Thanks to Excentis, a leading and solid provider of highly specialized testing, consultancy and training services for access network technologies(cable, xDSL, wireless, etc) and related services (e.g. VoIP and iDTV), we can all have a free DOCSIS Config File Editor.
After some requests, I've updated the library with a few examples of DOCSIS config files and a CMTS running config. You'll need a DOCSIS config editor to view the config files, but the running configs for the CMTS are in text. Also, check out the ANSI document on Digital Transmission I posted. It is a good read on QAM - free from Google if you are interested. Happy New Year everyone.
