I don't think the FTTN strategy was necessarily a bad idea, but they needed to put nodes closer to homes. With closer nodes at 50-100mbps, the product would have so much more longevity. It just wasn't smart to bet on "uncooked" technology. By the time something comes along to improve on VDSL, it's going to be needed to match the competition. [/BQUOTE :

Why did AT&T go with FTTN vs. FTTH, IMHO it was strictly cost. Now the question is in the long run will it really be a cost savings to AT&T? How much more will it cost to go back and retrofit the VRad's for pair bonding? How much more will it cost for extra hardware at the home? What about where there isn't an extra pair of copper availble in tne existing infratstucture, how much more to install some? How much more to install more VRad's to reduce the distance to get the faster speeds? How much more for the maintance and electrical costs for those VRad's? Even then, after spending all these dollars to get to what, 4 concurrent HD streams of TV will that be enough to support what consumers want? HDTV penatration rates are going up and between moew HD sets in the homes and HD DVR's IMHO 4 streams won't be able to handle demand in a few years.
