摘要： PROBLEM TO BE SOLVED: To provide a transponder that makes it easier for a manager to identify a fault location by using the transponder common to a relay device and a terminal station device.SOLUTION: A transponder performs bidirectional conversion between a client side signal and a transmission channel side signal. The transponder includes a client side interface and a transmission channel side interface. Another client side interface or a client device is connectable to the client side interface. A connection determination section determines a connection destination of the client side interface. When a state signal indicating a state of the transmission channel side is inputted to the transmission channel side interface, a transmission signal mode is changed on the basis of a connection determination result.
