Key Features
-
Carrier‑grade high‑reliability architecture: Supports 1+1 hot‑backup for main‑control boards, switching fabric boards, fan trays and power modules. Rich protection mechanisms including LSP APS, PW APS, ring protection, LAG, IP FRR and VPN FRR realize 50 ms fast service recovery for mission‑critical bearer services.
-
Massive‑capacity high‑density interface access: Equipped with 32 service processing slots, supports high‑density 40GE/50GE/100GE/200GE/400GE ports, compatible with traditional GE/10GE, POS‑STM‑4 and E1 interfaces, meeting requirements for massive base‑station convergence and huge‑volume private‑line service access华为.
-
High‑precision time‑frequency synchronization: Complies with IEEE 1588v2 PTP and Synchronous Ethernet (SyncE), provides high‑precision clock signal to satisfy strict synchronization requirements for 5G mobile backhaul.
-
Multi‑service bearing & smooth evolution capability: Supports MPLS‑TP, SR‑TP, FlexE, iFIT, L2/L3VPN, E‑Line, E‑LAN and CES circuit emulation services, enabling seamless evolution from legacy PTN to SPN for future mobile bearer networksHuawei Car....
-
Standard‑based comprehensive OAM toolkit: Implements ITU‑T Y.1731 MPLS‑TP OAM, supports end‑to‑end fault detection, performance monitoring, traffic visualization and service‑quality measurement for packet‑transport services.
-
Hierarchical carrier‑grade QoS scheduling: Supports multi‑level traffic classification, policing, shaping and sophisticated queue scheduling, guarantees low‑latency and low‑jitter transmission for real‑time voice, video and core services under heavy‑load conditions.
-
Intelligent unified O&M: Compatible with Huawei iMaster NCE network‑management system, supports SDN‑driven automatic service provisioning, hot‑swappable boards and remote monitoring & maintenance, reduces OPEX for large‑scale metro and backbone transport networks.
