Abstract

PURPOSE:To avoid useless communication by providing a facsimile terminal attribute management device to each store and forward exchange and connecting the attribute management devices by a communication line so as to form network constitution rich in the expanding performance. CONSTITUTION:In receiving an identification code of a terminal FAX-B being a communication party from a terminal FAX-A, a store and forward exchange S/F-A gives an identification code of a terminal FAX-B to a management device ATBC-A prior to the facsimile information reception from the terminal FAX-A. When the management device ATBC-A recognizes other equipment, a communication line with the management device ATBC-B of the store and forward exchange S/F-B accommodating the terminal FAX-B is set by a code of the terminal equipment FAX-B to inform the facsimile terminal attribute wof the terminal equipment FAX-A to the management device ATBC-B. The management device ATBC-An receiving the result of attribute collation from the device ATBC-B sends the result to the exchange S/F-A. Since it is not required to manage the attribute of the entire network by each store and forward exchange, the network constitution rich in the expansion performance is attained.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a facsimile store and forward network, and particularly to an attribute management system for facsimile terminals.

[Conventional technology]

Conventionally, when managing the attributes of facsimile terminals in a network where multiple storage and forwarding devices are installed, each storage and forwarding device manages only the terminals that it accommodates, and the other party's terminal is accommodated in another storage and forwarding device.

The first time the storage and forwarding device stores facsimile information and passes the facsimile information to the other device, the paper width,
When attributes such as linear density and quantization method are different, it is recognized that communication is not possible, and the communication request source is notified that communication is not possible, or each storage and forwarding device manages the attributes of facsimile terminals on the entire network, and other storage Even when a communication request is made to a facsimile terminal housed in a switching device, the storage and forwarding device that is the source of the communication request checks the attributes of the other party's terminal and determines whether communication is impossible.

[Problem that the invention seeks to solve]

In the case of the conventional attribute management described above, in the former method, the storage and forwarding device that is the request source does not check the attributes of the other party's terminal, so the storage process is performed even if communication is not possible. In addition, from the operator's perspective, since the facsimile information is stored in the storage and forwarding device that is the request source, it is determined that one communication is possible, and the operator is later notified that communication is not possible, making it difficult to handle as system t1. Since each storage and forwarding device manages the terminal attributes of the entire network, a huge number of management devices are required, and a large amount of work is also required when expanding the network.

The purpose of the present invention is to provide a highly scalable network configuration,
Another object of the present invention is to provide a management method that avoids unnecessary communication.

[Means for solving problems]

The present invention provides a facsimile terminal attribute management device in each storage and forwarding device, and connects each attribute management device with a communication line, so that each device manages only the attributes of the facsimile terminal that it accommodates, and the attributes of the facsimile terminals that are accommodated in other devices. In the case of communication, attributes are exchanged between attribute management devices prior to communication,
This facsimile terminal attribute management system is characterized in that, if communication is not possible, the requester is notified of the inability to communicate before storage processing is performed by the requester's store-and-forward.

〔Example〕

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

FIG. 1 is a diagram of a relay system according to an embodiment of the present invention.

In the diagram, FAX-A and B are 77mm terminals, S/F-
A and B are storage and forwarding devices, D is a magnetic disk device for facsimile information storage, ATBC-A and B are facsimile terminal attribute management devices, and NET is a return network that connects the storage and forwarding devices.6 First, the facsimile terminal FAX The operation will be described in the case where a communication request from terminal FAX-A to facsimile terminal FAX-8 is made from terminal FAX-A. A communication request from terminal FAX-8 is received by storage/forwarding device S/FA-A.

When storage and forwarding device S/F-A receives the identification code of terminal FAX-8, which is the communication partner, from terminal FAX-A, terminal F
Prior to receiving facsimile information from AX-A, the identification code of terminal FAX-B is passed to management device ATBC-A.

The management device ATBC-A first identifies, based on the code of the receiving terminal FAX-8, whether it is a terminal housed in its own device or a device belonging to another device. When it is determined that the device is another device, the management device ATBC-8 of the storage and forwarding device S/F-8 in which the terminal FAX-8 is accommodated uses the code of the terminal FAX-B.
The management device ATBC-8 sets up a communication line with the terminal FAX-A and transmits the facsimile terminal attributes of the terminal FAX-3 to the management device ATBC-8. -B (7):I-
The attribute of the terminal FAX-8 is checked from the code to determine whether one communication is possible.

The management device ATBC-8 notifies the management device ATBC-A of the determination result via the communication line, and communication between the management devices ATBC-A and ATBC-8 ends. Management device ATBC-
Management device ATBC-A receives the attribute matching result from 8.
transmits the result to the storage/forwarding device S/F-A. Based on the results from the management device ATBC-A, the device S/F-A notifies the terminal FAX-A that communication is possible if communication is possible, and notifies terminal FAX-A that communication is not possible. −
Notify A. If communication is possible, the facsimile information from the terminal FAX-A is stored in the magnetic disk drive OK of the storage and forwarding device S/F-A, and then transmitted to the storage and forwarding device S/F-8 by a known method. Output from the device S/F-8 to the target terminal FAX-8.

A communication network between TBCs is shown.

When confirmation of attributes is required, the storage/forwarding device S/F sends the request source terminal code and the communication destination terminal code to the management device ATBC. In the ATBC, the interface unit INT first receives an attribute confirmation request and passes the request to the control unit SC. The control unit SC sends the request source to the attribute management unit ATBM.
Pass both coats of the communication destination and read the attributes. The attribute management unit ATB manages only the attributes of the terminal itself,
If both of the communication destinations of the request source 9 are self-accommodating, the attributes of both terminals are returned to the control unit SC. If the attributes of both terminals are returned, the control unit S
At C, it is checked whether communication is possible or not, and the result is passed to the reception control unit RC.The reception control unit RC is connected to the transmission control unit SC.
The result is passed to the storage/forwarding device S/F via the interface unit UNT, and the attribute confirmation operation is completed. If the communication destination is not self-accommodated, the management unit ATBM returns an indication of the communication destination other device to the control unit SC. In case of other accommodation, control unit S
C makes a communication request to the communication destination management device ATBC to the communication control unit LC based on the communication destination code, and sends the request read from the management unit ATBM to the other party management device ATBC via the communication control unit LC and the communication network NET. Sends the original attribute and destination code.

In the partner management device ATBC, the control unit LC receives the communication from the request source via the communication network NET, and transmits the attribute of the request source and the communication destination code to the reception control unit RC. Upon receiving the request source attribute and the communication destination code, the reception control unit RC sends the communication destination code to the management device ATBM and reads out the communication destination attribute. After the reading is completed, the reception control unit RC checks the request source attribute and the communication destination attribute to determine whether communication is possible. The result is sent to the request source management device AT via the communication control unit LC and the communication network NET.
Returned to BC. In the request source management device AT13C, the verification result from the communication destination management device ATBC is received by the transmission control unit SC via the communication control unit LC.
