We have a landline, and one of our phones is a plug-into-the-wall-with-a-cord phone. Such phones draw as much current as they need from the phone line, and therefore will continue working even if the power goes out for an extended period of time, so long as the phone line doesn't go out. We've got cordless phones for the rest of the house, which we primarily use, but, even if the power goes out and wipes those out, we've still got the one plug-into-the-wall as a backup.
We also have a cable modem.
We do NOT have our telephone service provided by our cable company on the cable data line. This means that we've got two separate lines of communication to the outside world.
Which is good, because I'm posting this. And our phones are out. Even the plug-in one in the kitchen.
Maybe it's finally time for me to break down and get a cell phone, so I can have three lines of communication.
