Hi good day
I have a problem with my cm3 c3 arris which is the next problem is that my cable modem stopped taking downstream and previously it was working it should be mentioned that I have another c3 in production and this works normally. My question would be if there is any way to do a general test of all parts of the cmts as a diagnostic sheet? Or if it could be some component of the cmts like some card? since my upstream interfaces work when activated, they are activated without problem but the problem is that the modem cable does not take downstream has this ever happened to you? I currently have a motorola modem cable connected with a coaxial cable from the downstream port and a coaxial cable from the upstream port, all this to a spliter of 2 outputs, thus combining both channels with rf attenuators but still does not take any synchronization with the cable frequency configured in 1/0 cable
Then I share the configuration of my cable interface
