In this paper, NTT's Satellite Digital Communication Service (SDCS) is proposed and discussed. Differing from the conventional digital satellite communications systems offering broad-band digital transmission links directly between subscribers, the proposed service offers a TDMA (time division multiple access) channel to a designated user group using 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)'.
