Abstract
A method for communicating from a source port (i) to a destination port (j) is employed within a switching system that has m ports, each of the ports being coupled to a local area network via a Hub. The connectivity between the inputs and outputs of the m ports forms a matrix of cross points having m rows and m columns. Each port has a transmit line coupled to a row of the matrix and a receive line coupled to a column of the matrix. A transmission operation from the source port (i) to the destination port (j) involves a first control circuit for unilaterally connecting the port (i) to the port (j), a second control circuit for unilaterally connecting the port (j) to the port (i). The method includes the use of a third control circuit, and a column control bus that couples the third control circuit to a plurality of control circuits including the second control circuit.
