Have a few questions, An Announcement Group is already configured on system in question. Motorola P25 TDMA
My understanding is the following- someone correct me if I am wrong. Once sysadmin builds & activates the ANN Group, an authorized unit that has this TG set in the radio that can transmit on it can key up and the transmission gets re-broadcasted over all TG's in the AG at the same time. This has been tested and is working.
My understanding that the Announcement Group field within a Trunked Personality, when filled out with valid ANN GRP data, and receiving a transmission on said ANN GRP, is that the radio will tune to or rather immediately receive the transmission coming over the ANN Group, regardless of what Trunked talkgroup the radio is set to, AND even if the radio is receiving audio on another talkgroup on the same system. Am I right in this belief?
Lastly and most importantly, Secure/Clear strapping of the Announcement Group. Of the radios involved, some talk-groups are encrypted and some are clear.
My question here is that if an emergency announcement is made, how would a radio determine to if it receives and plays audio or not on that Announcement Group, especially if ADP & AES (multiple keys) are used on various talk-groups. I hope I was clear with this. Anyone?
