Narrative:
We were level at FL350 and had just transitioned from J64 to J78 when we were instructed to turn right to 360 degrees. We started our turn when we heard the controller instruct another aircraft to turn. We sensed concern with that call. He then gave us something like 'turn immediately', or 'give me a hard turn.' mind you, we were heading from what I can remember about 240 degrees at FL310 at mach .76. I saw the aircraft, but it was hard to tell at night how close he was visually. I quickly looked at my speed and put the bank to 30 degrees. While we were about 1/2 way through the turn, we received a TA alert, followed immediately by an RA alert to climb. I clocked off the autoplt and started climbing. We told ATC we were responding to an RA. I think he knew it, and we climbed about 700 ft and then got 'monitor vertical speed' and then 'clear of conflict.' I would estimate elapsed time from the first instruction to turn to the RA alert was less than 90 seconds. During this time, believe it or not, my #1 flight attendant was delivering the meals. She did a great job and realized we were busy and responded accordingly.

Title: MD80 CREW HAD A TCASII RA IN ZOB CLASS A AIRSPACE.
Narrative: WE WERE LEVEL AT FL350 AND HAD JUST TRANSITIONED FROM J64 TO J78 WHEN WE WERE INSTRUCTED TO TURN R TO 360 DEGS. WE STARTED OUR TURN WHEN WE HEARD THE CTLR INSTRUCT ANOTHER ACFT TO TURN. WE SENSED CONCERN WITH THAT CALL. HE THEN GAVE US SOMETHING LIKE 'TURN IMMEDIATELY', OR 'GIVE ME A HARD TURN.' MIND YOU, WE WERE HDG FROM WHAT I CAN REMEMBER ABOUT 240 DEGS AT FL310 AT MACH .76. I SAW THE ACFT, BUT IT WAS HARD TO TELL AT NIGHT HOW CLOSE HE WAS VISUALLY. I QUICKLY LOOKED AT MY SPD AND PUT THE BANK TO 30 DEGS. WHILE WE WERE ABOUT 1/2 WAY THROUGH THE TURN, WE RECEIVED A TA ALERT, FOLLOWED IMMEDIATELY BY AN RA ALERT TO CLB. I CLOCKED OFF THE AUTOPLT AND STARTED CLBING. WE TOLD ATC WE WERE RESPONDING TO AN RA. I THINK HE KNEW IT, AND WE CLBED ABOUT 700 FT AND THEN GOT 'MONITOR VERT SPD' AND THEN 'CLR OF CONFLICT.' I WOULD ESTIMATE ELAPSED TIME FROM THE FIRST INSTRUCTION TO TURN TO THE RA ALERT WAS LESS THAN 90 SECONDS. DURING THIS TIME, BELIEVE IT OR NOT, MY #1 FLT ATTENDANT WAS DELIVERING THE MEALS. SHE DID A GREAT JOB AND REALIZED WE WERE BUSY AND RESPONDED ACCORDINGLY.
