determine whether to go off-hook and respond (S5),
If there is no response, it is determined that the G3 facsimile 2 is not connected, and the process for when there is no response is performed (S6). Also, if there is a response from the G3 facsimile 2 in S5 above, the G3
The data is transferred to facsimile 2 (S7).

(Problem to be Solved by the Invention) However, in the conventional data storage type G3 facsimile adapter 3, communication is completed when data is received from the network 1 and storage is completed, and the sending side also receives the data at that point. It is determined that the transmission and reception of the data has been completed. After this determination, the connection of the G3 facsimile 2 is confirmed using the calling method described above, and communication between the G3 facsimile adapter 3 and the G3 facsimile 2 is started, so it is difficult to determine whether the G3 facsimile 2 is securely connected. , after determining that data transmission and reception through network 1 has been completed.

Therefore, if G3 facsimile 2 is not connected to 03 facsimile adapter 3, G3
Even if data reception and storage are completed in the facsimile adapter 3, the data may not be transferred to the user's G3 facsimile, and this is a problem that cannot be detected even on the sending side.

In view of the above, an object of the present invention is to provide a data storage type G3 facsimile adapter capable of detecting whether a G3 facsimile is connected to a network.

(Means for Solving the Problems) The present invention achieves the above-mentioned purpose by providing an I
In a data storage type 03 facsimile adapter used in a facsimile communication system that communicates with a G3 or G4 facsimile using an SDN network, a detection unit that detects a connection between a user's 03 facsimile and the data storage type G3 facsimile adapter; and set the result to 0
This is achieved by a G3 facsimile adapter that includes a G3 facsimile interface control section provided in the G3 facsimile adapter and a notification section that notifies the user's G3 facsimile.

(Function) According to the configuration of the present invention described above, the detection unit confirms the connection of the G3 facsimile at the time of system initialization, and the notification unit notifies the G3 facsimile interface control unit and the user, thereby providing reliable data. Communication becomes possible, and if the connection is not confirmed, it waits until it is confirmed, thereby eliminating waste such as data accumulation and enabling data communication without error reception.

(Example) Embodiments of the present invention will be described below with reference to the drawings.
