Module for OAM processing of ATM cells of a cell flux on virtual connections

A module for processing ATM cells of a cell flow on virtual channels and virtual paths that is configured for recognizing error conditions in the ATM inventory and for inserting OAM-specific cells for the generation of which an OAM generator (OZG) is provided. 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.
