Do radio ids on an edacs system carry over to harris p25?

[mk262]

My county is doing a migration, at some point here. Will the numeric radio ids still look the same on the p25 system?

Obviously I'm referring to the radios that do digital as well, the ones they will carry over with them.

The maximum radio IDs on EDACS is 16,384. In an EDACS-IP network (like the state of FL) the max is 1,048,575.

P25 has a maximum ID of 9,999,999. They could technically keep the same IDs, but its entirely up to the system engineer.

To keep things simple they may just keep everything the same and move over to the new system but while its technologically possible, predicting the future isn't

An EDACS system near me just recently finished it's migration to a Harris P25 system, and for the most part all of the ID's did NOT stay the same.... but.. they kinda did at the same time. For example, RID 4901 is now 14901, 4213 is now 14213... basically they put a 1 in front of each one. So as suggested above, it's pretty much up to the guys programming the system.

Actually, ID schemes would be determined by the agency that owns the system. Some have specific ways of numbering radios so they can tell at a glance who the user is, while others simply start at 1 (or 2500001, or 10001, or 22001, etc etc) and assign the next available number to a radio. The programmers just program the IDs they're given.

Actually, it's 16 million, or 16777215 to be exact.

In P25.. The radio ID's are actually 7 digits.. The System(#),Agency(##),Unit(####) IE" 7030001
EDACS can be whatever

[Unitrunker]

The example you give looks more like the radio ID format for Motorola Type 2 trunking.

I don't think this is entirely true on the P25 end. My county uses a P25 700MHz system and our Radio ID's are 6 digits. Mine for example, is 204961.

Incorrect, it is up to the programmer and system admins to decide this. As pointed out earlier, any number from 1 to 16.7million is valid.

As for 9,999,999 wasnt there an "undocumented feature" in older copies of RPM that only allows harris radios to be programmed with IDs that high? I see that 8B04 allows the whole range but i remember there being issus with our earlier RPM.

[Radioman96p71]

Correct, early versions of RPM (and ProGrammer) limit the ID to 9,999,999. Unitrunker is correct in the 16mil number as per the P25 spec.

How the LIDs will look after the migration is up to the system operator.

System change overs are an excellent opportunity to re-farm the LIDS if new organzations have been loaded, interoperabilty concerns, planning for future expansion or if the user database has just gotten messy.

When my EDACS system migrated the P-25 Agency number was added to the front of existing LIDs and another two digits in front of the GIDs and that was that.
