Narrative:
Air carrier X at FL330 eastbound and air carrier Y sbound. Third aircraft 25 mi behind air carrier X. I determined air carrier X and air carrier Y were in conflict. I told my 'D' side to coordinate FL290 for air carrier X and turn air carrier Z 15 degrees left. I immediately coordinated with the sector underlying my airspace and got approval for FL290. I then called the csv sector in ZTL and got approval for FL290. When off the line I heard my 'D' side telling mem to turn air carrier Z, logically air carrier X should have been approved. I descended air carrier X to FL290 and requested he expedite per ZTL's request. All 3 aircraft at FL330.

Title: D-SIDE ARTCC CTLR AT ZID COORD TFC TURN WITH MEM ARTCC BUT, APPARENTLY DID NOT COORDINATE A DSCNT REQUESTED BY THE RADAR CTLR.
Narrative: ACR X AT FL330 EBOUND AND ACR Y SBOUND. THIRD ACFT 25 MI BEHIND ACR X. I DETERMINED ACR X AND ACR Y WERE IN CONFLICT. I TOLD MY 'D' SIDE TO COORDINATE FL290 FOR ACR X AND TURN ACR Z 15 DEGS L. I IMMEDIATELY COORDINATED WITH THE SECTOR UNDERLYING MY AIRSPACE AND GOT APPROVAL FOR FL290. I THEN CALLED THE CSV SECTOR IN ZTL AND GOT APPROVAL FOR FL290. WHEN OFF THE LINE I HEARD MY 'D' SIDE TELLING MEM TO TURN ACR Z, LOGICALLY ACR X SHOULD HAVE BEEN APPROVED. I DSNDED ACR X TO FL290 AND REQUESTED HE EXPEDITE PER ZTL'S REQUEST. ALL 3 ACFT AT FL330.
