I'm confused about how the ADSL distance works. I've read of different distance limitations ranging from 6000 to 18000 feet depending on service provider, lines, etc.
Most of what I've read indicates that the distance limitation is measured from the "central office". What is that? Is it the building located in various neighborhoods or small towns that service the area within several miles?
If so, how do these "small stations" (about the size of two large home refrigerators) that are installed on small concrete pads when DSL is brought to a specific bunch of homes, affect the distance limitation? What is the function of these "small stations"? What are they called?
Thanks for any information.
