Subspace link

A subspace link was a type of subspace communication that connected one point directly to another.

In 2369, when a software lifeform known as "Pup" threatened the station, Jadzia Dax tried overloading the stations computers. While attempting this she ordered the opening of subspace links to the New France colony and also to the Nehru colony and the Corado I transmitter array. 

To confirm that Aamin Marritza suffered from Kalla-Nohra Syndrome instead of Pottrik Syndrome, Julian Bashir crosschecked the Bajoran and Federation medical records in 2369. Later, at the request of Constable Odo, Doctor Bashir checked the personal medical history of Aamin Marritza through a subspace link Odo established to Kora II.
