LMRN Technical Data Discussion

[mbstone99]

The database has TG 20695 as being Simcoe / Norfolk EMS.
I believe it should be as follows

20695 Brant and Brant county EMS
20696 Haldimand/ Norfolk including Simcoe

I say this as 20695 is very active mostly on the Brantford Tower, and 20696 is active on the Simcoe and Cayuga Towers.
I have been listening to OPP incidents that require ambulance, and followed the EMS TG that was dispatched.

I also have a list of unknown TG that I believe to be the hospitals as they show up during patches.
24101, 24102, 24104, 24105, 24106, 24107. I just need to reference them to the individual hospitals.

I would have to agree with this. Back in the FleetNet days you would always seen Haldimand/Norfolk TG showing up on the Hamilton tower but barely would see the Brantford TG. Currently I do see 20696 appearing on Hamilton's tower all the time where 20695 you barely see that much of.

I let the LMRN System run for a couple of hours on the Niagara Falls, Fort Erie, Fonthill sites and this is what I logged.

I am not sure if 20692 in the DB is correct for City East.

I am seeing the following in my DSD logs 20690 258 hits, 20691 24568 hits, 20692 41627 hits

Now If they used the same TG layout as they did on FleetNet.. that would make 20690 is Hamilton CACC, 20691 Hamilton East, 20692 Hamilton West

I believe that Matt is correct. The TG pattern matches the old FleetNet pattern.

20698 I saw patched with another talkgroup yesterday, one of the likely Hospital patches

It's gotta be whatever they call Hamilton Tac4 On Scene on PSRN

 

[sensationalseagull]

I've been monitoring the Woodlawn tower on PSRN and FleetNet. For the Hamilton talkgroups on FleetNet, I was mainly getting HAM City East and HAM Tac 4.

For PSRN, the two busiest talkgroups are 20691 (City East) and 20692. My theory is that 20692 is Tac 4 and not City West, as I have never had a hit for City West on the Woodlawn Tower.

If they used the same layout as Fleetnet I'm assuming it would be based on the ascending talkgroup number. Therefore, City West would be after HAM Tac 4 anyways.

Fleetnet:

35584	HAM CACC
35600	HAM City East
35616	HAM Niag North
35632	Simcoe Norfolk
35648	HAM Tac 1
35664	HAM Tac 2
35680	HAM Tac 3
35696	HAM Tac 4
35712	HAM City West
35728	HAM Niag South

PSRN:

20691	HAM City East
20692	HAM Tac 4

But they did reverse the layout for the Cambridge talkgroups, so they could have done the same here as well.

I was looking at my DSD and noticed this..
Channel 0-828: 142.215 DATA

Is this channel that sends out data out regarding the system? I have not seen this channel active in my channel activity in a long time. I do see 142.2150 active with P25 voice but no Data channel. 142.8000 is the CC and 142.3500 is the SCC with 142.2750 & 142.6350 are voice channels.

Matt

I am seeing that the missing DATA channel has resurfaced and is now on channel 0-884 142.6350. Let's see if that makes any difference for mine and EJB's issue with this system.

I figured out some more information on the Cambridge talkgroups.

They've stopped base paging on 149.440 and switched to dedicated talkgroups. Each station has a dedicated talkgroup that Cambridge CACC simply broadcasts on for base page outs. I haven't seen any call alerts. The talkgroups are in the 24000 range.

Based on this map I made a while ago, the Woodlawn tower location, and which dispatcher uses which talkgroup, I've narrowed down the talkgroup to roughly which location. I've also managed to identify one talkgroup (ambulance was pulling out and correlated with DSD logs):

Stations in Guelph and Rockwood:
24004 GW
24014 Guelph - 0 Base - Elmira Rd Station
24015 GW
24026 GW

Stations in Cambridge (south of Grand River):
24000 Cambridge
24007 Cambridge
24009 Cambridge
24018 Cambridge

Stations in KW (north of Grand River)
24001 KW
24006 KW
24010 KW
24017 KW
24023 KW
24024 KW

I also identified some hospital talkgroups, which are in the 23000 range:
23001 Guelph General Hospital
23007 Cambridge Memorial Hospital

23002 and 23003 are one of the either two hospitals in KW (St. Marys and Grand River). Can't figure out which is which yet.

