Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile storage and exchange system that displays to a facsimile terminal operator an alarm indicating that the storage and exchange device is under incoming call restriction.

[Conventional technology]

Until now, as shown in Japanese Patent Application Laid-Open No. 60-114062, a device in which a PB telephone is connected to a GII facsimile terminal is used, and when transmitting image data, the data is stored by the PB telephone. After sending out the exchange device, the service type is designated by the PB signal, the confirmation sound is heard, and then the terminal is switched to the facsimile terminal. In this case, if the storage and switching apparatus is under incoming call regulation, the fact is notified to the facsimile terminal operator by a regulation sound.

[Problems to be solved by the invention]

However, if a facsimile terminal that supports only a specific service is connected to the directly connected line, there is no need to specify the service type with a PB signal, and immediate image data transmission can be performed simply by operating the facsimile transmission button or one-touch button. It is possible, and the incoming call restriction sound will not be heard by the operator because the telephone is not interposed. That is,
If an attempt is made to automate the procedure up to switching to a facsimile terminal when a PB telephone is equipped with a one-touch dial, etc. built into the facsimile terminal, a facsimile tone indicating that the storage and exchange device is restricting incoming calls is used. There is a problem that the facsimile terminal operator does not know that the incoming call is being restricted because the terminal operator does not listen to it.

An object of the present invention is to provide a facsimile storage and switching system in which it is known to a facsimile terminal that the storage and switching apparatus is under the termination control even when the GII facsimile terminal is connected to the storage and switching apparatus via a directly connected line.

[Means for solving the problem]

The above-mentioned problem occurs when the facsimile terminal transmits image data.
If a line disconnect command DCN is received instead of receiving the digital identification signal DIS, which is a control signal of the G II standard, or the non-standard device signal NSF, it is recognized that the store-and-forward device is in the incoming call restriction state and an alarm is issued. Achieved by displaying.

[Action]

When a call is received from the facsimile terminal to the storage and exchange device in the incoming call restriction state, a line disconnect command DCN is transmitted to the facsimile terminal instead of a certain procedure signal from the storage and exchange device, and the facsimile terminal displays an alarm based on this. By doing so, the operator of the facsimile terminal is notified that the storage and switching apparatus is under incoming call regulation.

〔Example〕

 Hereinafter, the present invention will be described with reference to FIGS.

First, the position and configuration of the storage and exchange device in the facsimile storage and exchange system according to the present invention will be described. As shown in FIG. 2, the facsimile terminals 11 to 1n are connected to the storage and exchange apparatus 4 via the circuit switch 3, and the facsimile terminal 21 is directly connected to the storage and exchange apparatus 4. The facsimile image information from each of the facsimile terminals 11 to 1n and 21 is temporarily stored in the image data storage device 44 under the control of the main control unit 43 via the line control units 41 and 42, and is transmitted to the receiving facsimile terminal at any time. It is something that has become.

First, a case in which facsimile image information is transmitted from the facsimile terminal 21 for two pages when the storage and switching apparatus 4 is not under the incoming call restriction will be described with reference to FIG. The sequence shown in FIG. 3 and the sequence shown in FIG. 1, which will be described later, are shown for the case of a directly connected line.
Other circumstances are the same.

As shown in FIG. 3, when the transmission button (or a button equivalent thereto) is operated on the facsimile terminal 21, the line control unit 42 detects the incoming call due to the formation of the loop current and notifies the main control unit 43 of the incoming call. It is supposed to be. Based on the incoming call notification, the main control unit 43 secures an area for the received image data in the image data storage device 44 and sends a GII procedure start request to the line control unit 42. The line control unit 42 starts the GII procedure and transmits the called station identification signal CED and the digital identification signal DIS (or the non-standard device signal NSF), and then sends the digital command signal DCS (or the non-standard device setting signal) from the facsimile terminal 21. NSS) and a training check signal TCF. If the training is normal, the facsimile image information of the first page from the facsimile terminal 21 is received after transmitting the reception preparation confirmation signal CFR. Thereafter, the multi-page signal MPS is received, and the facsimile image information of the first page is transmitted to the main control unit 43. At the same time, the reception completion notification of the first page is transmitted to the main control unit 43. After storing the facsimile image information of the first page in the image data storage device 44, the main control unit 43 sends a storage completion report to the line control unit 42. The line control unit 42 confirms that the first page has been normally received, transmits a message confirmation signal MCF to the facsimile terminal 21, and then receives the facsimile image information of the second page (final page) from the facsimile terminal 21. After that, the procedure end signal EOP
, A reception completion notification is sent to the main control unit 43 together with the facsimile image information of the last page. After storing the facsimile image information of the last page in the image data storage device 44, the main control unit 43 sends a storage completion report to the line control unit 42. After the line control unit 42 recognizes that the last page has been normally received and transmits a message confirmation signal MCF to the facsimile terminal 21,
Upon receiving the line disconnection command signal DCN from the facsimile terminal 21, a line disconnection notification is sent to the main control unit 43. After the facsimile terminal 21 transmits the line disconnection command signal DCN, the line is disconnected (loop current disconnected). According to the above-described sequence, the facsimile image information from the facsimile terminal 21 is stored in the storage switching device 4.

Next, the case where the incoming call is restricted by the storage and exchange device 4 will be described with reference to FIG.
When the transmission button (or a button equivalent thereto) is operated in the main control section 43 in the same sequence as in FIG.
Is notified of an incoming call. However, at that time, if the incoming call is restricted due to the image data storage area being full in the image data storage device 44, etc.,
A disconnection request is sent to the line control unit 42, and the line control unit 42 transmits a line disconnection command signal DCN instead of the called station identification signal CED and the digital identification signal DIS (or the non-standard device signal NSF). I have. When receiving the line disconnection command signal DCN, the facsimile terminal 21 displays an alarm and disconnects the line. The alarm display allows the operator of the facsimile terminal 21 to recognize that the incoming call is being restricted.

〔The invention's effect〕

As described above, according to the present invention, even when the facsimile terminal directly calls the storage and exchange device and transmits the facsimile image information, it is determined that the facsimile terminal operates the facsimile terminal so that the storage and exchange device is under the incoming call restriction. This has the effect of making the person aware.
