Thanks.  That makes sense.  When we had consistent problems with Comcast 
(occasional loss of dialtone for two years with multiple service calls), 
it ended up being a problem with the connectors out on the street.  The 
tech that figured it out had equipment that recorded the signal 
strength, which was good, and also some sort of error rate, which was 

Most techs, if you're polite, will replace some connectors outside your 
house, and write it up as that being the problem, so that you won't have 
to pay for the service call.  At least that's what I found.
