The wide blocks with 6 posts across are for CPE.
All the customer wires should be punched down on them once and never touched again unless there was a problem on the block itself.
The LEC leaves jumpers with a tag on them, or terminates onto a special 66 block with a LEC cover on it.
This arrangement is almost never followed, lots of LEC techs dont know how to 66 block, and I swear even more customer techs dont know either.
The big black cable on the left going to blocks makes me think this is a big east coast city. The midwest and west coast are way too uptight about lightning/high voltage to allow unprotected pairs like that.
