Abstract: The device comprises a protocol processing circuit (CTP) connected to a network (TTA), a memory (M) having a transmission memory and a reception memory, a transmission control memory (FE) and a reception control memory (FR). The memories are connected to the processing circuit via a data bus (BD) and to a processor for processing the level 2.2 via a bus (BP). The control memories are of the FIFO type, the transmission control memory (FE) being written by the processor and read by the processing circuit, and the reception control memory (FR) being written by the processing circuit and read by the processor. The processing circuit (CTP) transmits and receives cells containing signalling information, and ensures the level 2.1 functions of the protocol: detection of transmission errors cell by cell, detection of losses or additions of cells, fragmentation into cells of a message delivered by the processor and deinterlacing of the cells relating to several messages on reception.
