IDAS

Does IDAS systems use a RAN code? I am monitoring a system that is using IDAS but my software does not display a RAN number. It also displays group call, TG # 33554433, but no ran code and when i program that tg into my radio, which is a icom F4262, the software changes the TG # to a different number. The freq is 463.450, IDAS site 13. Oh, i am decoding with dsd+. Thanks all
