Narrative:
On radar vector 180 degree heading, 15000 ft, with ZTL off rome arrival for a left base runway 8L. Got clearance to descend from 15000 ft to 13000 ft direct dalas. Approximately 14500 ft we got a TA at 1 O'clock position. The first officer slowed the descent as we tried to get a visual. No traffic alert was issued by ATC. We then got an RA which we complied with and climbed to 15500 ft. We picked the traffic up in the climb, opposite direction, and passed under our nose with parachuters exiting the aircraft. I told center we responded to an RA, we were passed to approach and I told them about the RA and was told they were looking into it. Approach and landing was uneventful.

Narrative: ON RADAR VECTOR 180 DEG HDG, 15000 FT, WITH ZTL OFF ROME ARR FOR A L BASE RWY 8L. GOT CLRNC TO DSND FROM 15000 FT TO 13000 FT DIRECT DALAS. APPROX 14500 FT WE GOT A TA AT 1 O'CLOCK POS. THE FO SLOWED THE DSCNT AS WE TRIED TO GET A VISUAL. NO TFC ALERT WAS ISSUED BY ATC. WE THEN GOT AN RA WHICH WE COMPLIED WITH AND CLBED TO 15500 FT. WE PICKED THE TFC UP IN THE CLB, OPPOSITE DIRECTION, AND PASSED UNDER OUR NOSE WITH PARACHUTERS EXITING THE ACFT. I TOLD CTR WE RESPONDED TO AN RA, WE WERE PASSED TO APCH AND I TOLD THEM ABOUT THE RA AND WAS TOLD THEY WERE LOOKING INTO IT. APCH AND LNDG WAS UNEVENTFUL.
