Brooklyn, NY | some of them are pretty ugly, from what I have heard. They are rarely as nice as even a moderately well designed computer room. |

Picture the isles in a supermarket, then picture the shelves as plain white/beige boxes with a couple of flashing lights on them. Thats about what you'd be looking at  |

Yup they are covered in wires, and hum loudly from the Telco switchs. The cross connects are large and sometimes confusing! |

Ok here is the only example I could quickly find of some ADSL cross connects:

| I guess what i am asking is... How big are these things? are they like a building or just a little box? The reason i ask is, where i thought it should be i drove by there and all i see is a little tiny box on a pole, no way its a CO ? i live in a very small town, maybe 1000 people. maybe the map cords are off on the mapqwest map or somthing, but thats all i can see from where it says it is on a map, the map from this website. |

Usually, the CO is an actual office. For a carrier that has multiple CO's in an area could have a main one then several smaller ones in an area. The smaller ones could be like an outside closet almost.
Space is limited which is why its hard to be an ILEC and get your DLSAM in with theirs.

They are usually brick or concrete buildings with little or no windows. They are constructed this way so that they can withstand storms, tornados, etc.
They may or may not be marked with the local phone companies name on it.
Here are some i was able to find on Google quickly.

said by Brianv5  :Space is limited which is why its hard to be an ILEC and get your DLSAM in with theirs. I think you mean CLEC. The ILEC (Incumbent) by definition will be the one who built/owns the CO (usually one of the RBOCs).
And, yes, you're right, it usually is quite difficult to colo in a telco central office. The COs emptied out in the 70s, 80s and 90s with the advent of increasingly smaller digital switching hardware and away from the old huge, analog crossbar relay switching, but now they're filling back up with DSLAMs and CLECs and ISPs who want colo space.
On a totally weird tangent, there's a horror/suspense movie (compared to today, it's basically tame suspense) made in the 1970s called "Black Christmas" with Keir Dullea (Dave Bowman from "2001") and Olivia Hussey ("Romeo and Juliet") that has good video of the old crossbar equipment as they show how they manually traced phone calls to the sorority house Hussey lives in. |

| Another good movie is Three Days of the Condor where Robert Redford is in the CO for NYBell. I grew up in CO's due to my father worked for the Telephone Co (Western Electric, then IL Bell). I have been in all but two CO's in Springfield, and still remember the largest one was in Columbus OH. that sat in the middle of nowhere, which now it no longer is, but surrounded by buildings.
A CO is nothing impressive, and really is nothing more then a room filled with racks of equipment, and can cause a Migraine if you stay in the room too long, due to the constant hum from the fans.

If I am not mistaken, that battery plant puts out +24vdc, that is a Lucent rectifier, and by the amount of cable (and lack of fiber) that this is a CO for a mainly residential area or a small town. |

Saint Charles, MO | That is a smaller office. It does have fiber in it, I just don't have any pictures of the fiber equipment. It is part of an OC-192 SONET ring and has several smaller OC-3 rings that feed RT's in the area. |

The COs i've seen (Qwest, Sprint) are basically very nondescript brick buildings with the telco name on them, some large HVAC ports, and little else. In small communities, they might be only one story; in Seattle, they are three or four stories high. |

Typically +24vdc plants are for radio/cellular only. Most landline CO's are -48vdc.
