When a call is received from the other subscriber in the standby state, the wireless fixing device 200 detects a ring signal input through the telephone line and informs the central processing unit 254 of the ring signal.

At this time, the central processing unit 254 that recognizes the input of the ring signal controls the data sending unit 251 to send the ring data RING DATA.

Accordingly, the ring data is mixed with the high frequency signal generated by the oscillator 222 by the phase control circuit 253, amplified by the transmit RF amplifier 223, and then propagated to the air through the transmit filter 224 and the antenna.

In this case, the wireless mobile device 300 receives the ring data transmitted from the wireless fixing device 200 and is input to the receiving RF amplifier 332 through the receiving filter 331. MIXER 333 mixes the high frequency signal generated by the oscillator 334 by the phase control circuit 353 and the received RF signal amplified above, and demodulates the mixed signal 335 by high frequency. The signal is separated and restored to the original ring data.

Accordingly, when the data shaping unit 352 formats the ring data and delivers the ring data to the central processing unit 354, the central processing unit 354 controls the ring signal generator 314 to connect the ring signal to the terminal device connection terminal 311. The ringing tone is generated in the terminal device by transmitting to the terminal device.

Subsequently, when a ringing tone is generated in the terminal device connected to the terminal device connection terminal 311 of the wireless mobile device 300, the LOOP detection circuit 313 recognizes the operation by receiving the handset of the terminal device. The central processing unit 354 transmits the call data through the data transmitting unit 351.

At this time, when the call data is mixed with the high frequency signal generated by the oscillator 322 by the phase control circuit 353, the transmit RF amplifier 323 amplifies the mixed signal and the call data is transmitted through the transmit filter 324 and the antenna. Spreads in the air

Accordingly, when the wireless data device 200 receives the call data transmitted from the wireless mobile device 300 and is received by the receiving RF amplifier 232 through the receiving filter 231, the wireless fixing device 200 receives the receiving data from the receiving RF amplifier 232. Amplifying the received RF signal, the mixer 233 mixes the high frequency signal generated by the oscillator 234 by the phase control circuit 253 and the received RF signal amplified above, and demodulates the mixed signal. ) Separates the high frequency signal and restores the original call data.

When the communication path between the wireless fixing device 200 and the wireless mobile device 300 is connected by the process of (1) and the terminal device is in a call state, the voice / data signal input to the terminal device is the wireless mobile device 300. In the voice signal amplifier 321 of the control unit, the size of the voice / data signal is adjusted and the adjusted signal is mixed with the high frequency signal generated by the oscillator 322 and amplified by the transmitting RF amplifier 323 and then the transmission filter ( 324 and propagates into the air through the antenna.

In this case, when the voice / data signal transmitted from the wireless mobile device 300 is received by the antenna, the wireless fixing device 200 passes only the frequency band to be received by the reception filter 231 and amplifies the high frequency in the reception RF amplifier 232. After this, the mixer 233 and the demodulator 235 restore the original voice / data signal.

Therefore, when the LPF circuit (low filtration circuit) 236 filters the high frequency components mixed with the restored voice / data signal, the voice signal amplifier 237 amplifies the voice / data signal and then the TEL-LINE circuit 211. The voice / data signal is transmitted to the other subscriber by transmitting to the telephone line through the telephone line.

3. The process of receiving the voice / data signal from the subscriber of the opposite party when the wireless communication path is connected through the process of (1) will be described.

When the voice / data signal of the other subscriber is input to the TEL-LINE circuit 211 of the wireless fixed device 200 through the telephone line, the voice / data signal is amplified by the voice signal amplifier 221 and then by the oscillator 222. The high frequency signal is mixed and transmitted to the transmitting RF amplifier 223. The transmitting RF amplifier 223 amplifies the high frequency signal and propagates to the air through the transmission filter 224 and the antenna.

