ISSI requires P25, which DC is not.From my reading, it takes a heck of a lot more than just stuffing a key in to put a subscriber radio from one system on another system. Are these agencies using any type of RFsystem interface (ISSI?) to coordinate subscriber movement onto each others systems (if the encryption types were even the same)? Sounds to me like the Chief got fed a line that may blow back in somebody's face if the press keeps the issue in front of the public.
OK, thanks.. I guess the point still is - sharing an encryption key, even if the systems were compatible would at the most would just put a new subscriber on the other system - no interoperability. I guess that means somebody would still be carrying two radios.....ISSI requires P25, which DC is not.
