ABSTRACT:
A switching system, specifically useful as a telephone central switching system, to establish a number of simultaneous but independent communication links between selected lines, comprising: (1) a CRT to transmit signals in the form of modulated light beams, (2) lenses to focus and direct the light generated, (3) an array of photosensors each connected to a different communication line, and (4) electronic controls to direct the beam as required. Also disclosed are electronic embodiments of the foregoing; time division multiplex and composite systems to expand the basic system; and also arrangements to facilitate adaptation of the system to telephone applications. The system avoids much of the hardware and circuit complications of prior switching systems.
