Abstract

The invention discloses a telephone dialer with USB interface. The computer sends out the dial command by the USB interface for controlling the dialing from the outside line, then the user talks by using the telephone of external connection which is parallel to the outside line. The key point of the technical proposal is that the invention comprises an independent shell 7, a USB interface 1, a central processor unit 2, an off hook unit 3, a dial unit 4, a polarity transition unit 5 and a plug of outside line 6. The plug of outside line 6 is connected with the polarity transition unit 5, the polarity transition unit 5 is connected with the off hook unit 3, the pick-up unit 3 is connected with the dialing unit 4, and the central processor unit 2 is connected with the USB interface 1, the off hook unit 3 and the dialing unit 4. By operating the computer software, the user controls the invention to dial, thereby prompting the dial efficiency.

Description

Technical field [0001] The invention relates to a telephone dialer, especially a telephone dialer with a USB interface. Background technique [0002] At present, the known telephone set is connected to the telephone outside line and used separately, and the dialing of the telephone set is completed by manually operating the telephone set keyboard.
