There may be serious line quality issues, alright. Or when you ask for a dry copper pair, the telco may be dumping a bad line on you to make sure that you can’t do anything that’s vaguely competitive with their own DSL (as limited as that may be).

The telcos drove the CLECs out of business by pulling stunts like that. This is why we are still around: We have been wireless from the beginning. Even before the ’96 Act.

If they’re having problems at 1 mile, then there are serious line quality issues. One mile should be capable of at least 6 Mbps on any normal quality line. I’m at 13,000 feet and I’m pulling a consistent 3 Mbps sync rate.

Some of the loops that are bad are far, far under 20 kilofeet. We had one customer who was a mile away (cable distance, not as the crow flies) who couldn’t sustain more than 1200 Kbps on a single dry pair using any technology. (And we tried several, including G.SHDSL, which is highly tolerant of noise and poor wiring.)

Of course, unless you are the telephone company itself, you might as well give up on using its wires. The FCC has allowed telcos to deny third parties access to its wires and/or charge such exorbitant rates that they can’t provide competitive services. We have had great success with wireless, however.

Brett, what loop length are you at? 20K feet? That would explain most of your problem.

Unfortunately, the quality of the cable plant varies greatly from place to place. Using the best technology that’s commercially available now (and it’s quite good), I can’t get even a symmetrical 2.3 Mbps from many rented loops in my area. So, I’ve gone wireless.

[...] Telephone wire still good for 100 – 300 Mbps The old telephone wire may have several more years of life left in the age of hundred Mbps broadband because Alcatel-Lucent has achieved 300 Mbps performance at distances of 400 meters, and 100 Mbps at 1000 meters. The technology could be commercially available by 2011 and will be a formidable competitor to Cable. [...]

Great News. I can’t wait until I start seeing this in my neighborhood. I might have to shift from Cable to DSL on the fact that DSL now offers a 10mbps connection as opposed to the 3 mbps connection that I have with cable.
