Narrative:
We were issued a descent clearance to cross 5 mi west of abe at 13000' to 19000', fairly close to the fix. This required a high rate of descent. I missed the crossing by approximately 1-2 mi. The controller queried our altitude and the first officer reported out of 13800' for 13000, my altimeter showed (as I recall) approximately 13500 for 13000' at that time. Controller advised that we had missed the crossing with a bit of a chuckle in his voice. I believe that there were many distrs on the communication frequency which required a strict listening watch. We were flight ed, there was a flight eabd and flight acd, also on frequency with other aircraft. These distrs and the fact that my crew and I had been on duty for almost 14 hours at that point and were all beginning to tire contributed to our missing this crossing restriction. There was also some turbulence requiring a simultaneous slowing of the aircraft which contributed. Probably should have advised the controller that it was going to be a tight crossing restriction, but I guess the frequency congestion altered that possibility. I did call the ny center on arrival and spoke to the controller who stated that there was no problem or conflict, etc, and that he mentioned it to only make us aware. He did say that at times that area is congested and that one could have a problem there if the other area airport departures and arrs are heavy.

Title: ACR LGT ALT DEVIATION CROSSING RESTRICTION NOT MET DURING DESCENT TOWARD ABE.
Narrative: WE WERE ISSUED A DSCNT CLRNC TO CROSS 5 MI W OF ABE AT 13000' TO 19000', FAIRLY CLOSE TO THE FIX. THIS REQUIRED A HIGH RATE OF DSCNT. I MISSED THE XING BY APPROX 1-2 MI. THE CTLR QUERIED OUR ALT AND THE F/O RPTED OUT OF 13800' FOR 13000, MY ALTIMETER SHOWED (AS I RECALL) APPROX 13500 FOR 13000' AT THAT TIME. CTLR ADVISED THAT WE HAD MISSED THE XING WITH A BIT OF A CHUCKLE IN HIS VOICE. I BELIEVE THAT THERE WERE MANY DISTRS ON THE COM FREQ WHICH REQUIRED A STRICT LISTENING WATCH. WE WERE FLT ED, THERE WAS A FLT EABD AND FLT ACD, ALSO ON FREQ WITH OTHER ACFT. THESE DISTRS AND THE FACT THAT MY CREW AND I HAD BEEN ON DUTY FOR ALMOST 14 HRS AT THAT POINT AND WERE ALL BEGINNING TO TIRE CONTRIBUTED TO OUR MISSING THIS XING RESTRICTION. THERE WAS ALSO SOME TURB REQUIRING A SIMULTANEOUS SLOWING OF THE ACFT WHICH CONTRIBUTED. PROBABLY SHOULD HAVE ADVISED THE CTLR THAT IT WAS GOING TO BE A TIGHT XING RESTRICTION, BUT I GUESS THE FREQ CONGESTION ALTERED THAT POSSIBILITY. I DID CALL THE NY CENTER ON ARR AND SPOKE TO THE CTLR WHO STATED THAT THERE WAS NO PROB OR CONFLICT, ETC, AND THAT HE MENTIONED IT TO ONLY MAKE US AWARE. HE DID SAY THAT AT TIMES THAT AREA IS CONGESTED AND THAT ONE COULD HAVE A PROB THERE IF THE OTHER AREA ARPT DEPS AND ARRS ARE HEAVY.
