Zusammenfassung:	FIELD: electric communications; monitoring busy communication channels without interruption and distortion of data signal transmission. SUBSTANCE: device has on sending end subscriber's line equipment, first space detector, pilot- signal generator, and matching adder; on receiving end, it has receiving line equipment, second space analyzer, zero-fill shift register, inverter, flip-flop, and display unit. Novelty is that it is provided with delay element on sending end as well as pilot-signal receiver and switch on receiving end with relevant connections and other components. EFFECT: improved noise immunity due to eliminating superposition of service signals on data ones and arrival of service signals at receiving subscriber's line equipment. 1 dwge
