ABSTRACT:
Embodiments of the invention include a system and method for providing high quality voice/sound communications over a local loop of a telephone network. The method aspect of the invention comprises receiving a voice signal, digitizing the voice signal into a high quality voice signal, utilizing sampling rates greater than 8000 samples per second and/or sample sizes greater than 8 bits per sample, negotiating voice processing characteristics between a customer premises equipment and a network element such as a softswitch, receiving speech from a user at a customer premises equipment according to the negotiation, converting the received speech into high bandwidth signal and transmitting the high bandwidth signal to a telephone local loop, transmitting the high bandwidth signal from the local loop to wideband node that packetizes the high bandwidth signal for transmission to a packet network and receiving the packetized signal from the packet network at a switch that switches between an on-network or off-network status. A voice over IP platform may also be used to route packetized signals from the packet network to either the telephone network or another packet network.
