Narrative:

XX20Z, 11000 ft, dfw approach. Location: ukw 4 arrival. Prior to siler intersection we were given the ukw 4 arrival to dfw with delete all speed on the STAR. Prior to siler intersection we were given a turn to the south. We were in the process of slowing, with slat/flap confign, and turning. Approach had pointed out traffic departing from dfw. In the turn we received a TA followed by an immediate RA to monitor vertical descent, then a descend RA. We followed the RA to the least altitude loss due to the dfw climbing traffic. We then got a reverse RA to climb, followed by another monitor vertical descent. At clear of conflict, we were 350-400 ft below our assigned altitude of 11000 ft. We verified the altitude wanted by approach and returned to that altitude. We told approach that we were responding to an RA. We continued with a normal landing. I don't know if an altitude conflict was created due to the RA, or if the RA kept us from having an altitude conflict. We never saw anyone above us, but knew that we did have traffic below us climbing. I don't know at what rate the traffic below us was climbing.

Original NASA ASRS Text

Title: AN MD SUPER 80 ON RADAR VECTORS AT DFW RECEIVED A TCASII ALERT 'MONITOR VERT SPD' FOLLOWED BY A 'DSND RA.' ALMOST IMMEDIATELY THE TCASII ISSUED A 'CLB RA' FOLLOWED BY A 'MONITOR VERT SPD.' THE RPTR HAD BEEN ISSUED CLBING TFC NEAR HIS POS BY TRACON.

Narrative: XX20Z, 11000 FT, DFW APCH. LOCATION: UKW 4 ARR. PRIOR TO SILER INTXN WE WERE GIVEN THE UKW 4 ARR TO DFW WITH DELETE ALL SPD ON THE STAR. PRIOR TO SILER INTXN WE WERE GIVEN A TURN TO THE S. WE WERE IN THE PROCESS OF SLOWING, WITH SLAT/FLAP CONFIGN, AND TURNING. APCH HAD POINTED OUT TFC DEPARTING FROM DFW. IN THE TURN WE RECEIVED A TA FOLLOWED BY AN IMMEDIATE RA TO MONITOR VERT DSCNT, THEN A DSND RA. WE FOLLOWED THE RA TO THE LEAST ALT LOSS DUE TO THE DFW CLBING TFC. WE THEN GOT A REVERSE RA TO CLB, FOLLOWED BY ANOTHER MONITOR VERT DSCNT. AT CLR OF CONFLICT, WE WERE 350-400 FT BELOW OUR ASSIGNED ALT OF 11000 FT. WE VERIFIED THE ALT WANTED BY APCH AND RETURNED TO THAT ALT. WE TOLD APCH THAT WE WERE RESPONDING TO AN RA. WE CONTINUED WITH A NORMAL LNDG. I DON'T KNOW IF AN ALT CONFLICT WAS CREATED DUE TO THE RA, OR IF THE RA KEPT US FROM HAVING AN ALT CONFLICT. WE NEVER SAW ANYONE ABOVE US, BUT KNEW THAT WE DID HAVE TFC BELOW US CLBING. I DON'T KNOW AT WHAT RATE THE TFC BELOW US WAS CLBING.

An md super 80 on radar vectors at dfw received a TCASII alert 'monitor vertical speed' followed by a 'descend RA.' almost immediately the TCASII issued a 'climb RA' followed by a 'monitor vertical speed.' the reporter had been issued climbing traffic near his position by TRACON.
