Abstract

Anordning for å opprette alternativ telekommunikasjonsvei mellom to teleabonnenter via en telesentral ved ufremkommelighet via vanlig fysisk telefonlinje. En avfølerkrets hos minst den ene abonnenten er innrettet til å avfølge telefonlinjen mellom sentralen og abonnenten for å detektere en eller flere av følgende parametre: spenningsfall på linjen uten samtidig linjestrøm; spenningsbortfall på linjen forårsaket av linjebrudd; manglende summetone på linjen: DTMF-toner på linjen; uidentifiserbare DTMF-toner på linjen; FSK-signaler på linjen; ASK-signaler på linjen; og pulssignaler på linjen. En velgerkrets er forbundet med avfølerkretsen for å koble abonnentens teleutstyr fra telefonlinjen til den alternative telekommunikasjonsveien ved tilstedeværelse av minst en av nevnte parametre. Den alternative telekommunikasjonsveien valgt fra gruppen bestående av: annen avfølbar, fysisk telefonlinje; teleforbindelse via strømforsyn- ingsnettet; radioforbindelse, f.eks. GSM, NMT, VHF, UHF; optisk kabelforbindelse; optisk, ikke-fysisk forbindelse; radiokommunikasjon via satelitt; ultralyd- kommunikasjonsforbindelse.
