Abstract

PURPOSE:To prevent a battery of a slave station from being consumed during holding by sending a hold signal to a master station and stopping the transmission reception function of the slave station when holding is applied to the slave station. CONSTITUTION:When the holding operation is applied, a slave station 2 sends a hold signal to a master station 1 and a display section 28 applies hold display. When the hold signal from the slave station 2 is received by the master station 1, the master station 1 operates a hold tone circuit section 13 to send a hold tone signal to a subscriber line l and interrupts a radio line to be in the reception standby state. Moreover, when the master station 1 interrupts the radio line, the slave station 2 reaches also the reception standby state. When an operation section 24 of the slave station 2 release the hold state, the slave station 2 sends the line connection signal to the master station 1, the master station 1 stops the hold tone circuit section 13 to release the hold state thereby restoring the state to the speech state. Thus, the consumption of a secondary battery 25 being the power supply of the slave station 2 and the occupancy of the radio line during the holding are prevented.

クを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, a control section 11, a transmitter/receiver section 12, and a hold music circuit section 13 are connected to a subscriber line l via a line connection section 14. The control unit 11 includes a normal telephone function unit that receives a calling signal transmitted through the subscriber line l, and closes the subscriber line l when the slave station 2 goes off-hook, as well as a paired slave station. 2, a carrier sense unit that determines whether radio waves containing the identification code have been received, and whether the received identification code matches the identification code stored in the storage unit. and a channel control section that determines which of a plurality of pre-provided wireless lines to use. The transmitting/receiving unit 12 transmits and receives radio waves to and from the slave station 2 via the antenna 16, and transmits the calling signal transmitted through the subscriber line l to the slave station 2 using radio waves, so that the slave station 2 is in an off-hook state. When this occurs, an off-hook signal is sent to the control unit 11 to close the subscriber line 1, and after the subscriber line 1 is closed, the voice signal transmitted through the subscriber line 1 is transmitted and received with the slave station 2. It is. Further, when the slave station 2 enters the on-hook state, it sends an on-hook signal to the control unit 11 to release the subscriber line l. The master station 1 is provided with a power supply unit 15 that obtains DC power from a commercial power supply to internal circuits. The output terminal of the source section 15 is also connected to a charging terminal T, which supplies power to an external circuit. On the other hand, the slave station 2 includes a transmitting/receiving section 22 that transmits and receives radio waves to and from the master station 1 via an antenna 26, and a control section 21 similar to that of the master station 1 is connected to the transmitting/receiving section 22. The control unit 21 includes a storage unit that stores an identification code, a carrier sense unit that determines whether a radio wave including an identification code has been received, and a carrier sense unit that determines whether the received identification code matches the identification code stored in the storage unit. It is equipped with a determination unit that makes a determination. An operating section 24 consisting of a group of switches is connected to the control section 21. When the operating section 24 is operated to set the off-hook state and a dial signal is sent, the radio waves sent out via the transmitting/receiving section 22 are used to connect to the master station. 1, after the subscriber line l is closed, a dial signal is sent to the subscriber line l. Since the transmitting/receiving section 22 is connected to the handset 27, the voice signals transmitted and received by radio waves to and from the master station 1 can be transmitted to the subscriber line l. The operating state of the operating section 24 is displayed on the display section 28. The power source of the slave station 2 is a secondary battery 25 such as a Ni-Cd battery, and the DC power supplied through the charging terminal T2, which is detachably connected to the charging terminal T of the master station 1, is passed through the charging circuit section 29. It is supplied to the secondary battery 25. Next, the operation during hold will be explained. Figure 2 <8> is slave station 2
FIG. 2(b) shows the operation of the master station 1. To put the terminal on hold, first perform a hold operation using the operation unit 24 of the slave station 2. If you perform a hold operation, slave station 2 will switch to master station 1.
A hold signal is sent to the user, and at the same time a hold signal is displayed on the display section 28. When the hold signal from the slave station 2 is received by the master station 1, the master station 1 activates the hold tone circuit section 13 to send the hold tone signal to the subscriber line l, and then disconnects the wireless line and receives the hold tone signal. Goes into standby mode. Furthermore, when the master station 1 disconnects the wireless line, the slave station 2 also enters a reception standby state. When the hold state is canceled 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, it stops the hold tone circuit unit 13. to cancel the hold state and return to the talking state. As described above, when on hold, it is possible to transmit a hold signal to the subscriber line l while preventing the wireless signal from being transmitted from the slave station 2 to the master station 1. It is possible to prevent the secondary battery 25 that serves as a power source from being consumed and from occupying the wireless line while the device is on hold. In the embodiment described above, the display unit 2 is displayed while the mobile station 2 is on hold.
8 is displayed on hold, but as shown in Figure 3,
A hold tone circuit unit 23 may be provided so that the hold tone is output from the handset 27 while the handset is on hold.Also, after the slave station 2 sends the hold signal to the master station 1, In order to confirm that the hold signal has been received, the master station 1 may send an answerback, and the slave station 2 may enter the reception standby state after receiving the answerback.

When a hold operation is performed on a slave station, the transmitting and receiving functions of the slave station are stopped after transmitting a hold signal to the master station, so the batteries of the slave station are not consumed while on hold, and the hold signal is transmitted to the master station. Since the master station that receives the call continues to send the music-on-hold signal to the wired communication switching network, the wired communication switching network has the advantage of being able to send out the same music-on-hold signal as in the past. In addition, after the slave station sends a hold signal to the master station, the transmitting and receiving functions of the slave station stop and the master station enters a reception standby state, so the wireless line is released while it is on hold, and the number of lines decreases. This has the effect of preventing wasteful occupancy of the limited wireless line and making effective use of the wireless line.
