  • Corded/cordless telephone
    Patent number: 4752949
    Abstract: A telephone capable of operation in a cordless or corded mode. The telephone is basically operative in the cordless mode through the provision of electronic transmitting and receiving elements individual to the base unit and the portable handset. The base unit and the handset are provided with conversion switching circuits coupled to be responsive to the connection of a multi-conductor cord between the base unit and the handset to convert the telephone to corded operation. The conversion circuits disable the transmitting and receiving circuits in both the base and handset and permit the telephone signals to be conductively transmitted between the units through the conductors of the cord.
