Abstract

PURPOSE:To utilize the facsimile store and forward exchange service by accommodating and connecting the standard facsimile group directly and allowing a call connection control section to receive service information from a service analysis section thereby executing the operation of a network. CONSTITUTION:When a call/interrupt request signal from a facsimile equipment 4 receives a call connection control section 2, the control section 2 receives a call request and reaches the state of receiving a series of numerals and facsimile picture signal. Then the control section 2 receives a series of numerals and facsimile signals inputted from the facsimile equipment 4 and transfers them to a service analysis section 3 without any modification. The analysis section 3 decides the part representing the destination among a series of received numerals and analyzes the part other than the destination as service information and implement the store/delete of the facsimile signal according to the service information. The control section 2 receives the destination/service command required for the control of the network 5 from the analysis section 3, gives a dialing to the network to start the procedure of the transmission of the facsimile signal.

Description

[Detailed description of the invention] [Industrial application field] The present invention is a facsimile [Conventional technology] The present invention relates to a storage and forwarding device.

A conventional facsimile storage and forwarding device receives service designation information transmitted as a series of numbers from a G4 facsimile device in addition to a destination selection signal to perform functional services. That is, the circuit switching device receives a call origination/disconnection request from the G4 facsimile device, controls the destination selection signal, performs a call incoming operation on the facsimile storage and forwarding device, and the facsimile storage and forwarding device interprets the service specification information. It provided a store-and-exchange service.

[Problem to be solved by the invention]

The conventional facsimile storage and forwarding device described above is configured to execute a service by receiving service designation information, which is information other than the destination selection signal that controls the switching network transmitted by the G4 facsimile device. Standard G4 facsimile terminals that do not have the transmission function cannot use the facsimile storage service, which poses a problem that limits the spread of the facsimile storage and forwarding service.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile storage and forwarding device that solves the above problems.

[Means to solve the problem]

The facsimile storage and forwarding device according to the present invention is a CCITT
A call connection control unit that directly accommodates and connects a standard group 4 (hereinafter G4) facsimile machine according to the recommendation, sends and receives signal and data information, executes call connection control procedures, and transfers and outputs a received series of numerical information. and a service analysis unit that analyzes a series of numerical information received from the call connection control unit as service designation information of a store and forward service and outputs service information.

[Effect]

Therefore, the facsimile storage and forwarding device according to the above means directly accommodates and connects standard 04 facsimile devices, and the call connection control section receives service information from the service analysis section and executes operations on the network side.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the facsimile storage and forwarding device of the present invention. Facsimile storage and forwarding device 1
houses a standard G4 facsimile machine 4. Standard G
The call connection control unit 2 performs operations in response to a call request from the facsimile machine 4, receives a series of numerical information as service designation information in the same way as a destination selection signal, and controls the process up to the disconnection operation. The service designation information received by the call connection control section 2 is interpreted as a service by the service analysis section 3 and stored. When the service analysis unit 3 completes the interpretation of the service, the service analysis unit 3 activates the call connection control unit 2, and the call connection control unit 2 operates on the network 5.

The functions of the facsimile storage and forwarding device when communicating by specifying a service from a standard G4 facsimile device will be described with reference to FIG.

First, the signal for call control issued from the facsimile machine (
The call origination/disconnection request signal) is received by the call connection control unit 2,
After receiving the call request, the call connection control section 2 enters a state in which it receives a series of numbers and a facsimile image signal. Next, the call connection control section 2 receives the series of numbers input from the facsimile machine and the facsimile signal, and transfers them as is to the service analysis section 3. The service analysis unit 3 separates the part indicating the destination from the received series of numbers. Next, the service analysis section 3 analyzes the parts of the series of numbers other than the destination as service information, and stores/deletes facsimile signals according to the service.

The call connection control unit 2 connects the service analysis unit 3 to the network 5.
After receiving the destination/service instructions necessary for controlling the machine, a call is made to the network and the facsimile signal transmission procedure begins. The series of numbers mentioned here should normally be numbers that the network can recognize as a destination, such as the destination of the receiving terminal, but in this method, the service specification information is input in succession along with the destination, so communication with the network is started. First, it is necessary to separate the destination using the facsimile storage and forwarding device.

Next, an example of inputting a series of numbers from a terminal device will be shown.

The first example is numeric information 12.34 (destination) 56789012 when entering only numbers and setting the first 4 digits as the destination.
(service specification information), and the number of digits of the destination is fixed and divided by the storage and forwarding device.

The second example is when entering numbers, the code #, and ku, and the numerical information 1234 (destination) ku (delimiter) 567890 #1
2 (service specification information), the destination and service information are separated by an encoder.

〔Effect of the invention〕

As explained above, the present invention treats a series of numerical information sent from a standard G4 facsimile machine as a destination selection signal as service designation information. Standard G4
The facsimile device can use the facsimile store and forward service that is not available, and there is no restriction on the 04 facsimile device when using the facsimile store and forward service, and the network can be expanded.
