METHOD AND DEVICE FOR MODEM RELAY TERMINATION

摘要

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 Reliable Protocol Transport (SRPT) 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 aggregato r 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 processi ng path in which digital processing (DSPs) would otherwise have to perform mode m protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point.
