Narrative:
When cruising at FL280 we had a TA followed by an RA. Simultaneously we heard center tell an air carrier flight to descend back down to FL270 as there was traffic at FL280. We followed our RA and climbed and notified center of our actions. We climbed approximately 500 ft before clearing traffic (which we saw visually as it passed) and descended back down to FL280. The minimum traffic separation observed on TCASII was 500 ft. After the traffic was clear, we heard center clear them to a higher altitude. There were no further comments made by us or ZJX and I don't think our climb impacted any higher traffic.

Title: MD88 CREW HAD A TCASII RA WITH AN MD80 IN ZJX CLASS A AIRSPACE.
Narrative: WHEN CRUISING AT FL280 WE HAD A TA FOLLOWED BY AN RA. SIMULTANEOUSLY WE HEARD CTR TELL AN ACR FLT TO DSND BACK DOWN TO FL270 AS THERE WAS TFC AT FL280. WE FOLLOWED OUR RA AND CLBED AND NOTIFIED CTR OF OUR ACTIONS. WE CLBED APPROX 500 FT BEFORE CLRING TFC (WHICH WE SAW VISUALLY AS IT PASSED) AND DSNDED BACK DOWN TO FL280. THE MINIMUM TFC SEPARATION OBSERVED ON TCASII WAS 500 FT. AFTER THE TFC WAS CLR, WE HEARD CTR CLR THEM TO A HIGHER ALT. THERE WERE NO FURTHER COMMENTS MADE BY US OR ZJX AND I DON'T THINK OUR CLB IMPACTED ANY HIGHER TFC.
