AbolishedFrame structure for synchronous digital hierarchy signal
同步数字体系信号的帧结构
Application Summary AI generated
This standard specifies the frame structure for Synchronous Digital Hierarchy (SDH) signals, defining the byte-by-byte organization of overhead, pointers, and payload within the STM-N frames. It is applied in the design, testing, and interconnection of SDH transmission equipment, such as optical line terminals and add-drop multiplexers, used in public telecommunications networks. The standard ensures consistent signal formatting for multiplexing, cross-connection, and transport of digital data across fiber-optic backbone networks.
