Acknowledgements

Thanks to the Domestic Network Association for giving permission to install the far end of the pilot AuDSL line at their POP.

Thanks to Jacques Fourie for contributing FreeBSD audio support code.

I also wish to thank the authors of the following software packages, which have been of great help in writing AuDSL:

Tcl/Tk and SWIG, used by the modem status monitor GUI.
Ptolemy, which was used for some early simulations of PR-PAM modulation and adaptive equlization.
gEDA, for drawing the schematic of the hybrid circuit.
Tkpaint, for drawing block diagrams.
