In recent years, with the remarkable spread of data communications, there has been an increasing demand for communication between data terminals that transmit and receive data using different code systems in a data exchange network, for example.
In response to the above requirements, for example, a code system for transmission data is established within a data exchange network, and this code system is positioned as a standard code system within the network, and transmission data from a sending terminal is transmitted through the data exchange network. The data exchange equipment that makes up the network converts the data into the standard code system described above and transmits it within the network, and then to the receiving terminal, it converts from the standard code described above to the code system that the receiving end does not have. A method that enables data communication between terminals in a code system, or a method in which a data exchanger in a data exchange network receives the code system of a sending terminal without establishing a standard code system within the network as described above. Methods are being considered or implemented to enable data communication between terminals with different code systems by providing a function to directly convert the code system of the terminal.

In general, data exchange equipment in a store-and-forward type data exchange network accommodates communication lines with multiple data terminals, and includes a communication control function as a component for controlling communication procedures such as transmission control procedures with the terminals. It is composed of: In that case, the communication control device responsible for the above-mentioned communication control function and the exchange processing device that performs data exchange processing in units of data blocks, etc., which are sets of character strings transmitted and received by the communication control device, are separated. In some cases, a single processing device may be used to perform the above communication control function and switching processing functions. As shown in FIG. 1, the above-mentioned communication control device or communication control function includes a character processing section 130 that controls transmission control in character units such as detection and addition of transmission control characters; Transmission data is transmitted in units, and each communication line includes a line accommodation section 110-i (i=1, 2,...n) that includes a so-called serial-parallel switching function that transmits data in bit serial format.

However, when performing the code conversion in a data exchange or the like configured as described above, character-level transmission control processing such as detection and addition of transmission control characters in the conventional character processing unit 130 is performed by each transmitting/receiving terminal. Code conversion is carried out in accordance with the code system, and code conversion for transmission data is performed after a reception data transmission block is assembled by the character processing unit 130 when data is received from the line, and when data is sent to the line. teeth,
The character processing unit 130 extracts individual characters from the transmission data transmission block, and before character processing is executed, code conversion is generally performed on the characters in the transmission block on the memory in the communication control device or switching processing device. In many cases, it is executed under the control of a program prepared for that purpose. Alternatively, the character processing section 130 may perform code conversion using a program included in a series of programs for character processing when transmitting and receiving characters with the line controller section 110-i. However, multiple tables for code conversion are prepared and incorporated into the program for this purpose, and at that time, processing for determining which table among the multiple tables should be applied is performed for each code conversion. The program needs to be executed every time, and an increase in the number of program execution steps required for this purpose can, for example, shorten the transfer time of transmitted data within the data exchange and improve the various processing capabilities of the data exchange. In addition to being one of the limiting factors above, performing processing such as identification and addition of transmission control characters in the character processing unit 130 according to the code system of each transmitting and receiving terminal means that multiple different code systems are used. This has the drawback of complicating the hardware or program configuration of the character processing unit 130 when accommodating a terminal to be used.

Furthermore, as shown in Figure 3-A, an additional control field is provided in addition to the character information after code conversion as the contents of the memory of the reception direction code conversion section.
For example, if information indicating that it is a transmission control character (STX/ETX, etc.) is stored in a format convenient for processing in the character processing section, the load of processing received characters on the character processing section will be reduced. As shown in Figure 3-B, an additional control field is provided in the memory contents of the transmission direction code converter, and the transmission character This can be used to exchange information other than the transmission character information necessary for the transfer of the character information, thereby reducing the load of transmission character processing in the character processing section.

As explained above, the present invention provides a communication control device etc. that accommodates a plurality of data communication lines.
A serial-to-parallel converter for transmitted and received data provided corresponding to each communication line, and a character processing unit provided in common for all the communication lines accommodated and which performs data transmission control procedures for those communication lines in a time-sharing manner. By providing a code conversion section corresponding to each communication line between the character processing section of a conventional communication control device, or the parent device for the communication control device such as an exchange processing device or data processing device, This eliminates the need for code conversion processing, which has previously been performed, and therefore has the effect of significantly reducing the load on the processing section or processing device of the communication control system that needs to handle a plurality of different code systems for transmission data.

1 A transmission data serial/parallel converter that accommodates a plurality of data communication lines that transmit data in series, and is provided for each of the lines, and a character processing unit that handles transmitted and received data in character units and controls operations such as data transmission control procedures. In a communication control device that performs data communication, when a transmission/reception character is read and accessed as an address between the serial/parallel conversion section and the character processing section, the character information after code conversion and the transmission/reception of the character are read out and accessed as an address. A code converter including a memory configured to output information including additional information necessary for processing is configured to correspond to the line and is provided for each of the receiving direction and the transmitting direction, and the above-mentioned code conversion section is provided for each transmitting and receiving character. A communication control device equipped with a code conversion function, characterized in that code conversion is performed by accessing memory.
