Abstract

L'invention porte sur un système de traitement de signaux qui fait la distinction entre des signaux vocaux et des signaux numériques modulés par une porteuse bande vocale. Ce système de traitement de signaux comprend un central vocal, un central numérique et un discriminateur d'appels. Le central vocal est capable de commuter des signaux vocaux entre un réseau à commutation de circuit et un réseau à base de paquets. Le système de traitement de signaux comprend également un central numérique capable de commuter des signaux numériques modulés par une porteuse bande vocale sur le réseau à commutation de circuit avec des paquets de signaux numériques non modulés sur le réseau à base de paquets. La commutation numérique fonctionne par démodulation de signaux numériques provenant du réseau à commutation de circuit et destinés à être transmis sur le réseau à base de paquets, et par modulation des paquets de signaux numériques provenant du réseau à base de paquets et destinés à être transmis sur le réseau à commutation de circuit. Le discriminateur d'appels permet le basculement sélectif ente le mode vocal et le mode numérique.A signal processing system distinguishes between voice signals and digital signals modulated by a voice band carrier. The signal processing system includes a voice exchange, a digital exchange and a call discriminator. The voice exchange is capable of switching voice signals between a circuit switched network and a packet-based network. The signal processing system also includes a digital exchange capable of switching digital signals modulated by a voice band carrier on the circuit switched network with packets of digital signals not modulated on the packet-based network. Digital switching operates by demodulating digital signals from the circuit-switched network intended to be transmitted over the packet-based network, and by modulating digital signal packets originating from the packet-based network intended to be transmitted over the circuit-switched network. The call discriminator allows selective switching between voice mode and digital mode.
