The channel data is received by the slave 200, and at this time, the channel data is also intercepted by the slaves 300 and 400. Thereby, handset 200 switches the transmission / reception channel to the channel corresponding to the channel data in response to the received channel data, and
Handsets 300 and 400 switch their transmission / reception channels to channels corresponding to the channel data in response to the intercepted channel data.

The slave 200 sends a control signal indicating the completion of channel switching upon completion of channel switching.
To send to.

In response to the control signal indicating the completion of the channel switching, master unit 100 sends a control signal indicating a simultaneous call to slave unit 200. At this time, the control signal indicating that this is a general call is also intercepted by the slave units 300 and 400, and the slave units 300 and 400 turn on the sound receiving system by the intercepted signal, and are set in a state where only sound can be received. Become.

Here, the radio link required for the one-way voice call is completed. In this state, when a voice relating to the simultaneous call is input from the child device 200, the voice is transmitted via the parent device 100 to the child devices 300 and 40.
0, and when this voice is generated from the speakers 301 and 401 of the slave units 300 and 400, a one-way voice call is executed.

Next, the operation of this embodiment will be further described with reference to the flowchart shown in FIG. First, the child device 20
When an off-hook is made at 0 (step 501), it is checked whether an extension dial tone comes (step 502).
A wireless link is formed between the dial data and the next dial data, and it is checked whether the next dial data indicates a general call (step 5).
03) If the dial data does not indicate a simultaneous call, the process proceeds to other known extension processing (step 504), and this processing ends.

However, if it is determined in step 503 that the dial data indicates a general call,
The wireless link formed between the child device 200 and the parent device 100 is once disconnected (step 505), and thereafter, the wireless unit of the parent device 100 transmits a signal to each child device 200, 300, 400 (step 506). And each child device 200, 30
0 and 400 receive the data relating to this transmission (step 507).

Next, it is checked whether or not a wireless link has been formed with the slave unit 200 serving as the representative slave unit (step 508).
If a wireless link has been established with the handset 200, a simultaneous call state is set (step 510), and this process ends. However, if a wireless link is not formed with the slave unit 200 in step 508, the wireless link forming operation ends, and the wireless link is emptied (step 509).
This processing ends. According to such a configuration, master device 1
Just providing one wireless unit at 00 makes it possible to make a one-way voice call simultaneously.
