With a cordless telephone that has a slave station connected to the wired communication switching network via the master station, and the slave station uses a battery as a power source, the slave station sends a hold signal to the master station when performing a hold operation. When the master station stops the transmission / reception function with the master station and receives the hold signal, the master station sends a hold tone signal to the wired telecommunication switching network and enters the reception stand-by state. When the is received, the hold status is released.

Moreover, since the master station receiving the hold signal continues to send the hold tone signal to the wired telecommunication switching network, it is possible to send the same hold tone signal to the wired telecommunication switching network as in the conventional case. Also, after the slave station sends a hold signal to the master station, the transmission / reception function of the slave station stops and the master station goes into a reception standby state. Unnecessary occupation of the limited wireless line is prevented and effective use of the wireless line can be achieved.

受けてから受信待機状態になるようにしてもよい。As shown in FIG. 1, in the master station 1, the control unit 11, the transmission / reception unit 12, and the holding sound circuit unit 13 are connected to the subscriber line 1 via the line connection unit 14. The control unit 11 receives a paging signal transmitted through the subscriber line 1 and closes the subscriber line 1 when the slave station 2 goes off-hook. A storage unit that stores the identification code set between the two, a carrier sense unit that determines whether or not a radio wave including the identification code is received, and whether the received identification code matches the identification code stored in the storage unit It is provided with a determination unit for determining whether or not, a channel control unit for determining which of a plurality of wireless lines provided in advance is to be used. The transmitter / receiver 12 transmits and receives radio waves to and from the slave station 2 through the antenna 16.
The ringing signal transmitted through the subscriber line 1 is transmitted to the slave station 2 by radio waves, and when the slave station 2 is in an off-hook state, an off-hook signal is sent to the control unit 11 to close the subscriber line 1, After the closing of l, the voice signal transmitted through the subscriber line 1 is transmitted / received to / from the slave station 2. In addition, child station 2
Goes into the on-hook state, an on-hook signal is sent to the control unit 11 to open the subscriber line 1. The master station 1 is provided with a power supply unit 15 for obtaining a DC power supply from a commercial power supply to the internal circuit. The output end of the power supply unit 15 is also connected to a charging terminal T 1 that supplies power to an external circuit. On the other hand, the slave station 2 includes a transmitter / receiver 22 that transmits and receives radio waves to and from the master station 1 via the antenna 26, and the transmitter / receiver 22 is connected to the controller 21 similar to the master station 1. The control unit 21 stores a storage unit that stores an identification code, a carrier sense unit that determines whether a radio wave including the identification code has been received, and whether the received identification code matches the identification code stored in the storage unit. A determination unit or the like for determination is provided. An operation unit 24 including a switch group is connected to the control unit 21.
When the dial signal is sent out by operating the button, the master station 1 closes the subscriber line 1 and then sends the dial signal to the subscriber line 1 by the radio wave transmitted through the transmitting / receiving unit 22. Since the transmitter / receiver 22 is connected to the handset 27, the voice signal transmitted / received to / from the master station 1 by radio waves can be transmitted to the subscriber line 1. The operation state of the operation unit 24 is displayed on the display unit 28. The power source of the slave station 2 is a secondary battery 25 such as a Ni-Cd battery, and the DC power source supplied through the charging terminal T 2 which is detachably connected to the charging terminal T 1 of the parent station 1 is used as a charging circuit unit 29 Through secondary battery 25
Supply to. Next, the operation during holding will be described. 2A shows the operation of the slave station 2, and FIG. 2B shows the operation of the master station 1.
To enter the hold state, first, the hold operation is performed by the operation unit 24 of the slave station 2. When the holding operation is performed, the master station 1 is changed from the slave station 2 to the master station 1.
A hold signal is sent to the display section 28, and at the same time, a hold display is displayed on the display unit 28. When the master station 1 receives the hold signal from the slave station 2, the master station 1 activates the hold sound circuit section 13 to send the hold sound signal to the subscriber line l, and then disconnects the wireless line to receive the signal. It will be in a standby state. Also, when the parent station 1 disconnects the wireless line, the child station 2
Also enters the reception standby state. When the hold state is released by the operation unit 24 of the slave station 2, the slave station 2 sends a line connection signal to the master station 1, and when the master station 1 receives the line connection signal, the hold sound circuit unit 13 is stopped. Release the hold status and return to the call status. As described above, at the time of holding, it is possible to prevent the wireless signal from being transmitted from the slave station 2 to the master station 1 while transmitting the hold signal to the subscriber line l.
It is possible to prevent exhaustion of the secondary battery 25 that becomes the power source of the power supply and occupancy of the pending wireless line. In the above-described embodiment, the display unit is suspended in the slave station 2.
Although the hold display at 28 is displayed, as shown in FIG.
The holding sound circuit unit 23 may be provided so that the handset 27 outputs the holding sound during the holding. After transmitting the hold signal from the slave station 2 to the master station 1, the master station 1 transmits an answerback in order to confirm that the master station 1 has received the hold signal. Then, after receiving the answer back, the reception standby state may be set.

である。As described above, according to the present invention, the slave station stops the transmission / reception function with the master station after sending the hold signal to the master station when the hold operation is performed, and the master station receives the hold signal and the wired communication switching network. In addition to sending the hold sound signal to the slave station, the slave station is set to be in the reception standby state until the hold state is released.When the hold operation is performed in the slave station, after transmitting the hold signal to the master station, Since the transmission / reception function of the slave station is stopped, the battery of the slave station is not exhausted during the hold, and the master station that receives the hold signal continues to output the hold tone signal to the wired communication switching network. The wired communication switching network has an advantage that it is possible to send the hold tone signal as in the conventional case. Also, after the slave station sends a hold signal to the master station, the transmission / reception function of the slave station is stopped and the master station is in a reception standby state, so the wireless line is opened during the hold,
Thus, it is possible to prevent unnecessary occupation of a wireless line having a limited number of lines and to effectively use the wireless line.
