Abstract
A circuit capable of processing signals of different signal types is provided for identifying the signal type by the signal type setting from an administrator or by the implementation of the optical module, thereby selecting a signal processor to be used. An OTN frame standardized by ITU is used in a fixed manner independent of the signal type to be accommodated, while a corresponding SDH/SONET frame standardized by ITU is used for signal accommodation.
