Narrative:

From an altitude of 2000 ft, and approximately 13 mi southwest of teterboro, we were cleared to ny approach for the ILS runway 6 approach, circle to land on runway 1. It was mandatory to cross dandy (6.4 DME teb) at 1500 ft MSL. I missed this requirement in reviewing the approach, electing to maintain 2000 ft until GS intercept. In doing so, we crossed dandy above the mandatory altitude of 1500 ft (estimating 1800 ft). On short final, teterboro tower stated that ny approach had called them, requesting they point this out to us. They stated that we had been instructed to cross dandy at 1500 ft. Neither I nor the first officer can recall if approach had cleared us in this manner. However, the approach plate clearly states that 1500 ft is mandatory upon reaching dandy. I believe the primary contributing factor to this incident was my failure to thoroughly brief the approach. Conditions were clear, with unlimited visibility. Consequently, my approach briefing with the first officer included all the usual items for a VFR approach, but not the ILS procedures. Had I done so, we would have observed the crossing requirement, thus complying after receiving the approach clearance, even if ATC had neglected to instruct us to do so.

Title: A FALCON 20 FLC REMAINED ABOVE A MANDATORY XING ALT ON APCH TO TET.

Narrative: FROM AN ALT OF 2000 FT, AND APPROX 13 MI SW OF TETERBORO, WE WERE CLRED TO NY APCH FOR THE ILS RWY 6 APCH, CIRCLE TO LAND ON RWY 1. IT WAS MANDATORY TO CROSS DANDY (6.4 DME TEB) AT 1500 FT MSL. I MISSED THIS REQUIREMENT IN REVIEWING THE APCH, ELECTING TO MAINTAIN 2000 FT UNTIL GS INTERCEPT. IN DOING SO, WE CROSSED DANDY ABOVE THE MANDATORY ALT OF 1500 FT (ESTIMATING 1800 FT). ON SHORT FINAL, TETERBORO TWR STATED THAT NY APCH HAD CALLED THEM, REQUESTING THEY POINT THIS OUT TO US. THEY STATED THAT WE HAD BEEN INSTRUCTED TO CROSS DANDY AT 1500 FT. NEITHER I NOR THE FO CAN RECALL IF APCH HAD CLRED US IN THIS MANNER. HOWEVER, THE APCH PLATE CLRLY STATES THAT 1500 FT IS MANDATORY UPON REACHING DANDY. I BELIEVE THE PRIMARY CONTRIBUTING FACTOR TO THIS INCIDENT WAS MY FAILURE TO THOROUGHLY BRIEF THE APCH. CONDITIONS WERE CLR, WITH UNLIMITED VISIBILITY. CONSEQUENTLY, MY APCH BRIEFING WITH THE FO INCLUDED ALL THE USUAL ITEMS FOR A VFR APCH, BUT NOT THE ILS PROCS. HAD I DONE SO, WE WOULD HAVE OBSERVED THE XING REQUIREMENT, THUS COMPLYING AFTER RECEIVING THE APCH CLRNC, EVEN IF ATC HAD NEGLECTED TO INSTRUCT US TO DO SO.
