You can configure and maintain SLM 1630 on the U2000 Web LCT by following the procedure as follows.
Prerequisites
The nemgr_marine process must be deployed.
SLM 1630 Network Management Process
This topic describes the process for managing the SLM (Submarine Line Monitor) in flow chart form, the process includes deploying a network, managing BUs, managing and monitoring lines.
DCN Management
The U2000 Web LCT communicates with NEs, and manages and maintains network nodes through a DCN. In the DCN, the U2000 Web LCT and NEs are considered as nodes, which are connected by using the Ethernet or DCC physical channels. In practice, the U2000 Web LCT and NEs may be located at different floors of the same building, different buildings or different cities. Hence, U2000 Web LCT and NEs are connected through a DCN, which consists of switches and routers. The DCN between the NEs is referred to as an internal DCN.
Configuring the NE Time
Time consistency between the U2000 Web LCT and NEs is important for troubleshooting and network monitoring. You should set the U2000 Web LCT time and NE time before service configuration.
Configuring Orderwire
You can configure orderwire for NEs by using the U2000 Web LCT.
Configuring Board Parameters
When configuring the submarine cable detection system, you need to configure different boards as required. This topic describes the classification of boards and the methods of configuring board parameters.
Managing Submarine Cable Lines
Submarine cable lines are management objects of the submarine monitoring system. They are also basic units of the line tests.
BU Management
Branching units (BUs) are underwater devices in the submarine cable system. They provide branch routes for fiber transmission and power supply for underwater devices and provide sea earth for branches. When BUs' branches are faulty, you can switch the power supply on the BUs to reconfigure power supply circuit.
Monitoring Submarine Cable Lines
Cost of the submarine communication system mainly covers the submarine equipment such as submarine cables and repeaters. The submarine cables are long and routed in very complicated oceanic environment. Therefore, the cables may be affected by many external factors, such as ships, fishery activities, earthquakes, and military affairs. By monitoring the running status of submarine cable lines in real time, you can locate faults of the submarine equipment such as submarine cables and repeaters in an accurate and fast manner. This ensures the normal transmission of large-capacity transoceanic services. To monitor the working status of submarine cable lines, you can carry out various types of tests in many modes.
Common Maintenance Operations
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.
