Abstract:
Telecommunication node for an Asynchronous Transfer Mode (A.T.M.) telecommunication network including:means (400) for performing Segmentation and Reassembly (SAR) of ATM cells, said SAR means particularly providing Virtual Channel Identifier (VCI) and Virtual Path Identifier (VPI) translation and comprising a Direct Memory Access (DMA) mechanism for a storage external to said SAR means, said SAR means performing a first DMA access when said VCI/VPI identifiers are representative of an Error Code Correcting (ECC) procedure to be carried out in said node, and said SAR means performing a second DMA access at a second address when said VCI/VPI correspond to an ATM message that does not require a local ECC procedure; a Reed-Solomon Coder and Decoder (200) for performing an ECC procedure on ATM cells, control means (100, 190, 300) for controlling said Reed-Solomon Coder and Decoder for performing an error correcting procedure in response to the detection of said first DMA access.
