A portable communications device (200) and accessory system which provides full-duplex asynchronous communications between a portable communication device (200) and external accessories (214) over a synchronous digital interface (215). The system includes a digital signal processor (208) for generating a first synchronous digital voice signal, a UART (232) for generating a first asynchronous data signal, and a microprocessor (210) for generating a synchronous control command signal. The system further includes a first multiplexer (236) for multiplexing the first synchronous digital voice signal and the first asynchronous data signal and the synchronous control command signal onto an interface line (215). The interface line couples the communication device to the at least one external accessory (214). A second multiplexer (242) is coupled to the interface line (215), for routing the first synchronous digital voice signal and the synchronous control command signal to the at least one synchronous internal device (217), and for routing the first asynchronous data signal to the asynchronous internal device (230).
Appareil (200) de communication portable et système accessoire qui assurent des communications asynchrones en duplex intégral entre un appareil (200) de communication portable et des accessoires (214) externes, grâce à une interface (215) synchrone numérique. Le système comporte un processeur (208) à signal numérique qui génère un premier signal vocal numérique synchrone, un émetteur-récepteur asynchrone universel (UART) (232) qui génère un premier signal de données asynchrones et un microprocesseur (210) qui génère un signal d'instruction de commande synchrone. Le système comporte en outre un premier multiplexeur (236) servant à multiplexer le premier signal vocal numérique synchrone, le premier signal de données asynchrones et le signal d'instruction de commande synchrone sur une ligne d'interface (215). La ligne d'interface couple l'appareil de communication du ou des accessoires (214) externes. On couple un second multiplexeur (242) à la ligne d'interface (215) dans le but d'acheminer le premier signal vocal numérique synchrone et le signal d'instruction de commande synchrone vers l'appareil ou les appareils internes (217) synchrones et d'acheminer le premier signal de données asynchrones vers l'appareil (230) interne asynchrone.
