RECEPTION DEVICE, TRANSMISSION DEVICE, OPTICAL TRANSMISSION DEVICE, OPTICAL TRANSMISSION SYSTEM, AND MONITORING METHOD

摘要

A reception device has a receiving unit, an extracting unit and an outputting part. The receiving unit receives a lane signal transmitted through each of a plurality of lanes from a transmission device that partitions an OTU frame into a plurality of the lane signal. For each of the plurality of lanes, the extracting unit extracts, from the lane signal received by the receiving unit, data included in an overhead of an OTU frame. The outputting part outputs, as information indicating communication conditions of the lanes transmitting the lane signal from which the data is extracted by the extracting unit, information relating to the data extracted by the extracting unit.
