The system is Phase 1 and there are no plans to move to Phase 2. The db should be updated to reflect this.

Traffic from the Barberton, Clinton, or Fairlawn sites would only be heard on the 3600 simulcast cell if a user has affiliated with the 3600 simulcast cell and it would be limited to the talkgroup they are using.
This is from the MARCS IP thread:
Observing phase 2 trunking tables transmitted on the control channel is not a reliable indication that a system has purchased a phase 2 software license. By default Motorola P25 systems version 7.11 or newer will send phase 2 tables even if the feature was not purchased. MARCS-IP is currently version 7.13
The only sure fire method to confirm if a system is truly phase 2 capable is to observe p2 voice channel grants.
I know a few of you have reported hearing some traffic from the P25 agencies on the non-P25 system. I had a chance to talk to a PD friend of mine. I didn't even mention it, but he did say they were told their radios would "switch to Hardy Rd" if they had reception problems.
It sounds like what he's trying to describe is patch between the two systems. Hardy Rd is one of the simulcast sites on the non-P25 Summit system. I don't know if the patch is always there, or is only triggered under a certain condition. Keep your ears on the Summit800 deprecated talkgroups to see if any have traffic and need to be undeprecated.

Not a patch and radios won't automatically switch to the simulcast sites. The three 9600 sites (P25) and the 3600 simulcast cell are controlled by a common master site. Within the master site is a SMARTX site converter, essentially an intelligent router. The SMARTX will route traffic between the 9600 and 3600 sites if there are radios affiliated on these sites on the same talkgroup. Users must select which site they are operating on, the radios are not capable of automatically switching between 3600 and 9600 systems. Each radio has a 9600 zone and 3600 zone with the same talkgroup line up. The need to manually select sites will be eliminated next year when all sites are upgraded to 9600.
Thanks Mike! The current setup is three independent sites. Will there be a time when all sites will be integrated as a single simulcast site with multiple transmitters, thus eliminating the need to have each site programmed into a scanner for full coverage?

Yes, the project is expected to begin in Q1 of 2016. The end result will be a 10 site / 25 channel simulcast system with redundant prime site and connectivity to MARCS. Presentation available at: https://800mhz.summitoh.net/images/stories/PDFs/P25/p25_project.pdf
I un-deprecated several talkgroups on the non-P25 system today. I'd been hearing traffic on these over the last week, so I put a 436HP to work on discovery. I only re-enabled those that were known to be used as back-ups (per mszabo2000's info above).
Note there are others that probably should be monitored. I think I heard a PD using S CRT2 (32880), possibly Barberton. There was also a report a year ago that S ADM (32144) and S OPS-1 (32176) were moved to Jail talkgroups. If these can be confirmed, please submit them.

anybody knows what is the talk group 2075 if anybody knows let me know
I believe 2075 was a Copley FD fire ground TG.. But never heard it identified during incident last night, but it was Copley FD units. Not enough info to submit.
TG 2075 seems to be a MAC channel on the P25 system ... Heard an Akron Fire run with Fairlawn this afternoon .. I locked on to 2075 and heard incident MAC traffic you would expect to
hear on Akron Summit 800 system.
When I released the 2075 talk group .. Next scanner traffic was same incident but was on Akron Summit MAC TG. So, wild guess here, during this evolution to P25, a MAC TG on Akron Summit 800 is duplicated on P25.. .??
hear on Akron Summit 800 system.

What site were you picking that up on? I heard it to and was assuming it was a temporary patch to someone's fireground.
The assumption is that this is MAC-2. But, I'd expect it to be active every time Akron and Fairlawn head out on a med run together. I don't think that 2075 is always active.

Any active TG on 8D27 will be broadcast on 6F4 if there is a radio affiliated to that TG on 6F4 and vice versa.
2075 was on summit P25.
Thanks Mszabo for the info .. So was 2075 the Mac 2 Channel on P25 or could it be it be whatever Akron Summit is assigned on Mac runs ?

If you convert 2075 to hex or multiple by 16 you'll see the results match MAC02 in the Summit 800 TG database.
Wow! That multiplier info is a great! I've been using it to cross-check new entries between the two systems.
For example, I heard traffic on 44432 on 800. It sounded like Barberton PD. 44432/16=2777. Well, look at that. 2777 on P25 is Barberton PD on P25.
I did the same with MAC Call. Plus, I had a radio on each system, so I was also able to hear the same traffic on both.
