On the database

Some Dispatch is listed as DE
And others TE what’s the difference

Hover over the column header for Mode and it explains the difference.

D = FDMA
T = TDMA

It seemed to me when they have it as DE digital Encryption for Dispatch

And TE is another form of encryption

This is on the nj 700 list

No, I explained what it means. FDMA vs TDMA, has nothing to do with any "form of encryption". Uppercase E indicates full-time encryption, lower case e indicates partial or part-time encryption.

DE = Phase I TGID encryption
TE = Phase II TGID encryption.
Means one is using Phase I , the other is using Phase II on the same system.
Phase II systems can/do use both.

Hope this is a better explanation.

That explanation works fine for P25 systems, however those modes apply to other systems as well (both conventional and trunked), which is why using terms like "Phase I" and "Phase II" is not ideal when explaining the two modes. For example: NXDN is FDMA, and therefore D/DE/De apply to those systems, whereas DMR is TDMA, and therefore T/TE/Te apply to those systems.

Incidentally, not all P25 Phase II systems permit the usage of FDMA talkgroups. I know of a number of systems where only TDMA talkgroups are permitted in order to maximize channel resources.

It is if the OP is talking about the NJICS system. There is a mix of DE and TE TGID's. Nowhere do I see the OP posting about NXDN in his post.

So, why muddy the waters??

To be fair about being fair :LOL:, he did mention "This is on the nj 700 list" which is an odd substitution for NJICS, but I did know which system he was referring to. Still, the thread title and initial post were very vague, and could apply to just about any system type. I was thinking of others reading the thread in the future when keeping it generic FDMA vs TDMA rather than P25 only Phase I vs Phase II. This is why people need to be more specific when posting.

It's a moot point, as the OP said "K thanks" right after my second post, which seems to indicate that he got the info he was looking for.

You know, when someone asks a simple question about what an abbreviation means in the RR database... and the question is answered simply and straightforwardly by a RR database administrator why would we question it or split hairs over "the" answer. :p:p(y).
