Update:
The telephone repairman came out today. The problem was outside
the house in the telephone company's lines. My wife was at home not
me so I don't know what the problem was in the telephone company's
equipment. The repairman mentioned work was being done about two
miles from my house that apparently caused the problem.
Interestingly, my connection seemed to be the only one effected.

Paul thanks for posting the update. Sounds like it was a 'cable pair'
problem although two miles sounds like a long way for DSl. Maybe while
phone was out, the DSL 'was getting through' on one side of the cable
pair or through a high resistance cable join in one side of the cable
pair.
