Abstract
A radio transceiver system (100) includes an option board interface (117) with an analog interface (119) and a digital interface (125). Option board interface (117) is used for conveying information between an optional memory board (133) and a digital processing unit (105). Option board interface (117) also controls analog audio functions through analog interface (119). Option board interface (117) enhances functional operation of the radio transceiver system (100) by allowing options to be selected which are not provided as standard radio equipment.
