The Web LCT is an NE-level management system in an optical transport network. Based on the browser/server architecture, the Web LCT allows you to perform all operations of NE-level configuration and maintenance.
In the telecommunication management network (TMN), the Web LCT is located at the NE layer. That is, the Web LCT is an element management system (EMS) and provides all management functions at the NE layer. See Figure 1.

The Web LCT provides the users with single-layer management network solutions to the transmission networks of up to 32 NEs. The Web LCT accesses a local NE through a LAN or a serial port, and accesses a remote NE through data communications channel (DCC). The Web LCT can be integrated with the U2000.
Data Management
The Web LCT has no NM database, All operations are directly applies to NEs. Hence, the Web LCT does not support the ability to preconfigure an NE, upload and download the NE configuration data, and acknowledge and synchronize alarms.
