Here are the requested pics. First, the entire box (I know, it ain't pretty):
Then, the inside of the "NID".
The green pair is the new U-verse DSL connection (a technician showed up the day of the activation and swapped the orange pair for the green pair). The red pair is the wire to the second phone line in the house.
Notice the two screws holding the box to the back panel. The AT&T installed put in only one. Obviously, the box isn't going to be stable with only one screw.
