Abstract

PURPOSE:To set a call without the occurrence of mismaching on a transmission procedure between data communication devices and without using an additional device such as a call set control device for the data communication device to be stored. CONSTITUTION:A call for transmission of an address signal C of the second data communication device 2 sent from the first data communication device 1 to a repeating device 33 is released temporarily by the repeating device 33. After releasing this call, repeating devices 33 and 34 set a new call between the first and the second data communication devices 1 and 2, and both data communication devices 1 and 2 start transmission of information (a data signal S, a confirmation signal X, etc.) from the first. Consequently, mismatching on transmission control procedures does not occur between data communication devices 1 and 2.
