We get random errors on our lines (shown below) and have been told by
our telco that they are "normal" and "nothing to worry about". They
usually don't accumulate, but I think that if they happen every once in
awhile, that is a problem. Any comments on this would be greatly
appreciated. Here are the errors shown:

cs2> sh line1
---------------------- line1 - T1 Inband DS0 ---------------

I read all of the errors to them, and of course, they say its a natural
occurence... Thanks in advance..
