Abstract

PURPOSE:To detect immediately the abnormality of a transmission line by comparing a transmitting signal voltage with a pre-set reference voltage and, also, to make it possible to switch a common-use circuit to an emergency-use circuit rapidly and automatically by using this detection signal.
