With the time synchronization function, consistency is maintained between the NE time and the U2000 Web LCT server time. In this way, the U2000 Web LCT is able to record the correct time at which alarms occur and the correct time at which the abnormal events are reported by NEs.
When NEs report alarms and abnormal events to the U2000 Web LCT, the time at which such alarms and events occur is based on the NE time. If the NE time is incorrect, then the wrong time with regard to the occurrence of alarms is recorded in the U2000 Web LCT. This may cause trouble in fault location. In addition, the wrong time with regard to the occurrence of abnormal events is recorded in the NE security logs. To ensure the NE time accuracy, the U2000 Web LCT provides one time synchronization scheme: synchronizing with the U2000 Web LCT server.
In this scheme, all NEs use the U2000 Web LCT server time as the standard time. The NE time can be synchronized with the U2000 Web LCT server time manually or automatically. The U2000 Web LCT server time refers to the time of the computer system where the U2000 Web LCT server resides. This scheme features easy operation, and is applicable in networks that require a low accuracy with regard to time.
