Due to travel complications that have resulted from the events of the past week, Dr. Robert Lucky, corporate vice president of Telcordia, has canceled his visit to Dallas and several local appearances that had been scheduled for Sept. 21.

Lucky was to have attended a reception that morning on the campus of The University of Texas at Dallas and speak at a luncheon meeting of the Technology Business Council at the Radisson Hotel in Richardson that afternoon.

At this time, it is not known when and if these events will be rescheduled.
