## Abstract

In this document, the Commission makes changes to the rules adopted in previous order which enabled licensees in the Multipoint Distribution Service (``MDS'') and Instructional Television Fixed Service (``ITFS'') to engage in fixed two-way transmissions. These new rule changes further enhance the flexibility of MDS and ITFS operations by making certain technical modifications and by extending the streamlined application processing system to ITFS major modification applications.
