タ通信の切替えは同様の手順に従って行う。When the wireless telephone 3 goes off-hook and makes a call, the control device 11 of the wireless device 6 controls the selector 16 to connect the voice codec 8 and transmits a “SETUP” signal to the exchange 5. The “SETUP” signal includes the communication type “voice + data”. In the exchange 5, when the control device 14 receives the “SETUP” signal from the wireless device 6, after receiving the “CALL PROC” signal to the wireless device 6, the control device 14 transmits “SETUP” to the wired telephone 1 based on the dial number included in the “SETUP” signal. "Send the signal. After that, the “ALERT” signal and “CON”
When the N "signal is received, those signals are transmitted to the radio 6 and the wired telephone 1 is transmitted via the voice codec 7.
The path control of the switch 13 is performed so that the wireless telephone 3 is connected to the wireless telephone 3, and the voice communication between the wired telephone 1 and the wireless telephone 3 is started. Then, when you want to switch to data communication, the voice → data switching instruction speech data switch 15, the control unit 11, "INFO (FA: MODE
N ON) "signal to the exchange 5. In the exchange 5, the radio 6 sends an" INFO (FA: MODEN ON) "signal.
Upon receiving the signal, the control device 14 sets the voice codec 7
Is released, the path control of the switch 13 is performed so as to connect the wired data terminal 2 and the wireless device 6 via the data communication device 9, and an “INFO (FI)” signal is transmitted to the wireless device 6. The control device 11 of the wireless device 6 sends “IN”
When the FO (FI) "signal is received, the data communication device 10
To control the selector 16 to start the data communication between the wired data terminal 2 and the wireless data terminal 4.
In addition, if you want to switch to voice communications, Ri by the data → voice switching instruction of voice and data switching unit 15, the control device 11, "INFO (FA: MODEN OFF )"
The signal is transmitted to the exchange 5. When the exchange 5 receives the “INFO (FA: MODEN OFF)” signal from the wireless device 6, the control device 14 releases the data communication device 9 and connects the wired telephone 1 to the wireless device 6 via the voice codec 7. Then, the path control of the switch 13 is performed so as to transmit an “INFO (FI)” signal to the wireless device 6. Radio 6
The control device 11 from the exchange 6 sends “INFO (FI)”
When the signal is received, the selector 16 is controlled to connect the voice codec 8, and the wired telephone 1 and the wireless telephone 3 are connected.
To start voice communication with. Thereafter, switching between voice communication and data communication is performed according to the same procedure.
