	Ringer equivalence number - Wikipedia, the free encyclopedia
		Note that modern telephone equipment may have a REN significantly lower than 1: as a rough guide, externally-powered digital-ring phones may have a REN as low as 0.2, while modern analog-ring phones (where the ringer is powered from the phone line) typically have a REN around 0.8.
		The total REN for a subscriber's line is simply the sum of the RENs of all devices connected to the line; this number expresses the overall loading effect of the subscriber's equipment on the central office ringing current generator.
		In the United States 1 REN is equivalent to a 6930 Ohm resistor in series with an 8 μF (microFarad) capacitor.
