This paper presents NTT's Satellite Digital Communication Service (SDCS). Differing from conventional digital satellite communications systems offering broadband digital transmission links directly between subscribers, the SDCS offers a time division multiple access (TDMA) channel to a designated user group utilizing signaling bits with which TDMA bursts are controlled in the ON/OFF mode. This new SDCS channel assignment scheme is currently providing a loop network called the 'Multi-Access Closed Network (MAC-Net)'. Focus is placed on its configuration and subscriber/SDCS system interface conditions.
