Key Features
-
Carrier‑grade high‑availability design: Supports 1+1 hot‑backup for main‑control, switching fabric boards, fan trays and power modules. Multiple protection schemes including LSP APS, PW APS, ring protection, LAG, IP FRR and VPN FRR realize 50 ms fast service recovery for critical bearer services华为企业业....
-
Ultra‑large bandwidth and abundant high‑speed interfaces: Equipped with 12 service slots, supports high‑density 40GE/50GE/100GE/200GE/400GE ports, compatible with traditional GE/10GE, E1 and POS interfaces, satisfying massive base‑station aggregation and large private‑line service access demands.
-
Advanced synchronization performance: Supports IEEE 1588v2 PTP and Synchronous Ethernet (SyncE), delivers high‑precision time‑frequency synchronization to meet strict clock requirements for 5G mobile backhaul services.
-
Rich service & evolution capability: Supports MPLS‑TP, SR‑TP, FlexE, iFIT, L2/L3VPN, E‑Line, E‑LAN and CES circuit emulation services. Enables smooth 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, traffic visualization and quality measurable for packet transport services华为.
-
Hierarchical carrier‑grade QoS: Multi‑level traffic classification, policing, shaping and queue scheduling, guarantees low‑latency, low‑jitter transmission for real‑time and mission‑critical services.
-
Unified intelligent O&M: Compatible with Huawei iMaster NCE network management system, supports SDN‑based automatic service provisioning, board hot‑swap, remote monitoring and maintenance, reduces OPEX for large‑scale metro transport networks.
