Huawei OptiX PTN 1900 Full Product Description

Product Overview

Key Features

• Carrier‑grade high‑reliability design: Supports 1+1 hot‑backup for main‑control and cross‑connect boards. Rich protection mechanisms include LSP APS, PW APS, ring protection, LAG, IP FRR and VPN FRR to realize fast service recovery within 50ms.
• Multi‑service flexible access: Supports diversified interfaces including E1/IMA, STM‑1, STM‑4 POS, FE, GE and 10GE. Carries E‑Line, E‑LAN, CES circuit emulation, ATM and L3VPN services to adapt to multi‑service convergence demands.
• Precise synchronization capability: Implements 1588v2 PTP and SyncE frequency/time synchronization, meeting strict clock requirements for 2G/3G/4G mobile base‑station backhaul services.
• Complete OAM toolkit: Complies with ITU‑T Y.1731 MPLS‑TP OAM standards, supporting fault detection, performance monitoring and remote diagnosis for end‑to‑end packet transport services.
• Hierarchical QoS scheduling: Supports traffic classification, policing, shaping, multi‑level queue scheduling and congestion management, guaranteeing low‑latency and low‑jitter for real‑time services such as voice and video.
• Unified intelligent O&M: Supports CLI, SNMP and web management, compatible with Huawei iMaster NCE network management system. Supports board hot‑swap for convenient on‑site maintenance.
