Abstract
A method for switching digital signals is disclosed. From an external control connection, the method configures a plurality of digital signal paths with at least one crossbar switch and controls a plurality of input and output connections for the digital signals based on the crossbar switch configuration. The method further involves automatically revising the digital signal routing without manual intervention based on configuration commands from the external control connection.
