ABSTRACT:
A system for transmitting modern signals across a packet network with improved resistance to bursty network packet loss that includes a first and a second processor, which connect a first and second V.32 and above modem to a first and a second side of the packet network and which provide a modified V.42 error correction using a Link Access Procedure for Modems (LAPM). The first and second processors provide a local interface to the V.32 and above moderns, demodulate a first and second data stream from the corresponding V.32 modems into bits, packetize the bits for transport over the packet network according to an Internet Protocol (IP), and remodulate data streams received from a remote end. The modified V.42 error correction includes a staggered redundancy of packet data, in which the staggered redundancy attaches data from a packet n1to a subsequent packet nL, where L>2.
