摘要：Synchronous transmission technology on SDH is the pointer-based access to the encapsulated payloads in broad band ISDN. The Synchronous Digital Hierarchy (SDH) and the Synchronous Optical NETwork (SONET) are hierarchies used in Europe/South-America and North-America/Japan, respectively. SONET and SDH are based on transmission at rates that are integer multiples of 51.840 Mbps. SONET basic frame structure is a synchronous transport signal level one (STS-l). SDH basic modular signal is called synchronous transport module level one (STM-I). The STM-I rate is an extension of the basic STS-I or also called as STM 0 and operates at 155.52 Mbps, carrying three interleaved STS-l frames[1,2,3].
