Descending air carrier large transport gets a TCASII RA and climbs to avoid conflict with air carrier freighter on a buster SID departure procedure. Reporter feels that freighters are long overdue the requirement for having a TCASII system on board as per the regulations for other part 121 aircraft.

Narrative:
When cleared from 10000 ft to 9000 ft, received an RA at 9500 ft to climb. At 9800 ft RA cleared. Told ATC of RA and climb. Then received another RA to climb. Climbed to 10200 ft, RA cleared. ATC told us we were clear of aircraft and we finally descended to 9000 ft. Never had visual contact with intruder aircraft. After a phone call with supervisor in new york TRACON, I was told nothing we did was in question, but it appeared that a cargo aircraft had busted a SID and they were pulling the tapes. Now more than ever I feel that the requirement for TCASII on cargo aircraft is long overdue!
