Abstract

PURPOSE:To send a data in matching with the characteristic of an opposite terminal equipment by providing a teletex terminal equipment and a facsimile terminal equipment in an equipment so as to allow a reception opposite party to identify automatically whether the terminal equipment is the teletex terminal equipment or the facsimile equipment. CONSTITUTION:A reply signal demodulated by a teletex MODEM 4 and a facsimile equipment MODEM 5 is given to a teletex procedure control section 6 and a ficsimile procedure control section 7. When the reply signal is an MCI signal (by the CCITT recommendations), since the teletex procedure control section 8 can analyze the signal, it is recognized by the opposite party to be the teletex terminal equipment, and the succeeding procedure control is advanced by the a teletex procedure control section 6. When the reply signal is a DIS signal (by the CCITT recommendations), since the facsimile procedure control section 7 can analyze the signal, the opposed party is recognized to be the facsimile terminal equipment and the succeeding procedure control is advanced by the facsimile procedure control section 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a terminal for a data communication device, and more particularly to an automated composite terminal having a teletex terminal and a facsimile terminal in one device.

(Prior Art) Conventionally, a teletex terminal and a facsimile terminal have been created as separate terminals, and for example, it has been impossible to directly send data from a teletex terminal to a facsimile terminal.

(Problems to be Solved by the Invention) In the conventional teletex terminal or facsimile terminal described above, the transmission control procedure and the structure of the transmitted data are completely different. It is not possible to send the information directly to the facsimile terminal, and there is a disadvantage in that, for example, it is necessary to send the data once outputted to recording paper at the sending end again from the facsimile terminal.

An object of the present invention is to have a teletex terminal and a facsimile terminal in one device, to simultaneously monitor the teletex and facsimile sent from the other party's terminal, and to convert this signal into a teletex MCI signal ( CCITT), the other party is determined to be a Teletex terminal, and the procedural signal sent from the other party's terminal is DI.
To provide a composite terminal configured to have busy compatibility with teletex and facsimile by eliminating the above-mentioned drawbacks by determining that the other party is a facsimile terminal when there is an 8 signal (by COITT).

(Means for Solving the Problems) A composite terminal according to the present invention includes modem means for controlling teletex procedures, modem means for controlling facsimile procedures, 1 procedure control/
The cutting section is constructed by comprising a means and an adaptive conversion/transmission means.

The teletex procedure control modem means is for functioning as a teletex terminal.

The facsimile procedure control modem means is for functioning as a facsimile terminal.

The procedure control deadline is to detect/recognize whether the receiving terminal is a Teletex terminal or a facsimile terminal by receiving an MCI signal in the procedure when sending facsimile image data or Teletex character data. This is for separating signals.

The adaptive conversion/transmission means is for adaptively converting the transmission data in accordance with the destination terminal and transmitting the data.

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

FIG. 1 is a block diagram showing an embodiment of a composite terminal according to the present invention.

In No. 11g, l is a line, 2 is a network control unit, 3 is a signal cutter, and 4 is a teletex modem.

5 is a facsimile modem, 6 is a teletex procedure control section, 7 is a facsimile procedure control section, 8 is a character data input section, 9 is a character/image conversion i, IO is a facsimile encoding section, 11 is an image data input section, 1no is a procedure control/distribution means, and 200 and 300 are procedure control modem means.

When a call is made from this device, the procedural response sent from the other party via the line lt is sent to the network control unit 9. After the signal passes through the device 3t, it is simultaneously input to the teletex modem 4 and the facsimile modem 5. In the teletex modem 4 and facsimile modem 5, the demodulated response signals are input to a teletex procedure control section 6 and a facsimile procedure control section 7. At this time, the response signal is M
If it is a CI signal, the signal can be analyzed by the teletex procedure control unit 6, so it is recognized that the other party is a teletex terminal, and the subsequent procedure control is then carried out by the teletex procedure control unit 6.

On the other hand, if the response signal is a D18 signal, the facsimile procedure control unit 7 can analyze the signal, recognize that the other party is a facsimile terminal, and proceed with subsequent procedure control by the facsimile procedure control unit 7.

As described above, after recognizing whether the other party's terminal is a teletex terminal or a facsimile terminal, the data to be sent is character data input from the character input section 8, and the other party is a teletex terminal. In this case, the signal is sent as is.

On the other hand, if the other party is a facsimile terminal,
After the character data is converted into a bit pattern by the character/image conversion section 9, it is input to the factor 5 encoding section 10 and transmitted to the other party as facsimile data.

Conversely, the data to be sent is input at the image data input section 11.
% If the other party is a facsimile,
Send it as is, but if the other party is a Teletex terminal, what about the image data? Since it cannot be uniquely converted into character data, the operator is notified of this fact.

(Effects of the Invention) As explained above, the present invention automatically identifies whether the receiving party is a teletex terminal or a facsimile terminal by having a teletex terminal and a facsimile terminal in one device. However, it has the effect that data can be transmitted in accordance with the characteristics of the other party's terminal.

Claims (1)

[Claims] A modem means for controlling teletex procedures to function as a teletex terminal; a modem means for controlling facsimile procedures to function as a facsimile terminal; Is it a terminal?
Alternatively, there is a procedure control/separation means for detecting/recognizing whether it is a facsimile terminal by receiving a procedural MCI signal and separating the signal, and a means for adaptively converting the transmission data according to the other party's terminal and sending it out. 1. A composite terminal comprising adaptive conversion/transmission means.
