ABSTRACT:
An overhead data generating unit stores and generates the non-multiframe structured data and the multiframe structured data to be inserted into the overhead portion of an OTU frame. The overhead data generating unit includes a memory which stores the multiframe structured data corresponding to sequence numbers in each multiframe unit of 256 frames (or the number of frames of ½ or ¼ thereof) from 0 to 255 which are needed for completing a set of meaningful data for each predetermined data item. An editing unit reads at least the multiframe structured data corresponding to the sequence numbers, and causes to list-display each multiframe in order of the sequence numbers to a display unit, and carries out editing processing in each multiframe unit with respect to the multiframe structured data in accordance with an arbitrary setting by an operating unit.
