Abstract
Metodo per la cellizzazione e la decellizzazione di un flusso di dati binari comprendente strutture informative note come unità tributarie o TU, ed in particolare TU 32, TU 21 e TU 12.A partire da un flusso informativo organizzato come una trama STM-1 (conforme quindi alle specifiche e alle norme internazionali), mediante una operazione di adattamento (Higher Order Path Adaptation), il flusso dei dati viene strutturato in una trama di ottetti di origine OF (Origin Frame), tipicamente all'interno di un modo di commutazione. Questa trama viene cellizzata e, dopo il trattamento delle informazioni, viene rioganizzata in una trama di ottetti di destinazione DF (Destination Frame) e da questa trama si riottiene una struttura STM-1 che viene avviata verso il successivo modo di commutazione senza ulteriori elaborazioni a livello di TU. (Figura 11)
