Patent ID: 7304988

Claim:
A Time Division Multiplexing (TDM) cross-connect switching system, comprising: at least one TDM cross-connect switching unit, the TDM cross-connect switching unit including at least one first input operative to receive first input data, at least one second input operative to receive second switched input data, at least one first output operative to provide first output data corresponding to the first input data, and at least one second output operative to provide second switched output data, the TDM cross-connect switching unit further including at least one connection memory configured to store predetermined connection information, a TDM cross-connect configured to receive the first input data and to generate first switched output data based on the predetermined connection information stored in the connection memory, and at least one OR gate configured to receive the second switched input data and the first switched output data, and to generate the second switched output data, wherein the first output of the TDM cross-connect switching unit is connectable to the first input of a conceptually adjacent TDM cross-connect switching unit, and the second output of the TDM cross-connect switching unit is connectable to the second input of a conceptually adjacent TDM cross-connect switching unit.
