Narrative:
I was serving as first officer on a scheduled flight from mem to cvg. A crossing restriction was given us which the captain wrote down as 'cross 30 mi southwest of cvg at 10000' and 250 KTS.' 10000' was then set on the altitude alerter and the restriction was then read back to ind center. We descended to 10000' and slowed to 250 KTS. At 37 DME southwest cvg we reported (I believe it was cvg approach) 'level at 10000', 250 KTS,' at which time ATC's reply was, 'maintain 10000', your clearance was to 12000'.' this surprised both the captain and I as 10000' was written down, 10000' was set in the altitude alerter and no mention of an altitude error was mentioned by ATC until we had descended all the way down to 10000', leveled off, and were cruising level and switched to cvg approach. I replied that we had 'read back the restriction as cross 30 at 10 and 250 KTS.' we continued on approach control and landed cvg. Supplemental information from acn 90254: both the first officer and I had copied down 10000' and the first officer had read back to ZID, 'cross 30 DME southwest of cincinnati VOR at 10000'.'

Narrative: I WAS SERVING AS F/O ON A SCHEDULED FLT FROM MEM TO CVG. A XING RESTRICTION WAS GIVEN US WHICH THE CAPT WROTE DOWN AS 'CROSS 30 MI SW OF CVG AT 10000' AND 250 KTS.' 10000' WAS THEN SET ON THE ALT ALERTER AND THE RESTRICTION WAS THEN READ BACK TO IND CENTER.
