Abstract

PURPOSE:To transmit the will of the user of an extension telephone set held to a user who has by permitting a main equipment to release the hold state of the extension telephone set if it inputs a holding state release request signal from the extension telephone set which was in a hold state. CONSTITUTION:If the extension telephone set executes a holding operation which is previously regulated in an operation part 8, a main equipment control part 5 analyzes the transmitted operation and judges it to be the previously regulated holding operation, controls a channel switch 4 to hold the extension telephone set 3, hears a holding sound and disconnects a call with the extension telephone set 2. If the extension telephone set 3 executes a transmitting return operation which is previously regulated in an operation part 12, the operation is transmitted to the main equipment control part 5 through a telephone set control part 13. If the main equipment control part 5 judges that the transmitted operation is the previously regulated transmitting return operation, it controls the channel switch 4 and connects the transmitter 10 of the extension telephone set 3 held to the receiver 7 of the extension telephone set 2. Thus, the will of the user of the extension telephone set held can be transmitted to the user who has held.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a button telephone device.

[Conventional technology]

In conventional key telephone devices, only the extension telephone that has been put on hold during a mutual extension call can be released from hold and the mutual extension call can be resumed.

(Problems to be Solved by the Invention) The above-mentioned conventional button telephone device cannot release the extension telephone other than the extension telephone on which the hold operation was performed. The drawback is that it is impossible to convey intentions to the user.

[Means for solving problems]

In the button telephone device of the present invention, when the extension telephone is put on hold by the extension telephone of the other party, the main device has means for outputting a hold state release request signal requesting release of the hold state, and the main device includes: When a hold state release C request signal is input from an extension telephone that has been placed on hold, the extension telephone that has been put on hold is released from the hold state, and the handset of the extension telephone that has been put on hold is also connected to the hold state. The present invention is characterized in that it has means for forming a communication path between the handset and the handset of the telephone set.

In this way, the user who has suspended the will of the user of the put extension telephone by connecting the handset of the put extension telephone to the handset of the put extension telephone by the operation of the put extension telephone. can be conveyed to.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the button telephone device of the present invention. Extension telephones 2 and 3 are connected to a main device 1 of the button telephone device. The main device 1 is the communication path switch 4
, a main device control section 5 , and a hold sound source 14 . The extension telephone 4112 is composed of a transmitter 6, a receiver 7, an operating section 8, and a control section 9. Similarly, the extension telephone 3 is composed of a transmitter 10, a receiver 11, an operating section 12, and a telephone 11 control section. It consists of 13.

Extension telephone 2 and extension I! il During a call on extension line U with telephone 3, points A and D of call path switch 4 are connected, and point B and 0 are connected.
The points are connected. When the extension telephone 2 performs a predefined hold operation using the operation section 8, the operation is transmitted to the main device control section 5 through the telephone control section 9. When the main device control unit 5 analyzes the transmitted operation and determines that it is a predefined hold operation, it controls the communication path switch 4 to connect points A and D and between points B and 0. At the same time, connect points D and E. As a result, telephone 3 is put on hold and listens to the hold tone, and the call with telephone 2 is disconnected. When the extension telephone 3 performs a predefined call return operation on the operation section 12, the operation is transmitted to the main device control section 5 through the telephone control section 13. When the main device control unit 5 determines that the transmitted operation is a predefined call return operation, it controls the communication path switch 4 to connect point 0 and point B. As a result, the handset 10 of the telephone 3 on hold is connected to the handset 7 of the telephone 2.

〔Effect of the invention〕

As explained above, the present invention connects the handset of the put extension telephone to the handset of the put extension telephone by operating the put extension telephone, thereby controlling the intention of the user of the put extension telephone. It has the effect of being able to convey this to the user who has put it on hold.
