Narrative:
We leveled at 11000' on scy arrival to dfw; aircraft was equipped with TCAS. We picked up a target as a 'TA' 2000' altitude at 12 0'clock. It rapidly changed to 1600' the to RA and TCAS directed an aural pull up. As per TCAS procedure, we initiated a climb. At 12000' TCAS reported clear of traffic and we descended back to 11000'. Throughout the maneuver, we were unable to communication with ATC. We never saw the target aircraft as it was behind us after the maneuver.

Title: TCASII RA CAUSED FLT CREW TO CLIMB UNTIL RA ELIMINTED. REGAINED ASSIGNED ALT ADVISED CTLR.
Narrative: WE LEVELED AT 11000' ON SCY ARR TO DFW; ACFT WAS EQUIPPED WITH TCAS. WE PICKED UP A TARGET AS A 'TA' 2000' ALT AT 12 0'CLOCK. IT RAPIDLY CHANGED TO 1600' THE TO RA AND TCAS DIRECTED AN AURAL PULL UP. AS PER TCAS PROC, WE INITIATED A CLB. AT 12000' TCAS RPTED CLR OF TFC AND WE DSNDED BACK TO 11000'. THROUGHOUT THE MANEUVER, WE WERE UNABLE TO COM WITH ATC. WE NEVER SAW THE TARGET ACFT AS IT WAS BEHIND US AFTER THE MANEUVER.
