Abstract

Improvements in telephone switching systems comprising a number of groups of intersection point matrices, said groups being cascaded to extend from input terminals on an input side to output terminals on an output side of said system, circuitry operable in response to dialing signals applied to selected ones of said input and output terminals, for selecting a circuit available through said system, said circuit selecting means comprising nodes representing each of said matrices with upper nodes representing matrices connected to input terminals and lower nodes representing arrays not connected to input terminals, means in said circuit selecting means actuated in response to said dialing signals to mark all available ones of the nodes in the circuits between said marked input and All output terminals dis wearable and control means for sequentially selecting and identifying a particular of said nodes commenting with the selected lower node connected to said marked output terminal and ending with the upper node connected to said marked input terminal, to select an analog circuit through said matrices of points of intersection.
