摘要： A communication switching network through which digital signals may be simultaneously transmitted in opposite directions during the same time slot on a single conducting path. The impedances at opposite ends of the path are deliberately mismatched with the result that digital information is transmitted from the low impedance to the high impedance end of the network as voltage changes while the same information may be simultaneously transmitted from the high impedance end to the low impedance end of the network as current changes.

摘要： A cross-point array for telecommunication systems, produced as an xy-matrix in a monolithic substrate with switching means arranged at the cross-points between the x and y conductors in the form of transistors controllable to assume an "on" state with a low impedance and an "off" state with a high impedance, the transistors having their collector-emitter path connected between the x and y conductors and supplied with current from a constant-current generator, is improved by having the collector-base diode of each transistor connected in parallel with a Schottky-diode supplied with current from a second constant-current generator and operating in its forward direction in the "on" state, whereby cross-talk caused by a parasitic transistor function is inhibited between the cross-points in the substrate.
