Microprogrammable TDMA terminal controller.

摘要

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 (10) for performing real time burst and data path control functions, transmit and receive high-speed data path modules (12, 14) for interfacing with the modem and terrestrial interface ports and providing direct burst processing of the data, a microcomputer-based operation control (16) and a high stability oscillator (22)
