SU801277A1 - Device for monitoring discrete information channel - Google Patents

Description

The invention relates to telecommunication technology and is intended to assess the quality of the transmission of discrete information, in particular digital _ linear paths (CLT). ^uh

A device for control channel transmission of digital information comprising a series connected matching block, error isolation and shaper ¹¹ vre- variables slots, and series-connected control unit and the display unit [1]. ''

However, the known device has a low accuracy control. fifteen

The purpose of the invention is to increase the accuracy of control.

This goal is achieved by the fact that in the device for monitoring the transmission channel of discrete information, 20 comprising a sequentially connected matching unit, an error allocation unit and a time shaper, and a series-connected control unit and an indication unit 25, an error amount analyzer, a permission unit and a prohibition unit are introduced the first, second and third inputs of the analyzer of the number of errors are connected, respectively, - 30 with the input ^ and also the first and second outputs of the shaper of time intervals, t the first output of which is connected to the first inputs of the permission block, the inhibit block and the control unit, the second input and output of which are connected, respectively, to the output and the second input of the inhibit block, the third input of which is connected to the first output of the error number analyzer, the second and third outputs of which are connected , respectively, with the second input of the permission unit and with the combined third inputs of the control unit and the permission unit, the output of which is connected to the fourth input of the control unit.

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

A device for monitoring a channel for transmitting discrete information includes a matching unit 1, an error allocation unit 2, an error number analyzer 3, a permission unit 4, a control unit 5, a shaper 6 time intervals, a prohibition unit 7, and an indication unit 8.

The device operates as follows.

At the input of the coordination unit 1, which serves to coordinate the output of the CLT with the control device, discrete information from the linear path is received. From block 1, the information is fed to the input of block 2 error allocation, in which the allocation of error pulses of the signaling. From the output of the block 2 error allocation, the signal enters the shaper 6 time intervals, which is included for the time required to read the analyzed error-free interval. At the same time, the information arrives at the analyzer 3 of the number of errors, the second and third inputs of which receive the resolution delayed from the output of the shaper delayed by time t

6. The analyzer 3 is necessary to enable the control unit 5 and to analyze the number of errors received, which, in turn, allows or prohibits the further passage of information. Permission for the passage of information goes to block 4 permission, the output of which the signal goes to block 5 control. The information prohibition signal is received by analyzer 3 to the prohibition unit 7, the output of which also goes to the control unit 5, the output of which confirms the prohibition for information passing. The second output of the control unit 5 serves to control the display unit 8.

The display unit 8 is used for light alarm Alarm in case the probability of the measured error is greater than the specified RD

Norm if P _MGM .oyL ^p · n th measurement Continued if P _d <Ρ _ΗΐΜοω όΡ _Η · Thus, the proposed 'device allows, while maintaining the same session control, like in the known device, to provide a more accurate assessment of the quality of the digital linear tract. The Neumann-Pearson criterion is replaced by the Bayes criterion, which consists in maximizing the ratio of the probabilities of correct and erroneous decisions. This criterion allows you to control not only the state of the Norm and the Accident, but also the Continuation of the measurement. By introducing a new criterion, the time for monitoring the emergency state of the CLT is reduced by approximately 50%.
