I have never done "link" sausage but I did find this ... Looks to be the same as the patties.
Shape ground pork in to patties or 3 to 4 inch links . Cook until lightly browned. Drain. Pack hot sausage into hot jars, leaving 1-inch headspace. Ladle hot broth over sausage, leaving 1-inch headspace. Remove air bubbles. Adjust two-piece caps. Process pints 1 hour and 15 minutes, quarts 1 hour and 30 minutes, at 10 pounds pressure in a steam-pressure canner."
