Verizon Business of Basking Ridge, New Jersey, has introduced a new service that is designed to enable police, fire, and other public safety personnel to communicate directly with one another by radio, phone, or e-mail during an emergency, even if they are using incompatible communications systems. The Verizon Communications Interoperability solution is an IP-based platform that integrates radio, voice, data, and wireless networks so they can operate as a single network. Each organization sets aside a channel on its radio system for use with the solution. When activated, the service uses routers, interfaces, and other equipment to link all the set-aside channels and convert them to IP. The service can be programmed to use prearranged phone numbers and radio frequencies to automatically alert public safety organizations when there is a crisis.
