I need some help from TELECOM readers. There's a suggestion for modifying our project's wiring scheme which would result in tip and ring being reversed for some number of outlets within a house (residential, single-pair, POTS usage). What kind of problems will this polarity reversal cause? I've heard that a standard, old electromechanical phone won't have any trouble, but what about answering machines, modems, and other devices? My intuition is that it will be a problem, but I'm just a software person - what do I know? :-) Thanks for any help! -- John Owens john@jetson.UPMA.MD.US uunet!jetson!john +1 301 249 6000 john%jetson.uucp@uunet.uu.net
