Technology The original 1969 dial-up technology was fairly simple—the local telephone number in Cleveland, for example, was a line connected to a time-division multiplexer that connected via a leased line to a matched multiplexer in Columbus that was connected to a time-sharing host system. In the earliest buildups, each line terminated at a single machine of CompuServe's host service, so that one dialed different telephone numbers to reach different computers.
