Patent ID: 6990095

Claim:
A data switching system for switching data between N 1 input ports and N 2 output ports, comprising: N 1 first input terminals for electric connection to said N 1 input ports, respectively; N 2 first output terminals for electric connection to said N 2 output ports, respectively; M switching matrix planes electrically connected between said N 1 first input terminals and said N 2 first output terminals, and each of which includes: N 3 second input terminals, each of which is electrically connected to at least one of said first input terminals for receiving input data from said first input ports connected thereto through said first input terminals; N 4 second output terminals electrically connected to all of said first output terminals for outputting said input data to one of said N 2 first output ports; N 3 ×N 4 switching elements interconnected as an array including N 4 columns and N 3 rows, said switching elements of a first column of said array being electrically connected to said N 3 second input terminals, respectively, said switching elements of said (N 3 ) th row being electrically connected to said N 4 second output terminals, respectively, and each of said switching elements including: an address correlator electrically connected to one of said N 3 second input terminals for receiving said input data from said first input terminals electrically connected to said one of said N 3 second input terminals, correlating a designated output-port address of said input data with a preset address, and generating a status switching signal according to the correlating result; and a controlled connector electrically connected to said address correlator, switched between a first connection status and a second connection status in response to said status switching signal, and switched to said second connection status to allow said input data to be transmitted to an output port corresponding to said designated output-port; and N 1 /P pre-processors, each of which is electrically connected to P line-cards selected from said N 1 line-cards for determining a connection status for data transmission from said P line-cards.
