I have an older Harmonic NSG-40 card without DLM. What would be a good value for the rf-channel network delay in the CMTS? Using a UBR10k with MC3gx60 connected straight up to the Harmonic.
I was wondering if any of you have experience with cable modem 3.0 that suddenly lost Internet connection for sometime, like 30 minutes, one hour or more. I am having that issue with some random clients and when we check their parameters everything is normal, but the clients keep saying the same: they lost connection, even though all the lights on the CM are normal.
Could it be related to load balancing or any misconfiguration on the CMTS? We have an UBR10012, but this is the first time facing this kind of issue.
I would like to have some advice from the community on how to improve our Ubr10k. In my company we want to enable new nodes and I was wondering if is better to still get the most of the MC5X20 card adding other cards and equipments or go for the MC3Gx60V card. Below is an inventory of my Ubr10k, any advice or list of items to improve would be appreciated.

What is the necessary configuration for the CMTS Casa Systems C100G to allow the use of cable modems with an operating frequency range of 5 - 42MHz and other cable modems with an operating frequency range of 5 - 85MHz on the same interface upstream port?
What is the necessary configuration in the CMTS to not assign frequencies higher than 42 MHz
to cable modems that have an operating frequency range of 5 - 42MHz
We use a Cisco UBR10012 with RFGW-1D's which uses cards for the RF. We have seen on occasion these RF cards fail resulting in loss of some downstreams, which wouldn't be a problem except many modems still use these downstreams in their bonding group and it kills their performance. I think they need to be told this channel/group of channels are no longer functioning properly, is there a way I can have the CMTS handle this dynamically? I just want them to remove the no longer functioning RF downstream channels. I've looked at the cable rf-change-trigger command to see if this may work.
I use 6 upstream channels, checking the Utilization Percentage I see that the last two channels of each port have less cable modem online
and less Utilization Percentage , it is not the same as the first 4 channels.
Please help me to have an equal Utilization Percentage in the 6 upstream channels
our cable modems are 8x4, DOCSIS 3.0 (eight bonded downstream channels along with four bonded
upstream channels)
