Abstract

En svitsj (25) for en tjenestenotde (tjeneste-knutepunkt) (18) som utgjør en del av en telekommunikasjonsnett, har en svitsjematrise (32) og en rekke linjegrensesnitt-kretser (37). Hver av linjegrensesnitt-kretsene (37) innbefatter en krysspunkt-bryter (47), flere av en første type prosesserings-anondning (52) (slik som digitale signalprosessorer), og en andre type prosesserings-anordning slik som en mikroprosessor (38). De digitale signalprosessorene er koplet til krysspunkt-svitsjen (47) ved hjelp av et seriegrensesnitt (56) som er egnet for å motta digitaliserte tallsignaler. Mikroprosessoren er koplet til krysspunkt-svitsjen via en parallell-buss (57), og krysspunkt-svitsjen innbefatter anordninger for å forenkle kommunikasjon mellom den digitale signalprosessoren og krysspunkt-svitsjen.
