Narrative:

I was the PNF. After climbing out of pit, we were given a clearance to 14000 ft, which I set in the altitude select and was confirmed by the captain. After passing through 10000 ft, as per company procedure, the captain monitored the center frequency while I changed to the company frequency to give our 'off' and 'out' times. After several attempts I was unable to raise pittsburgh operations. I then tried to raise atlanta radio several times and was unable to raise them as well. I then told the captain that I was unable to raise either operations. He continued to monitor the center frequency while I made a PA announcement to the passenger. Passing through 20000 ft, I heard 'traffic' that was followed by an RA in which I stopped in the middle of the PA announcement. I saw the captain was making corrective action, so I leaned forward to look for traffic. I saw the traffic at 1 O'clock position, 1-2 mi and 1000 ft above, but was unable to determine the type of aircraft. At that point, I was back on center frequency and the controller told us to descend to 20000 ft.

Title: FLC RECEIVES TCASII RA WARNING.

Narrative: I WAS THE PNF. AFTER CLBING OUT OF PIT, WE WERE GIVEN A CLRNC TO 14000 FT, WHICH I SET IN THE ALT SELECT AND WAS CONFIRMED BY THE CAPT. AFTER PASSING THROUGH 10000 FT, AS PER COMPANY PROC, THE CAPT MONITORED THE CTR FREQ WHILE I CHANGED TO THE COMPANY FREQ TO GIVE OUR 'OFF' AND 'OUT' TIMES. AFTER SEVERAL ATTEMPTS I WAS UNABLE TO RAISE PITTSBURGH OPS. I THEN TRIED TO RAISE ATLANTA RADIO SEVERAL TIMES AND WAS UNABLE TO RAISE THEM AS WELL. I THEN TOLD THE CAPT THAT I WAS UNABLE TO RAISE EITHER OPS. HE CONTINUED TO MONITOR THE CTR FREQ WHILE I MADE A PA ANNOUNCEMENT TO THE PAX. PASSING THROUGH 20000 FT, I HEARD 'TFC' THAT WAS FOLLOWED BY AN RA IN WHICH I STOPPED IN THE MIDDLE OF THE PA ANNOUNCEMENT. I SAW THE CAPT WAS MAKING CORRECTIVE ACTION, SO I LEANED FORWARD TO LOOK FOR TFC. I SAW THE TFC AT 1 O'CLOCK POS, 1-2 MI AND 1000 FT ABOVE, BUT WAS UNABLE TO DETERMINE THE TYPE OF ACFT. AT THAT POINT, I WAS BACK ON CTR FREQ AND THE CTLR TOLD US TO DSND TO 20000 FT.
