本文介绍线形、环形、星形和网孔形等四种常用的SDH网拓朴结构。文中还阐明了OLTE、ADM、DXC等三种基本SDH网络单元的功能和SDH同步帧结构。最后讨论了PDH向SDH过渡的方式。
This paper presents four kinds of common SDH network topological structures
i. e. linear
ring
star and meshed. Functions of three kinds of basic network elements (OLTE
ADM
DXC) and SDH synchronous frame structure are explained. Finally
transition mode from PDH to SDH is discussed.
