A Computerized Mobile Two-Way Radio System is provided having microprocessor enhanced capabilities and versatility for wide area/multiple region two-way radio networks with multiple categories of users and adaptability to multiple international standards and mobile radio equipment configurations. The main elements of the system consist of (1) a microprocessor-based Control Unit, (2) a Digital Serial Interface/Link and (3) a microprocessor-based Convertible Transceiver Unit. The Control Unit provides many facilities and capabilities for the operator and the system in compact form. The Interface/Link provides a two-way path for serial data consisting of digitized audio and digital command and status signals. The Transceiver Unit is designed for operation and control over the Digital Serial Interface/Link. The system allows the addition of many options, capabilities and peripheral/extenal devices including builtin front panel or remote programmability, built-in autodiagnostics, remote takeover of controls, remote memory-dump, remote diagnostics, program cloning capability, voting on all channels, 512 channel (expandable) programmability within 16 groups (expandable), triple levels of priority within each group (expandable), supreme over-ride channel, RS232C Interface Ports for data applications, phone patch for voice and for world-wide telephone linkable devices and other capabilities.
