Abstract

PURPOSE:To accurately recognize the line function state by analyzing a response to a line function state check request from a network. CONSTITUTION:The CPU of a main control part 1 executes the processing in accordance with a control program by power application information, operation information, and stored data of a memory 4 and controls the transmission of a line function state check requesting command 7, the reception and the analysis of a response to this command, and output from a printer 2, etc. The line state check requesting command 7 to the network is sent, and the response 8 from the network is analyzed and results are reported to an operator, thus checking the line function state at the time of power application (automatically) and any time (manual). Control contents include the display of 'checking of line function state' on an LCD 3 at the time of waiting for the response from the network and the emission of a prescribed tone for checking error from a speaker 6 at the time of the end of report output. Thus, the line function state is accurately recognized.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ISDN communication device, and more particularly to an ISDN communication device equipped with a function capable of checking the status of each function of an ISDN network.

(Prior technology) ISDN (Integrated Digital Network) as a digital line network
In the service network, a plurality of ISDN terminals, such as G4 facsimile machines, can be connected to one subscriber line, and various services can be provided.

In ISDN, 1-to-n wiring (bus wiring) is defined as one of the wiring forms in the basic interface. In other words, bus wiring is also possible with the ■interface, and with the 1-to-n wiring described above, it is possible to connect up to 8 terminals, and sockets are provided at the connection points with the bus, so you can connect any Communication is possible even if the connector is inserted into the socket.

In this way, the ISDN communication device is portable (ensures mobility and portability) and can be connected/disconnected from the network side by connecting/disconnecting the connector, making it easy for the user.

Furthermore, various functions can be registered in the ISDN network, and this is one element that increases the usefulness of the various services provided by the ISDN.

(Problem to be Solved by the Invention) However, there is a possibility that errors in connector connection or non-registration of functions on the network side may occur, and if an abnormal state due to such causes occurs in a communication device, In the past, it was only when an abnormal condition occurred when trying to perform a certain operation that it was discovered that the cause was on the line side. Even in the RP being used, it is not possible to know the status of the ISDN line function at that time, and in this respect, especially when portability is high as mentioned above, there are various problems such as whether it is easy to connect/disconnect to the network side using a connector. I connect to ISDN where functions can be registered.
There is room for improvement as a communication device for SDN.

The object of the present invention is to provide an ISDN communication device of this type,
An object of the present invention is to provide an ISDN communication device that allows the status of ISDN line functions to be easily and accurately grasped.

(Means and effects for solving the problems) In order to achieve the above object, the present invention is an ISDN communication terminal connected to an ISDN S or IR interface, which sends a line function status check request to the network. It has a function to analyze the response from the network in response to the request and notify the result, and allows the operator to check the status of the line function based on the request sent. This system is designed to appropriately recognize and display the status of ISDN line functions.

(Example) Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment in which the present invention is applied to a facsimile machine.

In the figure, the facsimile machine is operated by a main control unit 1 consisting of a CPU, etc., and a printer 2, for example.

In addition to having an LCD 3 as a display provided in the display unit, this embodiment also includes a memory 4 in which information such as function codes to be described later is stored in advance, an analysis unit 5 for a response from the network, and a speaker 6. We are prepared.

Although not shown, a facsimile usually has an operation section with various switches operated by an operator (user), a reading optical system, a reader consisting of a CCD line sensor, etc. .

Document information can be sent and received using S connected to the ISDN line.
Alternatively, it is done via an interface.

Here, S or T interface refers to CC as an interface between the network and user premises equipment.
It has been standardized by the ITT and is collectively called the I-interface, and ISDN's facsimiles are used by being connected to such an interface of ISDN.

The printer 2 may be of a thermal recording type, for example, and is used not only to print out received images but also to print out check response analysis results as described later. That is, as will be described later, the line function status check request command 7 is issued from the facsimile machine to the network side automatically when the power is turned on, and manually at any time by the operator's operation. A line function status check response 8 is sent to the facsimile machine. When such a response 8 is returned, when the analyzer 5 compares the information with the information stored in the memory 4 and analyzes the result, the printer 2 outputs the result. It is designed to be printed out.

