Abstract
PURPOSE:In a line switching system of the amplification type date highway system where a number of equipments are linked with lines and each equipment receives a signal from an upper line and sends it to a lower line after amplification and waveform shaping, the return to the line of each station shall be conducted through the command from the line in such a manner of the cut off to the line, and the signal line for commanding the return other than the line be deleted.
