摘　要:同步數(shù)字系列（SDH）是繼準(zhǔn)同步數(shù)字系列（PDH）之后發(fā)展起來的新一代的數(shù)字傳輸體制，它在克服PDH不足，提升傳輸性能的同時也帶來了傳輸效率低下的問題。可否在發(fā)揚優(yōu)勢，既保撐。SDH全部優(yōu)點，同時又彌補不足，提高其傳輸效率，文章中提出的指針式虛容器及其復(fù)用路線以及隨后展開的相關(guān)分析討論，正為求達此目標(biāo)。[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]
