Abstract

Et velgersystem for bruk på en kundes bosted (2) innbefatter en hoved- kontakt (11) for tilkopling til nett-termineringsutstyr (f.eks. veggkontakt) (6) og for tilkopling til et antall slavekontakter (12) som hver kan være tilkoplet vanlige kommunikasjonsapparater slik som en telefon (7), faks- eller svare-maskiner (ikke vist). Ved mottakelse av et innkommende telefonanrop fra nettet, bruker hoved- kontakten signaler som identifiserer anropets kilde (innringerlinje-identitet (CLI))- signaler til å bestemme hvilken av slaveapparatene som skal anropes. Ved å bruke bare fire tråder (f.eks. det vanlige internlinje-arrangement) kan hovedkon- takten signalere individuelle slavekontakter (12) for å kople dem til eller fra linjen slik at et normalt hjemmetelefon-arrangement på enkel og økonomisk måte kan omformes til å innbefatte velgerfunksjoner. Forskjellige beskyttelsesmuligheter og alternative anropsmønstre i tilfelle av uteblitt svar, kan også være tilveiebrakt ved hjelp av hovedkontakten som innbefatter valgmuligheter for å tillate kommunika- sjon mellom to individuelle internapparater uten å benytte linjesystemet til hovedsentralen.
