Abstract

PURPOSE:To execute an allotting action only when an addressed terminal equipment is not used and to shorten an allotting time by receiving information whether a facsimile terminal is in using or not from a line switching system storing a facsimile telegraphic message, and executing an exchange control. CONSTITUTION:An address analyzing device 6 of a facsimile store and forward exchange 1 receive the information of an terminal condition whether an accommodated facsimile terminal is in using or not from a line switching system 2. The exchange 1 receives a telegraphic message from a transmitting side facsimile terminal 3, and after storing it, allot the telegraphic message to a receiving facsimile terminal 4. In such a case, a telegraphic message store and forward exchange 5 receives the information that the terminal 4 is not in using from the address analyzing device 6, executes a allotting action, and when the terminal is in using does not execute the allotting action. Consequently, the useless allotting can be stopped, the allotting time is shortened, and the line using efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a distribution system for a facsimile storage and exchange, and particularly to a distribution system for transmitting information from a facsimile storage and exchange to a destination facsimile terminal.

[Conventional technology]

Conventionally, when this type of facsimile storage/switching machine delivers stored messages to a destination facsimile terminal, the delivery operation is performed regardless of whether the destination facsimile terminal is in use or not, and if the destination facsimile terminal is in use, the delivery operation is performed at regular intervals. It is done repeatedly.

[The problem that the invention attempts to solve]

The distribution method of the conventional facsimile storage and forwarding machine mentioned above is
The delivery operation is performed even if the destination facsimile terminal is in use, so when sending to a facsimile terminal that is frequently used, the number of invalid calls due to the other party being in use increases, and the line usage rate of the facsimile storage and switching equipment increases. The drawback is that the call rate of upstream facsimile storage and switching equipment also increases.

That is, since the distribution operation cannot be performed in a timely manner when the terminal is not in use, there is a drawback that it takes time for the accumulated messages to be distributed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile storage and exchange distribution system that shortens such distribution time.

[Means for solving problems]

The distribution system of the facsimile storage and forwarding device of the present invention includes a destination analysis device that receives information from a line switch about whether a facsimile terminal is in use or not, and a message storage and forwarding device that controls the storage and exchange of facsimile messages. When installed in a device switching device and delivering stored messages to a destination facsimile terminal, the message storage and switching device receives information on whether the destination facsimile terminal is in use or unused from the destination analysis device, and transmits the message to the destination facsimile terminal. is configured to perform a distribution operation only when it is not in use.

〔Example〕

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

FIG. 1 is a relay system diagram centered on a facsimile exchange device for explaining one embodiment of the present invention.

As shown in FIG. 1, the facsimile storage and forwarding device 1 includes a message storage and forwarding device 5 and a destination analysis device 6 connected to the message storage and forwarding device 5, and a facsimile terminal (sending side) 3 and a facsimile terminal ( (receiving side) 4 is connected to a line exchange 2 which accommodates the receiving side) 4. The facsimile storage/switching device 1 receives the message from the sending facsimile terminal 3, multiplies it by N, and then delivers the message to the receiving facsimile terminal 4. In this case, the message storage/exchange device W5 receives information from the destination analysis device 6 that the facsimile terminal 4 is not in use and performs a delivery operation, and upon receiving information that the facsimile terminal 4 is in use, performs a delivery operation. Do not do this. On the other hand, the line exchange 2 is connected to the facsimile terminal 4 housed therein.
Information on the status of the terminal, such as whether it is in use or not, is transmitted to the destination analysis device 6 of the facsimile storage and exchange 1.

FIG. 2 is a block diagram of the destination analysis device explained in FIG. 1.

As shown in FIG. 2, the destination analysis device 6 includes an exchange information input device 7 from the circuit exchange, a terminal information editing circuit 8, and a terminal information output device 9 that sends out information to the message storage and exchange device.
It consists of

First, when terminal status information is sent from a circuit exchange to the destination analysis device 6, the exchange information input device 7 of the analysis device 6 receives information from the exchange without controlling the procedure with the exchange. do. Next, the exchange information input device 7 sends the received information to the terminal information editing circuit 8, which converts the formats 1 to 1 so that the received information can be sent to the message storage and exchange device 5 of the facsimile storage and exchange device 1. It is sent to the output device 9. Next, it controls the procedure between the terminal information output device (facsimile storage and exchange device) and the message storage and exchange device 5, and sends out the terminal status information.

〔Effect of the invention〕

As explained above, the distribution method of the facsimile storage/switching device according to the present invention is that when the facsimile storage/switching device distributes to a destination facsimile terminal, the distribution operation is performed when the destination facsimile terminal is not in use, and the distribution operation is performed when the destination facsimile terminal is in use. By not doing this, you can stop unnecessary transmissions from the facsimile storage and exchange.
This has the effect of increasing the line usage efficiency of the facsimile storage and switching machine by 1, and also increasing the reliability of the communication of the facsimile storage and switching machine because even if the usage rate of the destination facsimile terminal is high, it can deliver data when it is not in use.
