A data inspection method includes the steps of (a) writing original test data in a memory region, (b) reading the test data from the memory region, and (c) comparing the read test data with the original test data, so as to make a data inspection. The test data is formed by a plurality of cell data. Each of the cell data includes a delimiter indicating a boundary between two adjacent cell data, a cell number indicating an order within the test data, a cell data length indicating a data length of the cell data, and pattern data. Each of the cell data in the test data has a cell data length which is variable.

Data inspection method and apparatus

In a repeating unit testing system, a first tester includes first packet transmission means for transmitting a plurality of packets, whose transmission destination address is a second repeating unit, to a first repeating unit for a fixed period of time, and line connection-disconnection log information collection means for collecting log information regarding connection and disconnection of a line from the first or second repeating unit. The first repeating unit includes line connection-disconnection means for connecting a line to a second communication network or disconnecting the line if transmission of packets is not received for more than a fixed period of time, and second packet transmission means for receiving the packets and transmitting the packets to a third port. Further, the first or second repeating unit includes line connection-disconnection log information acquisition means for acquiring log information, and line connection-disconnection log information transmission means for transmitting the log information to the first tester.
