Narrative:

On final approach ILS runway 9L to ft lauderdale inside marker on GS at approximately 1100 ft. Received TCASII 'traffic, traffic' off our right followed shortly by TCASII RA 'climb, climb.' we did and then saw traffic passing beneath us right to left indicating 1100 ft on our TCASII. We had climbed to 1300-1400 ft by this time. As I was attempting to call fll tower to advise them of our RA and climb, they called us reporting this traffic. Tower was in contact with traffic (some corporate jet) and asking them if they had us in sight, but never said a word to us until after our RA. Traffic was on a different frequency and not responding to fll tower.

Title: ACR HAS NMAC WITH A CGA JET IN CLASS C AIRSPACE. REACTS TO TCASII RA.

Narrative: ON FINAL APCH ILS RWY 9L TO FT LAUDERDALE INSIDE MARKER ON GS AT APPROX 1100 FT. RECEIVED TCASII 'TFC, TFC' OFF OUR R FOLLOWED SHORTLY BY TCASII RA 'CLB, CLB.' WE DID AND THEN SAW TFC PASSING BENEATH US R TO L INDICATING 1100 FT ON OUR TCASII. WE HAD CLBED TO 1300-1400 FT BY THIS TIME. AS I WAS ATTEMPTING TO CALL FLL TWR TO ADVISE THEM OF OUR RA AND CLB, THEY CALLED US RPTING THIS TFC. TWR WAS IN CONTACT WITH TFC (SOME CORPORATE JET) AND ASKING THEM IF THEY HAD US IN SIGHT, BUT NEVER SAID A WORD TO US UNTIL AFTER OUR RA. TFC WAS ON A DIFFERENT FREQ AND NOT RESPONDING TO FLL TWR.
