TRS System IDs

[west-pac]

How do TRS get their specific System ID identifier?...6DB, 19E, 157, 262, 346, Etc... Are these identifiers picked out of a hat?.. so far I haven't found any System IDs that have had any obvious connection to the agency/agencies that use the system.

Why? For what purpose? Why wouldn't that be assigned by a system admin?

Because the SysID/WACN should be unique to each system. How else is a subscriber going to distinguish between System A and System B if it were all left up to some random system admin to decide on a random SysID?

I would choose System ID: BAD, WACN: DADEE.

 

[west-pac]

But Sys IDs are duplicated. We've all seen it when searching Sys IDs.

... and no one else would duplicate that...🤣

On the old SmartNet/SmartZone systems, the system ID was the same as the system key. System keys were assigned by Motorola when the system was built in their factory. Idea was that no two systems would have the same ID or system key. Allowing the admin to create their own would cause issues.

Same on my Kenwood NexEdge system. The trunking function is a system license that is purchased. That system license includes how many sites, how many repeaters and other features. The license key for the trunking feature is loaded into the system. The system keys use the same ID.

Their is more to the story. Motorola separates system via the system ID, Harris does it via the WACN. So almost every Harris system has the same system ID, but a different WACN. Motorola seems to prefer WACN BEE00, but uses different system ID's.

It's not that simple, as @KevinC explains. There is more to it than the SysID. A P25 system's full identifier is the combination of the WACN and SysID, not the SysID alone.

When systems get decommissioned, replaced, and/or sold, do the individual repeaters or controller have to be reprogrammed by an authorized dealer, who requests a new Sys ID, if the new owner doesn't already have one?.. what does that process look like?

 

[nd5y]

There is at least one case of two P25 systems in different parts of the country with the same WACN/SID in the database.

Yes, it does happen and there are examples. Not many, but they are out there.

One glaring example is in New Jersey, where towns not too far apart have the same WACN/SysID issued by Harris. I don't recall anyone ever confirming that they share a core, but they do not appear to have any connection to each other.

It's probably an extremely low percentage of systems that get sold off to another agency like that. There is no definitive answer, it depends completely on the parties involved with the sale/transfer of equipment whether they wipe parameters or have them changed.

I know Abilene is correct and is a Harris system. I have no idea if the one in PA is real or a typo. Somebody might want to check. I think I got crickets last time I pointed it out.

The Chester system is correct. Why would you think otherwise? The system has been in the RRDB for a while, surely if it were wrong someone would've pointed it out by now.

I'm too far away to confirm it myself. There is a lot of garbage in the db that admins allowed or missed.

You just can't help yourself, huh? Always looking for any opportunity to **** on the admins. It's getting real old, Tom.

WTH is this??

Why would a db admin allow this? A three-county electric coop is a state agency? This is a repeater input but its listed as an output with no input? https://www.radioreference.com/apps/db/?inputs=1&aid=10441#cats WTH?

The chesco sys id is correct.