Also, 20620 is CAM CACC. A couple of Guelph/Wellington units switched to CAM CACC on FleetNet accidentally so I just correlated it with DSDplus logs.

Also, here are the Cambridge talkgroups used for hospital patches. I don’t know what the names are, so I’ll just list them here.

20627 - Hospital Patch for Cambridge 1
20628 - Hospital Patch for Waterloo 2
20629 - Hospital Patch for North 1

Note that there are now 3 patch talkgroups on PSRN compared to 2 on FleetNet.

 

[Forts]

This jives with what I'm seeing from London CACC. 23xxx seem to be hospital groups, where 24xxx are station paging groups.

 

[gary123]

Same here. 23xxx are hospitals 24xxx are the EMS stations.

 

[mciupa]

I re-read the pages of this thread to gather info for Hospital Patches and EMS stations. I was afraid we would lose the info and made those two subcategories in the database. We are at a disadvantage for exact names at the moment because full encryption is used.

What I have done is used their geographical locations to jump start the identification process. If you are confident of a proper talkgroup name, please submit it.

Found Stratford.
23104 - Stratford General (RID 752173) EMS unit working the patch (RID 750799)
24199 - Stratford EMS Station (no RID captured)

For those working on the hospital and EMS station lists there should only be one RID assigned to each of the TGs. By monitoring the Patch activity we should also be able to trim down the EMS unit to what city? or station its working out of.

 

[Forts]

For the smaller areas, yes. Kind of tough for London etc. I was able to identify Strathroy hospital because I was at a call with them and figured they would do a patch after transporting. Made note of the time and it was the only patch that showed up on UT during that timeframe.

 

[gary123]

That is the trick. Be in the right place at the right time. That is how I got the Stratford info. Additionally EMS units can be identified by seeing them arrive or depart the station/Hospital and reading the unit number from the fender.

Heard Mississauga CACC telling Halton EMS to switch to Tac1 and 2.
Tg 20822 just became active on PSRN.

I didn't record what I heard and was too late, but I have a few units leaving hospitals being told when they go to base they are gonna switch to the new Talkgroups. I'll try to fill everyone in on where they're going.

But 20822 has to be one of Miss CACC, 821 @ 822 are probably Halton N and south.

 

[EJB]

Halton EMS were told to switch to Tac 2, Oakville and Burlington anyways.
I'm still hearing Milton and Halton Hills on FleetNet

They were told that it's Mississauga Tac 1-3 and asked units to check portables and main radios.

Not sure about Peel region but Halton South is gone, i managed to record.

If anyone wants to submit go ahead

 

[VA3ADP]

Just heard on Tac 5 for 3089 to switch to SERV1 before switching to Peel North. Maybe their switching today or soon?

Could very well be, I can't scan Peel EMS.

I heard what I think was Halton North being asked to switch to something on LMRN. If I see or hear anything I'll reply.

This might be a stupid question. Would Halton North units not affiliate with the Hamilton PSRN tower? We used to see a lot of Brant Co EMS on FleetNet Hamilton, but I don't see their talkgroups anymore. They are on the fringe of the reach of Hamilton tower as is Halton North. Maybe Halton N now will affiliate with Britannia, Ballinifad PSRN going forward.

 

[VA3ADP]

The dispatcher on TAC 2 just advised south units to switch to the new "Southeast" Channel on both mobile and portables. Still hearing calls in the North and Toronto CACC is still active

 

[VA3ADP]

Sounds like all Peel/Halton units have switched over. It was fun while it lasted
