Narrative:
Bdl approach had us descending to 5000 ft. About the time we were leveling off at 5000 ft approach issued a left turn to 140 degrees and called traffic at our altitude. He then told us to make it a tight turn for the traffic. About that time we received a TA followed by a RA on the TCASII to descend. While receiving the TA I noticed a TA for an aircraft 500 below us, which as we descended, we then received an RA for the aircraft below us to stop our descent. The first officer was flying and had a visual on the first aircraft, however, we never did see the aircraft below us which according to the TCASII was less than 1 mi. Approach control said he was not showing any aircraft below us. I have no explanation why the controller was not showing the aircraft below us. However, assuming one was there, the TCASII worked perfectly.

Title: RPTR RECEIVED A TCASII RA FOR AN ACFT ABOVE CALLING FOR A DSCNT ONLY TO RECEIVE A TCASII RA FOR AN ACFT BELOW TELLING THE RPTR TO STOP DSCNT.
Narrative: BDL APCH HAD US DSNDING TO 5000 FT. ABOUT THE TIME WE WERE LEVELING OFF AT 5000 FT APCH ISSUED A L TURN TO 140 DEGS AND CALLED TFC AT OUR ALT. HE THEN TOLD US TO MAKE IT A TIGHT TURN FOR THE TFC. ABOUT THAT TIME WE RECEIVED A TA FOLLOWED BY A RA ON THE TCASII TO DSND. WHILE RECEIVING THE TA I NOTICED A TA FOR AN ACFT 500 BELOW US, WHICH AS WE DSNDED, WE THEN RECEIVED AN RA FOR THE ACFT BELOW US TO STOP OUR DSCNT. THE FO WAS FLYING AND HAD A VISUAL ON THE FIRST ACFT, HOWEVER, WE NEVER DID SEE THE ACFT BELOW US WHICH ACCORDING TO THE TCASII WAS LESS THAN 1 MI. APCH CTL SAID HE WAS NOT SHOWING ANY ACFT BELOW US. I HAVE NO EXPLANATION WHY THE CTLR WAS NOT SHOWING THE ACFT BELOW US. HOWEVER, ASSUMING ONE WAS THERE, THE TCASII WORKED PERFECTLY.
