摘要
FIELD: communications engineering; digital data transfer and synchronization systems; communication network synchronization systems.;SUBSTANCE: proposed method is characterized in that additional links are organized in network and provision is made for transferring sync signals in backup driving network component, output signals of the latter being generated bypassing internal generator from sync signals arriving from last first-priority component nn and from last second-priority component mm. Sync signal arriving from main sync signal supply is conveyed in series over network through backup driving network component bypassing internal generator; variation (reduction) in quality level of sync signals being used is entered in status message of STM-N heading. As a result, using backup path running to main driving component through m components does not cause closed-circuit synchronization. Hence, network will be always synchronized from one sync signal supply upon occurrence of any single accident.;EFFECT: enhanced quality of rendered communication services.;1 cl, 4 dwg
