DSL won't work at all over copper at that distance. *You may be 21Kft from
the CO, but you're less than 8K feet from the local RT. *Since most digital

your copper media is in (which you cannot control), and how many other

I'm not sure where you got this information from, but it's incorrect.
Modern DSLAMS work quite well over 20K feet. I spent two years
contracting for AT&T DSLAM engineering, qualifying equipment from
Lucent, IBM & Copper Mountain.

More often than not, the limiting factor is load coils on the lines.
Remember that all this copper was designed to carry voice, and has not
changed much from the original stuff installed over a hundred years
ago. If you can get your local guys to check for load coils and remove
them, you'll likely see an improvement. But you have to ask them
nicely.
