Abstract:
A method and apparatus automatically controls the insertion of information flow data over a shared CPRI link (561) by providing a hardware control mechanism (504-509) at a local radio base station subsystem (501) connected in a CPRI daisy chain configuration between a downstream RE device (570) and an upstream REC device (560) for determining whether the control word being transmitted is sourced from a downstream device (e.g., forwarded data from a downstream RE device) or from the local device.
