What is the purpose of the coaxial jack on the ONT I211M-L? On my setup this is connected to a wall outlet jack that goes nowhere! Is this an available outlet that I can use for internet and/or tv service? Thanks.
If you have TV service that is the main feed and would typically go to a cable splitter which would feed the cable jacks throughout your house.
From what your saying it sounds like it is back feeding the jack it is connected to maybe a splitter somewhere else.
As long as you have 100/100 mbps it can also be connected for you internet.
