<..I don't believe it's an issue of the media (fiber or copper)..> It's a function of bandwidth and reliability, and there is a BIG difference between aging copper on one end and fiber/BBFW on the other. <..XDSL is a competitor to wireless fiber and it can come in synchronous flavors..> As you know, xDSL is a generic term for the family of DSL sevices. ADSL is the current widespread telco focus, and as you suggest is not symmetrical. It's also got a LOT of obstacles to widespread deployment and does NOT satisfy even the oneway bandwidth requirements of most enterprises (WinStar's BBFW can offer up to 250Mbps vs ADSL up to ~5Mbs (possibly). HDSL has been used to provision T1s over copper muxable and is incompatible with ADSL in the bundle or through the DLC. VDSL is also asymetrical and requires FTTN, which is YEARS off (also no standards close yet). The other "flavors" of DSL - SDSL, ISDL, Etherloop, etc., are interesting but VERY non-standard and are subject to the same types of implementation and interference obstacles and bandwidth limitations the others have. <....access can be provided over 1 link by 1 company...> Eventually 271 relief will allow the RBOCs to offer single billing as well, and by then, the IXCs and CAPs will also be offering this (probably after purchasing the BBFWs) Bottom line, copper (primarily ADSL) will be used to connect residential customers, fiber will connect about 5% of the commercial buildings (representing about 40% of the business customers) and BBFW will get many of the remaining 700K commercial buildings.
