Does Power Line Carrier work during power outages?

["chris" <chris@xxxxxxxxxxxxxxx>]

Hi,

Does PLC still work when there is no AC power on the line - i.e. during
a power outage?

When I say "PLC", I mean PLC in general - I'm not referring to just one
particular prototocl (such as X-10).

I realize that the answer may depend on the PLC chipset/standard used.
If you know the answer for a specific chipset, please let me know.

Here's why I'm asking - suppose I have a PLC device such as phone jack
extender and suppose it has battery backup. I would want that device to
work during a power outage...


Thanks.


Chris.
