That is one advantage of DSL. You own that whole channel, all the way
back to the fiber backbone so you usually get all you pay for, no
matter how badly your neighbors are pounding the connection. Cable
shares that channel with everyone on your node. (granted a much faster
channel)
Comcast is still running on copper here and once I get to the
distribution box at the end of the street my DSL is fiber. It is all
underground. Comcast is up on the pole suffering the slings and arrows
of outrageous weather.
Both still share that problem that they need to power the distribution
boxes
When I had DSL, seemed as if was dead in the evenings. Figured more than
me were on the channel.
You may not have had enough bandwidth at the distribution box. Sprint
has a fiber backbone to the distribution boxes with plenty of
bandwidth. There was even a rumor that they ran fiber through the
neighborhood but it was never connected to homes. I know that in 2004
when I did a "locate" they marked 3 phone lines in the right of way.
Now days they only mark 2 so it is possible they had a problem with
the fiber when they tried to hook it up and just abandoned it. I hope
it wasn't the royal palm I had out there that killed the fiber ;-)
