Abstract

1,133,644. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 2 May, 1966 [12 May, 1965], No. 19167/66. Heading H4K. A multi-stage cross-point switching network, the cross-points being thyristors, has inhibit gates in the marking leads to cross-point rows of a matrix such that the voltage of a busy link between stages closes the gate associated with that cross-point row connected to that link. A three stage network connecting 50 subscribers to 18 junctors comprises two groups of five 5 x 3 matrices linked to three groups of two 5 x 3 matrices linked to three groups of three 2 x 2 matrices.
