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>!
