Special telephone for set-top box

Abstract

The invention discloses a special telephone for a set-top box. The special telephone comprises a common telephone, a voice conversion module, a cable and a standard interface, wherein the voice conversion module is used for converting audio and control signals into two-line public switched telephone network (PSTN) signals; the cable is directly connected with the voice conversion module; and the standard interface is formed at the other end of a cable body and is used for being connected with the set-top box. According to the embodiment of the invention, the special telephone is manufactured by adding the voice conversion module on the common telephone and is provided with one cable, so the cables and the interfaces between the set-top box and the telephone are reduced, the cost is reduced, and the communication quality and the using convenience are improved at the same time.
