<Steve sorry about the delay but usually look at SI after dinner and before going to work. > That was nothing compared to mine. The barrage of the last few days has left me somewhat behind, but I DID want to thank you for your insightful and thorough response, ds1. The "juice" (to me) as it relates to ADSL was: <Eight hour for two people. But remember that if the pair is loaded then it probably went more than 18,000 feet so to unload a pair it would take aleast 3 holes to go into so times 3 the eight hours. But if you are going into a splice to unload a pair the engineer will most likely unload more spreading the cost.> You guessed 25% of your lines. Other estimates have been as high as 40%. Let's split it and say 1/3 of US copper have inductance coils that need to be removed. Of course, a great majority would need to be tested to determine which 1/3 HAVE them, so this adds some time. But with 16 man hours per coil times 3 coils per line - you're talking about 50 man-hours. About how many other lines are in the same "dig" such that the cost could be spread? This seems like a pretty costly proposition. And it DOESN'T include fixing bridge taps, or installing the ADSL modem and splitter, and further testing the line. Or the cost of customer support and DSLAM/CO-modem maintenance (and training). We could come up with some ballpark figure, suffice to say that ADSL deployment is DEFINITELY a significant dollar/effort committment and far from a plug and play technology. <Hope this has helped and I hope I didn't get two long winded.> Are you KIDDING? I'm bookmarking your post. Thanks for taking the time, T1 <g>! Steve

ds1: I would also like to thank you for a great post. As it stands now Ameritech will use the Alcatel equipment for it's ADSL deployment. >> but in our area we have been placing CEV's that house the fiber mux equipment in those areas that were more than 10,000 feet from the CO's then rolling back the copper for use closer in. << What is a CEV? This sounds like a Digital Loop Carrier solution. I take it Ameritech uses the Lucent SLC-5 series/SLC-2000 and DSC Litespan units plus others. It seems like a nice migration path to eventually get FTTN.... until later.
