You are referring to upstream SNR faults. These are easier to monitor, and it is reported by the CMTS.Downstream SNR faults tend to affect a lot more frequencies when network related, although that’s not a certainty. There are reports that determine this, although these came along after I left the Network dept so not sure on the processes etc. I would say it’s more likely local to the customer than the network though. The first thing I would do would be tighten/reseat as many connectors as possible. If still not resolved a business engineer would need to attend, and determine if it is a network issue or drop cable inwards and take the appropriate steps
