Abstract

Fremgangsmåte og innretning for telefon-telefaks-omkobling. Direkte i en bylinje er tilkoblet et forkoblingsapparat hvor det er anordnet en anropsregistreringsinnretning med koblingskomponenter, et koblingstrinn for en telefaks-anropsregistrering (CNG), en i bylinjen innsløyfet strømforsyning og en sloyfestrømregistreringsinnretning hvor til å begynne med telefaksapparatet kobles ut etter en definert tid, mens anropsvekselspenningen anvendes videre for koblingsrutinene, hvor den ved telefakstone-registreringen ved en aimen type forbindelse (for eksempel telefonsvarer) opprettholdes og etter en telefaks-registrering omkobles.Method and device for telephone-fax switching. Directly in a city line is connected a ballast where there is provided a call recording device with switching components, a switching step for a fax call registration (CNG), a power supply wired into the city line and a loop current recording device where initially a telephone connection is switched on, the call alternating voltage is further applied to the switching routines, where it is maintained at the fax tone registration for any other type of connection (e.g. answering machine) and switched after a fax registration.
