Time OAM Automatic Test(China Unicom)

Overview

Communication modes such as TD-SCDMA, TD-LTE, CDMA2000, LTE-A, and MBMS need to synchronize base station air interfaces before working properly. IEEE1588 V2,  the mainstream high precision timing and synchronization protocol, illustrates that synchronization information can be terrestrial transmitted to solve the potential security problems of GPS signals which are difficult to be acquired in application scenarios like in the subway.


OAM synchronization is a useful and necessary function in the operation and maintenance of time synchronized network. In order to validate the OAM function of synchronous devices, we can simulate the fault situation of multiple synchronous OAM functions with the standard technology from China Unicom, and automatically associate the output and input signals to complete the loop automation test. In this case it simulates the faults very fast and easily as well, and improves the test efficiency significantly.
