Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is used in facsimile communication to once accumulate manuscripts with the same content (hereinafter referred to as broadcast telegrams), and then to send a large number of the broadcast telegrams through an exchange. The present invention relates to a facsimile storage and relay device that automatically transmits data to a destination facsimile terminal.

BACKGROUND OF THE INVENTION Conventional facsimile storage and retransmission devices of this type have multiple communication channels for transmitting broadcast messages to multiple destinations, and also have the function of transmitting broadcast messages to multiple destination facsimile terminals. have.

FIG. 3 shows an example in which the facsimile storage and retransmission device is installed in a facsimile exchange network comprising a plurality of exchanges connected by trunk lines.

In FIG. 3, X1 to X4 are exchanges arranged in each area (district), and these exchanges X1 to X4 are connected to each other via trunk lines M12, M13, and M14.

Among the above exchanges, the exchange X1 has a plurality of nearest facsimile terminals F11, F12, F13, . . .
are directly connected via the office lines L11, L12, L13, . In addition, the exchange X2 has a plurality of nearby facsimile terminals F21, l? '22, F23,...
are directly connected via central office lines L21, L22, L23, . . . . Similarly, exchange X3 has a plurality of facsimile terminals P31, F32, F33, . . .
・A plurality of facsimile IJ terminals F are connected to the exchange X4 via central office lines L31, L32, L33, etc.
41, F42, F43, ... are the central lines L41, L
42, L43, . . .

Communication between different facsimile terminals in each area is performed by setting up a call through the trunk lines M12 to M14. In that case, since the distance between each exchange X1 to X4 is generally a long distance, the call capacity of each trunk line M12 to M14 should be set as small as possible according to the expected traffic (communication volume). It is normal.

By the way, in the above-mentioned facsimile exchange network (Fig. 3), when a mailing message is inputted to the facsimile storage/replying device (hereinafter simply referred to as the "replying device") S by an appropriate method, the retrieving device S transmits the corresponding station line Lsl to Lsn. Broadcast communication is performed using the maximum number of .

In that case, facsimile terminals in a single area where the broadcast destination facsimile happens to be, for example, facsimile terminals (hereinafter simply referred to as terminals) F21, F22 connected to exchange X2,
When F23,... is concentrated (unbalanced), the traffic on the trunk line M12 between exchanges X1 and X2 increases temporarily, and the traffic on the trunk line M12 increases due to communication between other terminals using the trunk line M12. A situation occurs where it becomes impossible to set up a call.

In order to avoid such a situation, in the conventional facsimile exchange network (hereinafter referred to as the conventional system) described above, the call capacity of each trunk line M12 to M14 is limited to the central office line accommodated by the broadcasting device S. It is necessary to set it considerably longer than the number of Ls1 to Lsn with some margin.

Problems to be Solved by the Invention In other words, in the conventional system in which the conventional broadcasting device S is implemented, the broadcasting device S is configured to unilaterally bias the broadcasting destination facsimiles, that is, the area to which the broadcasting destination facsimile IJ belongs. Since the system performs broadcast communication processing by utilizing its own maximum capability without considering There was a problem that the necessity arose and the economic loss was large.

Therefore, in the present invention, when a broadcast device sets up a call to a broadcast destination facsimile, it checks the number of calls for each area, and if the number of calls is less than a specified value, the call is set. An object of the present invention is to provide a facsimile storage/broadcasting device which can always efficiently set the call capacity of a long-distance trunk line without waste.

Means for Solving the Problems The technical means of the present invention for solving the above problems is a means for storing all facsimile terminals in a facsimile exchange network and each area to which each facsimile terminal belongs, and a rerouting device. The broadcast device is equipped with a means to count the number of broadcast transmission calls that the user is currently making for each area, and to set up a call if the counted number of calls is less than a specified number. .

For production The effects of the above technical means are as follows.

In other words, when transmitting a broadcast, the broadcasting device checks the area to which the broadcast destination facsimile machine (destination facsimile terminal) belongs, counts the number of calls to that area, and calculates the number of calls counted. Check whether the value is less than the specified value.

If the value is greater than the specified value, the area to which other destination facsimile terminals (destination terminals) belong is checked without performing broadcast transmission.

If it is less than the specified value, the call counter is incremented, a call is set up, and broadcast transmission is started.

The counter is decremented at the end of transmission.

Since the broadcasting device is operated in this manner, the number of calls that are simultaneously set up for a single area is always kept below a certain value. Therefore, the communication capacity of the long-distance trunk lines between the exchanges must also be kept to the minimum necessary.

