Abstract
A modem data aggregating gateway that supports modem relay functionality for permitting reliable switching of modem traffic between a VoIP network and a data packet switch Internet Protocol (IP) network, s.a. the Internet. The modem relay aggregator may receive modem data encapsulated as Voice over IP (VoIP) data packets in accordance with a Simple Packet Relay Transport (SPRT) mechanism. The packet data may be error corrected and/or decompressed before being repackaged for forwarding to the ultimate destination. In the event that the destination is itself an IP device, the modem relay aggregator may forward the packets directly over the IP network. As a result, if the destination of a modem call is an IP device (such as a Web site or other Internet-enabled device) the technique eliminates two points from a processing path in which digital signal processing (DSPs) would otherwise have to perform modem protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point.
