New Jersey Interoperability Communication System (NJICS)

Request for assistance

Guys,

I need a few of you who know & use P25 monitoring software often to run a few days of logging on the main simulcasts that you live in.

We are in the process of cleaning up the NJICS DB entry & one of the things that needs to be re-visited is the NJSP talkgroups that can sometimes appear at the same time on both systems.

The functionality seems to be drastically reduced compared to the months right after the core part of the system came on line. As an example, through both of the last 2 major storms & normal daily monitoring here on the Hunterdon Simulcast, the only thing that gets ported over on a regular basis is the Troop-B 4-COMM and 5-COMM talkgroups (and not all the time, either).

Just because it's possible for the system to cross-connect the 800MHz talkgroups to the 700MHz system, does not mean they should all be listed on the 700MHz side. I want to get as close to 'accurate' of an update about what's really being simulcast, so I need some help from those in Central and South Jersey.

Thanks in advance!

Yeah I noticed that on my last drive up to Bergen County from south Jersey. I had all the NJSP Turnpike talkgroups programmed in on the ICS side and only caught a few transmissions compared to the Smartzone side which I was also monitoring at the same time. I know certain NJSP units have APX6000 portables on the ICS so these talkgroups seem to be set up on affiliation only vs B2-4 which I always hear full time on West Orange Simulcast.

Aren't all talkgroups on the NJSP system technically capable of being used on NJICS depending on radio programming?

 

[APX8000]

Yes and no. I can tell you that the APX6000 had ONLY the NJ ICS sites programmed in, not the Smartzone. It also had all the A, B and C 1-15 talkgroups using the ICS DEC/HEX. However, the system admin can program the system to deny the radio from affiliating certain talkgroups to a site. I want to say I've seen denials on the Union County Simulcast If I recall but it was a year plus ago.

Interesting. I can say that over the past few months, I've heard more and more NJSP talkgroups showing up on NJICS Bordentown and Wall sites.

 

[W2SJW]

After talking with another admin about this & way the system is set up, we're not going to be removing anything for now. In the next few days I'm going to make changes to adjust the talkgroup category names & channel descriptions so that they match in both systems (and that will be all for now - no deletions).

 

[nosoup4u]

The 4213 and 4215 talkgroups have been around for a couple years at least now. They are used for investigations, but who the actual agency is still is a mystery, however it is doubtful that they are NJSP. The radios are usually in the 14500 to 14525 ID range.

 

[APX8000]

Yeah I don't think it's NJSP either. I've never seen those IDs affiliate to any of their other channels. And most of the task forces will use the 20-24 INV channels for the respective troop.

those TG have been in use for over a year. and are quite active. they have never been identified.

Is it true that the NJSP port over to the NJICS isn't total...I'm in Northern Cape May County...If I monitor the 800 MHz simulcast, I get a more ID's and traffic on the 3-Comm East (34896) than I do with the NJICS 2181 3-Comm East.

I receive all of the Troop A 3- Comm 800 MHz traffic but on the NJCIS is looks to be more localized to traffic assigned to southern Atl Co, Upper Twp and Dennis Twp's- all on Hammonton Simulcast and nothing on Cape May simulcast

Cape May simulcast seems to be delegated to Medcom for CMC, Cape May Co Sheriff and Middle Twp PD, but no NJSP traffic at all

As I understood, the NJICS wasn't to be a complete parallel re-broadcast of the 800 MHz system for NJSP, or am I wrong

If there is not a radio affiliated to that talk group on that site traffic from that talk group will not be transmitted by that site.

 

[DougWatkins]

I'm curious...it is a patched re-broadcast ??..they must have figured out how to route certain TG's and ID to different 700 MHz sites...the 800mhz simulcast is blast all of the assigned TG and ID's out

I have two scanners, I was able hear all TG traffic on 800 MHz, but only geographically local traffic on the NJICS while monitoring simultaneously

 

[W2SJW]

It's been mentioned numerous times before, but just as a reminder for everyone, the NJSP and NJICS share the same system controller. These are not 'patches', as the system controller sees everything as 'one big system'.

The system admins have to flag specific talkgroups as being systemwide. Normally, only the NJICS site that the 700MHz radio that affiliated to that TG will carry the traffic (long gone are the days of building a statewide system that blasts all traffic across every site).

[DougWatkins]

Thanks...that clears it up for me

BTW..are there plans to ultimately DC the 800mhz system??

 

[W2SJW]

When the budget allows, the 800 will go to a P25 Phase-II capable infrastructure as well.

I finally figured it out. On the Sentinel I would chose Monmouth County Statewide and find Monmouth and get Howell within the NJICS then AVOID out all other townships but that one. It would NOT receive that way! I had to load the whole thing into the scanner and go town by town using the scanner to AVOID unwanted channels to scan. Very complicated, and now I have to worry every update with Sentinel I have to start over.....

 

[elias1988]

It would be a lot easier just to delete the unwanted departments/towns and keep the ID search turned off.

 

[elias1988]

Just picked up radio 16084 (not listed on the master list but possibly REMU) affiliating to TG 4591 on Bordentown.

 

[bburke_7]

Thanks so much but that didn't work either. Either I'm doing something wrong or their is a link needed with Freehold or Wall. When I include them back into the Fav list I can receive Howell again... Go figure... Thanks again...

Newark and Elizabeth FD's

I am using a brand new whistler 1088. I programmed the West Orange and Union county sites of the 700mhz into my scanner. I am sporadically picking up Newark FD and Elizabeth FD. The transmissions I am picking up are extremely poor quality. The transmissions are all broken up and some drop in the middle of the transmission. I live in Elizabeth. Is there any adjusting I can do to my scanner to improve reception? Only having a problem with the 700mhz system. All other trunking systems function normally. Any suggestions? Thank you.
