Questions and answers
how to unmuted ODU in ZTE System
To unmute the ODU in the ZTE ZXMW NR8250 system, follow these steps:
1. Check if the ODU is in mute mode due to a failure (e.g., ODU or RMU failure).
2. If the ODU is muted due to a failure, resolve the issue by replacing or repairing the faulty component.
3. If the ODU is manually disabled, enable it through the system interface.
4. Ensure that the switchover conditions are met, as the system automatically selects the active ODU based on priority rules.
If the ODU remains muted, verify the configuration and alarms for any issues preventing activation.
