Abstract
Et tast telefon system'Innebefatter flere porter (19) son er sammenknyttet av portassoslerte to-vels kommunikasjonskanaler (11) som blir svi tenet synkront av overførings bit tilstander mellom kanalene' for a tilveiebringe kommunlkaajonsbaner mellom portene på en måte soa er styrt av en sentral prosessor (7). Portene kan også sammenknyttes til og via den sentrale prosessoren ved hjelp av portassoslerte meldlngskanaler (60). En grensesnlttkrets (8) reagerer på den sentrale prosessoren og meldlngskanalslgnalene for å regulere «trommen av meldinger som mottas av den sentrale prosessoren, og for å effektuere enkle og flere kanalfordelInger av meldinger fra den sentrale prosessoren. Meldlngskanalene tillater telefonldrlft og fungerer slik at den er tllvelebragt enten Innenfor den sentrale prosessor, eller ved hjelp av passende apparatlnnretnlnger som er forbundet med en hvilken som helst av portene.
