Abstract
A transmission method allowing the reduced amount of hardware in a repeater is disclosed. The overhead portion of a frame is divided into a selected overhead portion for error-correction processing and the non-selected overhead portion for error-correction processing. The non-selected overhead portion such as an overhead for network management can be transferred without error-correction processing, Therefore, a repeater without error-correction processing of the non-selected overhead portion can be used and allows easy insertion and termination resulting in the reduced total amount of hardware in the repeater.
