You can configure and maintain RTN (NA) NEs on the U2000 Web LCT by
following the process below.
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 Microwave Links
Before configuring services on a microwave link, you need to configure the microwave link.
Commissioning Networks
Before configuring services for NEs, users need to commission networks for the NEs to communicate with others.
Managing the Optical Power
Optical power management is the core part to ensure normal transmission of signals. For multiplexed signals, sufficient optical power is an important factor to maintain transmission of signals over a long distance. For a single signal, power equalization between signals is an important factor that affects the transmission quality of signals. The U2000 Web LCT provides optical power control, equalization, link detection and protection for link fault.
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.
Numbering Schemes for SDH Timeslots
Two numbering schemes for VC12 timeslots are applicable to SDH optical/electrical lines or SDH microwave links.
