Our links were both down for 87 seconds. Hmm....someone else suggested
that this might be a problem with the DS3-12 cards in the ONS15454. We
have one of those here and there is one in the Qwest CO. I should check
to verify what software level they're using on those cards. I found a
field notice that seemed to indicate that flaky code existed for those
cards that would cause them to errantly send out LOS and AIS frames.

What code has this feature?

Thanks,
