My dad currently has two telephone lines with dial-tone at his place, one is just a line designated for inbound calls from his job, the other is his home phone number along with his lineshare DSL.
He ordered 12mbps IPDSL service on an upgrade promo for his DSL. It was explained to him this would still be lineshare service, and the nature of change in service was describe to him that his broadband would now be fiber-based up to a "node" (which he extrapolated as possibly one of the AT&T boxes you see at various places around his area along the road or whatever), and then would continue to his residence on copper.
Based on that, he and I had a few quetsions about the technology itself:
1) How are his actual telephone conversations now brought to him? Was the node placed at a junction between two (or more) lengths of copper bringing service to a particular neighborhood (or maybe several lengths of copper serving several neighborhoods?), and the data connection switched to lineshare service via moving it off the fiber and to the respective copper that takes it on to the subscriber?
2) If 1 isn't the case, I can't imagine they installed this node and then installed an entirely new copper infrastructure to the area, but maybe so?
3) If 1 and 2 aren't the case, and since obviously no data is coming from the CO, would it mean that his voice conversations now come to the node through the fiber, and then are placed to the copper?
4) In regards to the line without the lineshare, does anything change with regards to how that service reaches his house? Or does it just come from the CO in the same manner it always did?
5) Unrelated to the voice, how does the length of copper from the node to the subscriber affect speed in comparison to regular DSL? If you have a maximum speed of 6mb available, is the loop length the same as 6mb DSL, or does the fact that the data is coming through fiber for part of the transmission somehow result in higher theoretical speeds at any give length?
I'm aware the condition of the copper itself and damage or wear affect the signal quality, but I was more curious about how distances factor in?
