P25 trunking question

[jrothwell]

Is the way a P25 radio affiliates and the way audio is heard on a multi-site system, the same as it would be on a SmartZone system? It each site in a P25 trunked system the same as a zone in a SmartZone system? So, if a radio is affiliated to a site, the audio is only re-broadcast on that site unless a radio on the same TG is affiliated to another site?

Thanks.

Short answer: "It depends".

It's possible to define talkgroups to be always heard on certain sites, but it's common to set it up so that talkgroup traffic is only broadcast to sites where a radio is "logged in" to hear it (what you describe above).

It's also possible to forbid a TG from being relayed to a particular tower or set of towers. This might be used in a very wide area system where you don't want somebody to be able to tie up a tower site at the other end of a state with traffic intended for another region.

Yes and No.

Generally, many of those configurations are left up to the owner/techs.

In my State, the Inteli (Fill in the Gap) Repeaters work that way.
However the Simulcast Wide-Area zones can be configured by the Techs to
a. Always broadcast specific TG's
b. DisAllow specific TG's.

The only way to attempt to figure it out is to monitor, monitor, monitor and then throw in a little Chaos, such as a chase, shots fire, fires, Large Scale events...

Is the way a P25 radio affiliates and the way audio is heard on a multi-site system, the same as it would be on a SmartZone system?
