The couple times I've called up Verizon to get a DSL setup
running the first question from the support person is have I
installed filters on all existing phones. That's resonable,
It's not running at all? This is usually from some undetected
phone parasite like an alarm system. Otherwise, it just syncs slow.
The next question is how long is my inside patch cable? Huh?
I've just been told that they don't "support" anything
longer than the cable they provide, maybe 15 ft.
Hey, it's their script :) Early exit means low customer
service cost.
So I lie. How can any flimsy patch cord affect the signal
unless we're talking hundreds of feet.
Well, theoretically even 15mm affects the signal. The important
question is: How much? If you're marginal, at 15 kft from the
DSLAM over dubious copper with too many phones, then 15' is probably
all you could handle. That's what they have their script for.
Most likely you're much better than this and can tolerate more.
I'm rock-solid 1.5/378 at 3 kft, and I'd be shocked if 50' of
silver satin would hurt anything on my install.
But installation details matter. The twisting is mostly to reduce
transmitted and received interference. You can approximate the
effect by externally twisting (rolling) the cable a few times
per foot. But if you're running silver satin close and parallel
to power feeds for noisy loads like motors and electronics, I'd
expect trouble.
