Description

Apparatus for managing the operating condition of ISDN Fax}

The present invention relates to a facsimile. More specifically, when a facsimile of a facsimile data transmission fails in a facsimile used in conjunction with a comprehensive telecommunication network, a comprehensive telecommunications network is displayed for each cause and judges whether to retry. It relates to a device for managing the operating state of the facsimile interlocked with.

First, the integrated information communication network will be briefly described.

An integrated telecommunications network is a digital network that comprehensively supports voice and non-voice services.

Comprehensive information and communication networks can provide different types of information such as voice, text, and video data that can be used through public switched telephone networks (PSTN), public switched data networks (PSDN), telex networks, and fax networks. Can be converted to digital and integrated into one network at a time and transmitted.

Analogue telephones, which are common telephone methods, provide only one channel, while digital telecommunications networks, which provide two channels, allow you to use computer communications or fax at the same time as you use a telephone.

In other words, when you want to use a service that is different from each other, it is possible to perform all the operations in one integrated information network without installing a separate line for each.

In addition, since the integrated information communication network transmits and receives digital signals as it is, there is no noise and there is little sound loss, so the speed is high.

The characteristics of such a comprehensive information communication network are as follows in terms of subscribers and network providers.

First, in the existing network, the user had to separately manage the subscription fee and the service use number for each service, but in the integrated information and communication network, the management can be simplified since everything can be unified.

In addition, in spite of various communication functions and breakthrough communication capabilities, it is economically advantageous because the usage fee is relatively low.

Second, from the provider's point of view, the previous phone was difficult to expand network functions, costly to construct a network, and difficult to provide complex services. It can provide network structure and application economically.

In addition, the general information communication network is divided into basic access service (BRI) and primary rate access (PRI) according to the subscriber access method. The criterion for distinguishing BRI and PRI is line capacity, that is, bandwidth It's a car.

Meanwhile, the connection structure of the reference point and the terminal of the ISDN shown in FIG. 1 will be described as follows.

In order for a user to access a general information communication network constructed with BRI and PRI, there must be a terminal supporting the general information communication network. The terminals that can be used in the general information communication network are classified into ISDN dedicated terminals and non-ISDN terminals.

ISDN terminal refers to a terminal with an ISDN standard interface that can connect to an integrated telecommunication network. A non-ISDN terminal is a terminal without direct access to an integrated telecommunication network. It is a conventional telephone, dial-up modem, and G-3 facsimile. The back belongs to this.

These non-ISDN terminals can access an integrated telecommunication network through an ISDN terminal adapter (TA).

A general information communication network is defined as a reference point for connecting these terminals. First, between the telephone company's ISDN switch and NT1, that is, the ISDN telephone line is called 'U point', between NT1 and NT2 is 'T point', and between NT2 and TE1 (Terminal Equipment 1, ISDN application terminal) is called 'S point'. Call.

Here, NT2 corresponds to ISDN PBX switch or PRI router. Since it does not correspond to BRI, 'S' and 'T' are called 'S / T point' and 'S / T point' is an application terminal corresponding to TE1 ( S card, ISDN dedicated phone, ISDN video terminal, G-4 facsimile, etc.).

In addition, the next access point of TA is called 'R point', which is a connection point to which non-ISDN terminals called TE2 are attached. A general PC, a telephone, or a regular fax machine correspond to TE2, and TE2 devices access the ISDN network through TA. .

When the fax data is transmitted through such an integrated telecommunication network, the automatic redial function is set when the other party's fax is busy or there is no response.

However, this function alone does not know the reason for the redial from the user's point of view and cannot solve the problem.

In addition, even if re-dial continues, even if failure is expected, redialing is performed a specified number of times, so that another fax data cannot be received during that time.

Therefore, the present invention was devised to solve such a problem, and an object of the present invention is to indicate that the transmission of the fax data during the transmission of the fax data in the facsimile used in connection with the integrated information communication network fails by cause. The present invention provides an apparatus that enables a user to easily identify and cope with a cause of a transmission failure of a fax data by determining whether or not a retry is attempted.

In the facsimile used in connection with the integrated information communication network of the present invention for achieving the above objects, the device for managing the operating state of the facsimile interlocked with the integrated information communication network is operable to transmit the fax data from the facsimile to the other party facsimile A detector for detecting an operating state of the facsimile occurring during execution; A storage unit which stores information on an operating state of the fax detected by the detection unit; A converting unit converting the information relating to an operation state of the facsimile stored in the storage unit into a predetermined output form; And a control unit which stores information on the operating state of the facsimile detected by the detecting unit in the storage unit and outputs the operating state information of the predetermined type converted through the converting unit.

Optionally, the display unit further includes a display unit for displaying the information regarding the operating state of the fax stored in the storage unit to the user of the fax in the predetermined form after being detected by the detection unit.

Preferably, the information about the operating state of the facsimile is a layer 1 state for controlling the signal channel of the facsimile in the integrated information communication network; State of Layer 2 for data linking with the other facsimile; And a layer 3 state confirming communication possibility with the counterpart facsimile.

Advantageously, the predetermined form separately identifies each state of layer 1 for signal channel control of the facsimile, layer 2 for data linking with the other party facsimile, and layer 3 for confirming communication capability with the other facsimile facsimile. It is a form that represents.

Hereinafter, the objects, features, and advantages of the present invention described above will be described in more detail with reference to preferred embodiments of the present invention shown in the accompanying drawings.

2 is a block diagram showing the structure of a terminal device that is linked to the integrated information communication network to carry out the present invention.

As shown, the central processing unit 10 controls the overall terminal device in accordance with the set program.

The memory 20 stores program data, protocol data, text data, and work contents related to transmission and reception, and accesses or stores data under the control of the CPU 10.

