Abstract

Den foreliggende oppfinnelse vedrører en synkroni-seringskrets inkludert en multiplekserings/demulti-plekseringsenhet (1) som mottar en bit-strøm svarende til en datapakke. Bit-posisjonene og verdiene innen en forhåndsbestemt del av en etterfølgende bit-sekvens av hver overførte datapakke blir kon-stant selektert, slik at en forhåndsbestemt kontroll-beregning vil gi en forhåndsbestemt verdi (f.eks. "0"). En etterfølgende bit-sekvens svarende til den forhåndsbestemte del av en etterfølgende bit-sekvens og tilhørende de respektive mottatte datapakker, blir vurdert for å fastslå i hvilken grad kontroll-beregningen gir den forhåndsbestemte verdi. Når det er oppnådd enighet, blir det antatt at avgrensningen mellom to svært nærliggende datapakker blir opprettet via bit-sekvensen til den forhåndsbestemte del av en etterfølgende bit-sekvens. Hver innkommende bit-strøm blir synkroni-sert via en styreblokk eller en styrelogikk (4, 9), ved å innføre en tidsforsinkelse svarende til syn-l kronisme i en serie-parallell omformer (3) for den 1 respektive bit-strøm. Den synkroniserte, parallell-:dannede bit-strøm (25) kan bli levert via styre-'blokken eller styrelogikken (4) til et minne (5) som leverer bit-strømmen til den utgående forbindelsen. (8) via bufferkretser (6) og en parallell-serieom-former (7).
