Turbolift control

From Memory Alpha, the free Star Trek reference.

Turbolift control was a system aboard Federation starships in the 24th century such as the USS Enterprise-D that regulated the turbolift elevators on board.

Captain Jean-Luc Picard attempted to contact turbolift control along with main engineering and security when Q transported the bridge crew to an unknown world in 2364, leaving him alone on the main bridge, suspended in time. However, turbolift control did not respond. (TNG: "Hide and Q")

In the 23rd century, turbolift elevators could be controlled and regulated by the ship's communications officer. (TOS: "The Naked Time")
