Telco Fiasco

This is a DSX panel. It carries the T1 signal to and from the site. It's mounted inside the telco cabinet. It's one of the things I have to do in conjunction with the Ultra swap-outs. The thing to the left is the 66 Block. There are a bunch of colored wires going into it. Now, other than knowing what color wires go where, I have no idea what these things do. No clue at all. All I know is that it's stuffed inside a little tiny cabinet that you have to bend over and stuff yourself into just to get to it. It's a little disheartening taking so long to do something so uncomfortable when you haven't the foggiest idea how it all works.
