A circuit architecture is presented to facilitate the remote testing of the collocated transmit and receive circuitry in a base station. The loopback circuitry is inactive during normal base station operation and can be activated when self-testing is required. Both bit error rate (BER) and packet error rate (PER) testing are possible with this cir- cuit architecture.
