The Intelsat TDMA/DSI system
Abstract
The Intelsat 120-mbit/s time-division multiple-access (TDMA)/digital speech interpolation (DSI) system is described. This system consists of TDMA traffic terminals, TDMA reference and monitor stations, and an Intelsat Operations Center TDMA Facility (IOCTF). System performance requirements with associated modem characteristics are provided. An overall system description is given illustrating the burst and frame format and explaining the acquisition and synchronization functions. The paper discusses the technical characteristics and interworking of the reference stations and traffic terminals, and describes the traffic terminal interfaces, including DSI. The IOCTF and its coordination functions, such as synchronous burst time plane change, are explained.
