Narrative:
Cleared via the profile descent runway 33R. We were then given a heading of 280 degrees. Then given direct linng at 7000 ft and 210 KTS. Passing 9000 ft, arrival stated that we had descended below the profile descent and asked us to verify that we were descending via the profile descent. Told him our last instructions were to proceed direct linng at 7000 ft and 210 KTS, asked him if we caused a problem. Stated no, but that we descended into buffalo's airspace. We believed that being vectored off a profile canceled it, and when reclred the controller must specifically tell you if he wants you to resume the profile.

Narrative: CLRED VIA THE PROFILE DSCNT RWY 33R. WE WERE THEN GIVEN A HDG OF 280 DEGS. THEN GIVEN DIRECT LINNG AT 7000 FT AND 210 KTS. PASSING 9000 FT, ARR STATED THAT WE HAD DSNDED BELOW THE PROFILE DSCNT AND ASKED US TO VERIFY THAT WE WERE DSNDING VIA THE PROFILE DSCNT. TOLD HIM OUR LAST INSTRUCTIONS WERE TO PROCEED DIRECT LINNG AT 7000 FT AND 210 KTS, ASKED HIM IF WE CAUSED A PROB. STATED NO, BUT THAT WE DSNDED INTO BUFFALO'S AIRSPACE. WE BELIEVED THAT BEING VECTORED OFF A PROFILE CANCELED IT, AND WHEN RECLRED THE CTLR MUST SPECIFICALLY TELL YOU IF HE WANTS YOU TO RESUME THE PROFILE.
