O1 Interface
O-RAN O1 Operations and Maintenance Interface
Management interface connecting all O-RAN components (O-CU, O-DU, O-RU, Near-RT RIC) to the SMO.
Technical Explanation
The O1 interface provides standard Operations and Maintenance (O&M) functions: configuration management (via NETCONF/YANG), fault reporting, performance monitoring, and software management. It enables vendor-agnostic network management from a single pane of glass.
Key Functions
- Standardizes FCAPS management across all O-RAN network components
- Utilizes NETCONF / YANG data models for automated configuration
- Streams real-time performance alarms and KPI counters into the SMO
