We didn't always use terminal servers in college. There was a cluster of 3B2s, and two were accessible to students from the terminal room. There were probably 40-50 terminals in the room, and I believe they were each hardwired to either "earth" or "wind". I don't know about the connectors or cabling which achieved that, because the servers were located on another floor of the building. But we were definitely hardwired in. The rest of the university had general-purpose terminal rooms that used port concentrators. These had a rudimentary CLI that enabled the user to specify a resource to connect to, so it was sort of a circuit-switch deal. Among the resources were VAXen running BSD, VMS machines, and Annex boxes which could be used for TCP/IP connections across campus, or to the outside world. These Annex boxes were also frontends for dial-up users coming in over modems.
