ABSTRACT:
A microprogrammable TDMA terminal controller is of modular construction. Frame reference and burst synchronization timing are resolved to the symbol level by a split frame counter, and a control RAM is reprogrammable "on-the-fly" to permit easy changes in terminal traffic assignments. The terminal controller includes a microprogrammed RAM controller for performing real time burst and data path control functions, transmit and receive high-speed data path modules for interfacing with the modem and terrestrial interface ports and providing direct burst processing of the data, a microcomputer-based operation control and a high stability oscillator.