Regarding sending command 7, when doing this manually,
For example, it is possible to adopt a configuration in which a function button or the like for the request is provided on the operation section and the request is made by this button.

FIG. 2 shows an example of function code definitions stored in the memory 4. As shown, items corresponding to the codes in the left column of the figure are set, and these are stored as data.

In the main control unit 1, a control program as shown in a flowchart described later is stored in the program storage unit in advance, and the central processing unit (CPU) of the main control unit 1 stores power-on information and operation information by the operator. , executes processing according to the control program based on the data stored in the memory 4, etc., and controls the transmission of the line function status check request command 7, the reception and analysis of the line function status check response 8, and the output of the result by the printer 2. I do.

In this way, in this embodiment, by providing a means to issue a request to the network to check the line function status 7, analyze the response 8 from the network, display the result, and notify the operator, it is possible to turn on the power after moving the device, etc. The status of the line function is checked at certain times (automatically) and at any time (manually).

In addition, the above-mentioned control contents include the display on the LCD 3 indicating "Checking the line function status" when waiting for a response from the network, and the generation of a predetermined sound on the speaker 6 at the time of a check error, at the end of report output, etc. can also be included.

A more specific explanation will be given below with reference to FIGS. 3 and 4.

FIG. 3 is a flowchart showing the operation of the tree terminal,
It shows the processing contents to enable checking the status of the line function at any time when the FFI investment is made, and Fig. 4 shows the check response analysis results in that case. An example of a report format is shown.

In Fig. 3, if the corresponding state is reached (step 301) when the power is turned on after installation (automatic) after installation due to reasons such as moving the device, or by operation (manual) at any time (step 301), the facsimile machine C of main control unit l
The PU issues a line functional status check request command 7 to the network side (step 302).

When a line function status check response 8 is returned from the network in response to this request (step 303), the analysis unit 5 performs analysis (step 304).

That is, the analysis unit 5 analyzes the code by comparing it with the code shown in FIG. 2 stored in the memory 4, and as a result, the third
The printer 2 outputs a report as shown in the figure (step 305).

In this manner, according to the method of this embodiment, the terminal checks the functional status of the line when the power is turned on and at any other time, and this can be known by outputting the report. In other words, by equipping this facsimile machine as an ISDN communication terminal with the function of requesting the network to check the line function status and the function of analyzing the response from the network and displaying the results, it is possible to connect to the network side using a connector with high portability. / An easy-to-connect ISDN communication device can know the status of ISDN line functions, in which various functions can be registered, when the power is turned on during installation or at any other time. This can be done by utilizing the printer 2, and the operator can accurately grasp the status of the ISDN line function at the time, and it is difficult to identify the cause of the problem until an abnormal condition occurs when trying to perform the operation described above. There is no inconvenience of finding out what is happening on the line side.

Further, in this embodiment, during the above process, the LCD 3 displays "Checking line function status" while waiting for a response from the network, and furthermore, when the speaker 6 has a check error due to some reason or when the report output is finished, It is designed to emit sound, making it even more convenient.

Note that the present invention is not limited to the above-mentioned embodiments. For example, there is a method of simply displaying the report on the LCD for a certain period of time without using a printer to print out the report. Such a method may also be used.

(Effects of the Invention) According to the present invention, an ISDN communication terminal connected to an ISDN S or T interface has a function of sending a line function status check request to a network and a response from the network in response to the request. It has a function to analyze and notify the result, and it is possible to check the status of the line function based on the above-mentioned request transmission, so it is possible to check the status of the line function of ISDN, which can register various functions. In particular, ISDN has high portability and can easily be connected/disconnected to the network side using a connector.
It is suitable as a communication device, and if it is possible to know this when the power is turned on and at any other time, it can be done automatically at the time of installation, etc., and at any time during use, which is more effective. There are other advantages.
