I'm not aware of MSOs configuring their upstreams to attain rates for 9 and 27 Mbps for version 1 and 2, respectively. The numbers you quote are the theoretical max, not the deployed values.

Upstream capacity will still be scarce on shared media as far as I can see. -- Mikael Abrahamsson email: [EMAIL PROTECTED]
