Question 1

does it have phone line?

Accepted Answer

WE use the modem for wifi only.  The  modem is installed in another house but someone there said that there are a series of phone jacks in the back. Check the manual on line from the manufacturer to be sure but my guess would be yes. All cable companies offer VOIP

Question 2

Does this modem support wifi connections? Is it compatible with time warner services? What is the difference between this modem and DG950A Arris Touchstone Data Gateway / Docsis 3.0 & Wireless Cable Modem /DG950A

Accepted Answer

I have this specific CISCO modem and Time Warner Internet.  The modem is hooked to a D-Link router that can be used with either cable connections to the PC's or on wireless mode.  Sorry, but I do not have the answer for the rest of your question. Sometimes if you go to the websites of the companies that make those they might have spec sheets available or contact their tech support teams.

Question 3

can  this be used to send Comcast tv signal  to vizio wifi tv?

Accepted Answer

Your cable company should have a list of compatible routers for their service. I got the Zoom because it was one of the compatible routers for Time Warner. I would try to look up compatible routers on Comcast site to confirm if this router is compatible with their service.
