LGT ON CLBOUT HAS CLOSE PROX WITH SECOND ACFT ON ARR.

Narrative

ON THE FLT TO MCO FROM ATL; WE CAME RATHER CLOSE TO AN ARRIVING ACFT DURING OUR DEP. WE HAD DEPARTED ON RWY 26R; ONE OF THE PARALLEL RWYS ON THE N SIDE OF THE ARPT. AFTER WE BECAME AIRBORNE; DEP CTL GAVE US A CLB TO 14000 FT AND TURNED US ON A SOUTHERLY HDG TOWARD MCO. THE CREW BECAME A LITTLE CONCERNED BECAUSE OF A LITTLE CONFUSION WITH ATC ABOUT THE ACTUAL ALT THE OTHER ACFT WERE ASSIGNED TO THAT WERE BEING WORKED ON OUR FREQ. WE HEARD THAT THERE WAS ANOTHER ACFT APCHING ATL FROM THE SW AT 11000 FT AND IT APPEARED TO BE ON AN IMPACT COURSE WITH OUR FLT. AT 10250 FT; DEP ASKED US TO STOP OUR CLB AND RETURN TO 10000 FT. OUR SEPARATION LOOKED GOOD AS THE ACFT PASSED OVERHEAD AT 11000 FT. I FEEL THE PROB MAY HAVE BEEN A LACK OF COORD BTWN THE S AND N FEEDER CTLRS. OUR FLT DEPARTED ON THE N COMPLEX OF RWYS AND INSTEAD OF TURNING TO THE NW; WE WERE GIVEN A TURN TO THE S. THE TURN TO THE S IS NORMAL IN MOMENTS OF LOW TFC; HOWEVER; IT COULD PRESENT PROBS FOR THE S COMPLEX IF WE CLB THROUGH THEIR INBOUND FLTS AT 11000 FT. WE SHOULD HAVE BEEN HELD DOWN TO 10000 FT FOR THE S TURN OR TURNED OUT TO THE NW AND THEN TURNED S AFTER WE HAD CLBED ABOVE 11000 FT.
