The present networks communicating terminal is communicated with computer and communicating terminal after on the microcomputer special-purpose driver and application program being installed, run application and just can dial or receive IP phone, and it provides PC to PC and two kinds of operating functions of PC to Phone.During as the callee, when the monitoring incoming call, produce bell signal to receiver by master controller, eject the bell prompt window on the computer desktop simultaneously, behind the connecting incoming call, ring stops to enter talking state.Voice output to master controller by transmitter via coder/decoder coding, are transferred to computer by the usb interface circuit again and pass on network and arrive the other side at last.The other side's voice signal is sent to this side's computer by network and is sent to master controller via USB cable, and master controller is sent to coder/decoder again, outputs to receiver at last; During as the calling party, by keyboard input the other side number, the computer expert crosses calling network to sending out.The concrete path of voice is identical with as the callee time.
The purpose of this utility model also can reach by taking following measure:
Keyboard is provided with 1～9 key, * key, 0 key, # key, ON/OFF key, acknowledgement key, redial key, delete key, indicator light is lighted when master controller connects microcomputer and operate as normal, when being used to come bell, the receiver that is positioned at the shell middle and upper part receives when ring and conversation, the transmitter that is positioned at the shell bottom side send words when being used to converse, the connector of terminal bottom can be connected with the USB port of microcomputer by stube cable.
Special-purpose Control Software is installed on the external computer, is integrated with the USB driver module in the master controller, and cable couples together external computer and master controller; Behind the running control software, dial the other side's number by keypad, can be behind connection the other side by transmitter and receiver and the other side's conversation, be sent to master controller after the voice signal that transmitter is sent is encoded by the voice coder/decoder and deliver to computer by master controller by the USB oral instructions again, arrive the other side by network; On the contrary, the other side's voice signal, is passed on by master controller and to be exported by receiver behind voice coder/decoder decode to master controller by Network Transmission.
Described special-purpose Control Software can be finished following work:
1) connect microcomputer and terminal, IP phone be dialed and be received to running control software just can by keyboard or computor-keyboard, and it provides PC to PC and two kinds of operating functions of PC to Phone; Online with USB interface of computer, the function (PnP) of plug and play is provided, needn't sound card and additional power source;
During 2) as the callee, the microcomputer monitoring network is to incoming call is arranged, the notice master controller, produce the bell signal of built-in natural frequency and power by master controller, to receiver, ejection comes the bell prompt window on the computer desktop simultaneously by coder/decoder output the tinkle of bells, keypad " affirmation " button or " reception " button of clicking in the desktop window get final product connecting incoming call, computer desktop ejects the conversation window, can be talked about and send the adjusting of speech amount, and ring simultaneously stops to enter talking state;
3) voice output to master controller by transmitter via the coder/decoder coding, being transferred to computer by usb circuit again passes on network and arrives the other side at last, the other side's voice signal is sent to this side's computer by network and is sent to master controller via USB cable, master controller is sent to coder/decoder again, outputs to receiver at last; During as the calling party, import the other side's number process by path by keyboard, master controller scans the keyboard input, then be transferred to the computer expert and cross calling network to sending out, if the other side selects not answer, then this side's computer desktop ejects prompt window and stops call automatically, if select to answer to sending out, then eject the conversation window, can be talked about and send the adjusting of speech amount, conversation is set up.
Described master controller mainly is formed by connecting by computer chip U1 and peripheral crystal oscillator thereof, and the model of computer chip U1 is tiger560.
The voice coder/decoder is made of integrated speech chip U2, and the model of integrated speech chip U2 is Mc14lc5480.
Outstanding effect of the present utility model is:
