PROVISION OF STABLE CLOCK INFORMATION

摘要

There is provided a synchronization module for providing stable clock information. The synchronization module receives a high stability clock frequency signal from a first external clock source at least temporarily. The synchronization module receives a master clock signal from a second external clock source at least temporarily. The synchronization module generates a slave clock signal from the high stability clock frequency signal and the master clock signal. The synchronization module provides the slave clock signal to at least one radio base station.
