What does "CCAP Commanded Power in Excess of 6 dB Below..." mean?
"RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW" means exactly what? Often seen with "Dynamic Range Window violation" and "Started Unicast Maint...
Finally, after a ton of tech visits, the ultimate problem causing this issue has been found: A bad cable from the top of the telephone pole (at the tap) running 15' to the base of the telephone pole (ground block).

Got a screen snip of the cable connections page and event logs?
One of the problems is that the cable connections page might look fine. But it only loads a snap shot of when its loaded. If something is causing issues with your line, your power levels might fluctuate. For example, I've seen a coax ran into someones house that rubbed against a tree. When ever the wind would blow to hard, it'd cause power levels to fluctuate at because of the worn area rubbing against the tree. thats just an example. So the cable connections page is the snap shot. the logs are what show longer term issues. LIke the "dynamic range window violation". Thats an indication that the power levels are going out of spec.
So attaching your cable connections page and the logs help us to help you.
Been monitoring power levels via a program every 60 seconds. Rock steady.
