Abstract

PURPOSE:To make folding test even for two-wire transmission line, by transmitting a test data with a time difference through folding and comparing the transmitted data and a returned data. CONSTITUTION:When a transmission data is transmitted via a transmission line from a master station A to a slave station B, the transmitted data is once stored in a storage device at a reception side B and the stored data is transmitted via the transmission line 3. The presence/absence of errors can be confirmed at the transmission side A by comparing the returned data with the transmitted data.
