i keep an eye on my exchange for the clean and impacted range for FTTC (as i might be upgrading soon).
i've noticed that the low end impacted has dropped a bit recently. it's now at 63.6 low.
what is "impacted" and what is the reason that the impacted range might drop?
the "clean" range hasn't changed.
in terms of the cabinet, it's about 20 yards away from my house, and the telegraph pole is in my back garden.
