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.Device for establishing alternative telecommunication path between two telecommunications subscribers via a telecommunications switching center by impossibility via a regular physical telephone line. A sensing circuit of at least one subscriber is arranged to sense the telephone line between the exchange and the subscriber to detect one or more of the following parameters: voltage drop on the line without simultaneous line current; line failure due to line breakage; missing dial tone on the line: DTMF tones on the line; unidentifiable DTMF toner on the line; FSK signals on the line; ASK signals on the line; and heart rate signals. A dialing circuit is connected to the sensor circuit to connect the subscriber's telecommunications equipment from the telephone line to the alternative telecommunication path in the presence of at least one of said parameters. The alternative telecommunication path selected from the group consisting of: another tactile, physical telephone line; telephone connection via the power supply network; radio connection, e.g. GSM, NMT, VHF, UHF; optical cable connection; optical, non-physical connection; satellite radio communications; ultrasound communication connection.
