I am the Chief of a rural fire department. To receive emergency transmissions from our dispatch center, we need to use a dedicated phone line from the dispatch center to our area because of mountains. The dedicated phone line is installed, and the radio repeater is ready for installation. The problem is, we do not know what equipment is required to convert voice from the phone line to the radio repeater, and how to connect the equipment.
The system also has to work in reverse, i.e. voice transmissions from our fire department members in the field are received at the radio repeater site, and must be converted to voice transmissions on the phone line back to the dispatch center.
I am told this technology has been in use for many years, but I can find no one in our remote area who knows how to make it work.
Help from any one will be greatly appreciated.
