When I started in IT at the VA hospital I worked in, we had hard wired terminals and the guy that installed most of it was anything but organized. Little was labeled and he didn't follow a color code. Everything was wired directly to the computer room. What a mess. We wanted to move to terminal servers in the computer room, so we built a distribution panel on the wall and connected it to the terminal servers. Then, we built another panel to handle the wires coming from the terminals so we could jumper them to the server panel. Since the guy I was working with was former telephone, we used telephone 110 blocks for the panels. We had to remove each terminal's connection from the multiplexers in the computer room, test them to determine how they were wired, and where they came from. Then came splicing them to cables coming from the distribution panel (this was under the floor) and finally jumper them to their server. These jumpers were standard telephone 4-wire without a sheath, still a bit messy looking, but at least organized. Sure wish I had some pictures, but picture taking was frowned on...
