When I ask the 611 repair they said they would call back in a few
minutes.  They and said that I was correct -- they run line tests
between 12-5:00am.  The repair rep said that she could block my
number.  Its only been a few days now and no more early morning rings - 
if the problem returns I will report back.

By the way the chance that it was a hacker power dailing for a carrier
is very remote because such programs require the receiving instrument
to answer and put up a carrier tone.  In my case, and in the others
reported, we receive one short ring.
