Are you sure the telco is not using fiber-extended line modules? - Not certain. Have you measured the loss from their milliwatt generator? - Yes, results were way off, unless I did it wrong, my gains should be about -2 on a fttp line but the measurements suggest about +7 (The numbers would be very interesting to see since a large number of spa3k and tdm04 users at that distance have significant EC issues.) - I'll post when I get more details...
