Abstract
A fixed-line telephone adaptor comprises a first adaptor circuit, a second adaptor circuit, a switch unit and an RJ11 (registered jack 11) connector. When the first adaptor circuit is connected with the RJ11 connector by the switch unit, a digital/analog converter converts an RJ11 signal into a first carrier signal, and the first carrier signal is coupled to an alternating voltage signal by a first coupler for transmission through an alternating current line. When the second adaptor circuit is selected to be connected with the RJ11 connector, a second coupler separates the alternating voltage signal coupled with a second carrier signal from the second carrier signal, and an analog/digital converter converts the second carrier signal into the RJ11 signal which is then output to the RJ11 connector. Signal transmission among fixed-line telephones can be realized by the fixed-line telephone adaptor and the alternating current power line, the fixed-line telephone adaptor is quick and convenient, and the line is simplified.
