(5-7-14) Some phone lines on the University of Nebraska campus are out of commission. Construction workers on P Street cut a Windstream cable Monday afternoon, disabling emergency phones, fire alarm lines, elevator call buttons and general communication. With just days left in the school year, some students can't even find out if they're graduating because they can't call that office. UNL has been using Twitter, its website and signs around campus to keep students notified. Windstream says it could be a few days before the line is fixed.
