So a process has begun, with the end of life/support on Connect Plus systems, Industrial Communications and Electronics have begun transitioning over to a DMR Tier III trunked radio system.

So far between Bill, Jeff and myself, we've identified four sites that have active DMR Tier III control channels
S15 (DSD 1.2) - Marshfield - 936.6250 CC15
S02 (DSD 6.1) - Quincy - 939.1500 CC02
S07 (DSD ???) - Foxboro - 935.5875 CC0
S27 (DSD ???) - West Bridgewater - 938.7500 CC12
(Interestingly, WB also has a 938.7000 still as a CON+ Control channel.)

Other sites I have received
09 Taunton, 10 Fall River, and 28 Freetown remain CON+ only.

All updates to the system should be posted to this sticky thread.
 
A couple of questions as I try to reprogram, if that's the word, DSD+.

For Quincy I'm still getting Con+ on 935.2125, but TIII on 939.1500. At least most of the time.

Network is still 134?

Site for Quincy is 6.1?

What do the Talk Groups look like on TIII?

It looks like the best approach will be to set up two ICE 900 networks in DSDPlus and see what happens.

Thoughts?
 
Duh. I just realized that the best way to get some of this information is to just run DSD+, without the trunking switches.

Forboro show Site L1-36. It also shows NL with Sites 40, 65, and 66. DCC is still 7.

Quincy shows Site L1-40 on 939.1500. I'm not sure how to translate that to what you posted Mike.

W. Bridgewater shows Site L1-32 on 938.75000.

It's going to be like the old days when this network was first being built out.

So far frequencies and DCC seem the same.
 
The 536 shows the network as being "Net 1", but I believe that, that refers to the "DMR Region", so "1.32" (West Bridgewater) is Region 1, Site 32.
 
I have, I think. Quincy should be 1.40 then?

I'm not close to ready to reprogramming either my 536 or SDS scanners. Never mind the 325P2

The DSDPlus Sites are reported based on a (minor?) flaw in calculating in the program. If I recall, there was some questions with the reading of the standard which resulted in the DSDPlus Site numbering starting 1 digit below what is correct. This translates to DSDPlus Site 1.1 being Uniden Site 0 (which isn't used), 1.2=1, 1.3=2, etc. 2.1=8, 3.1=16, 4.1=24, 5.1=32. I find it easier to create a spreadsheet with the two side by side and then enter channel numbers and frequencies horizontally to flesh out each system.
Don't forget, DSDPlus uses LSN (Slot numbers) and Uniden uses LCN (Channel numbers). The OneVoice Tier III Site I have seen uses DSDPlus LSN 695 for the control channel which is Uniden LCN 348 which is (LSN+1)/2

Would it help to put a correlation table into the wiki between DSD and Uniden Site IDs.?

IIRC on the LSN, if it is an odd number, it's always the LSN+1 but if it is an even number, it's just divided by 2.
 
This is starting to come back to me a bit. The last time I did anything with a TIII system was before the pandemic. Fortunately, I set a couple up in DSD+ and kept the notes.

Quincy shows 939.1500 as Channel 665 in DSD+.

Rather type this all in, I'll take a screen shot with my camera and post it. That way hopefully we can decipher it.

This is from Quincy running 939.1500 as the control channel.

It would help me!

This is going to take some ciphering...
Those ICE Tier III Site numbers are not the same format as the new OneVoice Tier III, Eversource (CT) Tier III, or Marcus Tier III (those 3 systems use x.x format).
Perhaps it is because the ICE system does not use a bandplan but instead uses custom channel numbers.

On the 325P2, you could create a custom search for a range that covers one of the ICE control channels. Choose the Control Channel Only option. Once the search hits the active ICE CC, hit HOLD and after a couple seconds, the scanner should show NET1, Sxxx. I would wonder if the Site number that the Uniden reports is the same and the DSDPlus ones?

I am not seeing any new Tier III on 900 yet in western MA.

I set up a custom search, but it doesn't see 939.1500. I used the entire band from 935.00 to 940.000 and it see multiple control channels for the Con+ sites, but nothing for the TIII sites. For the Con+ sites it shows Network, Site, and Color Code. It even shows TG numbers. It does nothing on 939.150.

The Con+ Control Channel for Quincy is still active. I wonder if the TIII stuff isn't fully activated yet?

Final Edit for tonight. Looking at 939.1500 on DSD+, it's doing the same thing, so it's not the 325P2 they just have turned something on off for now. Same thing on the Foxboro TIII control channel that was live earlier today.

Sites 11, 12, and 1 are still Con+

Edit: and sites 14 and 29 still Con+ also.
 
Seems (IMHO) they have only taken 1 Freq from those 4 sites, to just run the CC for the TIII

Based on logging Quincy, as Con+ for all the known Frequencies, minus the new TIII allocation.
Same for Marshfield

Same for West Bridgewater and Foxboro. I think that this is just the beginning of the process. Which brings up o couple of other questions. Is this a software update only, or does the hardware need to be replaced? Same question for the bases and the mobiles. If it's software only, I'm assuming that it will all be done over the air for the mobiles and whatever portables there may be.

This morning Quincy was running TIII control data on 939.1500, but no traffic.

The 325P2 still doesn't stop on any of the TIII control channels within range (Quincy, Foxboro, W. Bridgewater) Based on what CG wrote, I think that it should be seeing that data and producing information. All of the Con+ control channels in range are spitting out information that matches the Wiki. The custom search I set up is for the freq. range of 935.000 - 940.0000 and it's seeing a lot of data.

I don't know what's going on with that.

Quincy (DSD+) 939.1500 is now showing as 1.41

Don't run it as a trunking control channel. Just run it as regular DSD using FMP24. For some reason DSD-CC doesn't show the data properly.

Back when we were trying to figure out the MCCA TIII Hytera system, DSD-CC worked fine, so it must be something with the Motorola implementation. It's still early in the deployment of the ICE TIII system, so it's going to be another adventure just as it was when they moved from analog to Con+.

DSD+ doesn't even show a neighbor list, for the TIII :(
