Narrative:
ZID cleared us from FL280 to FL310 and then handed us off to ZAU. Shortly after checking in with ZAU, we leveled at FL310. Then shortly after that, ZAU told us to turn 80 degrees right and descend immediately to FL280. We asked the reason for this maneuver and the controller replied, 'I don't know what's going on, but ZID should not have climbed you to FL310.' ZAU later told us that ZID had thought they'd given us FL280 as an altitude, not FL310.

Title: AN ACR JET FLT IS ERRONEOUSLY GIVEN FL310 BY CTLR AT ZID. CTLR AT ZAU CORRECTS THE ISSUE WITH A TURN AND DSCNT BACK TO FL280 NEAR BTV, IN.
Narrative: ZID CLRED US FROM FL280 TO FL310 AND THEN HANDED US OFF TO ZAU. SHORTLY AFTER CHKING IN WITH ZAU, WE LEVELED AT FL310. THEN SHORTLY AFTER THAT, ZAU TOLD US TO TURN 80 DEGS R AND DSND IMMEDIATELY TO FL280. WE ASKED THE REASON FOR THIS MANEUVER AND THE CTLR REPLIED, 'I DON'T KNOW WHAT'S GOING ON, BUT ZID SHOULD NOT HAVE CLBED YOU TO FL310.' ZAU LATER TOLD US THAT ZID HAD THOUGHT THEY'D GIVEN US FL280 AS AN ALT, NOT FL310.
