Hi All, we've had our PM3s on line for a couple weeks now, and I've
noticed that two of our PRIs seem to be generating a lot of errors. I say
"seem" because I don't really know how many errors I should expect to see.
The really-error-prone lines are both on the same PM3, though that's
probably just coincidence.

If these numbers are genuinely high, I'd like to get our telco to fix the
problems sooner rather than later *8-)
