(We've stopped buying 4x4 modems now as 8x4 are just as cheap)
Our config is to split the 20x20 card into 4 service areas, with 4 primary DS (1 DS connector) per service area
5th DS connector is then spanned across all 4 service areas
So D2 modem will lock onto 1st (of 4) visible downstreams, and CMTS will use load balance to move modem to one of the other 3 DS if needed
4x4 D3 modem will lock onto all 4 primary DS. Access the internet, but cant access our IPTV.
8x4 modem has multiple bonded groups.
First is 8 way which includes the 4 primary DS plus 4 spanned DS (used for Internet)
Second is 4 way spanned DS (used to IPTV)
So the spanned downstreams primarily are used for carrying IPTV, but any spare capacity is then available for 8x4 modems to use for Internet
I have ubr10K with MC20x20V
We run D2 modems, 4x4 D3 modems, 8x4 D3 modems

Hello mbowe,
could you share that running config?
Thank You,
