1. Universal Switch Architecture for Multiservice Grooming
OptiX OSN equipment uses a universal switch architecture for unified grooming of packet services and TDM services. OptiX OSN equipment can work in packet mode, TDM mode, or dual-domain (packet+TDM) mode.
The three modes can be smoothly switched by upgrading the software of a service board so carriers' requirements on services and networks can be met. The smooth switching between the three modes supports carriers' distributed smooth investment based on the development of the technology and industrial chain.
Based on a universal switch architecture, OptiX OSN equipment uses the packet transmission
technology to perform efficient statistical multiplexing on data services so the transmission cost of every bit is reduced. In addition, OptiX OSN equipment uses the Native technology to transmit TDM services so voice services are transmitted with high quality.
Based on a universal switch architecture, OptiX OSN equipment unifiedly transmits packet services such as 2G, 3G, and VIP private line services so network overlapping is avoided. In addition, OptiX OSN equipment transmits TDM services. Carriers can constitute an end-to-end packet network, dual-domain (packet+SDH) network, or hybrid (MSTP+routers) network that bears L2+L3 services. This complete packet transmission solution allows an evolution from TDM networks to all-IP networks.
2. Hierarchical OAM Facilitating Fault Detection
The Hybrid MSTP equipment supports hierarchical OAM to rapidly detect and locate various faults, thereby improving network reliability. In addition, the Hybrid MSTP equipment supports distributed OAM and centralized OAM.
• Application of Hierarchical OAM
• Distributed OAM and Centralized OAM
Distributed OAM: OAM messages are extracted and processed on service processing boards.
Centralized OAM: OAM messages are extracted from service processing boards and then sent to a cross-connect board for centralized processing.MPLS OAM can be distributed or centralized. MPLS-TP OAM can only be centralized. Before switching MPLS OAM to MPLS-TP OAM, ensure that MPLS OAM is centralized.
3. TP-Assist Solution Facilitating the O&M of Packet Services
Like the SDH equipment, Huawei Hybrid MSTP equipment supports a hierarchical operating & maintenance (O&M) system by using the TP-Assist solution, so packet services can be configured, commissioned, or maintained in an end-to-end manner.
4.Built-In WDM, Flexible Networking
The OptiX OSN equipment uses the built-in WDM technology to transmit several wavelengths over one optical fiber. In this manner, the OptiX OSN equipment can be interconnected with the WDM equipment.
