You can configure and maintain NG WDM equipment on the Web LCT by following the procedure as follows.
Prerequisites
The nemgr_trans process must be deployed.
WDM Network Management Process
The WDM network management process describes the operation tasks of managing a WDM network by using the Web LCT, and the relationships between the operation tasks.
DCN Management
The Web LCT communicates with NEs, and manages and maintains network nodes through a DCN. In the DCN, the Web LCT and NEs are considered as nodes, which are connected by using the Ethernet or DCC physical channels. In practice, the Web LCT and NEs may be located at different floors of the same building, different buildings or different cities. Hence, 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 Web LCT and NEs is important for troubleshooting and network monitoring. You should set the Web LCT time and NE time before service configuration.
Configuring Clocks
A high-quality and stable clock signal is essential to the proper transmission of network-wide data. Before configuring services, configure clocks for boards or NEs. Besides, if you want to transmit clock signals in the same way as the service signals are transmitted (so that the clock signals can serve as timing signals for local NEs), you need to configure the protection for clock signals.
Physical Clock
A stable clock is the basic condition for an NE to function properly. The clock must be configured according to clock configuration principles, to ensure the stability of the clock.
Configuring Board Parameters
When configuring WDM services, you need to configure different boards in the network. The various types of boards and the procedure for configuring the board parameters are described here.
Configuring Optical Cross-Connections
The Web LCT provides the configuration of optical cross-connections. This function realizes cross-connection at the OCh level and grooms services by wavelengths, for future network development.
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.
