Narrative:

I was working east departure. During the above period all medium large transport type aircraft would not track with the ARTS system. This time period was an east departure rush. I was forced to work non beacon procedures (get altitude reports) for all the above mentioned aircraft. The situation was pointed out to the area manager. Approximately 6 aircraft were involved.
