Do I lose phone service I lose internet?

Do I lose phone service I lose internet?

Is my phone line independant of the modem? If I lose internet do I also lose the phone service. I am considering a Tele-Tech job and they require "hard phone line" independant of internet connection. Please advise.

Re: Do I lose phone service I lose internet?

The CDV is separate from the internet, but still travels over the same coaxial cable from the node.  The internet can go down and the CDV stays up.  If there is an outage with the distribution system due to fiber damage or coax damage from a storm, everything can go down, TV, CDV, HSI.

 

Comcast CDV uses a combination modem / eMTA telephony modem for both services.  The CDV doesn't use the internet, but travels over Comcast's private fiber backbone to a gateway that connects to the public telephone system.

 

If you job requests a POTS line, then that's what you should have installed from your local phone company.
