OptiX OSN equipment adopts "unified switching" architecture to realize unified scheduling of packet services and TDM services, and builds flexible application modes: pure packet mode, pure TDM mode and hybrid mode (packet + TDM).

The three modes can be expanded through the service board level to realize smooth conversion, so that the most suitable mode is always used to meet the demands of operators' service and network development, and it is convenient for operators to follow the technological development and industrial chain maturity to make step-by-step smooth investment.

Based on the "Unified Switching" architecture, OptiX OSN equipment adopts packet transmission technology to realize efficient statistical multiplexing of data services and effectively reduce the transmission cost of each bit of service; at the same time, it inherits the advantages of SDH and provides Native bearer for TDM services, effectively ensuring high-quality voice service transmission.

The architecture of OptiX OSN equipment is shown in Figure 1.

Based on the "Unified Switching" architecture, OptiX OSN equipment, as a packet transport product compatible with TDM services, can realize the unified bearing of 2G, 3G, and private lines for large customers and reduce network overlapping. Operators can set up end-to-end packet networks, hybrid networks of packet and SDH, or co-locate with routers to realize unified L2+L3 bearer, building a complete packet transport solution and realizing the harmonious evolution of bearer networks from TDM to ALL-IP.
