Docking ring

The docking ring is the outer circular structure of Deep Space 9 and space stations where starships can dock. The six docking pylons are part of the structure. The docking ring also had cargo bays and mining facilities. (

In 2372, when a peace conference chaired by the Valtusians was held on Deep Space 9, all of the berths on the docking ring were occupied by ships. 

In 2376, the Androssi were making preparations to install quantum torpedo bays on Empok Nor's docking ring.
