Narrative:
ZID issued us descent clearance from FL390 to FL350. I started descent at 500 FPM. At approximately FL380, ZID wanted us level at FL350 in 2 1/2 mins. I increased descent to 1500 FPM and was vectored around air carrier Y traffic. I leveled at FL350, never saw air carrier Y on the TCASII, and was told to call the center. I did call, center said we took 5 mins to descend to FL350. I complied with all the ZID instructions.
