Narrative:

Due to controller training, received late handoff over bdf to low altitude controller. At 23 northeast bdf, 24000 ft and 300 KTS received clearance to cross shooz intersection at 11000 ft and 250 KTS. As I initiated descent I realized we would be unable to comply with both altitude and airspeed restrictions. Unable to inform controller due to frequency congestion. Not knowing which was the more restrictive, dove for 11000. As we approached shooz, controller gave us a vector off the arrival route and questioned our airspeed. I don't know how this could have been prevented unless a lower workload for controller or some other method to reduce radio congestion could be found.

Title: ARTCC CTLR GIVES CLRNC FOR XING RESTRICTION WITH SPD LATE, AND FLC CANNOT COMPLY WITH SPD, BUT GETS ALT. FREQ CONGESTION PREVENTS FLC FROM ADVISING CTLR.

Narrative: DUE TO CTLR TRAINING, RECEIVED LATE HDOF OVER BDF TO LOW ALT CTLR. AT 23 NE BDF, 24000 FT AND 300 KTS RECEIVED CLRNC TO CROSS SHOOZ INTXN AT 11000 FT AND 250 KTS. AS I INITIATED DSCNT I REALIZED WE WOULD BE UNABLE TO COMPLY WITH BOTH ALT AND AIRSPD RESTRICTIONS. UNABLE TO INFORM CTLR DUE TO FREQ CONGESTION. NOT KNOWING WHICH WAS THE MORE RESTRICTIVE, DOVE FOR 11000. AS WE APCHED SHOOZ, CTLR GAVE US A VECTOR OFF THE ARR RTE AND QUESTIONED OUR AIRSPD. I DON'T KNOW HOW THIS COULD HAVE BEEN PREVENTED UNLESS A LOWER WORKLOAD FOR CTLR OR SOME OTHER METHOD TO REDUCE RADIO CONGESTION COULD BE FOUND.
