Abstract
A method and an interface unit is provided to maintain timing synchronization between a first Radio Equipment Controller (REC) and a second REC operating with a multi-standard base station. The first REC receives a synchronization signal and synchronized data output is generated from the synchronization signal. A clock signal is then generated from the synchronized data output. At the second REC, the synchronized data output is received and a synchronization source is then reconstructed from the first clock signal. A timing and frequency component of a second clock signal is then aligned to that of the reconstructed synchronization source, such that the second REC can maintain synchronization with the first REC.
