摘要： A distributed test architecture of transmitting boundary scan Test Access Port (TAP_signals over a serial channel is disclosed. The architecture facilitates the system testing and remote field update of distributed base stations in a wireless network. The distributed test architecture enables system testing as if the distributed units are on a backplane within the same chassis by creating a plurality of logical connections between the distributed unit and the test bus using a single bit fiber line and a five bit TAP test bus.
