ABSTRACT:
A high speed decoder for recovering a digital data stream from an analog signal transmitted to said decoder via an analog local loop connected to said decoder. The decoder includes an interface to said local loop. The interface produces an input signal in response to the analog signal. An inverse filter is coupled to the interface. The inverse filter provides a compensated signal in response to the input signal. A converter is coupled to the inverse filter. The converter operates to convert the compensated signal into a sequence of codewords, in which each codeword in the sequence of codewords is associated with a codeword utilized by a digital telephone network. In addition, a decoding method for high speed data transfer over a connection that includes an analog subscriber loop. In a processing environment that includes a processor coupled to at least one memory structure by a bus, the decoding method includes receiving a signal from the analog subscriber loop. The received signal is filtered to invert a transformation performed in the connection, thereby providing a compensated signal. The compensated signal is converted into a data stream. The conversion utilizes a set of codewords in which each codeword in said set of codewords is associated with a codeword utilized by a digital telephone network.
