Description

A kind of radio telephone

Technical field

The utility model relates to a kind of radio communication product, particularly relates to a kind of radio telephone with extension set resonance.

Background technology

At present, the wireless telephony communication of main flow all is card one machine or an one-telephone multi-card, makes this communication product be confined to a place and maybe must carry just and can carry out communication, can not be implemented under the situation of a card, many wireless telephony communications are dialed simultaneously or are answered, thereby save its cost.The utility model will be realized the function of a card multimachine, and the possibility of realization will be provided for this reason.

Summary of the invention

In order to reach above-mentioned functional objective, the utility model provides a kind of radio telephone with extension set resonance, makes under the situation of a main frame, realizes that a plurality of extension sets all have an external speech communication passage.

Technical solutions of the utility model are, a kind of radio telephone, comprise wireless telecommunications and control module, keyboard, display screen, voice control unit, handle, antenna and SIM card is characterized in that wireless telecommunications and control module connect at least one Subscriber Line Interface Circuit by the I/O expanded circuit, and Subscriber Line Interface Circuit connects the I/O expanded circuit again by dtmf decoder.Subscriber Line Interface Circuit is provided with the extension set interface, and subscriber line interface can directly drive the common PSTN phone that is connected the extension set interface.

The utility model beneficial effect is: main frame adopts the user interface circuit of technical grade wireless communication module and specialty, on hardware, wireless network communication and user interface circuit (SLIC) organic combination are in the same place, by software control wireless speech mechanics of communication and wireless speech are connect that art is molten to be one, thereby realize a card multimachine function.

Description of drawings:

Fig. 1 is a theory diagram of the present utility model.

Below in conjunction with embodiment the utility model is further specified.

Embodiment:

As Fig. 1, a kind of radio telephone, comprise wireless telecommunications and control module 1, keyboard 2, display screen 3, voice control unit 4, handle 5, antenna 6 and SIM card 7, wireless telecommunications and control module 1 connect at least one Subscriber Line Interface Circuit 10 by I/O expanded circuit 9, and Subscriber Line Interface Circuit 10 connects I/O expanded circuit 9 again by dtmf decoder 8.Subscriber Line Interface Circuit 10 is provided with extension set interface 11.

The utility model is when realizing that the electric work energy is removed in dialing, be connected the extension set of extension set interface 11, if off-hook, then user interface circuit Unit 10 just can detect, and this signal sent to wireless telecommunications and control module Unit 1, wireless telecommunications and control module Unit 1 respond and control user interface circuit Unit 10 in the mode of interrupting and switch to off hook state, if extension set dialing this moment, then its formed dtmf signal is decoded by the dtmf decoder unit 8 behind user interface circuit Unit 10, the signal that the dtmf decoder unit 8 is finished decoding is fed to wireless telecommunications and control module Unit 1, wireless telecommunications and control module Unit 1 respond and go to read by I/O expanded circuit Unit 9 code value of dtmf decoder unit 8 decoding in the mode of interrupting, and be presented on the display screen 3, repeat this process, dialing was to wireless network after wireless telecommunications and control module Unit 1 received all numbers, this time go electric dialing thereby form, wireless telecommunications simultaneously and control module 1 unit controls voice control unit 4 gating voice channels are in case the other side connects then can set up speech communication.

If the main frame dialing is gone, can pass through keyboard 2 buttons, wireless telecommunications and control module Unit 1 receive the button number, and with this number dialing to wireless network, this time go electric dialing thereby form, wireless telecommunications simultaneously and control module 1 unit controls voice control unit 4 gating voice channels are in case the other side connects then can set up speech communication.

The utility model when wireless telecommunications and control module Unit 1 have detected incoming call, then removes the gating voice channel by control voice control unit 4 when realizing the incoming call pickup feature, and sends the tinkle of bells and make the main frame starting of oscillation; Make by control line circuit unit to be co-located in Ring Mode, make the extension set starting of oscillation thereby produce ring; Thereby reach the purpose of main extension resonance.In when main frame shows to come, wireless telecommunications and control module Unit 1 are encoded into DTMF standard incoming call with caller ID by the protocol requirement of caller identification, by control voice control unit 4 it is sent to the extension set that is connected extension set interface 11 through user interface circuit Unit 10, thereby make extension set show caller ID.But this moment the main frame extension set all off-hook receive calls, also can receive calls simultaneously.When main extension received calls simultaneously, main extension those who answer can both hear caller's sound, and the caller also can hear the those who answer's of main extension sound.But can not communication between the main extension.

Wireless telecommunications and control module 1 are meant the wireless communication networks and the control module of the upgrading that networks such as comprising GSM, CDMA and 3G/LTE thereof or mobile communication carrier can provide.

Power unit circuit 12 provides power supply, and it is hands-free 13 that voice control unit 4 also provides, and wireless telecommunications and control module 1 also are connected with data port 14.

Adopt the radio telephone of band extension set resonance of the present utility model, can be implemented under the situation of a card, many wireless telephony communications are dialed simultaneously or are answered, thereby save its cost.

Claims

1, a kind of radio telephone, comprise wireless telecommunications and control module, keyboard, display screen, the voice control unit, handle, antenna and SIM card, it is characterized in that wireless telecommunications and control module connect at least one Subscriber Line Interface Circuit by the I/O expanded circuit, Subscriber Line Interface Circuit connects the I/O expanded circuit again by dtmf decoder.