The scanner 30 scans the data of the document, converts the data into digital image data, and provides the data to the central processing unit 10.

Under the control of the central processing unit 10, the modem 70 modulates and outputs the output data of the central processing unit 10 in an analog form, and demodulates and outputs the analog input signal.

The printer 40 prints the fax data received by the control signal from the central processing unit 10.

Meanwhile, the computer interface unit 50 connects the terminal device to the computer. The connection method uses a serial connection or a parallel connection method, which is a peripheral device connection method of a computer. The serial connection method uses a COM port, which is a serial port of a computer. By using the RS-232C method, which is an asynchronous communication method, communication with peripheral devices is supported.

In addition, the parallel connection method is mainly used when connecting to a device such as a printer or plotter, and is a method commonly used for a device for transmitting data in one direction.

The pixel conversion unit 60 converts the image information input from the scanner unit 30 so as to be suitable for fax transmission / reception.

The serial input / output device (SIO) 90 performs a function of converting data input from a computer or a scanner into a form suitable for the B channel of the integrated information communication network.

That is, the data inputted through the internal bus of the system is converted into serial data form and transmitted to the integrated information communication network subscriber access controller (ISAC: short term 'ISAC') 100, and from the ISAC 100 It converts the received serial data into parallel data which is an internal bus data transmission format and transmits the serial data to the central processing unit 10.

The integrated information network subscriber access controller (ISAC) 100 performs line coding and line activation / deactivation functions, which are integrated layer 1 functions, for the D channel control, and the link access procedure on th D-channel (LAPD) function, which is a layer 2 function. And checks the possibility of communication by investigating the path setting and the property of the partner corresponding to the channel selection and setting, which is the layer 3 function, and the state corresponding to the dial, and transmits / receives data through the integrated information communication network line interface 110. It performs the function.

Here, the layers of the protocol will be described in detail.

First, Layer 1 is the shape of an 8-pin modular connector used as a socket for the physical layer, the waveform of the transmission signal on the subscriber line, the time division multiplexing of the B and D channels to a pair of subscription lines, and the bus connection. The contention control of the D channel signal is specified.

Layer 2 also implements a multi-link access protocol that allows multiple data link connections to be established on one physical layer to service bus connections to the data link layer.

This protocol is called Link Access Protocol on the D-channel.

Originally based on High Level Data Link Control (HDLC), it is possible to transmit signals with high reliability.

In addition, Layer 3 is a protocol of Layer 3, which is a set of call control performed on the D channel so that the B channel or the D channel can communicate with the network layer.

In the circuit-switched system, the possibility of communication is checked by examining the channel selection and setting, the path setting for the state corresponding to the dial, and the other party's attributes when the call is set up.

In the case of a B channel packet, only the communication channel is selected and set in the D channel and the other terminal is selected, and the call setup in X.25 is performed using the channel set as described above.

The integrated information communication network line interface 110 interfaces the signals of the integrated information communication network to transmit / receive digital data configured in the form of transmission signals according to physical standards and electrical standards.

3 is a block diagram illustrating a configuration of an apparatus for managing an operating state of a facsimile interworking with a comprehensive information communication network according to the present invention.

The control unit 81 stores the information on the operating state of the fax detected by the detection unit 85 in the storage unit 82 and prints it to the conversion unit 83.

The storage unit 82 stores information about an operating state of the facsimile detected by the detection unit 85.

The conversion unit 83 outputs information regarding the operating state of the facsimile stored in the storage unit 82 in a predetermined form.

The display unit 84 displays, in a predetermined form, the user of the facsimile the information on the operating state of the facsimile stored in the storage unit 82 to be stored after being detected by the detector 85.

The detection unit 85 detects an operation state of the facsimile which occurs during the operation for transmitting the fax data from the facsimile to the counterpart facsimile.

Hereinafter, an operation of an apparatus for managing an operating state of a facsimile interworking with the integrated information communication network of the present invention will be described in detail with reference to FIGS. 1 to 5.

First, when fax data is transmitted to the other party's facsimile interworking with the integrated information communication network, the number of times to redial and redial is set, and then the other party's facsimile is dialed (step: S1).

After the dialing, the detection unit 85 determines whether the layer 1 is activated (steps S2 and S3).

After the determination, the state information of the layer 1 determined by the detector 85 is stored in the storage 82 according to the control signal of the controller 81 (steps S4 and S5).

After the storage, the display unit 84 displays the state information of the layer 1 according to a user's request (step S20).

If the state is activated in the layer 1, the detection unit 85 determines whether the data link of the integrated information network protocol layer 2 is established (steps S6 and S7).

After the determination, the state information of the layer 2 determined by the detection unit 85 is stored in the storage unit 82 (steps S8 and S9).

After the storage, the display unit 84 displays the state information of the layer 2 according to a user's request (step S21).

If the data link is established in the layer 2, the detection unit 85 determines whether the call establishment of the counterpart facsimile and the integrated information network protocol layer 3 is made.

After the determination, the state information of the layer 3 determined by the detection unit 85 is stored in the storage unit 82 (steps S12 and S19).

After the storage, the display unit 84 displays the state information of the layer 3 according to a user's request (step S22).

In this case, when the call setup that is the layer 3 is not made, information on the cause of the call setup is not detected (step: S13), and repeated by the set number of re-dialations (step: S14). .

After performing the above steps, it is determined whether to output the contents of the storage unit 82 storing the information on the layer 1, layer 2 and layer 3 (step: S17), and according to the present invention The contents stored in the storage unit 82 regarding the operating state of the facsimile are output in a form representing the states of the layers 1, 2, and 3 separately as shown in FIG. 5 (step S18).
