Abstract
Doråpner-samtaleanlegg, som muliggjør toveis samtale via en totråds forbindelse og mellom etter hverandre passerende døråpner-samtalesteder og et derfra valgt telefonapparat til en abonnent. For løsning av opptredende problemer ved forskjellige spenninger og strømmer, er anordnet en kaskadekoblbar forbindelsesmodul 40 med en omkobler 50, som ved reaksjon på et fra døråpner-samtalestedet 30 kommende velgertegn tilkobler kun dette døråpner-samtalestedet til totråds TK-anlegget l O og forbinder det andre henholdsvis de andre døråpner-samtalestedene med en strømkilde 60, som mater inn en hvilestrøm.