In this case, when the voice / data signal transmitted from the wireless fixing device 200 is received by the antenna, the wireless mobile device 300 passes only the frequency band that the reception filter 331 intends to receive and amplifies the high frequency in the reception RF amplifier 332. After that, the high frequency signal is separated through the mixer 333 and the demodulator 335 to restore the original voice / data signal.

Accordingly, the restored voice / data signal is removed from the high frequency component in the LPF circuit 336, amplified by the voice signal amplifier 337, and then transferred to the terminal device through the terminal connection terminal 311. Play data.

4. When the terminal device receives a call from the other party subscriber will be described in the call connection process.

The call 351 is controlled and the call data is mixed with the high frequency signal generated by the oscillator 322 and amplified by the transmit RF amplifier 323 and then propagated to the air through the transmit filter 324 and the antenna.

In this case, when the radio data from the wireless mobile device 300 receives the call data transmitted from the antenna, the receiving RF amplifier 232 amplifies the received RF signal and the amplified received RF signal and the mixer 233 The high frequency signal is separated through the demodulator 235 to restore the original call data, and the restored call data is formatted by the data shaping unit 252 and transmitted to the central processing unit 254.

Accordingly, the central processing unit 254 controls the data transmitter 251 to transmit the confirmation data regarding the call data to the wireless mobile device 300, and also controls the relay controller 240 to drive the relay 241. Since the wireless fixing device 200 and the wireless mobile device 300 are connected to each other and the wireless fixing device 200 is connected to the telephone line, the terminal device is in an off-hook state.

Accordingly, the voice / data signal is transmitted and received between the terminal apparatus and the other subscriber in the same process as in (2) and (3).

5. A process of disconnecting a terminal device from a counterpart subscriber will be described.

When the handset of the terminal device is put down, the wireless mobile device 300 transmits the LOOP sensing circuit 313 to the central processing unit 354 and transmits the off data to the central processing unit 354. The control unit 351 controls the off data to be mixed with the high frequency signal generated by the oscillator 322 and amplified by the transmit RF amplifier 323 and then propagated to the air through the transmit filter 324 and the antenna.

In this case, when the radio data transmitted from the wireless mobile device 300 is received by the antenna, the wireless fixing device 200 amplifies the received RF signal by the receiving RF amplifier 232 and the amplified received RF signal is mixed with the mixer 233. The high frequency signal is separated through the demodulator 235 to restore the original off data, and the restored off data is shaped by the data shaping unit 252 and transmitted to the central processing unit 254.

Accordingly, the central processing unit 254 controls the data sending unit 251 to send the confirmation data for the off data, and also controls the relay control unit 240 to turn off the driving of the relay 241 to fix the radio. As the connection between the device 200 and the wireless mobile device 300 is disconnected and the wireless fixing device 200 disconnects the connection with the telephone line, the terminal device becomes on-hook.

6. The operation when calling the subscriber from the terminal device will be described.

The wireless mobile device 300 transmits the loop detection circuit 313 to the central processing unit 354 when the handset is heard by the terminal device. Then, when the counterpart subscriber number is input, the DTMF recognition circuit 312 recognizes this and the central processing unit. Forwarded to 354.

At this time, when the central processing unit 354 controls the data transmitter 351 to transmit dial data corresponding to the counterpart subscriber number, the dial data is mixed with the high frequency signal generated by the oscillator 322 to transmit the RF amplifier 323. After high frequency amplification in the radio wave propagates through the transmission filter 324 and the antenna.

Accordingly, when the wireless fixing device 200 receives the high frequency signal carrying the dial data from the antenna, the high frequency signal is amplified by the receiving RF amplifier 232 and the mixer 233 separates the mixed high frequency signal, and then the demodulator 235 receives the high frequency signal. The original dial data will be restored.

Accordingly, when the data shaping unit 252 forms the original dial data and transmits the original dial data to the central processing unit 254, the central processing unit 254 transmits a signal corresponding to the dial data to the DTMF sending circuit 213 and the DTMF. The transmitting circuit 213 sends the corresponding DTMF signal to the telephone line and calls the subscriber.
