Narrative:

Air carrier X was nebound to onl and advised he had an RA and was descending to FL360. At that point the data block showed FL367. The nearest aircraft was an air carrier Y at FL350 and 5+ mi, and an air carrier Z at FL370 at the air carrier X 10 O'clock position and 8+ mi nwbound. Conflict alert went off with an air carrier flight at FL350 and 30+ mi. I advised the air carrier X of the area traffic and told it to be level at FL370 in less than 1.5 mins for the air carrier a flight.
