METHOD AND CIRCUIT ARRANGEMENT FOR DISTURBANCE-FREE REDIRECTION OF A MESSAGE CELL STREAM ONTO AN ALTERNATE ROUTE

摘要

Within a cell-oriented communication network (ATMN), a message cell stream supplied to a switching equipment (CCa) located at the start of a path pair is duplicated by the switching equipment in response to a request. The two message cell streams resulting therefrom are supplied to a central synchronization device (AS) allocated to the switching equipment (CCb) located at the end of the path pair, being supplied thereto separately via an active path (AP) and via an alternate path (EP) allocated thereto. In the synchronization means, a synchronization of the two message cell streams ensues, while the message cell stream of the active path is being initially forwarded. After this, only the message cell stream of the alternate path is forwarded, upon disconnection of the central synchronization means from the transmission path.
