[c-nsp] Ubr Docsis 2.0 Question

[Paul Stewart]

Thank you for the response... I didn't see this being possible but somewhere
someone had told me you could run it that way.... only way I could see is
3.2Mhz width with Docsis 2.0 being backwards compatible ... thanks again for
the confirmation...

Paul

Hi Paul

No, of course not. Your DOCSIS 1.x (TDMA) modems will only support
channel-widths up to 3.2 MHz. If you want use the benefits of a 6.4 MHz
channel-width you need to use DOCSIS 2.0 modems (ATDMA).

cheers,
michel
