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...

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

Hi there...

I'm pretty sure there's some Ubr experts on here ;)

We are migrating a Cisco Ubr7114 up to Ubr7246VXR - so during this we'll be changing to Docsis 2.0 ... this will also involve changing the channel bandwidth from 3.2 to 6.4 Mhz....

My question is in regards to Docsis1.1 modems - if we change the channel size to 6.4 is there a way to support modems that only work with 3.2 channel width (therefore Docsis 1.x)??

Thanks in advance,
