New DOCSIS... for the uninitiated.
[link|http://www.cablemodem.com/specifications/specifications10.html|DOCSIS v1.0 Specs]
[link|http://www.cablemodem.com/specifications/specifications11.html|DOCSIS v1.1 Specs]
[link|http://www.cablemodem.com/specifications/specifications20.html|DOCSIS v2.0 Specs]

DOCSIS == Data Over Cable Service Interface Specification

Cable modems pre v2.0 can theoretically run up to 38Mb/sec downstream, and 10Mb/sec upstream.

I don't know if this is the same for v2.0 or not. I'd hedge that it is more. But NOT at 1000 Megabit per sec range.

New What you say makes sense
I need to double check just what speed was occuring.

I am trying to locate the original post. But I can see I am saying
megabytes when I should be saying megabits.

My modem is a Motorola 5100 DOCSYS 2.0 SurfBorad.

This link says that DOCSIS 2.0 can reach 30.72Mbs per channel
