Narrative:
Standard call 1000 ft below level off altitude was made by PNF (me) with proper response by PF (copilot). Traffic collision avoidance system (TCASII) gave a traffic alert. All 3 crew members immediately looked at the system screen to determine location and then outside. ATC called 2 airplanes for us to watch for. While we were looking for the traffic the altitude alert sounded indicating a deviation at 500 ft above altitude. The excursion was no more than 450 ft high with an immediate return to 10000 ft. ATC never gave any indication that there had been a deviation or any inquiry as to our altitude. All of us were obviously distraction by the ATC traffic calls and the TCASII alert. As captain I need to be more sure that someone is flying the airplane and not spending that much time looking outside. There was no near miss or real traffic conflict.

Title: ACR LGT FLC OF 3 ALL DISTR BY TCASII TA ALLOWED AN ALT OVERSHOOT TO OCCUR DURING DEP FROM DEN.
Narrative: STANDARD CALL 1000 FT BELOW LEVEL OFF ALT WAS MADE BY PNF (ME) WITH PROPER RESPONSE BY PF (COPLT). TFC COLLISION AVOIDANCE SYS (TCASII) GAVE A TFC ALERT. ALL 3 CREW MEMBERS IMMEDIATELY LOOKED AT THE SYS SCREEN TO DETERMINE LOCATION AND THEN OUTSIDE. ATC CALLED 2 AIRPLANES FOR US TO WATCH FOR. WHILE WE WERE LOOKING FOR THE TFC THE ALT ALERT SOUNDED INDICATING A DEV AT 500 FT ABOVE ALT. THE EXCURSION WAS NO MORE THAN 450 FT HIGH WITH AN IMMEDIATE RETURN TO 10000 FT. ATC NEVER GAVE ANY INDICATION THAT THERE HAD BEEN A DEV OR ANY INQUIRY AS TO OUR ALT. ALL OF US WERE OBVIOUSLY DISTR BY THE ATC TFC CALLS AND THE TCASII ALERT. AS CAPT I NEED TO BE MORE SURE THAT SOMEONE IS FLYING THE AIRPLANE AND NOT SPENDING THAT MUCH TIME LOOKING OUTSIDE. THERE WAS NO NEAR MISS OR REAL TFC CONFLICT.
