• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Does anyone know if VIPER is scheduled for the P25 Phase II TDMA conversion and if so when?

Thanks

At this time VIPER is scheduled to migrate to P25 Phase 1 FDMA by sometime early next year.
P25 Phase II TDMA is not part of this upgrade process.
I would feel safe knowing that any scanner that can handle P25 Phase 1 FDMA will continue to work for VIPER for the foreseeable future.

VIPER P25 Phase II Migration

As Marshall mentions, there are no immediate plans to migrate the VIPER system to Phase II. Our current target for Phase I migration is 30 June 2014 and at least initially we will remain at FDMA. I anticipate that our controller firmware level will rise to include other features such as ISSI 8000 and CSSI with those being our emphasis in the near future. Factors that will drive a Phase II transition are magnified with a statewide/large user base system since a) greater than 50% of the subscribers need to be equipped with a TDMA capable device and b) the system base station architecture (GTR8000) must be in place to accomodate TDM operation. Given that initially we are simply converting the current Quantar bases to P25 Phase I operation, it is safe to say that for a complete, statewide P25 Phase II rollout, you have plenty of time to get ready.

And I am sure your neighbors :cool: look forward to the ISSI 8000 & CSSI implementation.
