ABSTRACT:
A method and apparatus for synchronous frame communication first communicates a frame signal having communication data and first control information having a bit length and an SDH frame structure in a part of frame time interval and a control information processing method based on an SDH-frame-overhead-process for processing the first control information that includes bytes indicative of each of a relay node's section overhead, an end terminal section overhead, and at least a part of a byte of higher path's overhead. In the frame time interval a signal is communicated by a different second communicating method having the communication data and second control information having a bit length capable of including a significantly higher amount of information than that of the first control information and which corresponds to the first control information byte communicated in the frame time interval.
