Abstract: A first transmitting unit provided in a first station transmits a first optical signal to a second receiving unit provided in a second station via an optical transmission line, the first optical signal including first overhead information. A first receiving unit provided in the first station receives a second optical signal transmitted from a second transmitting unit provided in the second station via the optical transmission line, the second optical signal including second overhead information. A first inserting unit inserts first data for detecting line-disconnection troubles into the first overhead information, the data inserting being performed without causing a data amount of the first overhead information to be increased, contents of the first data for detecting line-disconnection troubles being different from contents of second data for detecting line-disconnection troubles being inserted into the second overhead information by a second inserting unit provided in the second station. A first extracting unit extracts the data for detecting line-disconnection troubles from the overhead information included in an optical signal received by the first receiving unit, the data for detecting line-disconnection troubles being either the second data for detecting line-disconnection troubles if the second optical signal has been received by the first receiving unit or the first data for detecting line-disconnection troubles if the first optical signal has been received by the first receiving unit as a result of returning.
