Okay,
I know for a fact there is more data being transmitted on the data-substream along in the voice channel on a Motorola APCO-16 or even APCO-25 trunked system, than typical through a conventional P25 repeater.
So, is there anyone that can, with a high degree of certainty or authority (please don't speculate if you don't know), know if there's some or all of the CC data stream is also being retransmitted on each of the voice channels to facilitate radios that use Priority scanning or things of that nature to change TGs based on activity on other talkgroups?
I can look up the APCO 25 draft and read for myself the layers within the voice channel transmission, and, I know that 9600bps = voice + data @ *xyz* symbols/secs each stream. But has the question been answered as to what extra data typically is transmitted on a trunked voice channel, besides the usual Transmitting UnitID Number, NAC Code, and radio-specific auxiliary data (like the numeric "Custom Status" numeric message ID, etc..) found on conventional channels?
Thanks,
