Method and unit for the recomposition in a single flow of two or more redundant cell flows outputted from redundant switching fabrics (ASF-a, ASF-b) of an ATM telecommunication system. The method includes the steps of labelling each cell being inputted into the switching fabrics (ASF-a, ASF-b) with a time label (TS) and of storing the cells of the output of the switching fabrics (ASF-a, ASF-b) in a cell buffer (CB). The cells are extracted from said cell buffer when a time span is elapsed, starting from the moment of input of said cell into said fabric, which is equal to a maximum suitable amount of time (MD). The recomposition unit comprises said cell buffer (CB) with optimized capacity as a function of the maximum number of cells which can really be present at the same time in the unit itself. |
