Method for the cellization and decellization of a binary data flow including informative structures known as tributary units or TUs, and in particular TU-32, TU-21 and TU-12. Starting from an informative flow set up like an STM-1 frame (corresponding so to the international specifications and norms), through an adaptation operation (Higher Order Path Adaptation), the data flow is structured in an origin byte frame OF (Origin Frame), typically inside a switching node. This frame is cellizised and, after the processing of the information, it is reorganized in a destination byte frame DF (Destination Frame), and from this frame a STM-1 structure is obtained again, which will be transmitted to the following switching node without further elaboration at TU level. |
