Narrative:
Departure control was very busy with one controller working several frequencys. We leveled off at 10000 ft (clearance limit). A TCASII alert occurred with a pop up traffic at 5-7 mi and 700 ft above descending. TCASII commanded a 3000-4000 FPM climb. I disengaged the autoplt and started the climb. I visually acquired the traffic and started a right turn to provide more separation. The other aircraft, a commuter airliner (light transport aircraft) went about 700 ft below. 2 mi off the left side I stopped the climb at 10700 ft and started a descent back to 10000. The captain (not flying) notified ATC of the deviation. He cleared us to climb 17000 and handed us off to abq center.

Title: FLC OF ACR MLG ACFT DEVIATED FROM ASSIGNED ALT IN RESPONSE TO A TCASII RA.
Narrative: DEP CTL WAS VERY BUSY WITH ONE CTLR WORKING SEVERAL FREQS. WE LEVELED OFF AT 10000 FT (CLRNC LIMIT). A TCASII ALERT OCCURRED WITH A POP UP TFC AT 5-7 MI AND 700 FT ABOVE DSNDING. TCASII COMMANDED A 3000-4000 FPM CLB. I DISENGAGED THE AUTOPLT AND STARTED THE CLB. I VISUALLY ACQUIRED THE TFC AND STARTED A R TURN TO PROVIDE MORE SEPARATION. THE OTHER ACFT, A COMMUTER AIRLINER (LTT ACFT) WENT ABOUT 700 FT BELOW. 2 MI OFF THE L SIDE I STOPPED THE CLB AT 10700 FT AND STARTED A DSCNT BACK TO 10000. THE CAPT (NOT FLYING) NOTIFIED ATC OF THE DEV. HE CLRED US TO CLB 17000 AND HANDED US OFF TO ABQ CTR.
