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.A telecommunication system has a broadband digital local loop circuit at each end of a connection which is adapted to transmit telephony signals by digitizing them and carrying them within the digital subscriber line signals, thereby automatically switching the telephony signal into the digital subscriber line circuits in it. in case one of the digital subscriber line circuits or the associated power supply fails.
