Danville, CA | ADSL2+ speed could be up to 25Mbps
According the the ADSL2+ standard, speed could be as high as 25Mbps (under ~3000 ft), 20Mbps (under ~5000 ft), 10Mbps (under ~8K), 6Mbps (~10,000 ft), 4Mbps (~12,000 ft) etc.
So, why only 4-6Mbps? |

Cable can go up to 38 Mbps, but I don't see cable companies offering 38 Mbps (though that probably has a bit to do with the fact that they're overloaded nodes would crumble  ). |

| I thought the driving force for deploying ADSL2+ is Triple Play, i.e., Data, voice & video. The cable companies have all three services and the Telcos only have data and voice.
Maybe they'll announce their broadcast TV, Video-on-demand services later on.... |

With that kind of distance limitation, ADSL2 is useless until we get FTTC. |

The distance charts that are published are very very pessimistic. I work at an independent telco, and have tested 10+Mbps at 14K+ ft out (my house). I have also tested over 1.5mbps at 22Kft out, but I didn't try to test for max speed at this distance. This is a huge upgrade over g.dmt, even though the charts don't necessarily show it. |

FTTC?
I'm on bellsouth's
b@st@rd FTTC network right now, also known as IFITL, and I can't even get >1.5Mbps! 
Oh well!
At least comcast is finally availabe here, and supposedly with 6/768 availabe Q1-2005. If Bellsouth keeps it up like this, I'll be more than happy to relinquish myself to a monopoly I used to loathe, but their network seems to be maturing faster. We just got cable modems here 3 1/2 months ago and already the speed is increasing... Bellsouth should take notice.
