METHOD FOR CONTROLLING EQUIPMENT OF TELECODE COMMUNICATION SYSTEMS Russian patent published in 2018 - IPC H04B17/00 H04L1/24 

FIELD: test technology.

SUBSTANCE: test sequence is fed to the input of equipment and the output sequence of the terminal node of the equipment is compared with a reference sequence. If said two sequences match, the equipment is considered operable. In case of a mismatch between said two sequences, the output sequence of the average a posteriori probability of failures of the intermediate node of the equipment is compared with its reference sequence. If said two sequences match, the equipment nodes before the average a posteriori probability of failures by the intermediate node are considered to be operable and diagnosis of the nodes following the average a posteriori probability of failures by the intermediate node is performed. In the case of a mismatch between said two sequences, the output sequence of the average a posteriori probability of failures of the intermediate equipment node, located before the previous average a posterior probability of failures by an intermediate node of the equipment, is compared with its reference sequence and so on until a faulty average based on average a posteriori probability of failure of the intermediate node is found. When choosing the average a posteriori probability of failures of the intermediate node, internal feedback of the equipment coming from the equipment nodes located behind the selected intermediate node is switched off during the comparison process.

EFFECT: higher accuracy and reliability of diagnosing nodes of telecode communication equipment.
