The Jackson Parish 9-1-1 communication centre in the US is now using Zetron’s series 4000 communication control system that employs not only an EF Johnson radio to enhance interoperability among different radio types, but also ties into Louisiana’s Project 25 system.
It connects to the state’s P25 system and patches the P25 700 MHz digital radio to the high-band analog radio system through the console.
The new system allows encryption to be switched on and channels changed from the console. The radio can cross-patch the VHF to the digital 700 MHz system so that deputies can communicate with each other, no matter which radio system they’re using.
