OTU frame generating apparatus and method

摘要

An overhead data generating unit (100) 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 (100) includes a memory (25) which stores the multiframe structured data corresponding to sequence numbers in each multiframe unit of 256 frames (or the number of frames of 1/2 or 1/4 thereof) from 0 to 255 which are needed for completing a set of meaningful data for each predetermined data item. An editing unit (30) 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 (32), 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 (31).
