Abstract

Et telekommunikasjonssystem har en bredbåndet, digital, lokal sløyfekrets i hver ende av en forbindelse og som er innrettet for å sende telefonisignaler ved å digitalisere dem og bære dem innenfor de digitale abonnentlinjesignaler for derved automatisk å svitsje telefonisignalet slik at det forbikobles de digitale abonnentlinjekretser i det tilfelle en av de digitale abonnentlinjekretser eller den tilhørende effektforsyning svikter.
