Description

Terminal device and method interworking with a comprehensive information communication network for executing a complex function.

The present invention relates to a terminal device, and more particularly, to a computer, and equipped with an integrated services digital network (ISDN) interface unit, which is provided in a terminal device used in conjunction with an integrated information network, and a telephone, telephone and It is about how to execute the output function at the same time when needed.

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 are available in different forms, including voice, text, and video data, which can be used through public switched telephone networks (PSTN), public switched data networks (PSDN), telex networks, and fax networks. All information can be converted to digital and integrated into one network at a time.

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.

Conventionally, two functions (eg, fax, telephone, data communication, etc.) are used by using two B-channels of an integrated information communication network in a terminal device connected to a computer and interlocked with such an integrated services digital network (ISDN). Although telephone, data communication and fax were implemented at the same time, three functions (eg, fax communication, telephone function and printing function) could not be implemented at the same time.

Accordingly, there is a disadvantage in that the function of the terminal device connected to the computer is not utilized to the maximum.

That is, a printing function or a scanning function not related to the communication network could not be used simultaneously with the functions (data communication, fax communication, telephone) interworking with the communication network.

Accordingly, the present invention was devised to solve such a problem, and an object of the present invention is to perform a computer and at the same time perform a fax and a telephone provided in a terminal device used in connection with an Integrated Services Digital Network (ISDN). The present invention also provides a method for simultaneously performing an output function or a scanning function transmitted from the.

First, with respect to the present invention will be described by taking an example of a multifunction device among the terminal devices used in conjunction with the integrated information communication network.

2 is a block diagram showing a configuration of a multifunction apparatus used in conjunction with a comprehensive information communication network according to the present invention.

As shown, the central processing unit 10 controls the multifunction apparatus overall according to the set program.

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

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

Under the control of the central processing unit 10, the modem unit 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 unit 40 prints the fax data received by the control signal from the central processing unit 10.

Meanwhile, the computer interface unit 50 connects the multifunction device to the computer. The connection method uses a serial connection or a parallel connection method, which is a peripheral device connection method of the computer, and the serial connection method uses a COM port, which is a serial port of the computer. It supports connection with external modem by communicating with peripheral device by RS-232C method which is asynchronous communication method.

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.

On the other hand, the pixel conversion unit 60 converts the image information input from the scanner unit 30 to be suitable for fax transmission / reception.

In addition, 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.

The Channel Access Control Logic 80 serves to perform both of fax, telephone and data communication functions simultaneously.

According to the present invention, the multifunction device 130 sets a communication function, a computer function, and a multifunction function performed in the multifunction device and generates a control signal for an operation corresponding to an input signal.

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.

The determination is possible by comparing and determining the value stored in the function storage unit 134 in the function control unit 131.

As a result of the determination, when the set function is a complex function, the memory unit 20 is divided by a size required when performing the complex function (step S300).

After the dividing, the function detecting unit 133 determines whether a ring or a hook off signal generated in the multifunction apparatus is detected (step S410).

That is, it is determined to perform a communication function. When the ring or hook-off signal is detected, an empty channel is selected from the B1 and B2 channels of the integrated information communication network to perform the detected function (telephone or fax) ( Step: S420).

Here, when the stop 139 shown in FIG. 5 is not input, if a ring or hook-off signal is detected while performing the detected function, the remaining function of the B1 and B2 channels is used to perform the corresponding function. Perform.

In addition, if both B1 and B2 channels are busy, the device waits for a predetermined time.

After performing the communication function, the function detection unit 133 determines whether a print signal or a scanning signal executed in the computer is detected (step S510).

When the print signal or the scanning signal is detected, the function control unit 131 generates a control signal for the operation of equipment corresponding to the print signal or the scanning signal even when the communication function is being performed.

During the above operations, if the pause 139 shown in FIG. 5 is not input, execution of the complex function is continuously repeated (step S600).
