Summary: 
Recently, computer communications, especially Internet services, have become popular and as a result, high-speed network access circuits are now desired. NTT has developed an economical and high-speed multimedia computer network, combining satellite and terrestrial circuits. The satellite circuit transmission rate is approximately 30-Mbit/s. To select IP packets from such high-speed satellite circuits, this system employs the asynchronous transfer mode (ATM) in the satellite section and we have developed a new economical satellite circuit receive adapter (SRA) for the satellite section. This paper describes the system configurations and the key network control technologies for multi-link routing, high speed processing and broadcasting.
