摘　要:同步数字系列（SDH）是继准同步数字系列（PDH）之后发展起来的新一代的数字传输体制，它在克服PDH不足，提升传输性能的同时也带来了传输效率低下的问题。可否在发扬优势，既保撑。SDH全部优点，同时又弥补不足，提高其传输效率，文章中提出的指针式虚容器及其复用路线以及随后展开的相关分析讨论，正为求达此目标。[著者文摘]

The research of multiplexing and,transmission efficiency of SDHGAO Feng-ge Suzhou University of Science and Technology, Suzhou Jiangsu 215011,ChinaAbstract:The synchronous digital hierarchy （SDH） is a new generation digital transmission system which develops after the plesiochronous digital hierarchy （PDH）, it brought the issue of transmission efficiency lowly while overcame PDH＇s shortage and upgraded transmission performance. Could compensates for insufficiency while carry forward the superiority, that is raises transmission efficiency while maintains all merit of the SDH？ This paper proposes a concept of pointer-virtual container and multiplexing as well as relevant analysis discusses are in order to achieve that goal.[著者文摘]
