Narrative:

Aircraft was slightly north of course 100 NM southeast when ZID controller asked pilot to verify on the hmv transition for the sweed 6 STAR. Pilot stated 'no, proceeding direct flm.' controller #1 assigned heading 280 degrees for sequence. Aircraft checked on with controller #2 with frequency at FL310. Controller #2 cleared aircraft 'direct dresr, cross dresr at and maintain FL240.' pilot said 'we will need a heading, don't have the equipment for that.' controller #2 assigned 'heading 310 degrees, join the sweed 6 arrival, cross dresr at and maintain FL240.' pilot said 'we don't see dresr on that arrival center.' I assumed the radar position and issued 'fly present heading, intercept the vxv 012 degree radial or 015 degree radial (I'm not certain which) for the sweed 6 arrival, dresr will be 15-20 mi north of your position on the arrival.' pilot, 'so you want us back over on the vxv radial?' me, 'affirmative, it's right off your nose about 2 mi, turn right to join the radial for the sweed 6.' pilot, 'roger.' I asked him to verify in the turn for the radial and he acknowledged 'established.' approximately 8 mi south of dresr, air carrier X mode C showed still level at FL310. I asked if they had started their descent to make the crossing. Pilot, 'we're starting down now...uh, what altitude did you want us at dresr? We must have missed it.' my question was prompted by the presence of traffic 2 mi north of dresr in the adjacent sector in a descent out of FL305 for FL290. I coordinated to have that traffic turned east, then turned air carrier X 30 degrees left (west) and expedited his descent to FL240 separation was lost.

Title: ZID CTLR EXPERIENCED OPERROR AT FL310 AS ACFT IS SLOW IN DSCNT AND CONFLICTS WITH XING TFC.

Narrative: ACFT WAS SLIGHTLY N OF COURSE 100 NM SE WHEN ZID CTLR ASKED PLT TO VERIFY ON THE HMV TRANSITION FOR THE SWEED 6 STAR. PLT STATED 'NO, PROCEEDING DIRECT FLM.' CTLR #1 ASSIGNED HDG 280 DEGS FOR SEQUENCE. ACFT CHKED ON WITH CTLR #2 WITH FREQ AT FL310. CTLR #2 CLRED ACFT 'DIRECT DRESR, CROSS DRESR AT AND MAINTAIN FL240.' PLT SAID 'WE WILL NEED A HDG, DON'T HAVE THE EQUIP FOR THAT.' CTLR #2 ASSIGNED 'HDG 310 DEGS, JOIN THE SWEED 6 ARR, CROSS DRESR AT AND MAINTAIN FL240.' PLT SAID 'WE DON'T SEE DRESR ON THAT ARR CTR.' I ASSUMED THE RADAR POS AND ISSUED 'FLY PRESENT HDG, INTERCEPT THE VXV 012 DEG RADIAL OR 015 DEG RADIAL (I'M NOT CERTAIN WHICH) FOR THE SWEED 6 ARR, DRESR WILL BE 15-20 MI N OF YOUR POS ON THE ARR.' PLT, 'SO YOU WANT US BACK OVER ON THE VXV RADIAL?' ME, 'AFFIRMATIVE, IT'S RIGHT OFF YOUR NOSE ABOUT 2 MI, TURN R TO JOIN THE RADIAL FOR THE SWEED 6.' PLT, 'ROGER.' I ASKED HIM TO VERIFY IN THE TURN FOR THE RADIAL AND HE ACKNOWLEDGED 'ESTABLISHED.' APPROX 8 MI S OF DRESR, ACR X MODE C SHOWED STILL LEVEL AT FL310. I ASKED IF THEY HAD STARTED THEIR DSCNT TO MAKE THE XING. PLT, 'WE'RE STARTING DOWN NOW...UH, WHAT ALT DID YOU WANT US AT DRESR? WE MUST HAVE MISSED IT.' MY QUESTION WAS PROMPTED BY THE PRESENCE OF TFC 2 MI N OF DRESR IN THE ADJACENT SECTOR IN A DSCNT OUT OF FL305 FOR FL290. I COORDINATED TO HAVE THAT TFC TURNED E, THEN TURNED ACR X 30 DEGS L (W) AND EXPEDITED HIS DSCNT TO FL240 SEPARATION WAS LOST.
