Abstract (en)

[origin: US6577602B1] In a module for processing ATM cells of a cell flow on virtual channels of a virtual path that is configured for the insertion of OAM-specific cells with an OAM cell generator, a cell filter and processing unit are provided to which the arriving cell stream is supplied. A connection data memory is provided in communication with the cell filter and processing unit. A scan unit is in communication with the connection data memory and to which a controller is allocated. An intermediate buffer has an input connected to the output of the OAM cell generator. A multiplexer is provided to which the output of the cell filter and processing unit as well as the output of the intermediate buffer is supplied.
