Abstract
It is efficient to detect a data error, which is produced in a packet switching network, in a range between final users of data. A packet including data for detecting a data error is formed for a data unit made up of a series of data packets sent to a packet mode terminal, and send to the packet mode terminal. A data error is detected by the data for detecting a data error each time the above-mentioned series of data packets are received.