Embodiment FIG. 1 is a schematic block diagram showing an embodiment of a facsimile storage/replying device according to the present invention. In the figure, 1 is a reading unit for inputting a circular message into the device, and 2 is a reading unit for inputting a message message into the device. A broadcast panel consisting of, for example, a keyboard, for inputting a designated destination terminal, etc. (hereinafter referred to as broadcast destination information); 3;
4 is a message memory for storing the broadcast message from the reading unit 1, 4 is a destination memory for storing the broadcast message destination information from the broadcast panel 2, and 5 is a control unit for controlling the entire broadcast device. The control unit 6 also has a function of comparing and determining a predetermined numerical value set in advance with the counted number of calls, which will be described later.

Reference numeral 6 indicates a terminal storage unit in which all the destination information of the broadcast messages within the facsimile exchange network that can be specified on the broadcast panel 2 is preset, and reference numeral 7 indicates a terminal storage unit in which the broadcast device performs facsimile communications (call settings, etc.) with each destination terminal. This is a communication control section for performing the communication, and is composed of a plurality of communication control units 71 to 7n. Ls1
~Lsn is each communication control unit 71 of the communication control section 7
~One exchange with one end connected to 7n and one end connected to 1 and the other end (
(See Figure 1)

Reference numeral 8 denotes a call number counter for counting the number of broadcast transmission calls currently being made by the broadcasting device itself, divided by area to which each terminal belongs, and this counter 8 is a single counter for each of a plurality of areas. 81 to 8n, and has a function of exchanging information with the control section 5.

FIG. 2 shows an example of a memory map (storage area allocation diagram) of the terminal storage unit 6.
Each area 61. stores the telephone numbers and area numbers of all terminals in the area (see figure).
62, in the telephone number area 61, the telephone numbers of all the terminals 1-1 are preset, and in the area number area 62, the area numbers to which all the terminals 1-1 belong are preset. Ru.

The operation of the facsimile storage and redirection device configured as described above will be described below.

The sender of the broadcast telegram operates the broadcast panel 2 to input broadcast destination information, and also inputs the broadcast telegram from the reading section 1.

The input broadcast destination information is stored in the destination memory 4, and the broadcast message (image information) is stored in the message memory 3.

When the above input operation is completed, the control unit 6 reads out the information in the destination memory 4 and attempts to transmit the image information stored in the message memory 3 to each designated destination terminal.

In this case, the control unit 5 first detects the belonging area number of the destination terminal read from the destination memory 4 while referring to the memory map of the terminal storage unit 60.

Next, the control unit 5 compares the content (current number of calls) of a single counter (for example, 81) of the call number counter 8 corresponding to the area number with a preset specified value (maximum value).

If the number of calls is greater than the specified value, transmission to the destination terminal is suspended, a new destination terminal is read from the destination memory 4 again, and the same check as described above is performed for that terminal.

If the number of calls is less than the specified value, it is decided to transmit to the destination terminal, and first, the control unit 6 sets the single counter ( For example, 81) is incremented. Next, the telephone number of the destination terminal is read from the terminal storage section 6 by referring to the memory map, and is transferred to one communication control unit (for example, 71) of the communication control section 7. Upon receiving this, the communication control unit 71 automatically makes a call, sets up a call to the destination terminal, and then transmits the contents (image information) of the message memory 3.

When the transmission is completed (including a malfunction in the procedure), the communication control unit 7
(Communication control unit 71) transmits a communication end notification to control section 6. Upon receiving the notification, the control unit 5 decrements the single counter 81 of the call number counter 8.

The control unit 5 is connected to which communication control unit 71 to 71 of the communication control unit 7.
It always knows whether the unit 7n is performing a communication processing operation, and always activates a unit that is not performing a communication processing operation based on the above-mentioned judgment criteria.

Then, either the transmission to all the destination terminals stored in the destination memory 4 is completed, or the broadcast communication process for one broadcast message ends due to a predetermined number of procedural failures.

Effects of the Invention As detailed above, according to the present invention, the broadcasting device is aware of the area to which the destination terminal belongs and checks the current number of calls being made simultaneously to terminals in each area. and sends only if the number of calls is less than the specified number,
Since it is equipped with a function to suspend transmission if the number exceeds a specified value, the number of calls on long-distance trunk lines between each exchange (
The number of calls (number of calls) is always limited to a certain value or less, and the call capacity of the long-distance trunk lines between each exchange can be set without waste, making it extremely economically advantageous. be.
