Key Features
-
Carrier‑grade high‑availability design: Supports 1+1 hot‑backup for main‑control boards, switching fabric boards, fan trays and power modules. Multiple protection mechanisms including LSP APS, PW APS, ring‑network protection, LAG, IP FRR and VPN FRR realize 50 ms fast service recovery for critical bearer services华为企业业....
-
Large‑capacity high‑density interface capability: Equipped with 24 service processing slots, supports high‑density 40GE/50GE/100GE/200GE/400GE ports, and is compatible with traditional GE/10GE, POS‑STM‑4 and E1 interfaces, satisfying massive base‑station convergence and large‑volume private‑line access requirements.
-
High‑precision synchronization performance: Supports IEEE 1588v2 PTP and Synchronous Ethernet (SyncE), provides high‑precision time‑frequency synchronization to meet strict clock requirements for 5G mobile backhaul services.
-
Rich service and 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 PTN to SPN for future mobile bearer networkingHuawei Car....
-
Standard‑compliant comprehensive OAM: Implements ITU‑T Y.1731 MPLS‑TP OAM, supports end‑to‑end fault detection, performance monitoring, visualized traffic and measurable service quality for packet‑transport services.
-
Hierarchical carrier‑grade QoS: Supports multi‑level traffic classification, policing, shaping and sophisticated queue scheduling, guarantees low‑latency and low‑jitter transmission for real‑time and mission‑critical services.
-
Unified intelligent O&M: Compatible with Huawei iMaster NCE network‑management system, supports SDN‑driven automatic service provisioning, hot‑swappable boards and remote monitoring & maintenance, effectively reducing OPEX for large‑scale metropolitan transport networks.
