(1) Control when the PHS Remote Unit 2 Makes a Call In this case, when the control unit 27 inputs a call telephone number (step S 1), the control unit 27 inputs the call telephone number into the keypad 4 and the communication terminal 15. The source is determined by determining which one has been input (step S
2).

Here, if the control unit 27 determines that the caller telephone number has been input from the keypad 4, it determines that the caller is the self (PHS handset 2), and the wireless unit 28 performs the call processing in voice mode.

Here, when the control section 27 determines that the incoming telephone number is the telephone number of its own (PHS handset 2), it determines that the destination is its own, and executes the communication processing by the wireless section 28. (Step S24). As a result, the radio wave captured as the received radio wave by the antenna 9 is transmitted to the radio unit 2
The digital signal is converted into an analog signal by the D / A converter 31, converted into a received voice by the receiver 7, and output from the receiver 7 to the outside as the received voice.

On the other hand, when the control unit 27 determines that the incoming telephone number is the telephone number of the communication terminal 15, it determines that the destination is the communication terminal 15, and
Then, the type of the radio wave captured as the received radio wave is determined as data or voice (step S25).

When the controller 27 determines that the type of the radio wave captured as the received radio wave by the antenna 9 is data, the controller 32 converts the protocol of the data by the modem 32 (step S26), and the communication by the radio unit 28 is performed. The process is executed (Step S27). As a result, the data captured as a received radio wave by the antenna 9 is wirelessly processed by the radio unit 28, protocol-converted by the modem 32, and output from the communication unit 29 to the communication terminal 15.

The control unit 27 has a function for the communication terminal 15 to input and output voice. When the type of the radio wave captured by the antenna 9 as the received radio wave is determined to be voice, the control unit 27 The communication process is executed by the unit 28 (step S28). As a result, the sound captured by the antenna 9 as the received radio wave is wirelessly processed by the wireless unit 28 and output from the communication unit 29 to the communication terminal 15.
