TIME DOMAIN MULTIPLE ACCESS BROADCASTING, MULTIPOINT, AND CONFERENCING COMMUNICATION APPARATUS AND METHOD Abstract A method and apparatus are disclosed for conducting broadcast, multipoint, and conference communications in a TDMA network at various data rates while simultane- ously conducting point-to-point communications at other data rates, either between local ports or between geographically remote ports during time intervals within a TDMA burst, which are not necessarily predefined. The disclosed apparatus appends a direct destination address to each point-to-point port communication for trans- mission over a communications link, to directly address the intended destination port. The disclosed invention appends an indirect destination address to each broad- cast communication transmitted over the communications link. A broadcast memory is provided at the receiving end of the communications link, for storing correlated direct addresses which are accessed by the indirect destination addresses, to directly address a plurality of intended destination ports. In this manner, both point-to-point and broadcast-type communications can be carried out for a variety of data rates, during time intervals which are not predetermined within the TDMA burst, and with a high degree of connectivity.
