We haven't really noticed a pattern. Although, this latest time the line
died, the amount of time between bounces almost seemed to decrease
logarithmically. First it would bounce every couple of weeks, then every
few days, then every few hours, etc. until it was bouncing every 30-60
seconds. At that point, I told them to do intrusive testing. They claim
they didn't fix a thing but the line has been perfect ever since.

Perhaps those are the cause of the AIS errors (Actuarial Interference of
Service) or the OOF errors (Overdose Of Fava). <g>
