OSN 3500 is a new-generation optical transmission system developed by Huawei. It adopts a unified switching architecture and can function as an MPLS/MPLS-TP-based packet device or a TDM device. When working with other devices of Huawei, OSN 3500 supports various networking modes, including the pure packet mode, hybrid networking (packet + TDM) mode, and pure TDM mode, achieving optimal processing for packet services and traditional SDH services. Thus, OSN 3500 efficiently transmits voice and data services over the same platform. Application The SXCSA is a super cross-connect and synchronous timing board. The SXCSA provides service grooming and clock input/output functions in the OptiX OSN system. The cross-connect and synchronous timing board provides the other boards in the system with the timing information, converges and grooms services, communicates with the other boards in the system, and performs the configuration and management functions f...
