| Main Function Features | Remote Electrical Tilt | Based on AISG2.0 protocol and o-ran-ald.yang model to communication with the external RET equipment |
| Voltage Standing Wave Ratio Detection | Support VSWR detection for each RF port to check antenna connectivity, there are two types of VSWR alarms: Minor VSWR alarm, RU will keep radiating, the service would be degraded. Critical VSWR alarm, RU would shut off corresponding RF branch. |
|
| External Alarm | Support external device supervision, RU would monitor external alarm port state and send notification to O-RU controller based on o-ran-externalio.yang model when input port state is changed (circuit from open to closed or circuit from closed to open). RU can also report external alarm to O-RU controller once input port circuit from open to closed via customized fault. |
|
| Split Mode | Refer to Chapter 5 | |
| PAP | Support PA protection functions, including the scenario: SFP port abnormal disconnect External Power supply abnormal Abnormal signal generated |
