Filed: 1981-08-14
Abstract: PURPOSE:To make an error check by allowing the data transfer device at a transmitting station to compare transmitted data with resent and received data without including data for the error check in the transmitted data. CONSTITUTION:The data transfer device of a device DV2 disconnects an input and an output line from each other and sends address information for specifying a device DV3 to an exchange LKE through the output line. The data is transmitted through the input line of the channel CH2 of the exchange LKE and is returned to the DV2 through the output line of the CH2. At the exchange LKE, the presence of the transmitted call from the CH2 to the CH3 is known. The transfer device of the DV2 compares the transmitted data with the received data to make an error check and stops the transmitted call if an error is found. Once the transmitted call arrives, the LKE connects the input line of the CH3 to the output line of the CH2 and sends address information on the DV2 to the output line of the CH3. The address information is read by the DV2, LKE, and DV3 and the DV2 confirms the connection between the DV2 and DV3 by the returning of its address information.
