发明名称 Apparatus and method for a telephony gateway
摘要 A system and method for connecting a circuit network with a packet network. In one embodiment, the system contains a packet switch fabric, a circuit network server, a packet network server and a signal processing server. The circuit network server can send and receive circuit-based signals with the circuit network and can also send and receive packet-based signals with the packet switch fabric. The circuit network server has a digital signal processor which provides packet adaptation. The packet network server can send and receive packet-based signals with the packet switch fabric and can send and receive packet-based signals with the packet network. The signal processing server can send and receive packet-based signals with the packet switch fabric and has a digital signal processor for performing signal processing on the packet-based signals. The packet switch fabric transfers packet-based signals among the packet network server, the signal processing server, and the circuit network server.
