Narrative:

Climbing on drake 6 STAR from phx runway 26R, 2 mi after 9 DME turn to 360 degrees between 4000 ft climb to 5000 ft MSL. Received TCASII RA to 'descend, crossing descend.' vsi target was 2000 FPM down while existing climb rate to 8000 ft was plus 2500 FPM. RA showed for only approximately 15-20 seconds during which time we arrested climb to level flight. RA disappeared and we resumed climb to 8000 ft MSL assigned. Advised ATC during RA and was told of small aircraft 6 NM wnw distant, same course that we were outclbing by plus 1500 FPM. Controller indicated that, while we did climb through his altitude, we were never closer than 6 NM and, at the time of the RA, were plus 1000 ft above traffic. Never saw the traffic. TCASII showed traffic at almost 5 NM 500 ft below climbing.
