Abstract
PURPOSE: To make it possible that control signals are inserted in a fixed frequency band of the descending direction started from the head end, and the signals are detected at two-ways line amplifier, and the amplifier of ascending direction is inserted in the main line and the ascending circuit is automatically connected, so that grouped noises can be minimized by using a simple circuit composition.
