I am not arguing :3
I do not know the american way of measuring kilometres or how to convert it so bear that in mind.
Jack, I shall explain how the Aussie ISP's do it if you in return explain how the Americanos do it :)
(Copper example)
Here, you have a house, say my house.
H
then, you have a lead in from the house to a pit in your street, say 2-4 houses a pit sometimes more depending on where that person lives.
H --> P
Now the copper from those houses all meets up at the pit and then goes from the pit to the exchange. My house is not on a RIM between myself and the exchange. A tool we use at work called SSS Cable Checker (about 10% of you thought "ahhhh" when I just wrote SSS) says I have got about 1600m of copper from my house to exchange. I sync at about 1600kbps which is way over the AU Average for ADSL2+.
Copper follows the road, you could be across the street from an exchange and the cables might go through 5 streets before they get to you. Even worse you could be one of the people living at "67 St Leonards Boulevard, Dayton, Western Australia" on the NBN Rollout Map.
So now we add the exchange:
H --> P --> E
Other people arn't as lucky and live in places on RIM's or have lots of pillers on their lines. RIM's arn't super bad though, as they have a fibre backbone to the exchange and if you are on a tophatted (older) RIM or a newer rim, its like being 500m from an exchange but you risk congestion.
H --> P --> R --> E
Then DLSAM's come into play at the exchange and if I have to explain them to you my head will explode. Here is a WIKIPEDIA ARTICLE. Basically they allow you to get ADSL2+ and they are freakin' expensive.
THEN THERES THE PoP. THATS TOP SECRET.
