Oops... Did you meant 'Universal Service'? 

Universal Service is what you said above. Lifeline service is another thing 
entirely; it's the ability for the line to stay in a usable state in the case 
loss of electrical power in the customer premises - for instance, in the case 
of domestic accidents or because of natural disasters. It is meant for 
emergency use. In case of power failure the customer has to be able to call 
emergency numbers (think 911). That's why a POTS line has to provide power 
for at least one phone (four is a common 'ring equivalence number', but at 
least one is *required* for the emergencies).

Of course, regulations vary from country to country. The same also applies to 
ISDN, but not in all countries; I believe that the US standard has not remote 
power, but the german does - 95 VDC if I remember the spec. Brazilian specs 
are derived from european ones, and have the same requirement.
