Narrative:

Approaching dalas intersection on arrival to atlanta, descending through 14000 ft to 13000 ft, TA (TCASII) indicated conflict 5 mi ahead, co-altitude, then +500 ft as we descended. Conflict acquired visually at 3 mi, turned into us and descended. Evasive climbing maneuver by us at 13500 ft (TCASII RA) conflict turned away. We resumed descent to 13000 ft. This event occurred after handoff by ZTL to approach and before check-in with approach. No TA's were given by controllers. Approach advised of climb, no conflicts noted.
