I have Comcast digital cable, digital voice, and internet. I have only 1 TV connected to a cable box?

I have Comcast digital cable, digital voice, and internet. I have only 1 TV connected to a cable box. If I install Tivo on my basic cable TV (no box) do I still need to connect to the phone line?

Since the digital voice is a VoIP, and the cable is connected to the Tivo, why do I need to connect to the phone as well? Asked by dencrowl 41 months ago Similar questions: Comcast digital cable voice internet TV connected box Entertainment > Television.

You need a phone connection because... eventhough, everything comes in on a single Coax cable, when it comes to connecting a phone to your Comcast phone service, you connect your phone to a "converter" box, this is the same with you're Tivo, it needs an actual phone line to be connected. The Tivo doesn't have the ability to internally split-out the phone connection from the cable TV service, the Coax input on the Tivo only "understands" TV signals, not phone signals. And of course the Tivo needs a phoneline/Internet connection so it can get the daily programming updates and software updates.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
