Your description says "Telephone switching room"; in fact, that's a Frame room, and that man looks like a Frame Tech except that he doesn't have a punchdown tool on his belt, so maybe he's just posing. The switching room will be nearby, but this isn't it. Also, color is so important to telephone wiring that you can't get a job as a telephone technician if you are color blind. I find myself looking at the black-and white wires and wondering which ones are blue/white, white/blue, violet/slate, black/brown, and so forth. Each one of those white gizmos (called a "66 block") has 50 wires in 25 pairs, and the wires are identified entirely by their color code. Brian Reid former wirehead
