摘要： There is disclosed a conversion circuit arrangement for switching digital data signals between data terminals operating with different data transmission procedures. The circuit arrangement adapted for use with an electronic data switching system is composed of at least two interface circuits having input/output converting networks. External terminals of these interface circuits are connected to respective input/output means of the switching system for each type of data terminal. Internal input/output terminals of the interface circuits are connected to respective terminals of a storage unit. There is provided a control unit for controlling data transmission between the interface circuits and the storage unit and vice versa such that messages are buffered in the storage unit. The stored message is converted according to the data transmission procedure of the receiving data terminal.
