Narrative:
An uneventful takeoff from dal runway 31L and climb to 8000 ft on runway heading. The departure controller was saturated and gave us a turn (left) to 200 degrees and climb to 17000 ft. I think that he thought we were a B737-300 with much better climb performance. In short succession, left to 180 degrees, then left to 170 degrees, then right turn to 270 degrees and maintain 7000 ft. We were already passing 7700 ft ! We descended back to 7000 ft and were given company traffic 12 O'clock and 3 mi. We had a visual on company traffic and found out later that he was on another frequency and was told that we were climbing to 7000 ft. We passed behind company traffic and then were given a climb to 17000 ft. The controller was saturated and overtasked.

Title: B737 CREW OFF DAL WAS GIVEN NUMEROUS VECTOR HDGS BY A BUSY DFW DEP CTLR AND CONFLICTED WITH A COMPANY ACFT RESULTING IN AN OPERROR.
Narrative: AN UNEVENTFUL TKOF FROM DAL RWY 31L AND CLB TO 8000 FT ON RWY HDG. THE DEP CTLR WAS SATURATED AND GAVE US A TURN (L) TO 200 DEGS AND CLB TO 17000 FT. I THINK THAT HE THOUGHT WE WERE A B737-300 WITH MUCH BETTER CLB PERFORMANCE. IN SHORT SUCCESSION, L TO 180 DEGS, THEN L TO 170 DEGS, THEN R TURN TO 270 DEGS AND MAINTAIN 7000 FT. WE WERE ALREADY PASSING 7700 FT ! WE DSNDED BACK TO 7000 FT AND WERE GIVEN COMPANY TFC 12 O'CLOCK AND 3 MI. WE HAD A VISUAL ON COMPANY TFC AND FOUND OUT LATER THAT HE WAS ON ANOTHER FREQ AND WAS TOLD THAT WE WERE CLBING TO 7000 FT. WE PASSED BEHIND COMPANY TFC AND THEN WERE GIVEN A CLB TO 17000 FT.
