Narrative:
Cleared to 11000 ft and to hirst and rest of arrival. Noticed that we would be higher than 11000 ft at hirst. Mentioned to the captain, pilot at the controls. Continued descent to 11000 ft. Complied with speed on STAR. Communication with ATC and remainder of flight uneventful. May have been just cleared to 11000 ft and not hirst at 11000 ft. PF programmed CDU with altitude and speeds. Supplemental information from acn 365051: I started descent upon receiving clearance. I selected descent page and saw I had plenty of room. Unfortunately I had typed 210 speed restr in the altitude field instead of the speed field. This resulted in being high at hirst but on speed. When the first officer brought this to my attention I expedited the descent.

Title: PIC OF B757, PF, MISPROGRAMS THE FMC. HE PLACES THE 210 KTS SPD RESTR IN THE ALT FIELD OF THE FMC INSTEAD OF THE SPD FIELD. ACFT CROSSES INTXN FIX HIGHER THAN CLRED.
Narrative: CLRED TO 11000 FT AND TO HIRST AND REST OF ARR. NOTICED THAT WE WOULD BE HIGHER THAN 11000 FT AT HIRST. MENTIONED TO THE CAPT, PLT AT THE CTLS. CONTINUED DSCNT TO 11000 FT. COMPLIED WITH SPD ON STAR. COM WITH ATC AND REMAINDER OF FLT UNEVENTFUL. MAY HAVE BEEN JUST CLRED TO 11000 FT AND NOT HIRST AT 11000 FT. PF PROGRAMMED CDU WITH ALT AND SPDS. SUPPLEMENTAL INFO FROM ACN 365051: I STARTED DSCNT UPON RECEIVING CLRNC. I SELECTED DSCNT PAGE AND SAW I HAD PLENTY OF ROOM. UNFORTUNATELY I HAD TYPED 210 SPD RESTR IN THE ALT FIELD INSTEAD OF THE SPD FIELD. THIS RESULTED IN BEING HIGH AT HIRST BUT ON SPD. WHEN THE FO BROUGHT THIS TO MY ATTN I EXPEDITED THE DSCNT.
