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.

Sometime they are bigger than that. Around here SBC recently dug and built an
underground bunker filled with many racks of equipment. The only thing above
ground looks like a sheet metal box with fans. It opens to provide stair access to
the equipment below.
These stations are called RCOs (remote communications outlet, or something close
to that). Sometimes "remote terminals". If your DSL circuit terminates at one of
these then the only thing that counts is the length of wire between your home and
the RCO. The RCO would typically multiplex everything onto a high bandwidth fiber
back to the CO. |

That makes sense. I would guess then that RCOs can be "chained" to
extend DSL further from the CO. IOW, an RCO can connect off another
RCO rather than the CO.
Thanks for the info. |
