Patent ID: 7042833

Claim:
A system for transmitting modem signals across a packet network with improved resistance to bursty network packet loss, comprising: a first processor that connects a first V.32 and above modem to a first side of said packet network and provides a modified V.42 error correction using a Link Access Procedure for Modems (LAPM), wherein said first processor provides a local interface to said V.32 and above first modem, demodulates a first data stream from said V.32 and above first modem into bits, packetizes the bits for transport over the packet network according to an Internet Protocol (IP), and remodulates a second data stream received from a remote end, and said modified V.42 error correction includes a staggered redundancy of packet data, said staggered redundancy attaching only data from a single packet n 1 to a subsequent packet n 1+L , where 2<L<6.
