Been doing some research on what levels my modem is suppose to be at and the downstreams are where they need to be but the upstream are low from what i have read about. is there anything i can do to get these to where they need to be at or do i need to cal and get a work order submitted? my modem is a Arris SB6183 and it reporting that upstream is 33.3-34.0 dbmV. From what i have read these levels need to be higher than 35 and they are below that level. (since it doesnt want to show the picture it can be viewed here as well)
FWIW an end customer really can't do anything to fix their low upstream power. An attenuator only makes the figure look higher / prettier as read at the modem, but the way that the upstream system works, the same power is hitting the CMTS as before..
It may not be low at all. The spec varies from local system to local system. It may be that it is just a very clean / noise free return path.
Bottom line; as stated by @CCAndrew , if you are not having any problems, then don't sweat it.
