Abstract

PURPOSE:To prevent a repetitive calling operation by ringing a warning tone for a calling telephone set, and forming a channel at the point of time when a called data terminal becomes idle. CONSTITUTION:In a key telephone system, in the case where the called data terminal 7 is busy, when a special operation is performed from the calling telephone set 2, the data of a calling telephone set number is stored in a calling telephone set number storage part 9, and calling processing is interrupted once. When the called data terminal 7 goes to idle, a main control part 1 refers to the calling telephone set number storage part 9, and it the data is stored previously, it investigates the use state of a calling data terminal 4. Then, in the case of an idle state, it rings the warning tone for the calling telephone set 2, and connects a data communication channel between the calling data terminal 4 and the called data terminal 7. Then, after the data communication channel is formed, it deletes the date of the calling telephone set number stored in the calling telephone set number storage part 9.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a button telephone device having a local data communication function, and in particular, the present invention relates to a button telephone device having a local data communication function, and in particular, the present invention relates to a button telephone device having a local data communication function. The present invention relates to a button telephone device capable of performing local data communication without requiring any operations.

[Prior Art] When a conventional key telephone device performs local data communication,
The calling data terminal calls the called data terminal, and if the called data terminal is free, the calling data terminal and the called data terminal are connected.

[Problems to be Solved] The conventional button telephone device described above cannot establish data communication if the called data terminal is in use during local data communication, and the caller must perform the call operation until communication becomes possible. This had to be done repeatedly, resulting in a waste of time and effort.

The present invention has been made in view of the above-mentioned problems, and is a button telephone that can perform local data communication without requiring the caller to repeatedly make a call operation when the called party is unable to communicate. The purpose is to provide equipment.

"Means for Solving the Problems" - In order to achieve the object described above, a button telephone device of the present invention includes a button telephone to which a data terminal is connected via a data terminal connection part, and a main device that accommodates the button telephone. In the button telephone device, the main device includes a data terminal usage status recognition means for recognizing the usage status of the data terminal, and a calling telephone that stores a calling telephone number when the called data terminal is in use. number storage means, and data communication path connecting means for referencing the calling telephone number storage means when the called data terminal becomes vacant and connecting a data communication path between the calling data terminal and the called data terminal. The configuration includes the following.

[Example code] Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a block diagram of a key telephone device according to an embodiment of the present invention, and FIG. 2 is a diagram showing a memory state in a calling telephone number storage section in the key telephone device of FIG. 1.

In FIG. 1, 1 is a main control unit, 2 and 5 are key telephones, 3 and 6 are data terminal connection units, and 4 and 7 are data terminals. That is, the data terminal 4 is connected to the main control unit 1 via the key telephone 2 equipped with the data terminal connection 3, and similarly, the data terminal 7 is connected to the main control unit 1 via the key telephone 5 equipped with the data terminal connection 6. It is connected to the control unit l.

On the other hand, the main control section 1 has a storage section 8 that is read and written by the main control section, and this storage section further includes a calling telephone number 818 storage section 9 provided for each data terminal.

Next, FIG. 3 is a flowchart showing data storage processing when the called data terminal is in use in the button telephone device of FIG. 1, and FIG. 12 is a flowchart illustrating processing when a call data terminal becomes vacant.

Now, suppose that in the button telephone device having the above configuration, a call is made from the button telephone 2 and a call is received at the button telephone 5 in order to transmit data from the data terminal 4. In this case, the storage unit 8 recognizes the usage status of the data terminal connected to the data terminal connection unit 6. Therefore, data terminal 7
If it is not in use, a communication path will be formed, but if it is in use, it will not be possible to form a communication path.

However, if the data terminal 7 is in use, the calling phone 8!2
When a special operation is performed from , the main control section 1 performs processing according to the flowchart shown in FIG. As a result, the data of the calling telephone number is stored in the calling telephone number storage section 9 shown in FIG. At that point, the call processing is temporarily interrupted.

Next, when this called data terminal 7 becomes vacant, processing is performed according to the flow shown in FIG. That is, first, the main control section 1 refers to the calling telephone number storage section 9, and if data is stored therein, checks the usage status of the calling data terminal 4.

If the telephone is vacant, a warning tone is sounded to the calling telephone 2, and the data communication path between the calling data terminal 4 and the called data terminal 7 is connected. After the data communication path is formed, the data of the calling telephone number stored in the calling telephone number storage section 9 is erased.

In this way, this embodiment provides a key telephone device that accommodates a plurality of key telephones each equipped with a data terminal connection section and has a local data communication function. The main controller has means for recognizing the usage status of the data terminal connected to the data terminal connection part of the key telephone in the equipped room, and a means for recognizing the usage status of the data terminal connected to the data terminal connection part of the key telephone in the equipped room, and means for writing the calling telephone number into the calling telephone number storage section for each data terminal provided in the storage section by a special operation of the calling party in the case of Refers to the calling telephone number storage unit, and if the calling telephone number is stored and the calling data terminal is free, a warning tone is sounded for the calling telephone, and the calling data terminal and the called data are and means for connecting a data communication path with the terminal.

It should be noted that the present invention is not limited to the above embodiments, but includes various modifications within the scope of the gist. For example, in the above-described embodiment, when the called data terminal becomes free, a warning sound is emitted to the calling data terminal to connect the data communication path, but the warning sound is not intended to prompt the calling party to call again. , the data communication path may be connected only after the calling party performs a re-call operation.

[Effects of the Invention] As explained above, the present invention provides a warning sound to the calling telephone when the called data terminal becomes free when the called data terminal is in use in local data communication. By making the data communication path between the calling data terminal and the called data terminal connectable, the calling party is not forced to repeatedly make a call when the called party is unable to communicate. This has the effect of providing a key telephone device that is capable of local data communication.
