摘要
FIELD: information technology.;SUBSTANCE: invention proposes not block transmission of synchronisation signals of unacceptable quality from a higher hierarchy level synchronisation network to a lower level communication network, i.e. limit the value the level of quality of synchronisation signal streams coming into STM-N at connection points, and also assign fixed quality levels to signals allowed for synchronisation.;EFFECT: warning on serious violations in the operation of a communication network and raising the quality of provided services by raising the quality of network synchronisation.;2 dwg
