First of all DSL is not pots.

Traditional voice services run on a subscriber loop which is a pair 
of copper lines running from the central office to the customer end point.

This analog voice service is almost always backed up with a bank of 
batteries so that the service continues to run in the event of an 
emergency.

DSL is a data service that runs on the subscriber loop at the same time as 
the voice service.  This service is not required to be battery backed and 
will invariably stop working when power is cut at the customer end point.
