I am looking to find the best operating range and/or configuration for stability for our plant. Most notably, what you are using in respect to frequency, channel width, and Qam with respect to reducing noise and their relationships with one another. Right now, the best SNR we can achieve is 36.1, on a good day. It tends to be between 30 and 33, but periodically experience drops below 28. At or below 28, we start to drop packets and ultimately get upset customers with intermittent problems. As you can see, there isn't much room for play. I would like to get it to where I can get more of a "window" for problems and a chance to fix the problem before customers tend to notice it. I know this isn't something over night that can be fixed but I am looking for something to shoot for. I would like to see what others are configured at and compare them with what is working and creating targets to reach. Details of our plant are listed below. Any information you are willing to provide or give would be greatly appreciated.
Modems: 968
Version: DOCSIS 2.0
Mod Type: 64 Qam
Frequency: 32 Mhz
Channel width: 1.6
Questions or would like to know other things just let me know and I will find them out.
