be advised if you are not on a copper pair straight out of the CO you are being feed by something with a battery back up and if your local power goes out and that unit is on the same leg as you which it probably is, its power is going out too and it will be on battery back up which will eventually fail.
If that unit doesn’t feed a muni or hospital forget them dragging a gen out there.
I guess I don’t know how to check this out. Maybe mu download rate is slower now if maybe recently they have substituted the system you described. I’ve had this line for 33 years. In fact, about 8 or 10 years ago the squirrels apparently chewed through the line at the pole, and it had to be replaced. I could see where the line was parted.
