| Abstract: | This paper introduces the application of SDH in the access network and subscriber loop, compares the features and advantages/disadvantages between SDH and traditional PDH, and describes the SDH network configuration and equipment application, analyses and describes the strategies and approaches of SDH evolution in the access network, including the evolution of network management. Finally, some examples of SDH application in the access network are given, including NTT's SDH local area service node and UK's integrated CATV/SDH network. |
