With the time synchronization function, consistency is maintained between the NE time and the Web LCT server time. In this way, the 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 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 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 Web LCT provides one time synchronization scheme: synchronizing with the Web LCT server.
In this scheme, all NEs use the Web LCT server time as the standard time. The NE time can be synchronized with the Web LCT server time manually or automatically. The Web LCT server time refers to the time of the computer system where the Web LCT server resides. This scheme features easy operation, and is applicable in networks that require a low accuracy with regard to time.
