Narrative:
I was off center frequency (atlanta 135.35) advising flight attendants that we were out of 10000 ft MSL per company procedures, after advising captain that I would do so. Our clearance for climb was to 12000 ft MSL. While off frequency, our climb continued, and as the captain approached 12000 ft I reported back on primary communication frequency and I restated to the captain that 12000 ft was our assigned altitude. The captain said 'thank you' for reminding of said altitude, but level off was at about 12080 ft. ZTL questioned our altitude as 12200 ft and I replied that it was about 12080 ft MSL. Center asked if we had gone through 12000 ft and I advised that we were about 80 ft high. Center did not indicate any problem, nor did TCASII, but I wanted to show how this can happen when each pilot is busy with required calls outside of primary communication frequency. Any time 'out of the loop,' is risky.

Title: ALTDEV ON CLBOUT. PNF, FO AND ATC ALERTED THE CAPT, PF, WHO RETURNED TO ASSIGNED ALT.
Narrative: I WAS OFF CTR FREQ (ATLANTA 135.35) ADVISING FLT ATTENDANTS THAT WE WERE OUT OF 10000 FT MSL PER COMPANY PROCS, AFTER ADVISING CAPT THAT I WOULD DO SO. OUR CLRNC FOR CLB WAS TO 12000 FT MSL. WHILE OFF FREQ, OUR CLB CONTINUED, AND AS THE CAPT APCHED 12000 FT I RPTED BACK ON PRIMARY COM FREQ AND I RESTATED TO THE CAPT THAT 12000 FT WAS OUR ASSIGNED ALT. THE CAPT SAID 'THANK YOU' FOR REMINDING OF SAID ALT, BUT LEVEL OFF WAS AT ABOUT 12080 FT. ZTL QUESTIONED OUR ALT AS 12200 FT AND I REPLIED THAT IT WAS ABOUT 12080 FT MSL. CTR ASKED IF WE HAD GONE THROUGH 12000 FT AND I ADVISED THAT WE WERE ABOUT 80 FT HIGH. CTR DID NOT INDICATE ANY PROB, NOR DID TCASII, BUT I WANTED TO SHOW HOW THIS CAN HAPPEN WHEN EACH PLT IS BUSY WITH REQUIRED CALLS OUTSIDE OF PRIMARY COM FREQ. ANY TIME 'OUT OF THE LOOP,' IS RISKY.
