Telco's want every customer served by the same interface -- no exceptions for those pesky FTTH resellers (who'd really prefer a straight OC12 backbone feed from the telco, no DSL) So, I definitely see the sillyness -- but also the opportunity for FTTH -- in spite of DSL. -- Remember the future.

dslwanter It's coming Premium join:2002-12-16 Niles, OH Reviews: ·AT&T Midwest 1 edit	DSL isn't feasible over fiber, period. DSL is a radio signal that dies after 3 miles. If it was easy to repeat, telco's would be able to offer 6mbps DSL to their entire blueprint. The signal would be more reliable over fiber since fiber is virtually transparent to EMI unlike copper. Verizon has the right idea, so do cable companies offering DOCSIS via FTTH in new areas. AT&T is on the wrong track and will still have to deal with "distance" issues. Why? Because they won't ditch xDSL technology. If a company is going to spend the money to build a fiber network, they're going to look to save on ways to provide service and DSL wouldn't be a smart choice. -- Check our my internet radio station: »www.thebomb102.com, featuring new music and hits of the millennium, powered by FTTH!

DSL is a radio signal Your cell phone antenna output would happily modulate a media converter (connected via coax). It is analog modulation with digital encoding -- and for VDSL it contains 256 "discreet multi-tones" (oh they're very discreet ) I still see no technical reason -- but yes, apparently no telco will spend ~$200 per customer to extend a DS-1 line via media converters. -- Remember the future.
