Is transmitted to base unit 100.

At step S21, the control unit 250 of the base unit 100 controls the transmission / reception unit 140 to transmit the ACK signal to the handset unit A.

In step S22, the control unit 250 of the master unit 100 controls the transmission / reception unit 140 to transmit the inter-slave unit calling signal to the slave units A and B.

At step S23, the control unit 59 of the child device A is operated.
If it is determined that 0 has received the inter-slave unit calling signal, it controls the transmission / reception unit 510 to cause the parent device 100 to transmit an ACK signal.

The ACK signal is similarly transmitted from the child device B to the parent device 100.

In step S24, the control unit 250 of the master unit 100 sends the above-mentioned A from the two slave units from the transmission / reception unit 140.
When the signal indicating that the CK signal has been received is detected, the transmission / reception unit 140 is controlled to transmit the ringing tone ringing instruction signal. When the control units 590 of the slave units A and B determine that the ringing tone ringing instruction signal has been received, the speaker 540 outputs an extension ringing tone, and the process proceeds to step S25.

At step S25, the controller 59 of the child device B is operated.
When 0 determines that the extension key has been pressed from the input unit 560, the transmission / reception unit 510 is controlled to transmit the extension call request signal to the master device 100.

In step S26, the control unit 250 of the parent device 100 controls the transmission / reception unit 140 to send an ACK.
The signal is transmitted to the handset B.

At step S27, the control unit 250 of the parent device 100 operates. By controlling the transmitting / receiving unit 510, an extension call request signal is transmitted to the handset A.

In step S28, the control unit 59 of the child device A is
0 controls the transmission / reception unit 510 to transmit an ACK signal to the master device 100.

In step S29, the controller 59 of the child device A is
When detecting a signal indicating that the extension key is pressed from the input unit 110, the control unit 0 controls the transmission / reception unit 510 to transmit the transmission request signal to the master device 100.

Subsequently, in step S30, the parent device 100
Controls the transmission / reception unit 140 to transmit the reception request signal to the child device B, and in step S31, the control unit 590 of the child device B controls the transmission / reception unit 510 so that A
The CK signal is transmitted to base unit 100.

After that, the handset A becomes the transmitting side and the handset B becomes the receiving side, and a call is made between the handset A and the handset B by the half-duplex communication method.

When the slave B is on the transmitting side and the slave A is on the receiving side, the transmission request signal is transmitted from the slave A to the master 100.

As described above, in the apparatus of this embodiment,
When registering the child device 500 in the parent device 100, data indicating that the parent device 100 can perform inter-child device communication by the full-duplex communication method or the half-duplex communication method from the parent device 100 to the child device 500. Since the data is transmitted, the child device side can determine which communication method the parent device can use to communicate between the child devices.

Therefore, the handset device 500 can carry out a handset-to-handset communication in accordance with the handset-to-handset communication method of the base unit 100, and when the handset device is added, the user makes a mistake and the handset device It is possible to solve the problem that a handset for exclusive use of the half-duplex communication system or the full-twentieth communication system is purchased and the inter-handset communication cannot be performed.

In this embodiment, the inter-slave communication mode data is transmitted from the master 100 to the slaves, and in the subsequent inter-slave communication, the slaves communicate with each other based on the inter-slave communication method data. Although the configuration is such that the call between the slave units is performed by the method, when the slave unit is registered, the master unit 100 transmits the master unit ID and the slave unit call data to the slave unit, and the slave unit side transmits the ID and the slave unit call data. Is stored, the ID data transmitted from the master unit is compared with the stored ID data at the time of a request from the slave unit to start communication between the slave units, and if they match, the subsequent communication is stored with the above ID. The configuration may be such that the inter-slave communication is performed based on the thus-successed inter-slave communication data.

Further, in the present embodiment, when a slave unit registration operation is performed on the slave unit 500 side and subsequently a slave unit registration operation is performed on the master unit 100 side, the slave unit 500 transfers from the master unit 100 to the slave unit 500. Although the configuration is such that the data of the call system is transmitted, the master unit 100 transfers to the slave unit 500 by simply performing some operation on the master unit 100 side or the slave unit 500 side. It is also possible to adopt a configuration in which data of the call system is transmitted.
