Coupling system for a telecommunication exchange installation

摘要

A coupling system for a telecommunication exchange installation is described having a plurality of interconnected binary switching matrices. Each switching matrix has at least two row and two column lines with means for connecting row lines to column lines. A plurality of connection lines form input and output lines for the system of interconnected switching matrix. The interconnection arrangement for the interconnected switching matrices is such that a row line of at least one multiple is connected to a row line of another multiple or a connection line. The other row line of the one switching matrix is connected to a column line of another switching matrix or to a connection line. One column line of the one switching matrix is connected to a column line of another switching matrix or to a connection line. The other column line of the one switching matrix is connected to a row line of another switching matrix or to a connection line.
