[Industrial application field]

The present invention relates to a parent-child telephone.

0002

[Conventional technology]

With conventional parent-child phones, when a call arrives, the recipient answers the call using the parent phone, and then The configuration was such that the transfer to the machine could be switched manually.

0003

[Problem that the idea aims to solve]

With the conventional parent-child telephones mentioned above, when a call arrives, the recipient answers the call using the parent device, and then The system is configured so that the recipient manually switches the transfer to the handset, so the caller can It is not possible to connect the telephone line directly to a specific handset, and once The problem is that the connection to the target handset is not possible until someone on the calling side answers. There is a point.

[Means to solve the problem]

The parent-child phone of this invention consists of one base unit that connects to a telephone line, and an extension to this base unit. In a parent-child phone that is equipped with a plurality of handsets that are connected via a receiving section that identifies and receives a push button signal from the telephone line after the , and determining the type of the push button signal identified and received by the receiving unit, and Sends out a ring tone to the handset that is previously associated with the type of push button signal. It has connection control means for automatically connecting to the telephone line after a response.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0006] FIG. 1 is a block diagram showing one embodiment of the present invention.

[0007] In FIG. 1, the parent and child telephones of this embodiment include a base unit 1 connected to a telephone line 3, and a base unit 1 connected to a telephone line 3. and handsets 21, 22, and 23 connected to the phone via an extension 4, and the base unit 1 is a telephone A line interface section 11 that interfaces with line 3 and a ring tone when an incoming call is received. a ring tone generator 12 that generates a ring tone, and a ring tone generator 12 that generates a ring tone that is sent via the telephone line 3 after going off-hook when an incoming call is received. A receiver 13 that identifies and receives the push button signal that comes, and a handset 21 to 23 are internally connected. A switch unit 16 for connecting to the telephone line 3 via the line 4 and a switch unit 16 for connecting to the telephone line 3 via the line 4. Identification from the ring tone transmitter 15 that sends the ring tone to the slave units 21 to 23 and the receiver 13 The telephone line 3 is connected to the cordless handset that has been previously associated with the push button signal received. control unit 14 that controls the switch unit 16 and controls the entire base unit 1 in order to It is composed of

[0008] Next, the operation of this embodiment will be explained.

[0009] For example, when the receiving unit 13 receives a push button signal “1”, the control unit 14 controls the If the push button signal “2” is received, the handset 21 is activated, and when the push button signal “2” is received, the handset 22 is activated. When push button signal “3” is received, connect handset 23 to telephone line 3. It is assumed that the switch section 16 is set in advance to control the switch section 16 in a specific manner.

0010 The arrival of the incoming call signal from the telephone line 3 causes the ring tone generating section 12 to sound, and the actual execution is started. When the user in the example responds by going off-hook on base unit 1, the telephone line 3 A push button signal, e.g. ” is transmitted and received by the receiving unit 13.

[0011] The receiving unit 13 notifies the control unit 14 that the push button signal “1” has been received. , the control unit 14 sends a message to the handset 21 that is previously associated with the push button signal "1". The ring tone transmitting section 15 and switch section 16 are controlled to transmit the ring tone.

0012 The control unit 16 detects that the handset 21 goes off-hook via the switch unit 16. Then, the ringing tone transmission section 15 stops transmitting the ringing tone, and starts connecting to the handset 21. The switch unit 1 connects the line to the telephone line 3 via the line interface unit 11. Control 6.

[0013] As a result, the calling party can directly talk to the called party of the handset 21. End of episode When the control unit 16 detects this via the line interface unit 11, the switch unit 16 is activated. Restore it to its original state.

[0014]

[Effect of the idea]

As explained above, the present invention allows pushbuttons to be sent from the telephone line to the base unit after off-hook. It has a receiving section that identifies and receives a push button signal, and a push button signal that the receiving section identifies and receives. The type of the push button signal is determined and the type of the push button signal is determined in advance. A connection control means that automatically connects a handset to a telephone line after answering by sending out a ring tone. By having , the caller can directly call the target handset and talk. effective.
