BILATERAL ELECTRICAL COMMUNICATION SWITCHING NETWORK

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.
