MAGIC SDC provides seamless switching of redundant DAB multiplexer systems. System can be used as classic ETI switch for E1 G.703/G.704 lines or optionally as EDI switch for IP networks. MAGIC SDC monitors output signal of each DAB multiplexer permanently. If an error is detected in multiplex, system switches automatically to other input. In parallel time stamp in output signal of switch can be re-generated, so that continuous time stamp is guaranteed to arrive at transmitter. To minimize required input buffering, frame counter (CIF) of ETI output signal can be replaced additionally. Switching criteria and switching behaviour (mono stable, bi-stable) can be configured by user.
