Abstract

Abstract:

The SDH technology patches up many deficiencies of the PDH technology. However, the SDH technology is proved to have certain problems when the SDH network is expanding and the number of circuits is increasing. A new technology is a must to patch up the deficiencies of the SDH technology when telecom carriers are confronting fierce competitions and hoping to reduce operation costs, enhance the service reliability and capability of providing differentiated network services, and make their network competitive. Considering the evolution of SDH network and its problems, this paper makes a thorough analysis about rationale, methods, and technical perspectives of using the ASON technology in the SDH network.

Key words: SDH, DXC, VC-4／VC-12, ASON, SLA
