output of the generator 11 of the violation of the {{code) line. With this, since the output of the controlled converter 12 of the linear code on the biolarity rush occurs symmetrically due to the action of the divider 18 on two positive and negative bipolarity violations alternate, loss of signal information or reduced reliability of the information signal due to violations of the linear code telecontrol is not happening. In the line sets 3 telecontrol and reception 4 half-boxes in the set 4 of the final bipolar equipment violations, the bipolar violations are detected by the detector 14 of bipolarity and are fed to the input of modulator 20 modulo 2, the second input of which receives the output of the generator 19 of a pseudo-random sequence identical to transmitting part. Thus, the signal at the output of the adder, 20 modulo two, is released in case of bipolarity disturbances caused by C6O51MI in regenerators, and does not occur in bipolarity disturbances caused by the operation of telecontrol. Since the modulo two adder output signal causes the pseudo-random sequence generator 15 to violate the code, a PSA-period signal does not arrive at the input of the generator 16 of the receipt signals and no receipt is generated. If, however, two signals are missing at the output of the adder 20 modulo 19, the pseudo-random sequence generator 19 of the linear code violations 15 completes its cycle and generates a period signal of the pseudo-random sequence at the input of the generator 16 of the receipt signals and the receipt is generated. The same signal, arriving at the corresponding input of the sensor 17 of the probability of bipolar violations, turns it off before the signal from the output of the adder 20 modulo two at the corresponding input, after which the meter 17 of the probability of violations of the bipolarity re-activates. The receipts signals of all linear P sets of telecontrol and receiving half set 4 of the terminal linear equipment are fed to the receiver 6 of the receipt signals sequentially directly to the regenerator 7 of the receipt signals, then converted by the register into parallel and from the outputs they are fed to the inputs of the analyzer 9 of the receipt signals reliability, which measures the output the number of received receipts to the number of cycles of the generator 11 linear code violations for each unattended regeneration point separate but. The results of the analysis are induced by the indicator 10 of the unserviceable maintenance-free regeneration point in the form of a frequency factor. The proposed device detects faulty and unstable regenerating areas and reliably measures the quality of regeneration areas that have reduced reliability without. interruption of communication. In this case, in the absence of test cycles, the service signal is not subject to additional interference.
