Narrative:
Level at FL240 on descent to cmh. Later, ZID advised lower when clear of traffic, followed quickly by 'descend to FL210, expedite.' I entered FL210 in FCU and hit 'expedite' button. At approximately FL232, ZID asked our altitude. Our response, captain's pull-up and RA followed almost immediately and simultaneously. I never saw the threat. Captain saw an air carrier Y MD80. We leveled momentarily at FL240 and center cleared us to FL190. 1 flight attendant was injured. She went to hospital but was released. Airspace -- traffic in this area is often chaotic. Remotely connected -- cmh ATIS frequency has bleed over and often takes 2-3 cycles to get. Supplemental information from acn 448624: aircraft #1 level FL240, aircraft #2 climbed to FL230. I was working FL230 and below talking to aircraft #1. High altitude controller climbed aircraft #2 and asked me to expedite aircraft #1 down. TCASII activated and pilot reported an near midair collision.

Title: ACR HAS TCASII RA WHEN CTLRS AT ARTCC DO NOT PROVIDE SEPARATION DURING DSCNT. FLT ATTENDANT INJURED DURING EVASIVE MANEUVER.
Narrative: LEVEL AT FL240 ON DSCNT TO CMH. LATER, ZID ADVISED LOWER WHEN CLR OF TFC, FOLLOWED QUICKLY BY 'DSND TO FL210, EXPEDITE.' I ENTERED FL210 IN FCU AND HIT 'EXPEDITE' BUTTON. AT APPROX FL232, ZID ASKED OUR ALT. OUR RESPONSE, CAPT'S PULL-UP AND RA FOLLOWED ALMOST IMMEDIATELY AND SIMULTANEOUSLY. I NEVER SAW THE THREAT. CAPT SAW AN ACR Y MD80. WE LEVELED MOMENTARILY AT FL240 AND CTR CLRED US TO FL190. 1 FLT ATTENDANT WAS INJURED. SHE WENT TO HOSPITAL BUT WAS RELEASED. AIRSPACE -- TFC IN THIS AREA IS OFTEN CHAOTIC. REMOTELY CONNECTED -- CMH ATIS FREQ HAS BLEED OVER AND OFTEN TAKES 2-3 CYCLES TO GET. SUPPLEMENTAL INFO FROM ACN 448624: ACFT #1 LEVEL FL240, ACFT #2 CLBED TO FL230. I WAS WORKING FL230 AND BELOW TALKING TO ACFT #1. HIGH ALT CTLR CLBED ACFT #2 AND ASKED ME TO EXPEDITE ACFT #1 DOWN. TCASII ACTIVATED AND PLT RPTED AN NMAC.
