Not to mention up front install cost. It was literally ten years ago that
I had BRI circuits, but I recall having to BUY the NT-1s at several
hundred bucks a pop. And then install fees for the engineer. It was a
very expensive proposition back then. I imagine times have changed, as it
seems that in some areas it can be actually less expensive than two POTS
lines. I suppose in rural areas where the installed copper is starting to
fail you will get better voice quality, but in the city I don't think you
get much out of it being digital to the house.
