[Loop Qualifications & Missing the Demographics]
I have read much talk on both AMTX and WSTL threads regarding loop quals. Noise, bridge taps, distance, DLC systems, and on and on. Talk of 40% or more loops not being loop qualifiable for ADSL.
All this is quite true. However, it needs to be filtered to the demographics to be placed in the proper perspective. When an RBOC rolls out ADSL, the target market has to be looked at. While it may be true that 50% of an RBOCs lines are not loop qualifiable (and I do believe that to be true)the central offices where the rollout is to take place must be taken into account. For example, 60% of the lines in a rural community may not loop qualify, but 85% of lines in a major metropolitan area like New York with short runs probably do qualify.
There are two areas RBOCs will attempt to deploy to: major markets and/or cable modem sites. The two may very well overlap, they typically do. A rollout to a mass density CO cluster in Chicago would be quite different than attempting a rollout in the hills of West Virginia. I do not believe target markets have been taken into account in any of the loop qualification scenarios, nor do I believe it would be easy to properly quantify loop qualification numbers without those markets taken into perspective.
The real threat to WSTL is not loop qualifications, but slow RBOC deployments and other vendors. I may do a short post to try and filter out the vendor marketplace.
