Hi All
When I do a show interface s0/1 on my 2620 router, I get the following:

As you can see, in the past 19 hours, I have had 293839 carrier transitions on this interface. I have had my service provider test the line, and they maintain that the line test fine - although the first time it was reported, there was a misconfiguration on their NTU...
Anything else that I should have a look at?
Thanks!
