A docking port on Enterprise (NX-01)
Docking ports are used on a starship to allow the crew access between their ship and another vessel.
The docking ports on board an NX class starship are located on E deck.
In January 2152, a symbiotic lifeform used a docking port to gain access to the Earth Starfleet vessel Enterprise. (ENT: "Vox Sola")
Several years after the final five-year mission of the Constitution-class starship Enterprise, a shuttle docked with the ship following a long tour of the refitted vessel. ("Star Trek: The Motion Picture")
