|  [Availability] Distance Limits?
I got the following distance limits out of AT&T Yahoo faq, Are these the same for Bellsouth?
-----------------
1.5meg
CO = 14kf
RT = 18.5kf
-----------------
3meg
CO = 9kf
RT = 12.5kf
-----------------
6meg
CO = 6.5kf
RT = 8.5kf
-----------------
I believe 3meg gets sold up to 12.5k from CO, and 1.5meg up to 18k and lite up to 24k. I'm I wrong?
Can someone please post current distance limits for speed tiers? |

The differences in distance for service offered by a CO based DSLAM compared to an RT base is interesting. |

Yes I agree it is interesting. But would you believe me when I say that the RT doesn't have a longer loop limit? |

there is no difference whatever in the equipment between the c.o. or the dslam they are exactly the same . the outer limits on adsl are as follows.... 1.5 meg = 24k ft 3 meg = 18k ft 6 meg = 9k ft . Your remote co will not be over 5 k from you if it is near the cross box Various company policies will sometimes limit this to be "on the safe side " All this needless speculation in the absence of real facts! Remember -- 1. cable line distance and real distance are two unrelated measurements . 2 even if the distance is right the line may not be conditioned for adsl. 3 . If it is going to work a human technician has to apply eyeballs, brains and hands , in that order . good luck |

Yep, considering the RT may or may not have the back-haul capability, and may or may not be ADSL2+ capable. ie 6Meg from a Mini-Ram fed by T1's ain't likely to happen at 8.5kft on 26 gauge.
Every distance table I've seen is flawed to some extent. It's not like the service will work perfect at 8,499ft and then it goes to crap at 8,501ft. There are too many variables involved.
But that was the purpose behind Max-Sync anyway. |

Unfortunately your facts are incorrect. As Wayjac says, 1.5 meg is 18kf, 3 meg 13kf. 6 meg I believe is 5.5kf or up to 8kf if your line is ADSL2+ capable.
Will it work at longer distances? Sure, in some cases. But those are the lengths used by the loop qualification system in the former BellSouth region. |

| Ok . Somtimes the c.o. or the remote are setup to be adsl2+ but the preformance of the equipment is not dependent on if it is in the C.O. or not . They are installed randomly . You are quoting loop qualification distances . the distance the company will sell the service to . I am talking about the actual distances that I have provisioned to. On Adsl2+ I have seen 6 meg working at 13k ft . My facts are not incorrect . We are talking about two different sets of related facts in the former Bellsouth region . |

I am at ~7200 ft (direct to CO)... just enough with any line conditions to make 6.0 unreliable and rarely over 4.5 kbs... went back to 3.0 which has always been full speed rock solid reliable.

Yes, that's exactly what I'm talking about. Most customers are going to be held to the qualification limits, so I figure that's what most customers care about. |

More than likely the distance from the C.O. is less because it is normally 26ga cable coming out of the Central Office.From the RT site Is normally 24 to 22 Ga cable feeding the Outside Plant. |

Nope, your info is incorrect. Cable gauge from the RT site towards the customer can be anything from 19 (old rural plant) to 26 gauge. We work on all kinds of whacked loop makeup in trying to get reliable DSL service to our customers. |
