Narrative:
ZBW. Location: 50 NM west pvd, norwich arrival. Level at FL210 with captain as PF, captain gave me the aircraft to make arrival PA. After giving me the aircraft and checking off, ATC made a TA for an aircraft climbing to FL200 at our 10 O'clock position. I acquired the aircraft at 8 NM and confirmed it was climbing on the TCASII. A few seconds later we got an RA to climb with 100 FPM command. I disconnected the autoplt and autothrottle and started a climb to comply with the RA. Maximum deviation from assigned altitude was 500 ft. Using the TCASII, I confirmed that our traffic had overshot his altitude by 500 ft. This was a good example of making sure you really are in control of the aircraft when the other guy says 'you have it.'

Title: B757 HAS TO CLB 500 FT ON A TCASII RA WHEN OPPOSITE DIRECTION TFC OVERSHOOTS ITS ASSIGNED ALT BY 500 FT, 50 MI W OF PVD, RI.
Narrative: ZBW. LOCATION: 50 NM W PVD, NORWICH ARR. LEVEL AT FL210 WITH CAPT AS PF, CAPT GAVE ME THE ACFT TO MAKE ARR PA. AFTER GIVING ME THE ACFT AND CHKING OFF, ATC MADE A TA FOR AN ACFT CLBING TO FL200 AT OUR 10 O'CLOCK POS. I ACQUIRED THE ACFT AT 8 NM AND CONFIRMED IT WAS CLBING ON THE TCASII. A FEW SECONDS LATER WE GOT AN RA TO CLB WITH 100 FPM COMMAND. I DISCONNECTED THE AUTOPLT AND AUTOTHROTTLE AND STARTED A CLB TO COMPLY WITH THE RA. MAX DEV FROM ASSIGNED ALT WAS 500 FT. USING THE TCASII, I CONFIRMED THAT OUR TFC HAD OVERSHOT HIS ALT BY 500 FT. THIS WAS A GOOD EXAMPLE OF MAKING SURE YOU REALLY ARE IN CTL OF THE ACFT WHEN THE OTHER GUY SAYS 'YOU HAVE IT.'
