SONET-4-ALARM everyday

Hi all,

I am getting syslog entries listed below everyday.
I had a TAC case but all I got from CISCO was "it's a dirty fiber".
If that is the case, how a dirty fiber affects us everyday
almost at the same time? I contacted a SONET provider,
they told me that "we do not see any hit". I also see lots of
PATH errors.

any suggestions?
