Dan, I wrote about this in the January 2020 issue of The Spectrum Monitor magazine.
Motorola Federal Solutions is the owner of the trunked system. They manage the system core for the various federal agencies, who are the subscribers to the system - customers, if you will. This allows the federal agency to have a functional radio system, but it is maintained and operated by Motorola. This was a way for federal customers with limited budgets for a whole radio system to acquire access to a trunked network, but just as a customer that pays for access.
The trunked system core can be connected to various agencies and trunked sites across the country as needed, as long as a network connection can be made to the trunked sites. The system is set up so that the various agencies can utilize it at their facilities and sites, but they are using separate talk groups and have no crossover between the different agencies. Sites can be VHF, UHF or whatever is needed by the customer. They don't really share anything other than a system ID.
