Turbolift control

Turbolift control was a system aboard Federation starships in the 24th century such as the USS Enterprise (NCC-1701-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. 

In the 23rd century, turbolift elevators could be controlled and regulated by the ship's communications officer.
