Re: What does a CO look like ?
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.

| 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.
