What Is "DMR (MOT)"?

[CanesFan95]

DSD+ Fast Lane is showing "DMR (MOT)" in the Event Log footer. Anyone know what this means?

 

[apcofan]

It means that signal is transmitted by Motorola repeater

I saw this DMR (MOT) as well and wondered the same. But if its Trunk Mobile, Motorola is either Cap+ or Con+. Does Motorola have something different than these two for Tier 3 systems? Maybe something prior to Con+?

Thank you sir, but this doesn't necessarily answer the question. There are voice transmissions on the DMR (Mot) system as well, not just radio checks. Here is a snip from the decode logging:

Post #3 in that thread is about the closest to an explanation. So is Capacity Max the same thing as Tier III, or is it Motorola's proprietary ver$ion of Tier III? And therefore does "DMR (MOT)" mean Capacity Max?

The poster said "obviously", but I don't see how this is obvious without asking.

 

[clbsquared]

DMR (MOT) would be referring to Motorola's DMR "MotoTRBO", in general. Capacity Max is Motorola's name for the Tier III protocol. All three (capacity +, max and connect + all fall under " MotoTRBO".

Here's a pretty good read on Motorola's Tier III introduction.

But usually, DSD+ will display "DMR", "Cap+", or "Con+". So is "DMR (MOT)" something different?

 

[clbsquared]

It could just be referring to conventional DMR using 2 time slots on 1 repeater / frequency pair.

Usually, when that happens (which I see/hear all the time), DSD+ just shows "DMR".

Hello,

DSD+ is indicating DMR (MOT) because the MFID in some of the headers is 16 (Motorola) instead of 0 (DMR Standard). A MFID of non-zero indicates proprietary data.

A Hytera T3 system has both DMR Standard and Hytera Proprietary data. A Motorola T3 system has both DMR Standard and Motorola Proprietary data.

Connect Plus systems use a MFID for Trident Microsystems because they developed it.

Thanks.

 

[kc4mc]

Thank you Eric, that makes sense. Is there a list of MFIDs somewhere posted?
