Narrative:
During departure with numerous traffic in the area. We received a TCASII advisory of TA, followed by RA 'descend, descend' vertical speed 2500 FPM down. Notified departure control. They advised us of uncontrolled traffic, no altitude information, in that area. This was our first call on that traffic.
