RTN Network Troubleshooting
This topic describes how to troubleshoot the commonly seen faults on RTN network management.
- Diagnosing Ethernet Protocol Faults
In the case of an Ethernet service fault, you can diagnose the Ethernet protocol and then restart the protocol state machine by restoring the protocol, to remove the protocol faults.
- Scanning ODU Frequency Interference
This topic describes how to use the U2000 Web LCT for frequency scanning. When channel interference occurs, the commonly-used method is using special instruments to check whether interference occurs on transmit frequencies. However, using special instruments to scan frequencies is not cost-effective. Instead, you can use the automatic frequency scanning function provided by the U2000 Web LCT.
- Turning On or Off a Laser
You can turn off or turn on a laser when necessary. For example, if an optical port does not carry services, you can turn off the laser to prevent hazardous laser radiation exposure from causing permanent eye damage. You can turn on the laser when the optical port needs to carry services.
