摘要：One of important transmission technologies in the broadband ISDN is the synchronous transmission technology based on SDH, which takes NNI (Network Node Interface) as its standard, STM-I frame is formed by the standardized multiplexing procedure of the signals which has the lowest rate required for the optical transmission, and transmitted via a physical medium. The multiplexing principles of SDH follow, using these terms and definitions: Stuffing, Multiplexing, and Aligning
