Narrative:

Outbnd from perks to hvq on J-6 at FL350 in light chop, requested FL310 because aircraft ahead were reporting FL310 smooth and FL350 choppy. 2 contacts with center requesting FL350. Aircraft ahead also requesting lower. Center had aircraft in front of our flight at FL310. Told to standby. ZID came back, 'descend to FL330, turn right 20 degree or 280 degree heading'. We acknowledged. At the time this was taking place, we were receiving SIGMET reports from ftw dispatch as to the WX in dfw area. Also, F/a came into cockpit saying that they could not make contact with flight deck from rear. PNF (captain) was attempting to read SIGMET and decide whether to request a change in alternate because of WX. Now the F/a returned to cockpit to report they were calling us. From back, first officer requested they push reset button on handset and it will probably fix the problem. With this scenario set, center cleared us to FL330 with right turn 20 degree or 280 degree heading. First officer set heading and altitude window to FL310. Captain read back clearance 20 degree right and FL330. First officer commenced descent out of FL325. Controller asked if we were stopping at FL330. We saw we were below. First officer thought we were to go to FL310. I thought he had set FL330. Descent stopped and climb back to FL330 started immediately.
