I'm curious to know how you know that exact distance from the CO? That's the kind of thing a nerd like me would love to know in my case. That statistic should actually be referring to the length of the line from the CO to your NID, not the physical distance between those two.

I actually called technical support and asked what my distance from the CO to my NID was and they said the approximate distance was 3,732, this was after they removed a bridge tap that was adding 2,226 feet to my line, yesterday before the bridge tap was removed my line was actually 6,000 ft from the CO, so the bridge tap actually made a great improvement.. They also said some customers in my area were farther than that, some are at10,000 ft but still get U-Verse Internet. The other problem I had called in about was FEC Errors on my line which they said was caused by interference, so they provided me a battery backup for my modem which is a Motorola NVG510 and since then I have had excellent line states. They said that the battery backup conditions the line and eliminates the errors. They also said that anyone with the Motorola NVG510 is suppose to get a battery backup usually...

One way I know how far my CO is from my house is using a web site that shows where the COs are: http://www.marigoldtech.com/lists/co.php If you type into the NPA-NXX your area code for NPA, a dash, and your prefix for NXX you will see your Central Office name. It shows a map of your area and where your CO is located but you can also copy the latitude and longitude and then paste that into Google Earth to get a better more accurate location. You don't have to have the words Latitude or Longitude just the numbers a space and the sign and numbers. In my case, my CO is under a man hole cover about 50 feet further down the street. They are often placed at those left hand turn lanes. The man hole cover would be marked as telephone and not sewer or water. You can use the Google Earth ruler to measure how far your CO is... taking into consideration that it most likely will not be a direct path and you have to, most likely, just follow the streets to that location...ie: corners, etc. I followed my telephone line to the telephone/cable poles all the way to my DSLAM on the sidewalk where I found metal telephone cabinet that was in very bad shape...the back was separated off the cabinet by about an inch as if someone used a crow bar. There is also another, newer one right across the street that I am hoping is the actual DSLAM for my line. For example: There is an Arby's in Seattle which has a telephone number 206-365-xxxx. If I enter 206-365 into the NPA-NXX box it gives me the CO name of STTLWA04. When I click on that, it shows me Central Office Information for STTLWA04 with Latitude and Longitude and a map. Have fun!
Just for clarification, the CO (Central Office) is a large building, with room for the equipment, batteries and other power systems, etc. ... large building.
If anything, what you have under the street is a splice case of some sort that connects to a Remote Terminal (RT). The RT is a way to extend the reach from the CO to the more distant neighborhoods. RTs connect back to the CO over (usually) fiber, then active equipment (like a DSLAM - the thing that feeds your xDSL modem) so the actual "wire distance" starts from the RT, not the CO.
Most likely it would be a splice under the street, to a crossbox or RT, then to a crossbox in your neighborhood and from there to the drop at your home.

I believe they are talking about a "Controlled Environment Vault" (CEV). A CEV is a sealed, air conditioned, powered structure (usually) underground. It has RT equipment, some have U-Verse equipment, batteries, rectifiers ... no Telco switching (ala 5ess switches).
Central Offices are in buildings, as much for physical security as anything else.

"Central offices are now built underground to connect to the underground cables and to contain the electromagnetic radiation thrown off by the plant and to protect the equipment from weather and natural disasters. These facilities are built of concrete, rebar and steel. They are underground bunkers with redundant power, their own environmental systems and massive cable conduit pipes to bring in all the cabling from the entire area. These are all components in the new central offices and telephone operations centers." http://www.inetdaemon.com/tutorials/telecom/pstn/central_office/ It looks pretty clear to me that it is very specifically saying that "Central Offices are now build underground". There are lots of references to "Central Offices being built underground and not located in a "big building". Why are you fighting this concept? In fact, I have actually gone to that man hole cover in the street. It says "Bell Systems" on it. In fact there are a cluster of these located in my very populous area...all under man hole covers...they are all identified as "Central Offices" as per the Marigold web site. Now there may be many other man hole covers that are identified as Bell Systems as well but these specific ones contain "Central Offices".
Central offices may be underground, as in the basement of a large building. But they are most definitely NOT under a manhole cover. The amount and size of switches and other equipment, plus power requirements, plus the sheer volume of cables coming into and out of the central office, plus the personel required to service and maintain all of this require a footprint much larger than what is available under the street. Not to mention security requirements - central offices are an integral part of the nation's communication network and require 24 hour security, something not possible under a manhole cover.
And I wouldn't put too much faith in what the Marigold site tells you about the location of central offices. I looked up mine (and I already know where mine is, I've been there). Marigold placed it in the backyard of a private home about 4 blocks from it's actual location.

AT&T Central Offices are mostly underground. However, UVerse wants to keep all their equipment above ground and there has been controversy...like in Orange County..back in about 2009...where they didn't want UVerse unless they put all their equipment below ground...in the Central Offices, even the RTs, with the rest of the Telco equipment. Orange County didn't want all those ugly Remote Terminal (RT) boxes, that get covered with graffiti , above ground either. Problem was that UVerse equipment, unlike the Telco equipment was more sensitive to extremes...temperature...moisture...etc and would have required the underground Controlled Environment Vaults (CEV), which are very expensive ($40,000-$60,000 each) , and much bigger than the above ground cabinets. The CEV installations would have been much more complicated to install due to sewer and water lines. The Telco Central Offices seem to work just fine underground, and they are there for a reason...partly to dampen electromagnetic noise from interfering with above ground communications, but UVerse would need to keep them above ground to keep costs down and to have more ready access for maintenance, etc. And, of course, increased costs eats into profits. To be competitive with the cable companies, UVerse had to cut costs anywhere they can. http://gadgetress.freedomblogging.com/2009/08/18/att-explains-why-it-cant-build-tv-service-undergrou... http://gadgetress.freedomblogging.com/files/2009/07/undergrounding-facts.pdf
NO, they're not.
You have been horribly misled. Nearly everything you have posted is utterly untrue.
