Re: broadband clarification

  • From: Christopher B. Zydel

A cable modem is a modem.  All signalling between a cable modem and a CMTS
is done over an analog carrier using QAM and QPSK modulation schemes.

For example; I'm sure that none of you really think that a cable modem is a modem since it doesn't do AD/DA conversion but we all understand that it's simply a device used to connect a customer to a provider.  After all "cable modem" is nothing more than a marketing term so that customers have a rough understanding of what the device does (not that they always understand that either).

If you consider that to be current DSL/Cable speeds fine.  If you take that to mean some future technology using quantum mechanics fine.
