Narrative:

Our clearance was to depart okc, as filed, maintain 5000 ft and after takeoff turn right heading 010 degrees. After takeoff on runway 35R, we were switched to departure control. We attempted contact and received no response, initially. Departure then called another aircraft and proceeded to have a conversation about crossing the field at 3500 ft and other assorted subjects. After I set quiet EPR at about 2700 ft MSL, our rate of climb decreased to about 1000 FPM. The first officer was able to contact departure control and he responded, 'turn right 040 degrees and maintain 3000 ft MSL.' we were passing 2900 ft MSL when the revised clearance was received. As captain and the PF, I pushed the nose over, but reached 3100 ft when simultaneously we received a traffic alert, followed immediately by a TCASII RA 'monitor vertical speed,' during which I was descending back to 3000 ft MSL. The vsi TCASII display showed a target at +500 ft pass overhead. I asked the controller for a phone number. Later that day, I talked with the okc supervisor. He had not been on duty at the time, but said they would look into it.

Title: A DEPARTING B737 CLBING TO 5000 FT IS STOPPED AT 3000 FT DUE TO TFC XING ABOVE. THE B737 RECEIVED A TCASII RA INDICATING THAT THE OTHER ACFT CROSSED LESS THAN 500 FT ABOVE HIM.

Narrative: OUR CLRNC WAS TO DEPART OKC, AS FILED, MAINTAIN 5000 FT AND AFTER TKOF TURN R HDG 010 DEGS. AFTER TKOF ON RWY 35R, WE WERE SWITCHED TO DEP CTL. WE ATTEMPTED CONTACT AND RECEIVED NO RESPONSE, INITIALLY. DEP THEN CALLED ANOTHER ACFT AND PROCEEDED TO HAVE A CONVERSATION ABOUT XING THE FIELD AT 3500 FT AND OTHER ASSORTED SUBJECTS. AFTER I SET QUIET EPR AT ABOUT 2700 FT MSL, OUR RATE OF CLB DECREASED TO ABOUT 1000 FPM. THE FO WAS ABLE TO CONTACT DEP CTL AND HE RESPONDED, 'TURN R 040 DEGS AND MAINTAIN 3000 FT MSL.' WE WERE PASSING 2900 FT MSL WHEN THE REVISED CLRNC WAS RECEIVED. AS CAPT AND THE PF, I PUSHED THE NOSE OVER, BUT REACHED 3100 FT WHEN SIMULTANEOUSLY WE RECEIVED A TFC ALERT, FOLLOWED IMMEDIATELY BY A TCASII RA 'MONITOR VERT SPD,' DURING WHICH I WAS DSNDING BACK TO 3000 FT MSL. THE VSI TCASII DISPLAY SHOWED A TARGET AT +500 FT PASS OVERHEAD. I ASKED THE CTLR FOR A PHONE NUMBER. LATER THAT DAY, I TALKED WITH THE OKC SUPVR. HE HAD NOT BEEN ON DUTY AT THE TIME, BUT SAID THEY WOULD LOOK INTO IT.
