To ensure that the transmission equipment can be normally running for long, you need to periodically maintain the transmission equipment or perform some simple operations of troubleshooting on existing problems.
Applying an MML Script to Configure NEs
NEs can be configured in batches by applying an MML script. Configuring NEs in this way boosts the site deployment efficiency.
Maintaining Network Communication on single NEs
If network storms come, NEs become unreachable, or communication is interrupted, users can use the communication diagnosis and maintenance functions (such as loopback configuration) provided for single NEs to troubleshoot faults. The ping and traceroute tests are also supported for monitoring NE communication.
RTN Network Troubleshooting
This topic describes how to troubleshoot the commonly seen faults on RTN network management.
Resetting a Board
You can reset a board by using the U2000 Web LCT. Resetting a board is a maintenance method used in the case of an improper board working status.
Performing a Loopback
The loopback is a common and effective way to locate equipment faults. By using the U2000 Web LCT you can set a loopback for equipment.
Setting Automatic Laser Shutdown
You can enable the automatic laser shutdown function. In the event of a fiber cut, the laser at an optical port is automatically off, to prevent hazardous laser radiation exposure from causing permanent eye damage.
Disabling Service-Affecting Settings Automatically Loopback and laser shutdown are useful NE maintenance functions. Performing these functions may interrupt services at the port and may also interrupt the communication between the NE and the U2000 Web LCT. Hence, you can set automatic disabling before performing loopback or laser shutdown so that the NE automatically cancels the loopback or laser shutdown.
