Abstract

Den foreliggende oppfinnelse vedrører en ATM-system- adaptert tre-trinns svitsjeenhet (1) omfattende en flerhet av innkommende grupperelaterte ledere (2), idet hver gruppe er forbundet med et første svitsje- trinn (3) tildannet som en inngangskrets, en flerhet av utgående grupperelaterte ledere (4) idet hver gruppe er forbundet med et andre svitsjetrinn (5) tildannet som en ut-krets, samt et tredje svitsje- trinn (6). En styreenhet (10) samvirker med nevnte svitsjetrinn for å kunne forbinde en av de innkom- mende ledere (2a') med en selektert utgående leder (4a') ved hjelp av en koplingsbane som er utpekt ved hjelp av nevnte mellomrelaterte tredje svitsjetrinn (6). Hver av de utgående ledere som tilhører det første svitsjetrinn (3), samvirker med en elektro- optisk omformer. Respektive forbindelser (3a'') mellom det første svitsjetrinn (3) og det tredje svitsjetrinn (6) omfatter en optisk leder. Det tred- je svitsjetrinn (6) er innrettet til å overføre optiske informasjonsbærende signaler gjennom nevnte koplingsbane. Koplingene (Ga11) mellom det tredje svitsjetrinn (6a) og det andre svitsjetrinn (5) omfatter optiske ledere og innkommende ledere som tilhører nevnte andre svitsjetrinn, er forkoplet ved hjelp av en optoélektrisk omformer.
