Consortium Of Eastern Wayne County MPSCS Migration

[Thunderbolt]

The planned switchover of the communities east of Detroit that are part of the Consortium of Eastern Wayne County, is expected to start within the next few weeks. Currently, these communities are operation on an older Motorola legacy Type-II TRS, known as the Grosse Pointe Intermunicipal Radio System that is at the end of the it's lifespan. This is the official anchor thread for this system changeover.

The switchover by the Conference of Eastern Wayne was to have been this week, but has been placed on indefinate hold. Since federal grant money is being used an environmental and historic impact review is required. This review has not been returned with an approval so no tower work can be completed. Once this review is received the work can continue.

Why would an APCO P-25 system (Grosse Pointe Intermunicipal Radio System) be at the end of it's service life? Sounds like more misuse of those federal dollars, like L.A.?

Why would an APCO P-25 system (Grosse Pointe Intermunicipal Radio System) be at the end of it's service life?

From the description (Analog and APCO-25 Common Air Interface) it is not a full P25 system... P25 like MPSCS cannot do analog.

 

[radioman2001]

So what, if it's a P-25 system it's not THAT old. Not like it's analog only.

 

[rdale]

I'm not sure what you're asking? If their system is no longer being supported by the vendor, it makes sense to join an existing long term system.

In order to bring this system into the MPSCS, it needs to be completely upgraded to fully modern ASTRO 25 standards. Currently, the Grosse Pointe System is using ASTRO Platform 4.1, and the MPSCS is using version 7.11. As such, the former can not work on the latter.

Motorola has stated that they will not be supporting older ASTRO systems that use a 3600 baud data channel in the future. I forget when the cutoff date is, but they are pushing everyone into ASTRO 7.xx and higher in the future. Eventually, the statewide systems in neighboring Indiana and Ohio will upgrade to ASTRO 7.11, most probably when NEXTEL rebanding is finished.

Are they going to reprogram or purchase new radios? The old stuff should still work right?

 

[hfflunki]

will my radioshack pro-106 get the new motorola system
i apoligize if this is a stupid thing to ask but i am kinda new
to scanning i used to only be interested in shortwave

 

[rdale]

Your Pro-106 gets MPSCS fine.

 

[hfflunki]

thanks rdale like i said im new to scanning i got a membership and programming software
i figured out idtracker iii and i think im setup for some scanning
thanks

A decision to upgrade was made because the system controller was beyond end of life. Key components are only availible as remanufactured pieces, if they are availible at all. The system is such that there was not single controllere upgrade that would "drop in" to the system. Rather than wait for a failure that could not be repaired, an upgrade to MPSCS using a grant that covers about half the cost was chosen.

No subscriber equipment is being replaced on the public safety side, but the DPWs will need new subscrber units.

 

[radioman2001]

Got to love it, forced upgrades. Better that what car or computer manufacturers do, just say "no longer supported" and then you have to spend a lot of money for basically the same level of service. As I understand it the only difference between a 3.1, 4.1 and 7.1 controllers is the baud rate 3600 to 9600. I wonder what Motorola will come up with next to force an update in 5 years. It's also mentioned that not all subscriber equipment isn't being replaced, but it's another back door for replacing perfectly good equipment. I hope they auction it off so others who aren't stuck in this upgrade frenzy can benefit. BTW NYC told Motorola that their DOITT system was to be 3600 baud or they wouldn't get the contract.This resulted in a hobbled together system, so I guess Motorola will support 3600 baud if they are forced to.

I agree it's smart for the agency to do the upgrade with Fed money support, but Motorola is in a lot of hot water all over the U.S. for it's sales tactics.

The switchover to MPSCS is scheduled for the week of September 20. Because of space restrictions n the radio room the old system will be taken down and the equipment removed, then the new equipment installed. At the same time subscriber units will be retemplated. During the switch all traffic will be moved to event talk groups.

When will the new Talk groups be available for GP on MPSCS Ron?

As you understand it, is wrong. The difference between a 4.1 controller and a 7.1 controller are totally different. The Difference between 7.1 and 7.11 controllers are different as far as software and number of servers. As far as 3600 and 9600, It would not be a P25 P1 compliant trunked system if it was 3600. If they want to interface with the other system they should be with in 1 or 2 if not the same revision that they want to connect too,,,,, unless using an ISSI.
I would say money well spent,,,they will be very happy with the new system. Not sure y or if they are purchasing there own 7.11 master site, but could be saftey and reliabilty of not wanting to backhaul sites and console links to another Master site. We all know how stable the Telphone comapnaies T1's can be, LOL. And microwave links can get expensive in a hurry. So I can understand that, if it is the case.

You opinion of Motorola forcing them to upgrade, is just that your opinion. And from what has been stated here it does not sound like they are doing an upgrade but a complete system change out as far as the master site goes.

If the NYC DOITT system is 3600 it is not compliant with APCO p25 Phase1 trunking standards simple as that. I would say they wanted a mixed mode capability analog and digital if that is the case, from what you stated.

Testing on event channels showed weak or no in-building portable coverage in GPF using the Macomb and Detroit towers. The data link is microwave from GPF to site 2703(?) in St Clair Shores and back to Northville.

When will the new Talk groups be available for GP on MPSCS Ron?

As far as I know we do not have templetes back yet so I don't know whatTGIDs that have been assigned.

 

[Thunderbolt]

When will the new Talk groups be available for GP on MPSCS Ron?

When someone submits them to us here at the Web site.

All of the police agencies on this system are currently on the MPSCS system on G event 7 TG 1016. No transmissions on the GP system. Unknown about fire at this time. They must be making the move to the new system soon.

 

[gpp10x]

Ok my mistake. I see those are Event TG's
